Description
    TECHNICAL FIELD
  • [0001]
    The present invention generally relates to mobile devices, and more particularly to systems and methods that employ various mechanisms that selectively disable mobile device functionality to prohibit unauthorized access to information stored within mobile device memory.
  • BACKGROUND OF THE INVENTION
  • [0002]
    In today's world, the use of mobile devices (e.g., cellular phones, personal digital assistants, handheld PCs, etc.) has become a standard form of maintaining communication with others as well as a means to store data important to the user. The information stored on such devices can relate to personal or business data such as social security numbers, phone numbers, addresses, bank account numbers, credit card numbers, etc. Due to technological advances in memory storage capabilities proportional to memory size, a mobile device is capable of storing large amounts of information.
  • [0003]
    Thus, the information contained in an individual's mobile device can be extremely user specific and as a result contain highly sensitive information related to the device owner. As a consequence, an unscrupulous user who finds a lost or misplaced mobile device can misuse the information stored therein. For example, a mobile device can contain information that is user-specific but not readily usable unless such data can be correlated with other information. Such data can be tied to the original user providing an easy means for the unscrupulous user to commit identity theft, which can result in loss of money, ability to obtain credit and other damaging affects to a device owner. Such a misuse of information can be a major inconvenience to the device owner and thus is undesirable.
  • [0004]
    By the nature of their design, mobile devices have several properties making them more vulnerable to loss. They are compact and can be carried everywhere by the user to provide instant access to the information contained within the device. Since the information in the devices can be highly sensitive, there exists a danger that someone who acquires the lost device will have access to all the information contained within. In the hands of an unscrupulous user, this information can be misused to facilitate identity theft. Such a misrepresentation can allow the unscrupulous user to obtain credit cards and other resources and to employ such resources to the detriment of the mobile device owner.
  • [0005]
    Additionally, user specific information can be contained on the device to allow personal data to be correlated to other stored information such as social security numbers, bank account numbers, addresses and the like. Correlating such data can help an unscrupulous user create a fictional identity as though they are the original user. In view of the technology available today, financial transactions do not require a high level of security between a debtor and creditor. In fact, little more than a person's name, billing address and social security number is required to correlate to a credit card number in order to purchase goods in today's technology rich commerce. Thus, by simply accessing some personal data related to the device owner, the unscrupulous user can assume the device owner's identity and inflict financial hardship or other deleterious consequences to the device owner's personal life.
  • [0006]
    One conventional method currently employed to provide a security means is to password protect access to the mobile device. Such a measure requires the password protection to be invoked to prevent access to any of the device's functionality. In order to gain such access, a password must be entered to allow the user to utilize the device's functionality. However, such protection can be insufficient for a number of reasons such as forgetting to invoke the protection, simply entering an easily decipherable password (e.g., 123) to overcome the protection or simply not invoking such protection because it creates an inconvenience for the user.
  • [0007]
    As noted above, the mobile device provides a convenient means to allow a device owner to structure their life. However, such a device will most likely be small to provide convenient mobility and thus, easily lost or forgotten. Since the mobile device is subject to a high degree of being lost or misplaced, and such a device may contain highly sensitive information, there exists a need to have a method or system to protect such information from access by an unscrupulous user. In addition, it is desirable to have such a protection mechanism be easily invoked to provide a fast and convenient means to protect sensitive data.
  • SUMMARY OF THE INVENTION
  • [0008]
    The following presents a simplified summary of the invention in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some concepts of the invention in a simplified form as a prelude to the more detailed description that is presented later.
  • [0009]
    The present invention relates to systems and methods utilized to prevent unauthorized access to information stored in a mobile device such as a cellular phone, personal data assistant or handheld computer, for example. Such stored data can contain personal and/or highly sensitive data such as social security numbers, bank account numbers, credit card numbers, phone numbers, addresses and the like. The mobile device can employ a plurality of techniques to disable the functionality of the device and thus, prevent access to the device memory to mitigate any damage (e.g., financial) suffered as a result of identity theft or related criminal acts.
  • [0010]
    In one aspect of the present invention, the mobile device memory is disabled via a signal transmitted from a network employed to provide wireless communication to the device. The signal can be transmitted after the network operator has been notified. Such signal can be sent one time, on a continuous basis or on a user defined periodic basis, for example. In addition, a signal can be sent from the device to the network to provide confirmation that the device memory has been disabled.
  • [0011]
    In another aspect of the current invention, the signal can be utilized to trigger preexisting security features contained in the mobile device. Such features can include disabling the keypad, blanking out the screen display and/or sounding an audio alarm to indicate a theft has occurred.
  • [0012]
    In yet another aspect of the current invention, an audio signal can be triggered to notify the device owner of the location of the device. Such a feature can be employed when the owner believes the device has been misplaced and wishes to locate such a device. Such a signal can be activated via the Internet or telephone call to the network operator, for example. The owner can activate the signal immediately after losing/misplacing the device to locate the device itself or locate the device and the person currently in possession of the device. Such an audio signal can be used to signal strangers (e.g. persons who have no knowledge of the theft) and/or law enforcement personnel to apprehend the party currently in possession of the device.
  • [0013]
    In yet another aspect of the current invention, the device can employ a tracking device, such as a global positioning system or homing beacon to track and locate the lost/misplaced mobile device. In this embodiment, the mobile device can be tracked located to facilitate recovery of the lost data and to provide criminal ramifications for the possessor of the lost device.
  • [0014]
    In still yet another aspect of the current invention, sending a pre-determined code via the wireless network can disable the device memory. For example, if the mobile device is a cellular phone, the memory security can be invoked via the caller ID of the phone as it displays the source (e.g., pre-set phone number) of the incoming call. Alternatively or additionally, an alphanumeric message (e.g., text message) can be sent to the device via the wireless network to invoke the memory disabling security feature.
  • [0015]
    In yet another aspect of the current invention, device memory access can be disabled after a first attempted use by the current user after the network operator has been notified. The memory disabling feature can be invoked by placing a phone call, sending and email or any other attempt at utilizing the lost/misplaced mobile device. The feature can also be invoked via the use of other features of the device that do not relate to outside communication such as a planning/calendar function, calculator, phone book, address book and the like.
  • [0016]
    In another aspect of the present invention, a third-party signal outside the wireless network can be utilized to invoke the memory-disabling feature. Such an embodiment can be employed when the mobile device is outside the reach of the wireless network, and yet still is open to unauthorized data access by the current user. Such a network can be implemented via a satellite network or some other equivalent that can maintain constant communication with the mobile device regardless of location.
  • [0017]
    In another aspect of the current invention, data from the mobile device can be uploaded via the network and sent to a desired location for subsequent retrieval by the mobile device owner. This particular embodiment is utilized to go beyond simply preventing others from accessing personal and/or sensitive information. This feature can be employed to retrieve data from the device that is difficult to reconstruct such as for example, individual cell phone numbers (which cannot be looked up via directory), addresses and the like. Such uploaded data can be accessed via the Internet, an operator location or stored in a remote location, for example.
  • [0018]
    In yet another aspect of the present invention, the data stored on the mobile device can be erased from the device memory completely. This embodiment can be employed after the data as been uploaded from the device memory if desired. Memory erasure can be invoked utilizing at least one of the aforementioned methods and/or systems.
  • [0019]
    In still yet another aspect of the current invention, at least a portion of the data the device owner wishes to store can be stored remotely. Such data can be stored remotely based on the importance and/or sensitivity to the owner of the device. In this embodiment, the device owner can utilize a user name and/or password to access data stored remotely on the wireless network employed with the mobile device. Thus, the data can be retrieved and access can be denied any unauthorized user as soon as the network operator is notified.

  • DETAILED DESCRIPTION OF THE INVENTION
  • [0031]
    The present invention relates to systems and methods that selectively disable mobile device (e.g., cell phone, PDA, handheld PC, laptop computer, etc.) functionality to prohibit access to portions of information stored therein and/or in connection therewith. Such information can be user specific, for example, highly sensitive and/or personal data such as bank account numbers, social security numbers, credit card numbers, addresses and the like. Thus, the present invention can disable access to the device to prevent unauthorized access to data stored in device memory. It is to be appreciated that the present invention can be employed in relation to any number of systems and/or environments to inhibit the functionality as desired by the user. In addition, the subject invention can limit the functionality of such a system in a plurality of ways including disabling the display, disabling any peripheral input devices to the target system and disabling specific functionality (e.g., access to the target device memory), for example.
  • [0032]
    The present invention is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It may be evident, however, that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing the present invention.
  • [0033]
    FIG. 1 illustrates an exemplary system 100 that can disable and/or limit functionality of a target device employed in conjunction with the subject invention. The system 100 comprises an input component 110 (e.g., mobile device antenna) that receives and conveys a notification signal to a disabling component 120. The signal can be employed to initiate disabling and/or limiting the functionality of a target system (e.g., mobile device) via a control signal sent to an output component 130. This control signal can be employed to limit functionality of the target device to prohibit unauthorized access to data stored locally in memory, for example.
  • [0034]
    The signal initially sent to the input component 110 can be generated in a multitude of different manners such as a signal, message or bit. In one embodiment, the input component can accept a message from an outside source to trigger the disabling component to begin operation. For example, if the target device is a cellular phone, a call from a pre-defined number can be placed to and the caller ID can be employed to trigger the disabling component. Thus, if the phone is lost and subsequently found by an unscrupulous user, the memory of the device can be protected by way of a simple phone call.
  • [0035]
    In another example, the target device can be a personal digital assistant (PDA) associated with a wireless network service. An email message can be sent to the device to instantiate the disabling component 120 to prevent access to any data contained in the PDA's memory. As discussed below, the output component 130 can interface to a plurality of devices such as laptop computers, handheld PCs, notebook PCs, PDAs, cellular phones and the like.
  • [0036]
    The input component 110 can receive information from wireless networks, keypad entries, pre-defined user inputs, etc. Such inputs can be originated by the original user of the target device or the wireless network operator, contain any amount of information and be represented in various formats such as an ASCII string, one or more bits or a signal.
  • [0037]
    The disabling component 120 can be a microprocessor, a switch, a relay and so on. In other words, the unit can trigger the limitation of the target device by simply disabling some access to I/O of a microprocessor, for example. Further, the disabling component can be executable code employed in the operating software of a target device (e.g., palm software in a PDA, proprietary software in a cell phone, Windows software in a handheld PC, etc.). In this manner, the software can be written to execute the disabling component 120 when a specific input is accepted by the input component 110.
  • [0038]
    It is to be appreciated that the input component 110 is coupled to the disabling component 120 and can interface with the disabling component 120 in a plurality of ways. For example, the disabling component 120 can reside in a notebook computer which is connected to a wireless network. In this example, the input component 110 can be located at the network operator's control center and communicate to the disabling component 120 via the wireless network.
  • [0039]
    The output component 130 can take a plurality of forms as dictated by the location and form of the disabling component 120. For example, the output component 130 can simply take the form of an output in a microprocessor wherein the disabling component 120 is executable software. In another example, the output component 130 can be a signal sent from a cellular network to a phone connected to such a network. Once the disabling signal is sent to the phone (e.g., target device), the functionality of the phone will be limited.
  • [0040]
    FIG. 2 illustrates an exemplary system 200 that shows a plurality of disparate target devices can be employed in conjunction with the present invention wherein communication is facilitated with the target devices via a wireless network command 205. Such target devices include a handheld PC 210, notebook computer 220, laptop computer 230, PDA 240 and cell phone 250.
  • [0041]
    The target devices receive a signal from the wireless network command 205 to disable the memory and/or limit the functionality of the device. The signal sent to the device can carry the disabling command or simply trigger such a disabling command locally at the target device, for example. Such a local command could activate a security feature inherent in the device. For example, a voice lock feature can be activated utilizing the disabling signal sent from the wireless network command 205.
  • [0042]
    It is to be appreciated that although the devices are shown receiving the command via wireless network, such a command can be sent in any desired manner. For example, the device could be connected to a land based network (e.g., LAN, WAN, etc) and such a connection can be made utilizing a physical connection (e.g., Ethernet cable, serial cable, parallel cable, USB cable, etc).
  • [0043]
    FIG. 3 illustrates an exemplary system 300 that conveys a signal from a network command component 310 via a cell tower 320 to a cellular phone 330. The cellular phone 330 is coupled to a disabling component 340, which can limit the functionality of such a mobile device and thus, prevent an unauthorized user from accessing the memory of the device or perform unauthorized actions. The signal sent from the network command component 310 can be in the form of a caller ID which is pre-set to disable the phone as soon as the call is made and received. In another aspect of the present invention, the command can be part of the signaling protocol (e.g., IS2000, CDMA, GSM, WCDMA, etc.) employed by the mobile device to facilitate wireless communication.
  • [0044]
    Several aspects of current invention are shown that selectively limit the functionality of the cell phone. Each method shown can be selected by the user or alternatively, a desired default setting can be chosen by the user. It is to be appreciated the disabling examples given are in no way exhaustive and that a broad range of methods can be employed, including intelligence based techniques.
  • [0045]
    In this particular embodiment, the disabling component 340 is associated with four disabling systems that limit the functionality of the cellular phone 330. The methods shown represent both intrusive and non-intrusive alternatives in accordance with the subject invention. In accordance with the subject invention, an intrusive method is one that renders the device memory permanently inaccessible such as by deletion of such memory, for example. A non-intrusive technique does not permanently disable device functionality and is typically associated with a device's own security features (e.g., keypad lock, voice lock, etc).
  • [0046]
    The disabling systems shown are disable keypad 350, blank screen 360, sound audio alarm 370 and erase memory 380. The disable keypad command 350 is non-intrusive and prevents the unauthorized user from inputting commands to the mobile device 330 and thus, accessing data stored in the device. Utilizing the blank screen command 360 is similarly non-intrusive and limits functionality of the phone by inhibiting the display of command options available to the user. An alternative command is to sound an audio alarm 370 to deter an unauthorized user from accessing data and/or allowing the original device owner to easily determine the location of the device 330. An invasive alternative to the above-described commands is to erase memory 380 of the device 330, which prohibits data access by substantially all users. It is to be appreciated that the above-described embodiment can be employed in relation to substantially any mobile device as noted above.
  • [0047]
    FIGS. 4-6 illustrate document annotation methodologies 400, 500 and 600 in accordance with the present invention. For simplicity of explanation, the methodologies are depicted and described as a series of acts. It is to be understood and appreciated that the present invention is not limited by the acts illustrated and/or by the order of acts, for example acts can occur in various orders and/or concurrently, and with other acts not presented and described herein. Furthermore, not all illustrated acts may be required to implement the methodologies in accordance with the present invention. In addition, those skilled in the art will understand and appreciate that the methodologies could alternatively be represented as a series of interrelated states via a state diagram or events.
  • [0048]
    Referring initially to FIG. 4, a methodology 400 that facilitates disabling the functionality of a mobile device upon the reception of a disabling signal from an outside source. At reference numeral 410, a disabling signal is received from an outside source. In one aspect of the present invention, the signal can be sent via a network command control. Such a signal can be sent, for example, on a periodic basis or based on an event such as when the mobile device is lost or stolen. This signal can be broadcast throughout the wireless network employed by the mobile device. Alternatively, if the mobile device is outside the coverage area of the wireless network it typically employs, a third party carrier can broadcast the disable signal to insure communication with the device regardless of location.
  • [0049]
    At 420, data is extracted from the signal in order to determine if the signal contains information that relates to disabling and/or limiting the functionality of the device. For example, if the mobile device is a cellular phone and call is made to such a phone, the caller ID of the caller can be utilized to trigger the memory disabling component as mentioned above. In another example, the signal can be sent to the mobile device by way of the signaling protocol of the wireless network on which the device communicates (e.g., IS2000, CDMA, GSM, WCDMA, etc).
  • [0050]
    At 430, the functionality of the device is disabled based on the information received from the signal sent to the device. For example, if the signal relates to locking the keypad, the device keypad will lock upon reception of the signal. Alternatively or additionally, the data stored in the device memory can be transferred to another location via the wireless network. In this aspect of the current invention, once the disabling signal is received, it can contain a command to first upload desired data to a data store located on the network. Such a data store can be accessed from a plurality of disparate locations that communicate on the wireless network such as desktop computers, laptop computers, PDAs and the like.
  • [0051]
    Turning now to FIG. 5, a methodology 500 wherein the original device owner can access a lost or stolen device and subsequently limit the functionality of the device. Initially, at reference numeral 510, the original owner of the device can notify the network to disable the mobile device. The original owner can notify the network in a multitude of ways including a wireless network, the Internet or via computer, PDA or cell phone, for example. Further, a plurality of choices can be made available to the original device owner to select the type and duration of the functional limitation of the device. For example, the owner may wish to disable the screen, upload the information to a remote data store and then erase the memory. Thus, a single command can be utilized and upon completion, the network will no longer attempt to communicate with the device.
  • [0052]
    At 520, the device is located in order to ensure communication is successful with the device and/or to allow recovery of the device by the original owner. In one aspect of the present invention, a global positioning system (GPS) can be employed to provide the coordinates of the device. The GPS can function at all times or, alternatively, can function only for a desired duration of time (e.g., until the device is recovered). Choosing the type of method to locate the device can be related to the duration of time that has passed from when the device is lost or stolen to when the owner makes such a discovery. Also, choosing such a method can be related to the location (e.g., airport home, office, etc.) in which the device was lost or stolen. For example, an audio signal can be sounded to indicate the location of the device when the owner has recently lost the device. As another example, if the device has been misplaced at a residence, an audio alarm can be initiated even if the phone is off or the ringer is off.
  • [0053]
    In yet another aspect of the invention, the GPS function can be utilized when a device has been out of the possession of the owner for a substantial period of time. If the GPS locator is utilized, the device owner can track the location of the device via a network operator such as a network operator website. In this manner, the device and the data contained within the device can be recovered.
  • [0054]
    In another aspect of the invention, the device owner can notify the network their device has been lost or stolen, and such a device can be disabled upon an attempted use of the device. For example, when the current possessor (e.g., not the owner) of the device attempts to place a phone call, the network can be notified and the disabling signal can be sent to the device.

    At 530, the device functionality can be limited by utilizing invasive or non-invasive techniques as noted above. Some invasive techniques are to erase the data from the memory of the device or to permanently disable the device itself. Some non-invasive techniques are to sound an audio alarm, lock the keypad of the device or to blank the screen of the device. It is to be appreciated that numerous techniques exist and that the disabling signal can be employed in association with substantially any desired technique.
  • [0056]
    Turning now to FIG. 6, an exemplary method 600 that sends a signal and verifies such signal has been received by the device. At 610, the network operator receives a request to disable a device that communicates with the network. Such a request can be sent via phone, email, web application, disparate mobile device and the like. Further, the network operator can verify the request at 620 to insure an unscrupulous user (e.g., non-device owner) is not making the disabling request. Such verification can be made utilizing a user name and password or security question that relates to personal information (e.g., mother's maiden name, social security number, father's middle name etc), for example. Thus, by utilizing the subject invention, security measures can be implemented to insure the systems and methods are employed by authorized requestors.
  • [0057]
    At 630, a signal is broadcast to disable the device once it has been determined the user is authorized to make such a request. Such a disabling signal can be broadcast utilizing the wireless network to communicate with the device (e.g., cell phone network). Alternatively, a third party signal (e.g., satellite communication) can be employed to communicate with the device if the wireless communication is unsuccessful. Also, the signal can be sent one time, on a periodic basis or continuously until communication is successful, for example.
  • [0058]
    At reference numeral 640, the network operator can verify the device has been disabled. Such verification provides a robust, closed loop control to insure the broadcast signal successfully communicates with the device and that the device has been disabled. Such verification can be made via a signal sent back from the device (e.g., handshake, ACK/NACK or ping). The original device owner can subsequently be contacted via phone, email, etc. to provide them with such information. Further, the device owner can decide to take further action (e.g., delete the memory) if they have located the information elsewhere and no longer wish to maintain the data in the device memory. Thus, the level of disability to the device can be modified and/or changed as desired by the user.
