The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Referring to FIG. 1 and FIG. 2 , the fingerprint unlocking system 10 of the preferred embodiment of the present invention can be used in the electronic device 100 and used to manage access rights of the electronic device 100 . The electronic device 100 enters a locked state after a certain operation or after a certain period of inactivity, and prohibits the user from accessing the data of the electronic device 100, that is, the data of the electronic device 100 cannot be read, and the data cannot be written to the electronic device 100. The fingerprint unlocking system 10 can unlock the electronic device 100, that is, allow the user to unlock the electronic device 100 after operating through a specific fingerprint and access the data of the electronic device 100 after unlocking.

In addition, the application of the fingerprint unlocking system 10 is not limited to the present embodiment, and in other embodiments, it can be applied to other products or occasions, such as an access control system.

The fingerprint unlocking system 10 includes a fingerprint detecting unit 12, a database 14 and an unlocking module 16. The fingerprint detecting unit 12 is for sampling a fingerprint. The database 14 is configured to store an unlock password including a pre-stored fingerprint and a pre-stored fingerprint at a pre-stored location of the fingerprint detecting unit 12. The unlocking module 16 is connected to the fingerprint detecting unit 12 and the database 14 for determining whether the sampling fingerprint is a pre-stored fingerprint and whether the position of the sampling fingerprint on the fingerprint detecting unit 12 and the pre-stored fingerprint are consistent with the pre-stored position of the fingerprint detecting unit 12 and are consistent. The electronic device 100 is unlocked.

The electronic device 100 may be a portable smart terminal such as a mobile phone. In this embodiment, the electronic device 100 is a mobile phone and has a substantially rectangular shape, and has a front surface (ie, a surface facing the user in normal use) and a right side surface (ie, a side covered by a user's right hand-held finger during normal use) and a top side. (that is, the side of the user's right hand-held index finger that is easily covered when in normal use). The electronic device 100 includes a display screen 101 on a front surface. The display screen 101 is for displaying various information.

The fingerprint detecting unit 12 may be a device using optical technology or ultrasonic technology or a capacitive touch screen. In the present embodiment, the fingerprint detecting unit 12 employs a capacitive touch screen.

In the embodiment, the fingerprint detecting unit 12 includes a first sub-unit 121 disposed on the right side of the electronic device 100 and a second sub-unit 122 disposed on the top side of the electronic device 100. The fingerprints of the plurality of fingers perform an unlocking operation on different surfaces of the electronic device 100. easy to use.

That is to say, in the present embodiment, the fingerprint detecting unit 12 and the display screen 101 are independent devices. During the unlocking process, it is not necessary to activate the display screen 101, or the display screen 101 can be activated after being unlocked. In this way, on the one hand, power can be saved, and on the other hand, the screen saver information of the display screen 101 can be protected, and the level of privacy protection can be improved.

Of course, the setting of the fingerprint detecting unit 12 on the electronic device 100 is not limited to the present embodiment, and may be disposed at other positions of the electronic device 100, such as the bottom surface (ie, the surface facing away from the user in normal use), as needed. In addition, the fingerprint detecting unit 12 may also be a single device, and is not limited to the embodiment, that is, not divided into the first sub-unit 122 and the second sub-unit 124. In this case, the fingerprint detecting unit 12 can still be set separately from the display screen 101.

The fingerprint detecting unit 12 includes a plurality of keypads 123, each of which defines a location. That is to say, any position where the fingerprint falls within a keypad 123 is considered to be the same location. The shape and size of each of the keypads 123 may be the same or different. For example, in the present embodiment, the fingerprint detecting unit 12 includes six keypads 123 on the right side and three keypads 123 on the top side. The six keypads 123 on the right side are all rectangular and the same size, while the top side of the keypad 123 is also rectangular and the same size.

It can be understood that the number, shape and size setting of the keypad 123 are not limited to the embodiment, and may be determined according to requirements. For example, in other embodiments, the keypad 123 can be circular or elliptical, and the like.

There may be a physical dividing line 124 between the keypads 123. In other embodiments, the fingerprint detecting unit 12 may have The function is displayed and the dividing line 124 is displayed, that is, the dividing line 124 is a virtual line. For example, the fingerprint unlocking system 10 includes a display control module 18 coupled to the fingerprint detecting unit 12 for controlling the fingerprint detecting unit 12 to display the dividing line 124.

In addition, the fingerprint detecting unit 12 can also display the identifier 125 in each of the keypads 123 to facilitate the user to recognize the position when unlocking. For example, the nine keypads 123 in the present embodiment respectively display the numbers "1-9" to simulate password keyboard. That is to say, the display control module 18 is further configured to control the fingerprint detecting unit 12 to display the identifier 125. Of course, the identifier 125 is not limited to the number "1-9", but may be other symbols (such as Chinese characters or patterns, etc.) that can identify the keypad 123.

Of course, the dividing line 124 and the marking 125 are not limited to the embodiment, and may be omitted in other embodiments.

The database 14 may be a cloud database connected by wireless communication, or may be a storage device of the electronic device 100 (for example, a memory or a memory card of the electronic device 100), and includes one or more unlock passwords. The database 14 can be edited while in the setting mode. In the present embodiment, the fingerprint unlocking system 10 includes a setting module 19 connected to the fingerprint detecting unit 12 and the database 14 for recording the operation of the user in the fingerprint detecting unit 12 and storing it on the database 14. That is to say, the pre-stored fingerprint and the pre-stored fingerprint are stored in the database 14 as the unlock password in the pre-stored position of the fingerprint detecting unit. The setting module 19 can be activated by a specific operation, such as pressing a specific button or combination of keys of the electronic device 100.

The unlocking module 16 can be a software module running on the processor of the electronic device 100 or a separate hardware module, and has the function of unlocking the module 16 when running or starting up.

Referring to FIG. 3, in the fingerprint unlocking system 10 of another preferred embodiment of the present invention, the fingerprint detecting unit 12a and the display screen 101 can be integrated. For example, the display screen 101 uses a capacitive touch screen to sample a fingerprint through the display screen 101. In addition, in other embodiments, the fingerprint detecting unit 12a may further include a plurality of subunits, wherein the partial subunits are set independently of the display screen 101, and the partial subunits are integrated on the display screen 101. For example, in the above embodiment, in addition to the first sub-unit 122 and the second sub-unit 124, the display screen 101 also functions as a sub-unit of the fingerprint detecting unit 12 (for example, a third sub-unit).

In the present embodiment, the fingerprint detecting unit 12a may be provided with a keypad 123a, and has a dividing line 124a and an identifier 125a (for example, a numeral "1-9").

In the embodiment, the fingerprint detecting unit 12a is used for sampling fingerprints, and may also have the function of touching the display screen. The database 14 is configured to store an unlock password including a pre-stored fingerprint, a pre-stored location of the pre-stored fingerprint in the fingerprint detecting unit 12a, a pre-stored appearance order of the pre-stored fingerprint, and a pre-stored position change of the pre-stored fingerprint. The unlocking module 16 is connected to the fingerprint detecting unit 12a and the database 14 for determining whether the sampling fingerprint is a pre-stored fingerprint. The unlocking module 16 is further configured to determine, when the fingerprint is a pre-stored fingerprint, a position, an appearance order, and a position change of the sample fingerprint on the fingerprint detecting unit 12a, a pre-stored position of the pre-stored fingerprint in the fingerprint detecting unit 12a, and a pre-stored appearance order of the pre-stored fingerprint. Pre-stored fingerprints The position changes are consistent and the electronic device 100 is unlocked when it is consistent.

The fingerprint unlocking method of the preferred embodiment of the present invention can be performed by the fingerprint unlocking system 10 and includes the following steps:

S1: sampling fingerprint;

S2: determining whether the sampled fingerprint is a pre-stored fingerprint;

S3: if the sampled fingerprint is a pre-stored fingerprint, it is determined whether the position of the sampled fingerprint on the fingerprint detecting unit 12 and the pre-stored fingerprint are consistent with the pre-stored position of the fingerprint detecting unit 12;

S4: If they are consistent, the electronic device 100 is unlocked.

In this embodiment, the fingerprint unlocking method further includes the following steps:

S0: The unlock password is set and stored, and the unlock password includes a pre-stored fingerprint and a pre-stored fingerprint in the pre-stored position of the fingerprint detecting unit 12.

The step S0 can be implemented by the setting module 19, the fingerprint detecting unit 12 and the database 14. Step S1 can be implemented by fingerprint detection unit 12, and steps S2-S4 can be implemented by unlock module 16.

In this embodiment, taking the fingerprint detecting unit 12 as an example (that is, taking a capacitive touch screen as an example), step S0 includes:

S01: Turn on the setting mode;

S02: sampling is applied to the fingerprint detecting unit 12 and identifying a corresponding position; and

S03: The saved fingerprint is a pre-stored fingerprint and the corresponding location is a pre-stored location of the preset fingerprint.

In step S01, the electronic device 100 may have a specific button or key combination, and the setting module 18 may be activated and the unlocking module 16 may be turned off after being pressed. Thus, only the setting module 18 can read the user on the fingerprint detecting unit 12. Operational information. In addition, it can also be set that the setting mode can be performed only after unlocking to prevent security breaches.

Step S02 includes applying the same fingerprint to the same location (eg, keypad 123), applying a plurality of different fingerprints to a plurality of different locations (eg, different keypads 123), applying the same fingerprint to a plurality of different locations (eg, different keys) Area 123) or a plurality of different fingerprints are applied to the same location. For example, the user can place the middle finger to the same keypad 123 (for example, “3”). Thus, the fingerprint detecting unit 12 can sample the fingerprint of the middle finger and record the keypad 123 (for example, “3”), and the user can also use the little finger and the ring finger. The middle finger is placed in a plurality of different keypads 123 (e.g., "3", "6", and "9"), such that the fingerprint detecting unit 12 can sample the fingerprints and record the keypad 123 (e.g., "3", "6) "and "9"). The user can also place the middle finger on a plurality of different keypads 123 (eg, "3", "6", and "9"), such that the fingerprint detecting unit 12 can sample the middle finger fingerprint and record the keypad 123 in which it is located (eg, "3" ", "6" and "9").

After the unlock password is set, the setting mode can be turned off by pressing a specific button or key combination of the electronic device 100, that is, the setting module 18 is turned off, and the unlocking module 16 starts receiving the user input and performs an unlocking action.

In step S1, after the user operates the fingerprint detecting unit 12, the fingerprint detecting unit 12 can sample the fingerprint.

In step S2, the unlocking module 16 first compares the sampled fingerprint with the pre-stored fingerprint, and if the sampled fingerprint can be found in the pre-stored fingerprint To the pairing, proceed to step S4. If there is no pairing, the password is incorrect and the unlocking fails.

In step S3, the unlocking module 16 actually verifies whether the user's operation on the fingerprint detecting unit 12 is the same as the user's operation on the fingerprint detecting unit 12 when the unlocking password is set. This step actually unlocks the password based on the unlocking of the fingerprint, and the password is the location of the fingerprint. Only when these are consistent can the unlock be successfully completed. Therefore, if the sampling fingerprint finds a pair, the unlocking module 16 determines whether the position of the fingerprint fingerprint at the fingerprint detecting unit 12 is consistent with the position of the pre-stored fingerprint at the fingerprint detecting unit 12.

In step S4, the unlocking module 16 unlocks the electronic device 100 if the unlocking passwords are identical.

In another preferred embodiment, the fingerprint unlocking method can still be performed by the fingerprint unlocking system 10 and includes the following steps:

S1: sampling fingerprint;

S2: determining whether the sampled fingerprint is a pre-stored fingerprint;

S3: if the sampled fingerprint is a predetermined fingerprint, determine whether the position, appearance order, and position change of the sampled fingerprint on the

fingerprint detecting unit

12 or 12a and the pre-stored position of the pre-stored fingerprint in the

fingerprint detecting unit

12 or 12a, the pre-existing order of the pre-stored fingerprint, and Whether the pre-stored position of the pre-stored fingerprint changes consistently; and

S4: If they are consistent, the electronic device 100 is unlocked.

S0: setting and storing the unlocking password, including the pre-stored fingerprint, the pre-stored position of the pre-stored fingerprint in the

fingerprint detecting unit

12 or 12a, the pre-stored appearance order of the pre-stored fingerprint, and the pre-stored position change of the pre-stored fingerprint.

The step S0 can be implemented by the setting module 19, the

fingerprint detecting unit

12 or 12a and the database 14. Step S1 can be implemented by

fingerprint detecting unit

12 or 12a, and steps S2-S4 can be implemented by unlocking module 16.

In this embodiment, taking the fingerprint detecting unit 12a as an example, the step S0 includes:

S01: Turn on the setting mode;

S02: sampling a plurality of fingerprints sequentially applied to the same position of the fingerprint detecting unit 12a; and

S03: storing a plurality of fingerprints as pre-stored fingerprints, wherein the location is a pre-stored location of the preset fingerprints, and the order in which the plurality of fingerprints appear is a pre-stored appearance order of the pre-stored fingerprints, and the pre-stored position of the pre-stored fingerprints is changed to be fixed.

In step S01, the electronic device 100 may have a specific button or button combination, and the setting module 18 may be activated and the unlocking module 16 may be turned off after being pressed. Thus, only the setting module 18 can read the user on the fingerprint detecting unit 12a. Operational information. In addition, it can also be set that the setting mode can be performed only after unlocking to prevent security breaches.

In step S02, the plurality of fingerprints may have the same fingerprint or different fingerprints. Taking different fingerprints as an example, the user can sequentially place the little finger, the ring finger and the middle finger to the same keypad 123a (for example, "3"). Thus, the fingerprint detecting unit 12a can sample the fingerprints and record the keypad 123a (for example, "3" "). That is to say, multiple fingerprints are Different fingerprints (ie, the fingerprints of the little finger, the ring finger, and the middle finger), the keypad 123a (for example, "3") is in the position, and the order in which the plurality of fingerprints appear is (ie, the fingerprints of the little finger, the ring finger, and the middle finger in turn) The order in which the pre-stored fingerprints appear is that since only one of the keypads 12 (for example, "3") is present, the position of the pre-stored fingerprints is unchanged, and the positional change is fixed.

In other embodiments, the plurality of fingerprints may be the same fingerprint. For example, the user may place the middle finger multiple times to the same keypad 123a (eg, “3”). Thus, the fingerprint detecting unit 12a may sample the middle finger fingerprint and record the location. Keypad 123a (eg "3"). That is to say, the plurality of fingerprints are the same fingerprint, and the keypad 123a (for example, "3") is located at the position, and the order in which the plurality of fingerprints appear is actually the number of occurrences of the middle finger fingerprint. Thus, in order to detect the number of occurrences of the fingerprint, it is also possible to define the interval at which the fingerprint appears, for example, 1 second. In this way, the fingerprint of the middle finger can be re-detected after being separated by more than 1 second. Since it only falls on one of the keypads 12 (for example, "3"), the position of the pre-stored fingerprint does not change, and the positional change is fixed.

In step S03, taking a plurality of fingerprints as different fingerprints, that is, the fingerprints of the little finger, the ring finger, and the middle finger are recognized as stored in the pre-stored fingerprint, and the keypad 123a of the little finger, the ring finger, and the middle finger is placed (for example, 3") is stored as a pre-stored location of the preset fingerprint and stored. The order in which the fingerprints of the little finger, the ring finger and the middle finger appear in sequence is identified as the appearance order of the pre-stored fingerprint, and the position of the pre-stored fingerprint changes to be fixed. This information together constitutes the unlock password and is saved.

In step S03, taking a plurality of fingerprints as the same fingerprint as an example, that is, the fingerprint of the middle finger is recognized and stored as a pre-stored fingerprint, and the keypad 123a (for example, "3") placed by the middle finger is identified as a preset. The pre-stored position of the fingerprint is stored, and the number of times the fingerprint of the middle finger appears in sequence is identified as the order in which the pre-stored fingerprint appears, and the position of the pre-stored fingerprint changes to be fixed. This information together constitutes the unlock password and is saved.

That is to say, in the setting mode, the collected fingerprint, the collected fingerprint at the position of the

fingerprint detecting unit

12 or 12a, the order of occurrence of the collected fingerprint, and the position change of the collected fingerprint are recorded as an unlock password, and are stored in the database. 14. Thereafter, the electronic device 100 exits the setting mode, the setting module 19 is turned off, and the unlocking module 16 is activated. The

fingerprint detecting unit

12 or 12a resamples the fingerprint, the position of the fingerprint, the appearance order of the fingerprint, and the position change of the fingerprint, and the pre-stored fingerprint stored in the database 14, the pre-stored position of the pre-stored fingerprint, the pre-stored appearance order of the pre-stored fingerprint, and the pre-stored fingerprint. The pre-stored position change is compared to determine whether the device is consistent. If the user is authorized, the unlocking module 16 unlocks the electronic device 100 and allows the user to use the electronic device 100. If not, the unlocking module 16 does not unlock the electronic device. In the device 100, the user cannot operate or use the electronic device 100.

In another embodiment, taking the fingerprint detecting unit 12 as an operation object, the step S0 may include:

S01: Turn on the setting mode;

S02: sampling a plurality of different fingerprints simultaneously applied to a plurality of different positions; for example, the user can simultaneously place the little finger, the ring finger and the middle finger to three of the six keypads 123a on the right side, and the index finger is simultaneously placed on the top side. Three keypads One of 123a, in this way, the fingerprint detecting unit 12a can sample the fingerprints and record the keypad 123a in which it is located;

S03: storing a plurality of different fingerprints as pre-stored fingerprints, a pre-stored position where a plurality of different positions are preset fingerprints, and a pre-stored appearance order of the pre-stored fingerprints are simultaneously, and the pre-stored position of the pre-stored fingerprints is changed to be fixed. That is to say, the fingerprints of the little finger, the ring finger, the middle finger and the index finger are identified and stored, and the keypad 123a placed by the little finger, the ring finger, the middle finger and the index finger is identified as a pre-stored position of the preset fingerprint and stored.

In another embodiment, taking the fingerprint detecting unit 12a as an operation object, the step S0 includes:

Turn on the setting mode;

The fingerprint applied to the fingerprint detecting unit 12a and slid is sampled; for example, the user can place a finger (for example, an index finger) on the fingerprint detecting unit 12a and slide. Thus, the fingerprint detecting unit 12a can sample the fingerprint of the finger and track the change of the keypad 123a where the fingerprint is located, for example, from "1" to "2" to "3"; of course, the user can also place multiple fingers simultaneously or sequentially. The fingerprint detecting unit 12a slides, for example, the index finger slides from "1" through "2" to "3", while the middle finger slides from "4" through "5" to "6", or the index finger slides from "1" through "2" "to "3", then the middle finger slides from "4" through "5" to "6"; and

The fingerprint is saved as a pre-stored fingerprint, the location of the fingerprint is the pre-stored location of the preset fingerprint, and the appearance order of the fingerprint is the pre-stored appearance order of the pre-stored fingerprint, and the sliding trajectory of the fingerprint is the pre-stored position change of the pre-stored fingerprint.

Of course, the setting of the unlock password is not limited to the embodiment, and other embodiments may be employed.
