With reference to the accompanying drawings, describe the present invention who as above constitutes in detail.
Fig. 3 is the block diagram that inserts the constituent apparatus of watermark in image of one embodiment of the invention.As shown in the figure, when generation comprises the watermark that hides Info, use the intrinsic information (being pseudo noise (PN:Pseudo Noise) code) of mobile communication terminal to replace key here.
Though also can utilize general Any Digit to generate key, utilize the above-mentioned storage mobile communication terminal that hides Info, to compare with the method for using the intrinsic code of mobile communication terminal to replace key, its efficient is lower.Promptly, as shown in the figure, if replace key, the intrinsic information that can distinguish mobile communication terminal itself is used as key, need not other hiding Info so and insert or extraction step, just can obtain to have inserted the mobile communication terminal intrinsic information that comprises in the image of watermark.
As mentioned above, the step of image can be by the content provider one side enforcement that image is provided originally the watermark insertion of the intrinsic information generation that utilizes mobile communication terminal.Lift a simple example, when mobile communication terminal is connected to wireless Internet and download images, because above-mentioned communication system is known the intrinsic information that connects and select the mobile communication terminal of image in advance, so before image is provided, respective image is inserted in the watermark that the mobile communication terminal intrinsic information that utilizes request to download generates, subsequently the image that inserts watermark is offered above-mentioned mobile communication terminal.That is to say that the image that has so inserted the watermark that utilizes the mobile communication terminal intrinsic information generation that will download becomes mobile communication corresponding terminal-specific image.
Fig. 4 shows that mobile communication terminal receives image that has inserted the watermark that utilizes the intrinsic code generation of set mobile communication terminal and the step of storing.In the present embodiment, utilize the mobile communication terminal intrinsic information that once used when inserting watermark, differentiate image and whether insert watermark, extraction hides Info, and utilizes above-mentioned information to judge whether to store the image that has inserted watermark.
As the above-mentioned explanation of doing, at enforcement of the present invention, for whether the image of judging the band watermark inserts watermark, only by taking the correlativity (Correlation) with mobile communication terminal intrinsic information value, whether the image that just can judge above-mentioned band watermark has with the mobile communication terminal intrinsic information value that will store is the watermark that key generates.
Just allow storage when therefore, having only image when above-mentioned band watermark to be processed into the mobile communication terminal special use (that is, inserting the watermark that utilizes mobile communication corresponding terminal intrinsic information to generate) that receives this image.Under situation in addition, make it and to store for preventing that image from usurping.
As above-mentioned situation, hide Info and also can utilize the intrinsic code of mobile communication terminal to extract, but, because the burden of mobile communication terminal strengthens, only utilize mobile communication terminal intrinsic information as key, just being enough to prevent that image from usurping and appending the blazer, is not essential therefore.
Utilize as upper type, the image that be stored in the mobile communication terminal is made mobile communication corresponding terminal-specific image, and have only special image to store, so, then can't utilize mobile communication terminal to download other mobile communication terminal special image.
Promptly, before the image that connects by wired, wireless mode and download is stored, intrinsic information with mobile communication terminal is a key value, judge whether respective image inserts watermark, have only when judge when watermark is arranged (, when utilizing corresponding intrinsic information key to insert watermark) just implement image storage, so, just can cut off by the connection between the terminal and be media transitive graph picture between terminal with computer etc.
And, if utilizing computer to duplicate from terminal has above-mentionedly inserted the image of watermark and it has been propagated on the internet, then can from the image of above-mentioned propagation, extract terminal information about the blazer, therefore illegal piracy, blazer can be searched and punish, the illegal effect of controlling of propagating of cutting off can be brought into play.
Fig. 5 is from the signal flow graph of content provider when mobile communication terminal provides image by wireless communication networks.As shown in the figure, if terminal also provides the intrinsic information (telephone number or PN code etc.) of oneself simultaneously to content provider's requested image by the base station, so, the foregoing supplier is the intrinsic code with the mobile communication corresponding terminal that the watermark that key value generates is inserted in the requested image, then the image that has inserted watermark is offered above-mentioned mobile communication terminal.Above-mentioned mobile communication terminal receives and has inserted the image of watermark, after grasping the intrinsic code value and the correlativity between the image of reception of oneself, if this result is more than set limits value, then being judged as is to utilize the intrinsic code value of oneself to insert the image of watermark, and image is stored in the storer.
Because this is to receive to have inserted the image of watermark,, can reduce system loading so whether the image of a mobile communication terminal GPRS band watermark is to utilize the watermark of the intrinsic code insertion of oneself to get final product when downloading by wireless network.
In addition, carry out before this all images storage that before image storage, can externally provide, also can only be defined in when directly being connected or enforcement when wireless network is downloaded with terminal to the analysis whether watermark is arranged.
Fig. 6 is mobile communication terminal inserts the step of watermark in image a signal flow graph.As shown in the figure, the content provider offers mobile communication terminal to the image that does not carry out any processing, and the terminal of downloading this image is that key value inserts watermark with the intrinsic information of mobile communication terminal before it is stored, and stores then.In this case, watermark can be used for staying for the illegal propagation that prevents download images the user's of download images information, also can be used for when respective image is illegally propagated, and analyzes the watermark of inserting, thereby finds out initial blazer.
But, as above implementing to insert under the situation of watermark step by mobile communication terminal, also can add a kind of function again, promptly, before not being to store, implementing watermark analysis by communication network but by the image that direct connection receives from the outside, if do not insert the watermark of self intrinsic code, then make it and to store.
As mentioned above, in the present invention, replace key, after the intrinsic code of use mobile communication terminal generates watermark, be inserted in the image, when reduction, also use the intrinsic code of mobile communication terminal, thus illegally usurping or propagating of image can be prevented, for the image of having propagated, can follow the trail of the blazer, control illegal propagation.
In sum, effect of the present invention is, after the image management method that the present invention is based on mobile communication terminal utilizes the intrinsic code of mobile communication terminal to generate watermark, be inserted in the script image, when the image of receiving belt watermark, can whether be to utilize the intrinsic code of oneself to insert the image of watermark by grasping with the correlativity of the intrinsic code of mobile communication terminal, can determine whether store, can prevent illegally usurping or propagating of image thereby have, for the image of having propagated, can follow the trail of the blazer, control the effect of illegal propagation.
Above embodiment only is used to illustrate the present invention, but not is used to limit the present invention.
