The present invention provides a kind of method for preventing fingerprint from leaking, and reference picture 3, Fig. 3 prevents the side that fingerprint is leaked for the present invention The schematic flow sheet of method first embodiment.
In the present embodiment, this prevents the method that fingerprint is leaked from including：
Step S1000, judges in pending picture with the presence or absence of the finger print information with preset fingerprint information matches；
In the present embodiment, when user selects to issue or sent to a certain photo, then the photo is pending picture；And After judge in pending picture whether to include finger print information, such as pending picture includes finger print information, then extracts pending figure Finger print information in piece, and judge whether the finger print information reaches certain matching degree with preset fingerprint information.Wherein, preset Finger print information can be by personal set, or detected number of times reaches the finger print information of default frequency threshold value；When waiting to locate When the finger print information that reason picture includes and the matching degree of preset fingerprint information are more than default matching degree, then it represents that success Match somebody with somebody, i.e., there is the finger print information with preset fingerprint information matches in pending picture.
For example, a certain user have taken a personal photo, when the user selects issue or sends the photo, it is determined that The photo is pending picture.If include some finger of the user in this photo, and the fingerprint letter on the finger Breath can be detected clearly.Now, corresponding is done to the preset fingerprint information in user mobile phone to the finger print information in the photo Matching degree detection, when detection matching degree be more than default matching degree when, it is necessary to be prevented the finger print information in the photo Leakage is handled, to prevent the finger print information from leaking.
Before step S1000, user can also the typing finger print information to be protected in used equipment in advance. For example, if user does not shift to an earlier date typing finger print information to be protected on its handset, mobile phone can be a certain by detecting The number of times that finger print information accordingly occurs；When the number of times that mobile phone detects a certain finger print information appearance is more than the number of times threshold set before this During value, this finger print information can be updated to protected object, that is, be updated to preset fingerprint information.Specifically, as user exists When carrying out unlocked by fingerprint or fingerprint payment with certain finger print for the first time, equipment used in user just can record lower this and refer to Line；When user second is using the unlocked by fingerprint, then update the access times of the fingerprint, when then there is the finger print information according to It is secondary to update the number of times that the finger print information is detected.The fingerprint the number of times being detected more than default frequency threshold value When, the finger print information is updated for preset fingerprint information.
In the present embodiment, by carrying out matching degree detection to finger print information in pending picture and preset fingerprint information, The picture for meeting the condition that can carry out anti-leak processing can be filtered out, to reduce the workload to pending picture processing.
Step S2000, when there is the finger print information of the presupposed information matching in the pending picture, obtains described The pixel value of finger print information；
The finger print information of many different fingers, wherein one or more fingerprints may generally be included in pending picture Information is the finger print information matched with default finger print information；Or, the finger print information included by pending picture is not It is complete, has only included the finger print information of a certain finger part, the finger print information of the part is and preset fingerprint information matches Finger print information.Therefore, for a pending picture for including finger print information, it is necessary to the fingerprint in this pending picture Information is judged.There is the finger print information with preset fingerprint information matches in pending picture, refer in pending picture The matching degree of finger print information and default finger print information reaches default matching threshold.
