Refer to the mobile terminal encryption content that Fig. 2, Fig. 2 provide for first embodiment of the invention display packing realize schematic flow sheet.The display packing that the present embodiment provides can be applicable to, in mobile terminal 10 as shown in Figure 1, mainly comprise the steps that
When step 201, unlatching encryption content, automatically start the first decryption key, it is judged that whether the first decryption key mates with preset key information, then show such as coupling and encrypt content；The head portrait needing shooting user when starting the first decryption key is decrypted.
Encryption content is generally the user meaning according to oneself, it is believed that the program of need for confidentiality, information, data etc., such as, short message, QQ chat tool, wechat, photo, preserves certain file etc. of significant data.User, when arranging, first selects to need the content of encryption, then inputs key information.The content of all encryptions can arrange an identical key information, it is also possible to is respectively provided with different key informations as required.When needs are opened, the key information only inputted is consistent with preset key information just can be opened, encryption content of otherwise not opening.
Preset key information includes various forms of password, such as, it is possible to be one, two or more the combinations such as numerical ciphers, digital alphabet mixed cipher, face information, finger print information, eyeball information.When preset key information is two or more password combination, when opening encryption content in actual use, it is possible to use two or more manner of decryption, as long as a kind of password therein correctly can open encryption content.
Step 202, otherwise, starts the second decryption key, detects whether the second decryption key mates with preset key information, then show such as coupling and encrypts content, otherwise deciphers failure.
Second decryption key is mated with preset key information, refers to both contrasts, identical.Such as, having numerical ciphers in preset key information is 123123, then the second decryption key inputted also must be 123123, just can match when both mate in mobile terminal 10, reads thus opening encryption content for user.If the second decryption key of input is 122123, then it fails to match with preset key information for the second decryption key, it is impossible to opens encryption content.
Being to be understood that and first start the first decryption key, just open the second decryption key when the first decryption key is opened unsuccessfully, this is only a kind of embodiment therein.Certainly, according to the custom of user or needs, it is also possible to select first to start the second decryption key, just open the first decryption key when the second decryption key is opened unsuccessfully, or abandon when the second decryption key is opened unsuccessfully opening.
Refer to Fig. 3, for second embodiment of the invention provide mobile terminal encryption content display packing realize schematic flow sheet.Mainly comprise the steps that
The key information that step 301, the content setting encrypted by needs are preset, preset key information includes the possessory prediction picture of mobile terminal and presetting cipher, and prediction picture and presetting cipher combine.Prediction picture and presetting cipher combine quick calling presetting cipher when can conveniently decipher be decrypted.
Preset key information includes various forms of password, such as, it is possible to be one, two or more the combinations such as numerical ciphers, digital alphabet mixed cipher, face information, finger print information, eyeball information, acoustic information.When preset key information is two or more password combination, when opening encryption content in actual use, it is possible to use two or more manner of decryption, as long as a kind of password therein correctly can open encryption content.It is, for example possible to use face information and numeral password combination, or use face information and digital alphabet mixed cipher to be combined, or eyeball information and numeral password combination, double; two or use acoustic information and numeral password combination etc. can be used.When preset image is face information, start the first decryption key when being decrypted, it is necessary to the facial image of shooting user is decrypted；When preset image is eyeball information, start the first decryption key when being decrypted, it is necessary to the eyeball image of shooting user is decrypted.
Prediction picture be user when arranging password, the head image information of the user of storage.The head portrait of storage can be a width, two width, can also be several.In the multiple portraits of storage, it is possible to be the head portrait of a people, it is also possible to be two people or the head portrait of many individuals.Or the palm of user or certain object with feature can be carried out shooting and carry out storing using as prediction picture by prediction picture.The prediction picture of storage is not done too much restriction, and user can be actually needed setting according to oneself.Presetting cipher is typically chosen numerical ciphers, and figure place is traditionally arranged to be 6 or 8.
The head image information of user and preset password are combined, the string number code of correspondence can be generated.When being decoded, can location quickly extract presetting cipher to be decoded by corresponding string number code.
When user needs to change preset key information, no matter being amendment prediction picture or amendment presetting cipher, or both revise simultaneously, the presetting cipher in memory area and corresponding string number code also all synchronize to change.
When step 302, unlatching encryption content, automatically start the first decryption key and be decrypted.Namely, when the encryption content needing to check is opened in click, system can automatic jump to the opening program of the first decryption key.When starting the first decryption key, backstage starts photographic head automatically, is continuously shot the head portrait of the user of preset quantity in preset time.In the process of shooting, if be detected that ambient light is not enough, flash lamp can be automatically turned on.Preset quantity takes natural number, and general value is 1,2,3,4,5 etc., and preset time is generally several seconds, such as, and one second, two seconds, three seconds, four seconds etc..
The head portrait of the user of the preset quantity photographed, it is possible to carry out preliminary image procossing, then mate with preset image.
Image procossing (imageprocessing) refers generally to Digital Image Processing.Digital picture refers to the big two-dimensional array obtained with equipment such as industrial camera, video camera, scanneies through shooting, and the element of this array is called pixel, and its value is called gray value.Image processing techniques generally comprises this part of compression of images, enhancing, recovery, coupling, description and identification.
Image procossing will extract some feature comprised in image or specific information, these features being extracted or information often for computer analysis image offer facility.The process extracting feature or information is the pretreatment of pattern recognition or computer vision.The feature extracted can include a lot of aspect, such as frequency domain character, gray scale or color characteristic, boundary characteristic, provincial characteristics, textural characteristics, shape facility, topological characteristic and positionality etc..The head portrait photographed and prediction picture are carried out simple image procossing by the present invention, to facilitate, two images is analyzed.
Step 303, circulation are extracted the head portrait of user and are mated with prediction picture respectively.
Concrete, extract the image information of the head portrait of the user of preset quantity respectively, general, the head portrait of user can shoot multiple.
Extract the image feature data of prediction picture.
The image information of the head portrait of multiple user being contrasted with the image feature data of prediction picture respectively, as correction data meets prerequisite, then the match is successful, and otherwise it fails to match.
The similarity that prerequisite obtains after may be configured as two image comparison is more than 95%, or more than 98%.
Step 304, judge coupling whether success.Wherein the match is successful with prediction picture for a head portrait, then the match is successful in calculation.By the coupling of multiple pictures, as long as even if having one the match is successful success, improve the success rate of the first decryption key deciphering.As the match is successful, then forward step 305 to；Otherwise forward step 307 to.
The preset key information that step 305, automatically acquisition and head image information are bound.Namely the presetting cipher in merging data it is quickly found out according to prediction picture.
Step 306, the presetting cipher transferred in key information are deciphered automatically, and deciphering terminates.From clicking encryption content to starting the first decryption key, arrive startup photographic head automatically again the head portrait of user is shot, then the photo of shooting gained is mated with prediction picture, untie password or inextricable password, altogether consuming time it is generally required to time of several seconds.
Step 307, detect whether the second decryption key mates with preset key information.When opening the second decryption key, display is manually entered the prompting frame of password.The prompting frame of input password can display at the display interface of mobile terminal, or add voice messaging point out when display.
Step 308, the password received in prompting frame, whether the password of detection input mates with preset key information.
Judge when whether the password inputted mates with the presetting cipher in preset key information, it is necessary to completely in correspondence, just thinking that the match is successful, otherwise it fails to match.Namely each figure place in the numerical ciphers inputted is required for identical with corresponding each figure place of presetting cipher.
Step 309, judge that whether successfully the password of input mate with preset key information, such as the match is successful then execution step 310；Otherwise perform step 311.
Step 310, use presetting cipher open encryption content, successful decryption.User it can be seen that encryption content.
Step 311, decipher unsuccessfully, the display interface of mobile terminal shows and deciphers unsuccessfully, or deciphered unsuccessfully by voice output.User cannot see that the content of encryption.
First, second kind of embodiment of the present invention is owing to being no longer be decrypted cipher-text information by being manually entered password every time, but first passes through automatic camera, and whether the image detecting currently used person is and the information match of the prediction picture prestored.Automatically decipher if it does, then obtain the key information with the user information binding that prestores, if it does not match, start the second decryption key, namely provide and be manually entered password window, be manually entered password deciphering.By both manner of decryption being combined, greatly facilitate user, decrease the troublesome operation every time needing input password, improve the experience of mobile terminal, also improve the safety of encryption content simultaneously.
