Whether key information matches, and shows encrypted content if matching；Need to shoot the head portrait of user when starting the first decryption key
It is decrypted.
Encrypted content is generally user according to oneself the meaning, it is believed that program, information, data of need for confidentiality etc., than
Such as, short message, QQ chat tool, wechat, photo, some file for preserving significant data etc..User is first in setting
First selection needs the content encrypted, then inputs key information.Identical key letter can be set in the content of all encryptions
Breath, also can according to need and different key informations is respectively set.When needing to open, the key information that only inputs with it is preset
Key information could unanimously open, encrypted content of otherwise not opening.
Preset key information includes various forms of passwords, for example, can be numerical ciphers, digital alphabet mixing it is close
The one kind such as code, face information, finger print information, eyeball information, two or more of combinations.When preset key information be two kinds or
When a variety of password combinations, when opening encrypted content in actual use, two or more manner of decryption can be used, as long as wherein
A kind of password correctly be openable encrypted content.
Step 202, otherwise, starts the second decryption key, the second decryption key of detection and preset key information whether
Match, show encrypted content if matching, otherwise decryption failure.
Second decryption key is matched with preset key information, refers to the two comparison, identical.For example, preset
Having numerical ciphers in key information is 123123, then the second decryption key inputted also must be 123123, and the two is mobile whole
Matching Shi Caineng is carried out in end 10 to match, and is read to open encrypted content for user.If the second decryption of input is close
Spoon is 122123, then it fails to match with preset key information for the second decryption key, cannot open encrypted content.

Referring to Fig. 3, being the realization stream of the display methods for the mobile terminal encrypted content that second embodiment of the invention provides
Journey schematic diagram.It mainly comprises the steps that
Step 301, the key information that the content setting encrypted will be needed preset, preset key information includes mobile terminal
The prediction picture and presetting cipher of the owner, prediction picture are merged with presetting cipher.By prediction picture and presetting cipher
Quick calling presetting cipher when can be convenient decryption is merged to be decrypted.
Preset key information includes various forms of passwords, for example, can be numerical ciphers, digital alphabet mixing it is close
The one kind such as code, face information, finger print information, eyeball information, acoustic information, two or more of combinations.When preset key is believed
When breath is two or more password combinations, when opening encrypted content in actual use, two or more decryption sides can be used
Formula, as long as one such password is correctly openable encrypted content.It is, for example, possible to use face informations and digital cipher code set
It closes, is perhaps combined or can be used eyeball information and numerical ciphers using face information and digital alphabet mixed cipher
Combination, double or use acoustic information and digital password combination etc..When preset image is face information, the first decryption of starting
When secret key is decrypted, the facial image for needing to shoot user is decrypted；When preset image is eyeball information, starting
When first decryption key is decrypted, the eyeball image for needing to shoot user is decrypted.
Prediction picture is user when password is arranged, the head image information of the user of storage.The head portrait of storage can be
One width, is also possible to several at two width.In the multiple portraits of storage, the head portrait of a people can be, be also possible to two people or more
Personal head portrait.Or prediction picture can be shot the palm of user or some object with feature simultaneously
It is stored using as prediction picture.Excessive limitation is not done to the prediction picture of storage, user can be according to oneself
Actual needs go to be arranged.Presetting cipher is typically chosen numerical ciphers, and digit is traditionally arranged to be 6 or 8.
The head image information of user and preset password are merged, corresponding string number code can be generated.Into
When row decoding, it cracking can be positioned by corresponding string number code and extract presetting cipher to be decoded.
When user needs to change preset key information, either modification prediction picture still modifies presetting cipher,
Or both modify simultaneously, the presetting cipher in storage region and corresponding string number code also all synchronize change.
When step 302, unlatching encrypted content, automatic first decryption key that starts is decrypted.It clicks to open and needs to look into
When the encrypted content seen, system can automatic jump to the opening program of the first decryption key.When starting the first decryption key, backstage
Automatic starting camera, is continuously shot the head portrait of the user of preset quantity in preset time.During shooting, if
It detects ambient light deficiency, flash lamp can be automatically turned on.Preset quantity takes natural number, and general value is 1,2,3,4,5 etc., in advance
Setting the time is generally several seconds, for example, one second, two seconds, three seconds, four seconds etc..
The head portrait of the user of the preset quantity taken, can carry out preliminary image procossing, then with preset image
It is matched.
Image procossing (image processing) refers generally to Digital Image Processing.Digital picture refer to industrial camera,
The equipment such as video camera, scanner pass through the big two-dimensional array that shooting obtains, and the element of the array is known as pixel, and value claims
For gray value.Image processing techniques generally comprises compression of images, enhancing, recovery, matching, description and identifies this part.
Image procossing will extract certain features or specific information included in image, these features or information for being extracted
Image often is analyzed for computer, and convenience is provided.The process of extraction feature or information is the pre- place of pattern-recognition or computer vision
Reason.The feature of extraction may include many aspects, such as frequency domain character, gray scale or color characteristic, boundary characteristic, provincial characteristics, line
Manage feature, shape feature, topological characteristic and relational structure etc..The head portrait taken and prediction picture are carried out simply in the present invention
Image procossing, two images are compared and analyzed with facilitating.
The head portrait that step 303, circulation extract user is matched with prediction picture respectively.
Specifically, the image information of the head portrait of the user of preset quantity is extracted respectively, in general, the head portrait of user can
To shoot multiple.
Extract the image feature data of prediction picture.
The image information of the head portrait of multiple users is compared with the image feature data of prediction picture respectively, it is such as right
Than data fit prerequisite, then successful match, otherwise it fails to match.
Prerequisite may be configured as the similarity obtained after two image comparisons be greater than 95%, or be greater than 98%.
Step 304 judges whether matching succeeds.Wherein a head portrait and prediction picture successful match, then calculate successful match.
By the matching of multiple pictures, as long as improving the success rate of the first decryption key decryption even if there is a successful match success.
Such as successful match, then step 305 is gone to；Otherwise step 307 is gone to.
Step 305, the automatic preset key information obtained with head image information binding.It is quickly found out according to prediction picture
Presetting cipher in merging data.
Step 306, the presetting cipher transferred in key information are decrypted automatically, and decryption terminates.From click encrypted content
The head portrait of user is shot to starting the first decryption key, then to automatic starting camera, then will be shot resulting
Photo is matched with prediction picture, unlocks password or inextricable password, in total the time-consuming time for generally requiring several seconds.
Whether step 307, the second decryption key of detection match with preset key information.When opening the second decryption key,
Display is manually entered the prompting frame of password.Input password prompting frame can be shown in the display interface of mobile terminal, or
Person is in display along with voice messaging prompts.
Whether the password in step 308, reception prompting frame, the password for detecting input match with preset key information.
When judging whether the password of input matches with the presetting cipher in preset key information, need in complete correspondence,
Just think successful match, otherwise it fails to match.Each digit in the numerical ciphers inputted requires the phase with presetting cipher
The each digit answered is identical.
Step 309 judges that the password of input matches with preset key information and whether succeeds, and step is executed if successful match
Rapid 310；It is no to then follow the steps 311.
Step 310 opens encrypted content, successful decryption using presetting cipher.User can see the content of encryption.
Step 311, decryption failure, show decryption failure, or be output by voice on the display interface of the mobile terminal
Decryption failure.User cannot see that the content of encryption.
First, second kind of embodiment of the invention is due to being no longer that ciphertext letter is decrypted by being manually entered password every time
Breath, but first passes through automatic camera, and whether the image for detecting currently used person is information phase with the prediction picture prestored
Match.It is decrypted automatically if it does, then obtaining with the key information for prestoring the binding of user's information, if it does not match, opening
Dynamic second decryption key, that is, provide and be manually entered password window, is manually entered password decryption.By by both manner of decryption phases
In conjunction with greatly facilitating user, reduce and need to input the troublesome operation of password every time, improve mobile terminal uses body
It tests, while also improving the safety of encrypted content.
