Such as, " opening " word that the user writes, how no matter this character of its correspondence write, and all representing this character, is the content-form in the abstract content sub-module 311 of standard handwriting; And font architecture of this character that the user write, stroke layout etc. then can be used as the content in the standard handwriting biological characteristic sub-module 312.
In described person's handwriting submodule 320 to be identified, be provided with abstract content sub-module 321 of person's handwriting to be identified and person's handwriting biological characteristic sub-module 322 to be identified, the abstract content sub-module 321 of person's handwriting to be identified wherein, it is the abstract content that can represent this input content implication of this user by the identification of the abstract content of person's handwriting to be identified is extracted, person's handwriting biological characteristic sub-module 322 to be identified wherein is the set by the biological characteristic that can represent this person's handwriting content of this user that the analysis of the hand-written biological characteristic of person's handwriting content to be identified is extracted.
Such as, the person's handwriting content that the user imported " is opened " word, before identification, just belongs to the content in the person's handwriting submodule 320 to be identified; After handling by analysis, resulting abstract content " is opened " word etc., then can be regarded as the content in the abstract content sub-module 321 of person's handwriting to be identified; And the concrete feature of the person's handwriting that is analyzed before obtaining identification, then is considered as the content in the person's handwriting biological characteristic sub-module 322 to be identified.
Differentiate in the submodule 330 at described person's handwriting, be provided with the abstract content of person's handwriting and differentiate sub-module 331 and person's handwriting biological characteristic discriminating sub-module 332, the abstract content of person's handwriting is wherein differentiated sub-module 331, in order to the difference between abstract content sub-module 321 of more described person's handwriting to be identified and the abstract content sub-module 311 of standard handwriting, person's handwriting biological characteristic is wherein differentiated sub-module 332, in order to the difference between more described person's handwriting biological characteristic sub-module 322 to be identified and the standard handwriting biological characteristic sub-module 312.
Certainly, when comparing, can the step-up error threshold value,, under the situation within the threshold value, then be considered as identification and pass through in error degree; Under situation about exceeding outside the threshold value, then be considered as identification and do not pass through.
The various terminal forms that can carry out data storage are made a general reference, for example and without limitation in document handwriting encryption and decryption application terminal 100 described in the invention, can comprise following terminal type: mobile phone, computer, camera, player, personal digital assistant, one or more in the movable storage device.
Ginseng Fig. 2-shown in Figure 5, terminal form wherein is a computer, comprises notebook computer 101 and desktop computer 102; Join shown in Figure 6ly, terminal form wherein is a mobile phone 103, utilizes touch-screen 210 to carry out the person's handwriting input in the present embodiment; Join shown in Figure 7ly, terminal form camera 104 wherein also utilizes touch-screen 210 to carry out person's handwriting input in the present embodiment.
As further instruction, the embodiment in the aforesaid handwriting recognition module 300 is for example and without limitation, if can person's handwriting more to be identified effectively and standard handwriting between difference, that's all.
The present invention has also described a kind of document handwriting encipher-decipher method, is applied in the document handwriting encryption and decryption application terminal 100 as previously described, and this method includes following steps:
Step 1, the user need to select the document of encryption.
Such as, the document can be the text document of a word form, also can be the photo document of jpeg format, the perhaps video documents of RM form, or the like, can be as document to be encrypted.
Step 2, the user utilizes handwriting inputting structure 200 and the person's handwriting encrypting module 130 with the supporting setting of described terminal, adopt directly the mode of input person's handwriting that the selected document of previous step is encrypted, or utilize in the handwriting recognition module 300 in this terminal 310 pairs of selected documents of previous step of existing standard person's handwriting submodule to encrypt.
In this step, data document setup cryptographic algorithm then, is utilized this cryptographic algorithm to treat the rearrangement that encrypted document is carried out data, thereby is reached the purpose of encryption.And the selection mode or the content of the algorithm that should encrypt are then corresponding with user's standard handwriting.
Step 3, the user utilizes handwriting inputting structure 200 and the handwriting recognition module 300 with the supporting setting of described terminal, and importing the person's handwriting content and carrying out with the document deciphering is the person's handwriting identification of purpose.
In this step, utilize handwriting inputting structure 200 to note after user's the person's handwriting, just can utilize handwriting recognition module 300 to carry out person's handwriting and discern.
In described step 3, recognition threshold adjusting module 410 can supportingly be set, comprising the abstract content discrimination threshold of person's handwriting sub-module 411, and person's handwriting biological characteristic discrimination threshold sub-module 412, by adjusting recognition threshold, can adjust the difficulty or ease coefficient that carries out person's handwriting identification.
Step 4, person's handwriting identification document deciphering module 400 is judged the authority of user's opening document according to the recognition result of previous step, and separates the corresponding contents of confidential document according to this authority.
Such as, after user's person's handwriting identification is passed through, get final product opening document, otherwise just do not open.
Then, the user has operated document content according to permissions.
If discern under the unsanctioned situation, can also turn back in the step 3, proceed person's handwriting input and identification.
In addition, in described step 3 or step 4,, so, can obtain the authority permission by the password that input sets in advance if the handwriting information that validated user is imported can't be discerned.This is a kind of completeness set-up mode of identification.
Join shown in Figure 8ly, in described step 3 or step 4, discern frequency threshold value greater than person's handwriting if the user discerns the number of times of trial continuously, can be taken as natural number 5 such as threshold value N, when the number of times of User Recognition surpassed 5 times, system will refuse to attempt end operation.
Be less than or equal to frequency threshold value if the user discerns the number of times of trial continuously, just can be transferred to step 3, discern trial again.
Further, in described step 3 or step 4, only in the words of identification interlude more than or equal to time threshold, just can be transferred to step 3, proceed identification and attempt, if identification is at interval less than time threshold T, then can not continue to attempt end operation.Such as, the current identification of user is not all passed through for 5 times, and so, can get time threshold T is 24 hours, then need be after 24 hours, the user just allows to carry out once more person's handwriting identification.
More than be the description of this invention and non-limiting, based on other embodiment of inventive concept, all among protection scope of the present invention.
