Fig. 5 is a schematic diagram showing a preferred construction of the remote authorization accounting system of the present utility model. The system includes an authorization unit 100, a remote authorization printing device 200 and a verification unit 300. When the system works, the authorization unit 100 transmits an authorization code generated based on the biological characteristics and file information of the stamp rights man to the stamp operator, and can acquire the biological characteristics of the stamp rights man and transmit the biological characteristics to the remote authorization stamp device 200; the printing operator writes the obtained authorization code above the part of the document to be stamped, and places the document with the authorization code written at the image collector 293 of the remote authorization printing device 200, the remote authorization printing device 200 can compare related information according to the collected images, stamp the document if the information is consistent, reject stamping the document if the information is inconsistent, and prompt for errors; the verification unit 300 can verify whether the stamp, the authorization code and the document information are identical to each other by acquiring the stamped stamp and the document verifier marked with the authorization code document.
Fig. 6 is a schematic diagram showing a preferred authorization unit configuration of the system for remote authorization according to the present utility model. The authorization unit 100 preferably includes a file acquisition module 101, a biometric feature acquisition and processing module 102, a second file digest extraction module 103, and an authorization code generation module 104. At the time of remote authorization, the file obtaining module 101 may obtain complete files in various formats by various modes, such as a wireless communication mode or a camera shooting mode, and convert the files into file images convenient for extracting file summaries, and transmit the file images to the file summary extracting module two 103, where the file formats include, but are not limited to, digital photos, scanned pictures, electronic documents, and paper files, and the electronic files may be further converted into printed images. The second file digest extraction module 103 processes and calculates the file image to generate a digital file digest. And then or simultaneously, the stamp rights person reads the file, confirms the authorization or terminates the authorization, and when the authorization is needed, the stamp rights person can select one of two authorization modes, namely ordinary authorization or coupling authorization for authorization. The biometric acquisition and processing module 102 then acquires biometric features of the stamp rights individual including, but not limited to, fingerprint, iris, face, voice password, etc., and calculates a biometric digest based on the authorization pattern selected by the stamp rights individual. When the seal rights man selects the common authorization, generating a common biological characteristic abstract directly according to the biological characteristic calculation of the seal rights man; when the seal rights person selects the coupling authorization mode, the file abstract and the biological characteristic data of the seal rights person are coupled together to calculate and generate the coupling biological characteristic abstract. The authorization code generation module 104 then encrypts the common/coupled biometric digest and the file digest according to a certain algorithm and encrypts the digest mixed code with a private key, outputting a common/coupled authorization code. The stamp entitlement can inform the stamp operator of the ordinary/coupled authorization code in either a public or secret way, to which the remote authorization process is completed.
From the requirement of a hardware platform, an intelligent mobile terminal device with a fingerprint input interface is preferably adopted. Without a fingerprint interface, the fingerprint may be replaced with an input user-defined feature code.
Preferably, the file acquisition module 101 may support a number of options including, but not limited to, 3G/4G or other wide area wireless communication channels provided by a telecom operator, or WiFi, bluetooth, USB, camera, etc.; the file form can be pictures, electronic documents and paper documents. When the electronic document is received, an image can be generated in the memory by using a reading module embedded in the mobile terminal equipment, and then the image is captured into the module, so that the conversion from text to picture is realized. Preferably, the biological feature collection and processing module 102 is configured to collect biological features of the stamp rights individual and generate a biological feature digest. The biological characteristics comprise one or more of fingerprint, iris, face and voice password characteristics. The biological characteristics of the stamp rights are first processed and converted into biological characteristic data. To enhance security, various features and passwords may be added to the combination.
The authorization unit 100 preferably employs an intelligent mobile terminal device with a fingerprint input interface, a mobile terminal device capable of portrait identification, or a mobile terminal device capable of inputting a user-defined feature code, such as a mobile phone only.
Preferably, the second file digest extraction module 103 regards a set of image sequences imported and confirmed by the user as a single file, and calculates the file digest.
Fig. 7 is a schematic diagram showing a preferred verification unit of the seal remote authorization and seal system according to the present utility model. The verification unit 300 is used to verify the authenticity and integrity of the document. During remote verification, a third party verifier firstly obtains a picture format or an electronic format of a file in the form of a digital photo, a scanned picture or an electronic document in a photographing or wireless communication mode through a file obtaining and preprocessing module 301, generates a file image and an authorization code image after preprocessing, and sends the file image and the authorization code image to a file abstract extracting module III 302 and an authorization code extracting module II 303 respectively; the file abstract extraction module III 302 processes the input file image, and generates a file abstract according to effective content calculation, wherein the limited content is content excluding authorization codes and seal interference; the second authorization code extraction module 303 processes the input authorization code and converts the authorization code image into a digital authorization code; then the authorization code verification module 304 decrypts the authorization code by using the public key, extracts the file digest according to the mixed algorithm, compares the file digest with the file digest obtained by the file digest extraction module III 302, and informs the user that the user passes the verification if the file digest is consistent with the file digest obtained by the file digest extraction module III, otherwise, prompts that the user does not pass the verification.
Preferably, the verification unit 300 adopts a terminal device with a camera, such as a smart phone terminal running in a software manner, and the verifier can download and install the terminal device through a network for free. The software can automatically identify the final drop of the file, and the stamp area can be manually defined by a user in a man-machine interaction mode.
Since the identification operations of the authorization unit 100 and the verification unit 300 are not required to be operated in real time, the requirements on the operation capability of the processor are low, and the existing mobile phone and the mainstream embedded processor are sufficient. In addition, the cited digital digest and digital signature algorithm are all free standards for public disclosure in the industry, and are safe and reliable without payment.
The file digest extracting modules, i.e. the first file digest extracting module, the second file digest extracting module and the third file digest extracting module, treat a group of image sequences imported and confirmed by a user as a file and calculate a file digest, and the modules exist in the authorization unit 100, the remote authorization printing device 200 and the verification unit 300, and the key characteristic of the modules is to ensure that different photos of the same file can calculate the same file digest data. Preferably, two available technical approaches exist for implementing the calculation of the same file digest time for different photos of the same file: an optical character recognition OCR technology is used to convert a file into a text through a group of operations including image preprocessing, inclination correction, layout analysis, character segmentation and character recognition, the output text can be subjected to some operations to remove and convert some spaces, punctuation, underlines and the like which are easy to identify difference contents but do not affect the meaning of the file contents, and then the text is subjected to abstract calculation. Since most of the contents of the contract file are printed, the accuracy of the mode is high at present, and the mode can meet the application under the general condition. Another more robust method is to directly operate the extracted effective content image to extract the image features by adopting an image index type technology. There are a number of well-established algorithms for robust digital digest computation of image files, such as patent 211310039144.3. The algorithm firstly carries out binarization processing on the image, and simultaneously uses the corrosion and expansion type image processing algorithm to strengthen the effective strokes in the file image; and normalizing the angle and the size of the image by adopting an inclination correction technology, and then carrying out digital abstract operation on the binary image. Such algorithms ignore pixel level differences between images and for most text patterns, the above method can effectively and robustly calculate consistent digital signatures.
Preferably, the file digest and the biometric digest may be coupled in a variety of ways, where a simple and efficient method is to combine the file digest with the biometric digest and then perform a hash operation to obtain a result as a coupled biometric digest. The merging method includes, but is not limited to, simple concatenation, interleaving according to a certain rule or bitwise operation. The coupling increases the difficulty of illegally deconstructing the authorization code, and the remote authorization printing device 200 needs to scan the file first to calculate the file digest to verify the coupled biometric digest during the coupling authorization, thereby adding a verification step.
Preferably, the common/coupled authorization code is generated by encrypting the common/coupled biometric digest and the file digest with a private key after being mixed according to a certain algorithm, and preferably, a standard digital signature algorithm can be used.
The preferred private key is for the authorization unit 100 and the remote authorization and seal device 200, and the public key is for the authentication unit 300. The generic/coupled authorization code is preferably 22-42 characters, such as 32 characters, to facilitate the transfer and/or capture of identification by the remote authorization printer 200.
The mixed coding is to arrange the file abstract and the common/coupled biological feature abstract in a mixed way according to a certain algorithm and operate, so that the difficulty of illegally decoding the authorization code can be increased, and the common authorization code and the coupled authorization code can be mixed coded to increase the difficulty of illegally decoding the authorization code.
A preferred hybrid algorithm is: the method is characterized in that partial file abstract data are adopted as algorithm parameters, then are organized together according to algorithm penetration, and only character arrangement is carried out without operation during mixed editing. The parameters may be extracted directly from the authorization code so that the remote authorization printer 200 does not need to scan the full-text calculation file digest. The following formula shows a hybrid encoding method and a hybrid encoding structure:
[<file abstract> 0~3 ] 0~3 [F(<File abstract> 0~3 ,<File abstract> 4~31 ,<Summary of biological characteristics> 0~31] )] 4~31
Wherein, "[<File abstract> 0~3 ] 0~3 "represents the first 0-3 characters of the mixed code, directly originates from the first 0-3 characters of the file abstract, and is also a parameter of the mixed coding algorithm; followed by 4-31 characters encoded in a mixed manner, as a function F<File abstract> 0~3 And calculating parameters.
While the utility model has been described in terms of the preferred embodiment, it is not intended to limit the scope of the utility model, but rather to cover all equivalent changes and modifications that can be made in accordance with the utility model as set forth in the claims and the following description.
