But such a scheme is not certificated per se and is not protected by any means.
Fig. 2 is a schematic flowchart of an electronic seal authentication and authorization method according to an embodiment of the present application. Referring to fig. 2, a schematic flow chart of an electronic seal authentication and authorization method provided in the embodiment of the present application may include at least the following steps S201 to S204.
Step S201: acquiring an electronic contract file to be signed and signed, and triggering and starting an electronic seal authorization process;
step S202: extracting contract information corresponding to the electronic contract file to be signed, and generating an electronic authorization fingerprint code uniquely corresponding to the electronic contract file to be signed based on the contract information;

The embodiment of the application provides an electronic seal authentication and authorization method, in the method provided by the embodiment, an electronic contract file to be signed is obtained first, and an electronic seal authorization flow is triggered and started; extracting contract information corresponding to the electronic contract file to be signed and generating an electronic authorization fingerprint code uniquely corresponding to the electronic contract file to be signed; then, acquiring an original electronic contract seal, and generating a target electronic contract seal with an electronic authorization fingerprint code; and finally, stamping the target electronic contract seal to a seal area of the electronic contract file to be stamped to obtain the electronic contract file stamped with the electronic contract seal. According to the electronic seal authentication and authorization method, authorization information, use ways and other information of an electronic seal are combined to generate an electronic fingerprint code, and then based on an artificial intelligent image fusion technology, an original seal electronic picture is taken as a template, the fingerprint code is fused into a seal texture of the original seal picture, and a unique electronic seal picture is generated. The new electronic seal picture is basically consistent with the original picture, the difference of the seal is difficult to distinguish by naked eyes, and when the verification is needed, the system can extract the electronic fingerprint code and identify the authenticity of the electronic fingerprint code through an AI algorithm, so that the unforgeability of the electronic seal is greatly improved.
The electronic seal authentication and authorization methods mentioned in the above embodiments are described in detail below.
First, in step S201, an electronic contract document to be signed is obtained, and an electronic seal authorization procedure is triggered and started.
The contract document to be signed may be a paper version or an electronic version, and the application is not limited. If the contract document is a paper version, the paper version can be converted into an electronic version through scanning, photographing and other modes, so that an electronic seal authorization process is started to sign the contract document.
Further, after the electronic contract file to be signed is acquired, an electronic seal authorization process can be triggered and started, for example, the electronic seal authorization process in a contract approval system or an office OA system. The electronic seal authorization process in this embodiment is a process of performing electronic seal authorization on an electronic contract document to be signed, and each time an electronic seal is signed, a corresponding electronic seal authorization process is associated, so that it can be ensured that the electronic seal is not abused.
After the electronic contract file to be signed is obtained, step S202 is executed to extract contract information corresponding to the electronic contract file to be signed, so as to generate an electronic authorization fingerprint code uniquely corresponding to the electronic file to be signed.
And aiming at the electronic contract file to be signed, extracting contract information corresponding to the electronic contract file with the signature according to an electronic seal authorization flow, and generating a unique electronic authorization fingerprint code according to the contract information in the flow. That is to say, each signed electronic contract document has different corresponding contract information, and the generated electronic authorization fingerprint code is also unique, so that the uniqueness of using the electronic seal can be realized.
In an optional embodiment of the present application, the contract information corresponding to the electronic contract document to be signed includes at least one of the following: contract number, application purpose, applicant information, application time, authorizer information and authorization process number; the applicant information may include an applicant name, an applicant mobile phone number, an applicant mailbox number, and the like, and the authorizer information includes an authorizer name, an authorizer mobile phone number, an authorizer mailbox number, and the like, and specific items of the same information are not limited in the present application. Furthermore, when the electronic authorization fingerprint code is generated based on contract information corresponding to the electronic contract document to be signed, different types of information parameters contained in the contract information can be extracted and spliced according to a certain rule to generate the corresponding electronic authorization fingerprint code. For example, a character string composed of a plurality of empty fields may be preset, each field may correspond to one information type, and after acquiring the contract information, the corresponding information is added to the field corresponding to the information type. Optionally, a certain encryption mode may be adopted when the electronic authorization fingerprint code is generated, so as to further ensure the security of the electronic seal. The generated electronic authorization fingerprint code and the electronic contract file can be correspondingly stored in a fingerprint library, so that subsequent authenticity verification and query are facilitated. For example, the file identification of the electronic contract file may be stored in one-to-one correspondence with the electronic authorization fingerprint code.
After the electronic authorization fingerprint code is generated, as described in step S203, the original electronic contract stamp is obtained, and the target electronic contract stamp with the electronic authorization fingerprint code is generated by using the original electronic contract stamp as a template.
The original electronic contract stamp in this embodiment may be a stamp picture corresponding to the original electronic contract stamp stored in advance, and the stamp picture may be associated with the electronic stamp authorization flow to be called when the electronic stamp authorization flow is started. If the stamp picture is a solid stamp, the stamp picture can be converted into an electronic stamp by scanning, photographing and the like. That is to say, the stored stamp picture needs to be associated with an electronic stamp authorization process of an Office Automation (OA) system or other approval systems, so as to ensure that the electronic stamp is not misused.
And after the original electronic seal is obtained, fusing the electronic authorization fingerprint code into the seal texture of the original electronic contract seal by using the original electronic contract seal as a template and utilizing an image fusion technology.
Image fusion is the synthesis of two or more images into a new image by a specific algorithm. The technology has a basic system and mainly comprises the following contents: image preprocessing, an image fusion algorithm, image fusion evaluation and a fusion result. The hierarchy of the image fusion system is divided into: at present, most fusion algorithm researches of pixel layer fusion, feature layer fusion and decision layer are concentrated on the level. Common application scenarios include face changing in AI, long-image splicing, and the like.
According to the image fusion technology provided by the embodiment of the application, the electronic authorization fingerprint code is fused into the original electronic contract seal to form a new seal picture, the electronic seal is changed once, the authorization code in the seal picture is changed, and the new seal picture can be fused every time the electronic seal is used for printing. The picture only aims at the use stamp, can be verified and traced, and increases the counterfeiting difficulty of lawbreakers.
Meanwhile, the fused target electronic contract seal and the original electronic contract seal are stored in a warehouse for storage, the requirement that the seal is changed at one time is met, the originality of the seal is guaranteed, and the original seal form is not changed.
And finally, executing the step S204, and stamping the target electronic contract seal to the seal area of the electronic contract file to be stamped to obtain the electronic contract file stamped with the electronic contract seal.
In an optional embodiment of the present application, an electronic contract file to which an electronic contract seal is applied is obtained, a seal area for applying the electronic seal in the electronic contract file to be signed is identified first, and a target electronic contract seal is applied to the seal area of the electronic contract file to be signed; and creating a signed certificate in the seal area of the electronic contract file to be signed to obtain the electronic contract file with the electronic contract seal and the signed certificate.
The signature algorithm of the signed certificate refers to a digital signature algorithm. The digital signature is a digital string which can be generated only by a sender of the information and cannot be forged by others, and the digital string is also a valid proof of the authenticity of the information sent by the sender of the information. Digital signatures are alphanumeric strings that are processed through a one-way function to authenticate the source of the message and verify that the message has changed during transmission. The three signature algorithms that are most widely used are: rabin signature, DSS signature, RSA signature.
In practical application, when both parties of the contract use the contract, only the covered electronic contract file is used, so that the service system can be conveniently used, and the service complexity is reduced; meanwhile, the stamped electronic contract document and the seal are stored separately, so that research and development personnel can put energy in the development of the business process conveniently.
In an optional embodiment of the present application, for the electronic contract document with the electronic seal, the authenticity of the electronic contract seal stamped on the electronic contract document may also be verified.
Specifically, the electronic contract document or a contract stamping page in the electronic contract document can be obtained first to extract an electronic contract stamp corresponding to the electronic contract document; and extracting fingerprint information in the electronic contract seal through an AI algorithm, and verifying the authenticity of the electronic seal stamped in the electronic contract file based on the fingerprint information. As introduced above, the electronic contract stamp stamped in the electronic contract file is formed by fusing the electronic authorization fingerprint code and the original electronic contract stamp, so that for the electronic stamp needing authenticity verification, an AI algorithm can be used for judging whether the electronic stamp has the electronic authorization fingerprint code, if not, the electronic stamp is represented as a non-real stamp, if so, the stored electronic authorization fingerprint code corresponding to the electronic contract file can be further searched in a fingerprint library, the electronic authorization fingerprint code obtained based on the AI algorithm is compared with the electronic authorization fingerprint code stored in the fingerprint library, and if the electronic authorization fingerprint code obtained based on the AI algorithm is consistent with the electronic authorization fingerprint code stored in the fingerprint library, the electronic stamp is represented as a real stamp.
AI algorithms, i.e., artificial intelligence algorithms, are generally biased towards dealing with complex problems, such as recognition problems in video images, recognition problems in sound waveforms, natural language understanding problems, and the like, which generally require human intelligence to be able to solve. Fingerprint information in the electronic contract seal is extracted through an AI algorithm, and the authenticity of the electronic contract seal is verified through the extracted fingerprint information.
In summary, the electronic contract seal authentication and authorization process can be divided into two parts: an authentication process and an authorization process, wherein;
electronic contract seal authorization flow: uploading an original electronic contract seal picture, and associating the original electronic contract seal picture with a seal approval process, namely an electronic seal authorization process; generating a printed electronic authorization fingerprint code based on the contract information; then fusing the original electronic contract seal with the electronic authorization fingerprint code; and finally, the fused target electronic contract seal and seal authorization information are put into a fingerprint library for management.
