Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but the present invention is not limited thereto.
An enterprise electronic seal management method based on enterprise chain codes refers to an enterprise chain code account user in a system, after the user login is authenticated by face recognition real name, a legal person verifies the login to obtain enterprise information, electronic signature operation is carried out on an electronic information file needing to be stamped according to a current available electronic seal of an enterprise, and authenticity and integrity of electronic information and non-repudiation of a signer are guaranteed.
The electronic seal has the basic characteristics that:
firstly, new concepts such as certificates and CA are not involved in the whole using process, and the electronic signature technology is completely hidden behind the electronic seal, so that people can use the electronic seal by relying on daily experience without learning and understanding the arduous technologies and concepts additionally.
And secondly, ensuring that the seal becomes an effective expression form of the signature. That is, the seal is normally displayed only when the electronic signature technology is used to verify that a certain electronic document is true and valid. Therefore, text data needs to be protected by an electronic signature technology, and a seal needs to be protected, so that the phenomenon that a legal seal is displayed on an illegal electronic file after being embezzled by a lawbreaker is avoided, and the confusion is not.
And thirdly, one physical seal can only correspond to one electronic seal. On one hand, the seal box accords with the daily use habit of people, on the other hand, leaders know that a plurality of seals are required to be managed according to daily experience, and the situation that the seal out of control flies all day is avoided.
And fourthly, the electronic seal must be stored on a removable medium (such as a USB flash disk). The removable medium storing the electronic seal is equivalent to a physical seal and can be kept as the physical seal is kept. Even a common office worker who cannot know the technical problem at once can lock the seal in the safe as before, take the corresponding seal out of the cabinet for use after seeing a leader's approval and signature, and put the seal back after the seal is used up. The mobile media must be subject to a national crypto authority audit.
Fifth, in order to make the electronic document with the electronic seal have the same appearance and other characteristics as the paper document, it is necessary to adopt the digital paper technology (CEB technology, CEBX technology, PDF technology, or SEP technology). The digital paper technology is a technical platform which is built by using the digital technology and accords with the characteristics of traditional paper, not only has strong layout description capacity, but also can be represented by drawing on paper no matter how complex the layout is, and more importantly, has layout consistency, non-tamper-ability and non-separability. For example, although the Word is very powerful, the Word can not be guaranteed, sometimes a 100-page Word document is sent to others, the other party becomes 101 pages when receiving the Word document, although the content is unchanged, the typesetting position of characters, graphics and the like is changed. The inseparability is more useful, it ensures that anyone cannot separate the seal from the document after sealing, and then seal to another document. Digital paper technology is an important foundation for electronic seal technology.
The electronic seal using process comprises the following steps:
1. the electronic seal is applied by using the organization (or individual) of the electronic seal to firstly apply for the electronic seal to an electronic seal (management) center (platform), under the condition of fulfilling normal procedures and confirming no error and legality, the electronic seal is made for an applicant, and the made electronic seal is guided into a specific storage medium, such as a USB-Key or an IC card, and submitted to the applicant.
2. Electronic seal client system
The electronic seal product provider provides an electronic seal for a user, and also provides a set of electronic seal client systems. The system should be installed in a terminal computer used by the custodian of the electronic seal. The electronic seal client system is mainly used for stamping, checking and electronic seal management and other functions.
3. Use of electronic seal
The electronic seal is used in the same way as a traditional seal. As described above, there is a need for a dedicated electronic seal client system, which is provided by an electronic seal management platform (electronic seal center) and installed on a specific computer terminal. The next steps are generally:
(1) get approval about the leader of the supervisor.
(2) And inserting an entity (such as USBKey) with the electronic seal into a USB interface of the computer terminal.
(3) And starting an electronic seal client system.
(4) And reading the electronic document needing to be stamped with the electronic seal.
(5) And clicking a 'stamping' function button on a menu at a place where an electronic seal needs to be stamped in the electronic document.
(6) The system prompts to input the pin code of the seal entity.
(7) And inputting the correct pin code used by the electronic seal, and then the document is covered with the electronic seal.
4. Verification of electronic seal
When the electronic document with the electronic seal is verified, a terminal computer provided with an electronic seal client system is also needed. When the electronic document with the electronic seal is opened, the electronic seal client system can automatically verify whether the electronic seal of the electronic document is effective. If the electronic document is modified without authorization or the electronic seal is copied and pasted on the current electronic document, the electronic seal client system can find and immediately warn the user that the electronic document is modified or the electronic document is stamped with an invalid electronic seal, and the electronic seal cannot be normally displayed, so that the aims of protecting the integrity of the electronic document and verifying that the electronic seal and the specific electronic document are related are fulfilled.
5. Loss of electronic seal
If the electronic seal is lost, the electronic seal platform (center) should be immediately lost, and the process is basically similar to the certificate revocation processing mode.
And (3) accessing the electronic seal, as shown in figure 1.
The specific use flow of the electronic seal is shown in fig. 2.
When the electronic seal is used, the electronic seal needs to be registered and logged in by a legal person first, after the electronic seal is opened and enters an enterprise chain code identity platform, the electronic seal module is logged in, the electronic seal which is successfully applied by the current enterprise can be checked, when the electronic information needs to be signed, the electronic seal which is successfully applied can be signed for the electronic information, and authenticity and integrity of the electronic information are guaranteed, and non-repudiation of the signer is realized.
The process of using the electronic seal for the first time comprises the following steps:
as shown in fig. 3, the enterprise electronic seal management method based on the enterprise chain code includes the following processes: the application system sends an application request to the credible authentication platform, the credible authentication platform acquires the seal information from the government block chain, the serial number of the applied service is returned to the application system, the government block chain inquires the service data of the applied seal according to the serial number, and the credible service provider makes a seal and completes an intelligent contract to store the seal information on the government block chain; after the application system sends a request for inquiring the application condition to the trusted authentication platform, the trusted authentication platform acquires the seal information from the administration block chain and returns the application condition to the citation system, and the user can obtain the seal.
As shown in fig. 4, the process of applying for the electronic signature of the enterprise electronic seal management method based on the enterprise chain code is as follows: the application system sends a request for applying electronic signature transaction to the trusted authentication platform, and the trusted authentication platform uploads the request to a government affair block chain and returns a transaction serial number to the citation system; after the user confirms or authorizes the transaction after passing identity authentication, the trusted authentication platform can upload the updated transaction intention information to the government affair block chain and return a confirmation or authorization result to the user, and then the trusted service provider obtains a confirmed or authorized transaction record in the government affair block chain; the trusted service provider signs the transaction records, submits the signature information to the government affair block chain, and the trusted authentication platform acquires the transaction results on the government affair block chain, combines the transaction results and signs the transaction results into a PDF file; the application system can inquire the transaction result, and the credible authentication platform acquires the transaction result on the government affair block chain and returns the transaction result to the application system; and finally, the application system can acquire the signed PDF file through the trusted authentication platform.
