A method and device for safely generating an application copy of an electronic certificate

Abstract

The invention discloses a secure generation method and device of an electronic certificate application copy. The secure generation method of the electronic certificate application copy comprises the following steps: overlaying the certificate application content information on the face of the electronic certificate to form a visual copy of the electronic certificate application copy; storing the corresponding non face region information on the non face information region of the certificate application copy according to the classes; and performing classifying signature and encryption on the visual copy of the application copy and the non face region information. By means of the secure generation method of the electronic certificate application copy, the generation of the electronic certificate application copy can be realized safely, reliably and practically in different industries and different scenarios, and the application example and the comprehensive promotion of the electronic certificates in different industries and different application scenarios can be further promoted.

Description

technical field [0001] The invention relates to information security technology, in particular to the security technology of electronic certificates. Background technique [0002] At present, at the national level, the electronic license library is defined as a type of basic library. With the demonstration application and vigorous promotion of electronic licenses in various industries, the application security of electronic licenses has received more and more attention, and has also attracted more and more attention. However, in the actual business application process, considering the uniqueness, legal effect and security of the original, the certificate holder is often based on the application copy. [0003] Therefore, the authenticity, safety, reliability and practicability of the application copy of its certificate are particularly important, and will further affect the promotion of the industry. [0004] For the production technology of the application copy of the licen...

Problems solved by technology

[0009] On the one hand, the lack of two-way digital signature mechanism protection, its authenticity and reliability cannot be protected;

[0010] On the other hand, the application information that contains privacy in the copy in the actual application scenario lacks encryption protection as the user's identity, and its confidentiality and security cannot be protected; at the same time, it lacks authorized access control to the application copy, that is, the scope of use, Control of intended use and expiry date, creating a risk of abuse;

[0011] On the other hand, there is no classified storage of license source data, expansibility information and application copy area information in the license application copy, and its practicality is not strong;

[0012] On the other hand, the original document type of the certificate does not support the generation of copies of the certificate of various file types, which is not practical enough
