Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
With the pursuit of efficiency and convenience, electronic signature technology is widely applied to various social activities. The electronic seal is a kind of security data digitally signed by the signer of the electronic seal, including the owner information of the electronic seal and the data of the graphical content, and is used for securely signing the electronic document. The electronic signature is a process of signing an electronic document by using an electronic seal, and can realize a visual effect similar to the stamping operation of a paper document, and electronic signature data comprises information such as the electronic seal, signature time, hash of original text, custom data, a signer certificate, a signature algorithm identifier, a signature value and the like.
As an expression form of the electronic signature, the electronic signature guarantees the integrity and authenticity of information and the non-repudiation of a signer, and effectively prevents the information of a signature file from being tampered; the online seal breaks through the limitation of time and space, and greatly improves the working efficiency.
For the use records of the electronic seal, the existing electronic signature system generally stores the electronic seal into a centralized database, so that the probability of tampering or losing the electronic seal is greatly increased, and the electronic seal system is not beneficial to credible supervision, audit and complete tracing. If a business person who uses the electronic seal to carry out electronic signature uses the electronic seal illegally by a printing person or the electronic seal using password is stolen by other people and then used illegally, and meanwhile, the use record in the centralized database is deleted or modified, the post audit and accountability can be influenced; if the system or the database is attacked, the data is lost or tampered, and the subsequent audit and tracing are affected; if someone forges a seal pattern to seal a file and forges a use record in a database, audit and accountability cannot be realized afterwards. Thus, usage records cannot be "truthful", causing them to lose their meaning of existence.
