Problems solved by technology
However, the first method requires pre-agreement by the participants such as the sealer and the approver, which results in a longer preparation time for document approval and lower approval efficiency.
In the second method, the tampered content cannot be quickly discovered, resulting in a long approval time and affecting the correctness of the seal

The invention discloses a file identification method and device, a stamping method, stamping equipment and a stamping system, and relates to the field of stamps. According to the specific implementation scheme, the file identification method comprises the steps of obtaining an approval file and corresponding approval information; and dynamically generating an identification image according to theapproval information, and synthesizing the identification image and the approval file to obtain an identification file. Since the identification file contains the identification image, and the identification image is dynamically generated according to the approval information corresponding to the approval file, the generated identification image may be different if the approval information corresponding to the approval file is different. If the approval file is tampered, the content of the identification file synthesized by the identification image and the tampered approval file is changed, sothat the identification rate of the tampered content of the approval file is effectively improved. Before stamping is executed, participants such as approvers do not need to be appointed in advance for real-time approval, and the file approval efficiency is improved.
Description
technical field [0001] The application relates to the field of seals, in particular to the field of document identification. Background technique [0002] The seal is a symbol of the legitimacy and authority of a unit, directly representing its power, trust and responsibility. Now large enterprise groups, government agencies and branches are all over the country. Due to the large number of agencies and uneven management levels, and the general implementation of a unified legal person system, the unit seal is used frequently, and the risks inherent in the use of the seal Also larger. [0003] In various establishments, documents are usually signed with a seal. The document approver approves the document according to the regulations. After the approval, the sealer prints and seals the approved document. However, during the approval process, or during the time period between the approval and the signing of the seal, the documents are easily out of the scope of monitoring, re...
