AI Technical Summary
In existing technologies, the security of document comparison after stamping is delayed, which cannot ensure the credibility of stamped documents, and there is a risk of leakage during the process of uploading to the server.
By deploying a controller locally on the stamping machine, the electronic file and verification data of the document to be stamped are obtained. A consistency check is performed using a physical trigger signal. If they match, the scanning device is controlled to perform a local scan and verify the layout similarity and keywords. If they fail, the power to the stamping machine is physically cut off, thus achieving synchronous verification and locking.
It enables synchronous verification during the stamping process, improving the accuracy and security of verification, preventing document leakage, and has low deployment costs.
