Method for carrying out stamp impression anti-counterfeiting processing of electronic seal by timestamp watermark

Abstract

The invention discloses a method for carrying out stamp impression anti-counterfeiting processing of an electronic seal by a timestamp watermark. The method comprises the following steps of: S1, acquiring time data of the electronic seal in a signing process; S2, acquiring impression data of the seal; S3, dividing the time data acquired in step S1 into seven groups of numbers according to year, month, day, hour, minute, second and millisecond, and randomly distributing the seven groups of numbers on a stamp impression of the electronic seal; S4, after embedding the seven groups of numbers into the stamp impression of the electronic seal, generating a watermark seal image and enabling the seven groups of numbers to be in a non-display state; S5, storing the watermark seal image obtained in step S4 in an electronic document, storing the electronic document into a seal database server, and simultaneously, by the seal database server, starting a short message or WeChat notification function to send stamp impression information of the watermark seal image to an owner of the electronic seal.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting of electronic information technology, relates to information security application technology of electronic signatures, and in particular relates to a method for anti-counterfeiting of electronic seals with time stamp watermarks. Background technique [0002] The emergence of digital multimedia and electronic files (hereinafter collectively referred to as digital information) has improved the efficiency of people's generation, use and management of information. Because the integrity and authenticity of ordinary digital information are difficult to be confirmed, this has led to the development of digital information signature technology. In order to prevent unauthorized parties from tampering or forging digital information, it is necessary to verify the authenticity of digital information signatures. In the prior art, anti-counterfeiting of seals has been carried out by using the time of...

Problems solved by technology

In the prior art, anti-counterfeiting of seals has been carried out by using the time of the signature to carry out anti-counterfeiting, such as Chinese patent application number 2008100561937 and Chinese patent application number 2013100352538, etc. The anti-counterfeiting information in technical schemes such as 2013100352538 has all collected the signature time; but these technical schemes are only for the signature The application of simple collection of seal time, and the accuracy of the collection time is limited, there is still a large room for counterfeiting seals
