Electronic signature anti-counterfeiting device based on invisible watermark and signature making and identifying method thereof

Abstract

The invention discloses an electronic signature anti-counterfeiting device based on an invisible watermark and a seal making and identifying method thereof. The electronic signature anti-counterfeiting device mainly comprises an invisible watermark module and an electronic signature module and is further provided with a signature identification module, 32-bit binary code streams are adopted in theinvisible watermark technology, different color blocks are used for representing binary information bits, and the invisible watermark selects weak-intensity color blocks and cannot be identified by naked eyes. The seal making method comprises the steps of sending a request, making a strategy, previewing the synthesis of an electronic seal and an invisible watermark, stamping a new electronic sealand sending the electronic seal back to a user. The identification method comprises the steps of signature feature information extraction, invisible watermark analysis and identification report issuing. By combining the invisible watermark module, the electronic signature module and the signature identification module, the anti-counterfeiting capability of the electronic signature is improved, the use path of the electronic signature can be traced back through the information of the invisible watermark, and then the invisible watermark is analyzed by adopting an image processing technology soas to judge whether the signature is counterfeited or not.

Description

technical field [0001] The invention belongs to the field of electronic information, and in particular relates to an electronic signature anti-counterfeiting device based on an invisible watermark and a seal making and identification method thereof. Background technique [0002] Electronic signature is a form of expression of electronic signature. It uses image processing technology to convert electronic signature operation into the same visual effect as paper document sealing operation. At the same time, electronic signature technology is used to ensure the authenticity and integrity of electronic information and Non-repudiation of the signer. [0003] Electronic signatures, like the digital certificates we use, are used as a means of identity verification. They generally refer to all electronic documents that exist in electronic form, attached to electronic documents and logically associated with them, and can be used to identify the identity of the signer of the electroni...

Problems solved by technology

However, due to the advanced image processing technology now, it is easy to forge a new electronic signature through image processing or PS, which causes losses and unnecessary troubles to enterprises and their customers

At present, there is no particularly good method for anti-counterfeiting of electronic signatures. The main method is to do some management on the use process, track the use records, and record the signature documents in specific places to achieve anti-counterfeiting technology.
