Embodiment Construction

[0037] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0038] The present invention proposes a method for embedding and authenticating personalized information of an electronic certificate for a mobile device, comprising the following steps:

[0039] Step S10, encoding the electronic certificate image and the personalized watermark image; in order to effectively embed the watermark information for anti-counterfeiting authentication without affecting the visual perception, it is necessary to convert the electronic certificate image to a specific frequency domain for watermark embedding; at the same time , in order to further strengthen the protection function of the watermark information, encode the decomposed watermark information according to the preset encoding rules; the specific steps are as follows;

[0040] Step S101, the background management system performs discrete wavelet transform on the electronic certi...

Abstract

The present invention provides a method for embedding and authenticating personalized information of an electronic certificate for a mobile device, comprising the following steps: step S10, encoding an image of an electronic certificate and a personalized watermark image; step S20, embedding the watermark and generating a personalized watermark The electronic certificate image is sent to the user's mobile device; step S30, the electronic certificate image to be detected on the user's mobile device is obtained and decoded, and the personalized watermark image is regenerated, and identification and authentication are performed. The present invention can effectively embed personalized watermark information without changing the overall visual recognition of the electronic certificate image, and complete watermark extraction and authentication through mobile devices.

Description

technical field [0001] The invention relates to the technical fields of image processing and digital security, in particular to a method for embedding and authenticating personalized information of electronic certificates for mobile devices. Background technique [0002] With the rapid development of science and technology today, mobile devices (mobile phones, tablet computers, etc.) have been widely used. The era of mobile Internet has come. Various digital information applications have entered people's daily life and brought us great convenience. . It is against this background that the electronic certificates that have appeared recently have also attracted widespread attention. The so-called electronic certificates are represented by concepts such as electronic ID cards, electronic driver's licenses, and electronic social security cards, and are stored on mobile devices. Electronic documents are easy to carry, but the value behind them goes beyond that. Having an "elec...
