Embodiment 1
[0060] Take the user identity authentication process of the online payment system based on the mobile Internet service application of the present invention as an example.
[0061] The service provider user registers and uploads personal information through the personal information module 101 . Service provider users need to upload valid qualification certificates to confirm their eligibility for employment. Qualification certificates include one or more of ID cards, health certificates, specific industry qualification certificates and practice certificates issued by relevant units, and at least one of the certificates has the image of the staff. After the service provider user uploads the relevant qualification certificates, the human service personnel of the system will manually review the qualification certificates. After the human service personnel pass the review, issue a review instruction. The watermark generation module 205 generates a unique watermark image based on ...
Embodiment 2
[0069] Take the generation of the watermark image and the verification process of the watermark image of the online payment system based on the mobile Internet service application of the present invention as an example.
[0070] Such as figure 2 As shown, the watermark generation module 205 includes a local feature point extraction unit 205a, a watermark addition area selection unit 205b, a watermark matrix generation unit 205c and a watermark addition unit 205d. The local feature point extraction unit 205a extracts local feature points of the image to be watermarked. The watermark adding area selecting unit 205b is used for selecting the watermark adding area of the image to be watermarked according to the extracted local feature points. The watermark matrix generation unit 205c is used to generate a watermark matrix conforming to a normal distribution using the key. The watermark adding unit 205d adds a watermark to the selected watermark adding area according to the ge...
Embodiment 3
[0088] This embodiment is a further improvement on Embodiment 2, and further describes the watermark generation process and watermark verification process.
[0089] According to a preferred embodiment, the watermark image is composed of several pixels similar to the background color of the certificate image. These pixels are distributed in an irregular manner on the certificate image with the watermark image, so that no regular pattern that is easy to distinguish by human eyes will be produced. The steps of the watermark image generation method include:
[0090] Step 1: Establish a scrambling matrix for the original image, and the scrambling matrix includes positions corresponding to pixels of the original image one-to-one.
[0091] Step 2: Fill all the positions of the scrambling matrix with the result value obtained after multiplying the key by the points in the Gaussian elliptic curve domain.
[0092] Step 3: Replace the corresponding pixels in the original image with the...
