Abstract

The invention relates to a digital watermarking processing system of BMP image, which belongs to the technical field of computer application. The digital watermarking processing system of BMP image is composed of a central processing module FPGA, a JTAG interface, an SDRAM memory, an Flash memory, an SD card interface and an LED indication lamp; the central processing module FPGA is composed of an NiosII processor, a digital watermarking processing module, a JTAG controller, an SDRAM controller, a three-state bridge controller, an SD card controller and a PIO controller that are connected together in conventional connection way through a data bus; the JTAG interface, the SDRAM memory, the Flash memory, the SD card interface and the LED indication lamp are connected with the JTAG controller, the SDRAM controller, the three-state bridge controller, the SD card controller and the PIO controller respectively in conventional connection way. The digital watermarking processing system of BMP image is fast for processing speed, small in volume, simple, portable and convenient to timely execute copyright protection on the obtained original image information.

Description

[0001] technical field [0002] The invention relates to a digital watermark processing system for BMP images, belonging to the technical field of computer applications. Background technique [0003] With the development of multimedia processing technology and network technology, more and more digital products are released and disseminated conveniently on the network. While multimedia and communication technologies bring convenience, they also bring some negative effects. For example, some individuals or groups illegally copy, disseminate and sell copyrighted digital products without permission, which greatly damages the interests of copyright owners and manufacturers; in addition, digital products are often used for In judicial evidence collection, it is necessary to ensure the integrity and authenticity of digital products. If criminals use technical means to tamper or forge digital content (audio, video, images, etc.), it will hinder judicial justice. Therefore, how to ...
