摘要
计算机网络技术的发展日新月异,人们从计算机科学技术的发展受益颇多,包括信息的编辑、存储和传播。但提供便利的同时,计算机网络技术也存在一定的风险,比如信息意外遭到泄露传播,被不法分子任意篡改数据或通过不法手段伪造信息,对公民的财产和隐私造成损害。数字图像处理技术的出现防止了这类问题的发生,原理就是在数据中安装隐形的标记。有了数字信号处理技术,信息分享和在加工成了便捷的操作,提供了越来越多的便利。
With the rapid development of computer network technology, people benefit from the development of computer science and technology, including the editing, storage and dissemination of information. But at the same time, there are also some risks in computer network technology, such as information leakage, illegal tampering with data, or falsifying information by illegal means, which will cause damage to citizens' property and privacy. The emergence of digital image processing technology prevents this kind of problem from happening. The principle is to install stealth markings in the data. With digital signal processing technology, information sharing and processing has become a convenient operation, providing more and more convenience.
