Information security and digital watermarking with Latin squares

数字信息的重要性在不断增加。音频、视频和静态图像数据主导着我们的日常生活。这些信息具有重要的商业和战略意义。它在预防犯罪方面具有无可估量的价值：例如，来自安全摄像头的视频。保护有商业价值的材料免受盗版，保护敏感信息免受安全破坏，对我们的经济和安全至关重要。该项目通过开发新的、安全的水印和指纹来保护数字信息，从而解决了这些问题。这种水印还可以保护无线电通信信道，由于对无线连接的需求不断上升，这一点很重要。

The importance of digital information is increasing constantly. Audio, video, and still image data dominate our daily lives. Such information has commercial and strategic importance. It is invaluable in crime prevention: for example, video from security cameras. The protection of commercially valuable material against piracy and sensitive information against security breaches is vital to our economy and our safety. This project addresses these issues, by developing new, secure watermarks and fingerprints to protect digital information. Such watermarks can also protect radio communication channels, which is important due to the rising demand for wireless connectivity.
