摘要
针对监控系统中存在的认证和安全性问题,提出一种基于水印的数字监控方案,介绍了应用于此系统的数字水印算法并实现基于ARM的硬件监控平台,在此基础上完成了视频采集和水印嵌入。测试结果证明设计方案完全可行,具有较好的实用价值。
Aiming at the problem of authentication and security in the monitor system, a project of the digital monitor based on watermark is presented. A digital watermarking algorithm in the system is introduced, and the hardware platform based on ARM is implemented. Then, video collection and watermark embedding are completed. The design is proved feasible and applicable by the experimental results.
