中文说明：数字水印技术已引起广泛关注的多媒体数据的版权保护。本文提出了一种新数字水印系统的数字图像离散余弦变（DCT） 中使用高效系统的线性分组码 （SLBC）域。拟议的数字水印系统使用 SLBC 生成的代码序列 {0，1} 提供纠错功能，然后将它替换为一个二值水印序列 {-1，1}。这实现了更强健的不可见图像水印和需要较小的存储单元为二进制序列号。生成的水印序列然后用作我们提出的数字水印系统组成的水印嵌入和水印检测过程的输入。实验结果表明，可见水印的嵌入与拟议的制度是非常强劲的反对各种高斯白噪声、 JPEG 压缩、 中位数和均值滤波，通过展示相似度值等各种攻击
English Description：
Digital watermarking has drawn extensive attention for copyright protection of multimedia data. This paper proposes a newwatermarking system for digital images using efficient systematic linear block codes (SLBC) in discrete cosine transform (DCT)domain. The proposed watermarking system using SLBC generates a code sequence of {0, 1} that provides error correctioncapabilities and then replaces it with a binary watermark sequence of {-1, 1}. This achieves more robust invisible imagewatermarks and requires a small storage unit for binary sequence numbers. The generated watermark sequence is then used as aninput for our proposed watermarking system which consists of watermark embedding process and watermark detection process.Experimental results indicate that the invisible watermark embedded with the proposed system are very robust against variouskinds of attacks such as white Gaussian noise, JPEG compression, median,
