隐写术中的乘积完美Z2Z4-linear码
Product Perfect Z2Z4-linear codes in Steganography
摘要：
乘积完美码已被证明可以提高F5隐写方法的性能，而完美Z2 Z4-线性码最近被引入作为一种有效的嵌入数据的方法，符合+/-1-隐写。在本文中，我们提出了两种隐写方法。一方面，推广了乘积完美码。另一方面，这种推广适用于完美Z2 Z4-线性码。最后，所提出的方法的性能进行评估和比较与上述计划。
英文摘要：
Product perfect codes have been proven to enhance the performance of the F5 steganographic method, whereas perfect Z2Z4-linear codes have been recently introduced as an efficient way to embed data, conforming to the +/-1-steganography. In this paper, we present two steganographic methods. On the one hand, a generalization of product perfect codes is made. On the other hand, this generalization is applied to perfect Z2Z4-linear codes. Finally, the performance of the proposed methods is evaluated and compared with those of the aforementioned schemes.
