Based on the analysis of the symbolic substitutionalgorithm, an optoelectronic hybrid computer (OEHCBSS) architecture which is based on the algorithm is proposed.
The algorithm names are signed to resist attacks based on the substitution of a weaker algorithm.
为算法名签名以抵抗攻击,该攻击是基于置换成效率更低的算法。

The watermark is compressed and the watermark is embedded in part of the pixels of the original image, then the watermark-hiding algorithm based on information substitution can be realized.
