A deadlock free plane self-adapting routing method in a two-dimensional torus network belongs to the distributing high performance fault tolerance computing technology field, characterized in that each physical passage between nodes are divided into two virtual passages which are both two-way passages and distributed to four virtual sub network of the two-dimensional torus network; the virtual passage distribution strategy avoids the deadlock formed among the sub networks and between the sub networks and has greater self-adapting.

二维torus网络无死锁的自适应路由方法属于分布式高性能容错计算技术领域，其特征在于，把节点之间的每条物理通道被划分为两条虚拟通道，这两条通道均为两向通道，并分配到二维torus网络的四个虚拟子网中，利用虚拟通道分配策略避免了各子网内以及各子网间可能形成的死锁，同时达到更高的自适应性。

Firstly, the digital watermarking was transformed randomly, and then encrypted by chaos. The encrypted watermarking was transformed to one-dimensional row vector, and the pixel value was sorted. The coefficient of primitive image of stationary wavelet transformation was expanded to one-dimensional row vector, too, and then the sorted watermarking was embedded to the sorted low frequency and turned to two dimensions.
