Research of capacity for batch steganography
批量隐写容量研究*

According to the definition of batch steganography and the properties of security,this paper presented a method to increase capacity for batch steganography.By dividing up bit-plane of large images and matrix coding,it proved that,a given image block could embed 2 bit by changing at most 1 bit in pixel,and enlarging embedding capacity.Besides analyed security of algorithm and gave embedding and extracting algorithm.The result of experiments shows that the new method of batch steganography for capacity incre...
