摘要：
Division arithmetic and generalized exploiting modification direction(DA-GEMD) method has perfect efficiency in data-hiding.However,there exist some weaknesses in DA-GEMD.Because the benchmarks are their median of nine pixels in each block of cover-image,it will give a hint for the attacker to hack the stego-image.In the paper,we utilize the Sudoku table to randomize the benchmark for each 3×3 block of cover-image.It will mix up the pixels in each image block and prevent the secret information from being extracted.The proposed method still keeps the original efficiency as DA-GEMD while promoting the security for data-hiding.
