A Fast Hiding Technology for Multiple Digital Image Based on Chaos Sequences Iterative Blending
Yonghong Zhang · 2007
An algorithm of multiple digital image information hiding is presented.Based on chaos sequences,multiple digital images can be hidden into another by using iterative blending.With the help of Logistic chaos dynamics systematic process which is non-period,non-convergence and sensitivity to the initial conditions,the real chaos sequence is produced,being the blending factor of the hiding algorithm,which improves the security of the hiding algorithm.In order to improve the security of image hiding,the hided image should be dealt with scrambling based on pixel space.The numerical experimentations show that the hiding algorithm is efficient and safety.
