Binary Image Hiding Algorithm Based on Multi-secret Sharing and DCT
Cao Ru-bing · 2011
A new binary image hiding scheme was proposed,which hided a binary image into several cover images.Based on the characteristics of the binary image whose value is 0 or 1,this scheme combined multi-secret sharing with RLE algorithm and DCT algorithm for the first time.According to the biggest size of cover images,this scheme divided RLE length of the shadow image into the n blocks,and then embedded the n blocks of secret information in cover images under the control of n keys.Experiment demonstrates that this scheme sufficiently increases the security of secret information and improves the robustness and acheves the better recovery effect.
