Abstract

In this paper, a new algorithm for hiding data in a binary image is introduced. This technique allows embedding data in a binary image without making any changes in the cover image; thus getting 100% similarity this technique does not need any key for embedding and extracting data. Also, it allows hiding many bits by matching values. The proposed algorithm ensures security and the hiding effect is quite invisible.
