Abstract:

Steganography is an art of hidden communication. It provides secret channel between parties intended to communicate. Least significant bit replacement is a popular steganography technique in spatial domain. It replaces the LSBs in carrier media with secret information bits. The locations for replacing LSBs are identified using DCT coefficients and difference between neighboring pixel values. The embedding and retrieval of hidden information depends on different parameters. Separate transmission of these parameters adds security to the technique. The experimental results are evaluated for different images.
