Steganographic Techniques of Data Hiding Using Digital Images (Review Paper)

Babloo Saha, Shuchi Sharma
2012 Defence Science Journal  
For hiding secret data in digital images, large varieties of steganographic techniques are available, some are more complex than others, and all of them have their respective pros and cons.  ...  Steganography's goal is to hide the very existence of embedded data so as not to arouse an eavesdropper's suspicion.  ...  It is based on the simple idea that the higher bit planes can also be used for embedding information. In BPCS, each block is decomposed into bit-plane.  ...
