Another steganographic LSB-based function

Nowadays, because of using computers and data communications become a part of our daily life, information security is a widely debated subject and extensively researched. Data hiding is an old concern that has different goals. People can embed important information and data into files, then store them on a machine on sight or hidden and encrypted. Steganography is one method to help us hiding information in files. This paper provides an overview of some steganographic methods using DCT transform, LSB technique and one-time pad keys. We also present test results obtained on color JPEG files.
