Abstract - Steganography is the practise of concealing information within other information in order to disguise the fact that communication is occurring. Although there are other carrier file types available, digital photographs are the most widely employed due to their prevalence online. There are several different steganography techniques available for covering up sensitive information in images and audio, some of which are more difficult than others. Each technique has its own strengths and weaknesses. Different applications can need the secret information to be completely undetectable, while others might need a sizable secret message to be concealed.

Key Words:  Image security, steganography algorithms, cryptography, Data security, video or audio content.
