Video Steganography: Data Hiding Technique Using DCT, LSB, AES Algorithm

Steganography is the practice of concealing information within other information in order to disguise the actual act of transmission. There are a variety of carrier file types. Frequently utilized, but due to their prevalence on the web, digital photos are the most well-liked. There are a wide variety of steganography techniques available for concealing sensitive information in video frames, some of which are more sophisticated than others and each of which has unique strength sand weaknesses. In recent decades, steganography has gained momentum due to its ability to communicate data covertly. Steganography embeds secret data into cover medium that are of many forms like text, image audio and video. Video steganography is drawing more impulse due to its scope of masking larger amount of secret information. This paper provides an overall view about the embedding and encryption techniques considering video as cover.
