Towards robust steganography using T-codes

Steganography is the art of hiding messages within some cover media. The word steganography derives from Greek, and literally means covered writing. Messages can be hidden in any media. Typical media include digital images, sound, and video. Unfortunately, the hidden message is not resistant to media operations. For example, cropping an image that has a hidden message can result in corrupting the entire message beyond recognition. This paper proposes a scheme that permits hidden messages to withstand some simple media operations.
