Digital content is now posing formidable challenges to
content developers, aggregators, distributors and users.
The destruction, extraction or modification of the
embedded message is required to develop more robust

Cryptography was created as a technique for securing the
secrecy of communication and many different methods
have been developed to encrypt and decrypt data in order

message secret. The technique used to implement this, is
called steganography.
