Review on Copyright protection in Data Hiding in an Image

Cryptography is where security engineering meets mathematics.The field of studyrelated to encoded information comes from Greek word for ”secret writing” is cryptography.The art and science of hiding information by embedding it in some otherdata is Steganography. The secret communication is carried through many sourceslike image, audio and video files. This technique mainly proposes data hiding by embeddingthe message of interest using geometric style of cryptographic algorithm,thus providing high security. Wavelet transform algorithms are used to perform preprocessing of images.
