Securing LSB2 Message Steganography

Securing the confidential secret and personal messages is a vital and important task. In this paper we will show how to increase the security of LSB2 method of data steganography to protect the message embedded in digital color image. An encryption phase will be added to the hiding process, this encryption will be based on dividing the holding image into blocks and reordering the blocks to get the encrypted image, the reordering sequence here will be kept as a PK to decrypt the encrypted image.
