A new approach for Steganography: Bit shifting operation of encrypted data in LSB (SED-LSB)

Bilişim Teknolojileri Dergisi, 2019
In this article, a new method is presented by adding bit shift of encrypted data in LSB method (SED-LSB). The message to be embedded in the cover image is encrypted by the key received from the user. Then, secret data are obtained by bit shifting operation using this encrypted text.
