Abstract :
This paper presents a novel Lossless Secure data embedding algorithm in which the vital information can be embedded into the cover image while preserving the quality of cover image and maintaining the security of the data to be embedded. The cover image quality and embedded data security are two main issues that need to be considered during the process of the data embedding. Our SDEM-DCT (Scramble Data Embedding in Mid-frequency range of DCT) Algorithm consists of three major security levels that can be used to hide Credit Card Numbers of many customers inside the bank LOGO.
