Encrypted Secret Blend with Image Steganography for Enhanced Imperceptibility and Capacity

M. Padmaa and Y. Venkataramani
This study deals with a novel steganographic technique which demonstrates dynamic encryption based image steganographic technique in the spatial domain that hides message inside another carrier color image where the authenticated receiver can only extract this embedded secrete using the secrete key(s). This study proposed to merge the imperceptibility of pixel indicator embedding technique along with multiple key encryptions. The trap lies in encrypting the raw data into four sets of messages D1, D2, D3 and D4, say using four different keys K1, K2, K3 and K4, respectively. The encrypted messages are then embedded into cover image producing 4 stego objects. From these object, deviations of each row with respect to the cover are compared and based on minimum error, the corresponding row is selected to form the final image, thereby constructing a final image superior to its parent images. This technique also provides with suitable security owing to the fact that the concealed data cannot be deciphered until the appropriate parent key is used for the appropriate row.
