“…The word steganography comes from the Greek words "stegos" which means "cover" and "grafia" means "writing" [5] [6], [7] defining it as "covered writing" or information hiding [8]. It is an art and science of writing the hidden data in such a way that no one, other than the sender and intended receiver is aware of the existence of the data [9] by covering the message existence in another medium such as audio, video, image or communication protocol. One of the steganography algorithms is the Least Significant Bit(LSB) substitution that directly replaces the LSBs of the cover image with the secret message bits.…”

The security of information during transmission in the open network is crucial. While sharing digital data on the internet, it is essential to observe information security goals: confidentiality, integrity, authenticity, and accuracy. This paper presents a multiple tier information security through image steganography technique using a novel puzzle in YCbCr color space, and digitally signed stego image for authentication. Experimental results show that the resemblance between the stego-images and cover images is high. The recognition of the stego image is small, with the use of the Human Visual System (HVS) having an average PSNR value of 47.72db. The probability of detection of the stego-images using Chi-Square Analysis is low, with the average value of 4.39E-05.
