Information Security is a major concern in today's modern era. Almost all thecommunicating bodies want the security, confidentiality and integrity of theirpersonal data. But this security goal cannot be achieved easily when we areusing an open network like Internet. Steganography provides one of the bestsolutions to this problem. This paper represents a new Cyclic Steganographic Technique (CST) based on Least Significant Bit (LSB) for true color (RGB)images. The proposed method hides the secret data in the LSBs of cover imagepixels in a randomized cyclic manner. The proposed technique is evaluated usingboth subjective and objective analysis using histograms changeability, PeakSignal-to-Noise Ratio (PSNR) and Mean Square Error (MSE). Experimentally it isfound that the proposed method gives promising results in terms of security,imperceptibility and robustness as compared to some existent methods andvindicates this new algorithm.
