However, steganography is one of the most important approaches to overcome this problem. Steganography is an art and science of hiding information, the desire to send a message safely and securely as possible. Location Look-Up Table (LLUT) is designed during the embedding process, where the original bit stream of the host image is compared with the bit stream of the watermarked image if the bit stream is same it stored the message location otherwise don?t stored the location. LLUT kept the embedded information as safely as possible to maintain the quality of host image. It is robust against any foam of attack and should be perceptually invisible to HVS (Human Visual system). LLUT is design to enhance the system?s capacity in hiding information. The efficient location lookup table is design using programming language codes (MATLAB). The result is evaluated with performance measurement of PSNR (Peak Signal to Noise Ratio) and SSIM (Structural Similarity Index Measure) which are measured for all the images before attack, after JPEG (Joint Photographic Experts Group), and Wiener filter attack. The calculated evaluated results shows that the PSNR before and after JPEG attack of all the images is above 30db and SSIM before and after JPEG attack are approaching 1. This implies that the images are robust to JPEG attack, but some images results in Wiener filter manifest lack of resistance to this attack. This result signifies that some images are perceptible and robust to the attack to some extent. sof UTM 174 p.
