PRIS: Image processing tool for dealing with criminal cases using steganography technique

Hiding data inside an image is a practical way of hiding secret information from intruders. Image processing can then be used to get the data back from the image. In this paper, we propose a new algorithm to hide data inside an image using the steganography technique. The original data can also be retrieved from the image using the same approach. By applying the proposed algorithm, a system called Police Report Imaging System (PRIS) is developed. PRIS is developed to handle secret information for criminal cases. The system is then tested to see the viability of the proposed algorithm. The PSNR (Peak signal-to-noise ratio) is also captured for each of the images tested. Based on the PSNR value of each image, the stego image has a higher PSNR value. Hence this new steganography algorithm is very efficient to hide data inside an image to handle information for the criminal cases.
