Transfer of secret data is an important aspect in the arena of developing technology. Privacy of data is one of the major tasks required now days. In this paper, we dealt with steganographic method using randomly generated key along with raster scan, which may include horizontal or vertical pattern, access of image pixels in order to hide a plaintext in an image. The method deployed is also suitable for long plaintext insertion in order to have no visible change in the original image. The process of scanning the image pixels strengthens the security level of the plaintext to be inserted. Optimal Pixel Adjustment Process (OPAP) is applied to the procured stegoimage in order to enhance the image quality.
