摘要：In this paper, an improvement in 3-3-2 approach is proposed and implemented with the purpose ofsecurity enhancement and quality maintenance. In this approach, instead of using the same method for whole message,we proposed two different techniques 2-1-1 and 1-2-1. Both are based on the LSB & MSB of red, green and blue color.These are used in combination to hide the whole byte in a single pixel. According to the results, it is observed thatsecurity is improved as compared to existing 3-3-2 approach with reasonable PSNR value.
