Payload and quality augmentation using steganographic optimization technique based on edge detection

Information security is one of the most significant processes that must be taken into account when confidentially transferring information. This paper introduces a steganography technique using edge detection method. It focused on three basic and important aspects’ payload, quality security. Well-known detectors were used to generate as many pixels possible hide data achieve highest payload. The least bit (LSB) algorithm has been improved by extending bits embed between 2-4 in smooth sharp areas. To increase security, transaction two parties based dividing key cover image several parts agreeing type detection.The experiments achieved maximum load, for instance with fuzzy detector, at first, embedding 4 bitplanes if pixel 2 non-edge pixel, peak signal-to-noise ratio (PSNR) increased from 43.580to 45.790. At second, PSNR decreased 38.433-41.593. suggested scheme high pay load according human perception, it preserved nature original image.
