High Capacity Image Steganography using Secret Key for Medical Information


The skill of thrashing the information and storing in an invisible form is referred as Steganography. The study targets to characterize the better security using RGB for image imparting. The proposed steganography algorithm uses Hybrid SPIHT DEFLATE algorithm to reduce the number of bits and increase the capacity of the thrashed information. An intense layer of RGB channel is selected for adding the compressed information. Concurrently, the position value is calculated on the specified secret key. The cover image is pixelizedon the specific channel environment and thrashed information. The proposed approach is screened on the Brain medical image. Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE) are the performance metrics evaluated in the proposed approach. The results prove that the thrashing of data in an intense layer renders minimized vulnerability over unintentional attacks.
