Achieving Data Integrity and Confidentiality Using Image Steganography and Hashing Techniques

Most existing steganography algorithms keen on achieving data confidentiality only by embedding the data into a cover-media. This research paper introduced a new steganography technique that achieves both data confidentiality and integrity. Data confidentiality is achieved by embedding the data bits in a secret manner into stego-image. Integrity is achieved using SHA 256 hashing algorithm to hash the decoding and encoding variables. The proposed model performed a high PSNR values for using a dataset of different image sizes with an average PSNR of 82.933%.
