Steganographic Methods Performance in Medical Imaging

Abstract

It is now simpler and faster to convey correct data to its destination because to the internet's tremendous progress in data transfer. Hacking is used by unauthorised users to alter and misuse sensitive data. Thus, a variety of techniques, including as cryptography and steganography, can be used to safely transport the data to its destination unaltered. Information sharing and transfer have grown dramatically in the information age. While being stored or sent, the information is susceptible to illegal access and interception. The primary method for communicating covertly is steganography. Image steganography and its various security techniques are used in research projects to protect medical images, especially those obtained by magnetic resonance imaging (MRI). The hidden message's contents are incorporated into the cover medium during the steganography process. The Least Significant Bit (LSB) algorithm, Division into Block, and Mean Change Modified Method are the three steganographic algorithms that are employed. To compare them in terms of speed and accuracy, the metrics SSD (Sum of Squares of Differences), SAD (Sum of Absolute Differences), MAD (Maximum Absolute Differences), and PSNR (Peak Signal to Noise Ratio) are utilised.
