Enhancing Medical Domain Data Security using Inbuilt Data Encryption and Steganography

The medical domain has seen an increased use of image steganography and encryption for securing medical pictures and data. Image steganography is the procedure of hiding a text (message) within a picture, while encryption of a message would be the state of transforming a readable message into an unreadable format. These two methods can be used together to provide a higher level of security for medical images and data. In this paper, The proper system for securing medical images and data using image steganography and encryption has been proposed. The proposed approach uses the Advanced Encryption Standard (AES) for encryption and decryption. Subsequently, the encrypted data is then embedded into a cover image using a steganographic technique, Linked Pixel pixel steganography. The methodology is tested on large data-sets that include various medical images and are evaluated on various performance parameters. The observations demonstrate that the suggested approach allows secure information transmission even though it is prone to threats.
