One of the challenges of telemedicine as observed in the literature is the issue of insecurity of data. This has come with its attendant lack of confidentiality and data integrity, the attributes most needed in medical records. An attempt to proffer solution to this problem is in the design of a framework comprising Rivest, Shamir and Adleman (RSA) cipher combined with the F4 frequency domain steganography algorithm. The framework is demonstrated with a simulated scenario. Complicated though this integration seems to be, the foolproof security offered outweighs the computational complexity.
