A Play-Fair Cipher Based Authentication Medical Data Image Transaction Process

Abstract

The medical images which contain patient information need to be transaction from one doctor to another doctor. Patients who live in remote areas are able to communicate with the healthcare provider and benefit from the doctor consultations. However, it has been a challenge to provide a secure telemedicine system, which captures the user’s mobility and patient privacy. Message authentication is a mechanism or service, used to verify the integrity of a message. Integrity and source authentication is achieved by using Message Authentication Codes. The Play-fair cipher is a manual symmetric encryption cipher. The play-fair cipher starts with creating a key table. The kay table is a 5*5 grid of letter. This application applies to Network security, personal data protection, payment security, database security, preservation and confidentiality of information.
