Abstract

A novel use of visual cryptography is to ensure safe bio-metric authentication in the healthcare industry. The necessity for strong authentication techniques is due to the growing digitization of records and the growing reliance on electronic health systems. There are now a lot of obstacles because of security and privacy issues with conventional bio-metric authentication techniques.Visual cryptography can be done using many algorithms for image encryption. This paper presents a method to encrypt images using two main encryption algorithms: the Advanced Encryption Standard and the Shamir Secret Sharing Scheme. AES, a widely used symmetric encryption algorithm, provides high security by converting plain text to ciphered text using a key which is symmetric. By using the Shamir algorithm, the system creates and saves encrypted images using visual cryptography. In the health care industries, biometric samples are presented as part of the authentication procedure; these samples are divided into shares and encrypted. The shares are subsequently given to the healthcare professionals, who authenticate patients using their unique shares and the help of the central server. By preventing the disclosure of any critical information to a single party, the visual cryptography technology reduces the possibility of data breaches.
