USE OF MICROCOMPUTER SYSTEM FOR MEDICAL RECORD ENCRYPTION AND DECRYPTION USING A SEQUENTIAL PSEUDO-RANDOM KEY
Mel L. Barclay, Joshua S. Barclay · Cryptologia · 1982
Medical records often contain materials and information of a very private and personal nature. This paper presents a methodology for the use of microcomputers in the encryption and decryption of small volumes of medical information using BASIC programming and the Vigenere-Vernam cryption technique.
