Cassidy is a medical assistant in a hospital and has access to many medical files. When she brings patients to the examining room, she can be observed swiping a card, typing in a password, and staring into what appears to be a camera, all attached to the computer. After completing her check-in, Cassidy leaves the patient in the examining room waiting on the doctor. It is important that she logs out of the system so the patient does not have access to the information stored in the hospitals database. Based on Cassidys actions what systems do you think the hospital has in place to protect the patient medical records?

a. Digital certificates

b. Two factor authentication

c. Biometrics

d. Encryption
