Abstract

A medical device as provided here includes a security module configured to regulate operations of the medical device. The medical device also includes a fingerprint reader operatively coupled to the security module. The fingerprint reader is configured to detect fingerprints, and to generate fingerprint data corresponding to swiped fingerprints. The medical device also includes at least one memory element operatively coupled to the security module, and configured to maintain a list of fingerprint-secured operations of the medical device, each of the fingerprint-secured operations being linked to a respective assigned set of identifiable fingerprint data. The security module is configured to analyze a swiped set of fingerprint data, compare the swiped set of fingerprint data to identifiable fingerprint data maintained in the list, and initiate one of the fingerprint-secured operations when the swiped set of fingerprint data satisfies matching criteria for its respective assigned set of identifiable fingerprint data.
