System and Method of Secure Logon for Shared Devices

摘要

A system includes a sensor to determine a user is proximate to the system and a logon module to receive information from the sensor that a user is proximate to the system, receive logon information from the user and identification information associated with the user, authenticate the user to use the system based on the logon information, store the identification information, receive second information from the sensor that the user is not proximate to the system, suspend an operating system session, receive information from the sensor that the user is again proximate to the system, receive second identification information associated with the user, determine that the first and second identification information matches, and resume the OS session in response to determining that the first and second identification information matches.

1. An information handling system comprising:
a first sensor operable to determine that a user is proximate to the information handling system; an authentication database comprising user authentication information; and a logon module operable to:
receive first information from the first sensor that the user is proximate to the information handling system;receive first logon information from the user and first identification information associated with the user in response to receiving the first information from the first sensor;authenticate the user to use the information handling system based on the first logon information, the first identification information, and first user authentication information from the authentication database;store the first identification information;receive second information from the first sensor that the user is not proximate to the information handling system;suspend a first operating system session in response to the second information from the first sensor;receive third information from the first sensor that the user is proximate to the information handling system;receive second identification information associated with the user in response to the third information from the first sensor;determine that the first identification information matches the second identification information and first user authentication information; andresume the first operating system session in response to determining that the first identification information matches the second identification information and first user authentication information.
