System and method of using RFID tag proximity to grant security access to a computer

摘要

A system and method of granting and removing a user's security access to applications on a computer using proximity of authorized RFID tags is disclosed. A user having an authorized RFID tag that is located near the computer will be granted access to pre-authorized applications.

1. A system for granting security access to one or more software applications on a computer, comprising:
an RFID reader configured to:
scan an RFID tag that is within a proximity range of the computer, andread identification data associated with the RFID tag in response to a proximity of an RFID tag to the computer being within the proximity range; a database storing specific software permissions that are associated with the identification data of the RFID tag, wherein the software permissions are for specific users to gain access to the one or more software applications; and a processor that:
compares the identification data associated with the RFID tag to the specific software permissions stored in the database in response to the RFID tag being detected to have entered the proximity range,grants access to only selected software applications on the computer if the comparison of the identification data associated with the RFID tag and the specific software permissions of a user associated with the identification data of the RFID tag is favorable based on the RFID tag entering the proximity area, wherein the access is limited to the specified permissions,denies access to predetermined software applications if the comparison of the identification data associated with the RFID tag and the specific software permissions is not favorable and if the RFID tag is within the proximity range;after the granting of access, determining if the RFID tag is still in the proximity range, and if the RFID tag is determined to still be within the proximity range, continuing to grant access to the selected software applications, but if the RFID tag is determined to not be within the proximity range, determining that the RFID tag has not been within the proximity range by determining that a lag time between the RFID tag and the RFID reader is greater than a predetermined threshold, and denying access to the selected software applications in response to determining that the lag time is greater than the predetermined threshold.
