Verifying the authenticity of Employees entering nuclear complex

Nuclear facilities need very strict security mechanism to prevent unauthorized persons from gaining access to critical facility or approaching close enough to harm the facility. Physical Access Control System plays an important role in ensuring the entry of authorized personnel into the premises. There are so many ways by which this system can be designed and implemented, wherein the authenticity of the personnel can be verified including the photograph. Authentication process might be a multi factor with minimum of two factor authentication depending upon the critical nature of the facility. The paper presents how a novel embedded system based on BeagleBone Black evolved to authenticate the personnel by reading the credentials from the RFID based Identity card, fetching the photograph from the database and displaying on the monitor for positive identification of the photograph by the security personnel.
