System Control Unit (SCU)
General description
Hanscan's solutions are delivered standard with a secure System Control Unit (SCU) that serves as the central brain of every Biocryptology® System. The SCU is a server containing dedicated hardware and all of the required MABAS management software for the entire system. It contains the data repository, storing all registered user data as well as all of the events that have occurred at any of the terminals connected to the network.
Any transaction generated by a Hanscan terminal is authenticated through our Biocryptology® encrypted, secure System Control Unit, excluding occasions where access controls and time and attendance terminals are in the offline mode, where the authentication then takes place in the terminal itself.
The encryption process within the SCU is not executed by software, therefore preventing access to the file encryption keys. Instead, the System Control Unit encrypts information via an electronic encryption system, avoiding the storage of a security key and making the data unreadable to anyone, including Hanscan. Every bit of encrypted data is completely different from all other data in the system each time it is encrypted.
