A radio frequency identification (RFID) tagging system for computer network assets comprises: an RFID host (22); a transponder tag (20) attached to an asset in a computer network, the tag having stored therein tag identifying data, inventory data describing the asset and security data; an electronically erasable and programmable memory (EEPROM) (18) adapted for operation as part of the asset (12); an RFID reader/writer (24) for reading data from the tag in an interrogation zone; respective communications links (26, 28) between the RFID host (22) and each one of the RFID reader/writer (24) and the asset (12), enabling the tag identifying data and the inventory or security data to be transferred between each of the RFID host (22), the EEPROM (18) and the tag (20), the inventory data also being stored in the EEPROM (18); and a control arrangement in the RFID host (22) and in the asset (12) for enabling operation of the asset (12) only in response to a predetermined communications sequence between the RFID host (22) and the asset (12) over the respective communications link.

RFID tagging system for network assets

A method and apparatus for controlling access to at least one program on a computer by verifying data entered through a scanner with data stored on a token such as a card, while isolating the entered data from the computer. The apparatus includes a scanner, a memory and a processor coupled to the scanner and memory. When activated, the scanner scans a field which the processor compares with a field stored in the memory. The processor is operable in a first mode wherein access to the computer via a keyboard is inhibited when the scanned field does not match the stored field. The processor is operable in a second mode, wherein the keyboard is coupled to the computer so that the at least one program on the computer is accessible via the keyboard when the scanned field matches the stored field. Various embodiments are disclosed.

Apparatus and method for providing an authentication system based on biometrics

A system controls acccess to a personal computer (10). The personal computer includes a microprocessor (22); a floppy disk controller (24); a floppy disk drive (26); a hard disk controller (28); a hard disk drive (30); a system memory (31); and, a video controller (32). An internal data bus (34) interconnects the components in a conventional way. Peripheral devices include a keyboard (35); a mouse (36); and, a printer (38). The personal computer further includes several lines (40, 42, 44, 58); several bus lines (52, 54, 56); several ports (46, 48, 50); and, a monitor (60).

Security access and monitoring system for personal computer

A security system for stand alone and portable computer hosts which utilizes both a hardware key and a password key to enable-access to the computer host. The entry of the password key and the hardware key is monitored by the keyboard controller. The keyboard controller alters a status bit during the POST portion of the host code if access is granted. The host security is divided into two levels of security, a first administrative level and a second user level. The administrative level is accessible by the entry of a first password or by the hardware key and enables access to all levels of the host SET-UP configuration. The user level is accessible by the entry of a second password and only enables access to a limited portion of the setup configuration.

Security system for a stand-alone computer

System and method for securely backing up and reliably retrieving vault data in a metering system that includes a host processor operatively coupled to a vault. Whenever a transaction is completed by the vault, the vault cryptographically signs the vault data, including ascending register, descending register and piece count and sends the cryptographically signed vault data to the host processor where it is stored in a data file assigned to the vault. Each storage of the cryptographically signed vault data is indexed to create a historical log of vault transactions. If the vault is lost or damaged so that vault data cannot be retrieved from the vault, the cryptographically signed vault data is retrieved from the host processor data file and verified.

System and Method for Disaster Recovery in an Open Metering System

A security system for a computer (10) having at least one communications port (12) for connection to peripheral devices, includes a card reader (14). A switching means (22) connected to the card reader and connectible to the communications port, is operable to connect the card reader to the communications port in response to a command including protected routines which generate said command to cause the switching means to connect the card reader to the communications port. Suitable software compares data from a card read by the card reader with authorisation data held in the computer, to enable or disable further operation of the protected routine(s).
