Abstract
A lock base attached to a computer housing has a controller in circuit communication with a processor of the computer. A cable socket comprising a flash memory locks onto the lock base, two ends of an internal wire of the cable form a closed electric circuit loop with the lock base through the entirety of the body of the cable, and the controller performs a handshake with the processor of the computerized device and the flash memory that generates a checksum key stored on the flash memory, the computerized device requiring access to the checksum key on the flash memory for access to data on a memory device of the computerized device. Absent a keyed unlocking, the controller erases the checksum key from the flash memory in response to a break in the circuit loop or dislocation of the cable socket from the lock base.
