ABSTRACT:
A method for ensuring secure delivery of a computer system to a customer. The computer system includes a motherboard with a processor, a read-only memory, and a programmable memory. The method encodes onto the read-only memory an identification number for the computer system. The computer system is sent to the customer via a first delivery channel and the identification number is sent to the customer via a second delivery channel. When the computer system is initially booted after being sent, the computer system prompts for input of the identification number for the computer system. When the computer system receives an identification number that matches the identification number encoded onto the read-only memory, it stores an indication of the match in the programmable memory indicating that the identification number has been verified to be correct so that the computer system operates normally thereafter. When the computer system does not receive an identification number that matches the identification number encoded on the read-only memory, it performs a security measure to ensure that the computer system operates abnormally thereafter. In this way, the computer system and the identification number are sent separately to reduce the possibility of an unintended recipient receiving both the computer system and the identification number. In addition, if an unintended recipient receives the computer system and not the identification number, the computer system operates abnormally.
