  • Patent number: 7712131
    Abstract: A method, an apparatus, and a computer program are provided to secure diagnostic software from a software or hardware manufacturer for a computer. Traditionally, diagnostic software was distributed to professionals and other personnel in limited numbers. However, it was still possible to obtain unauthorized copies of the diagnostic software. Therefore, to alleviate the possibility of having unauthorized copies, a Universal Serial Bus (USB) memory device containing identification number can be used and a hidden partition that is inaccessible by an end-user where an encrypted version of the identification number is stored. In order to use diagnostic software, the specific USB memory device must be physically interfacing a computer. Hence, by limiting the number of USB memory devices, unauthorized copies can be prevented.
