  • Detecting corruption in a computer program at execution time using a checksum
    Patent number: 5493649
    Abstract: A mechanism for detecting corruption of computer programs is provided. In a preferred embodiment of the present invention, a checksum is used to determine when a computer program has been corrupted. Upon initially starting a computer program, a first checksum is calculated for the computer program. When the computer program is requested to perform an operation, a second checksum is calculated for the computer program.
