ABSTRACT:
A method and system for creating a permanent and authentic history of a computer generated numerical digit enables one to track digit's life path. The method comprises embedding each digit with a tamper detectable date-time stamp including at least the date when the digit is generated in the computer. The system includes an encoder for providing the numerical digit with the date stamp, a storage for storing the encoded numerical digit, and a decoder for decoding the numerical digit to indicate at least the date of origin of the numerical digit.
