Abstract:
1. A non-transitory computer-readable medium comprising computer executable instructions that, when executed by a computer, causes the computer to create a product control sequence for a product piece, the computer-readable medium storing one or more instructions for: generating an encoded check sequence by encoding a product-specific identification sequence or by encoding a sequence derived from the product-specific identification sequence, wherein the encoding is performed with the aid of a symmetric encoding method and using a secret encoding sequence; generating a hash sequence using a hash method and the encoded check sequence or the sequence derived from the encoded check sequence; encoding the hash sequence using the secret encoding sequence to form an encoded hash sequence; and creating the product control sequence by combining the encoded hash sequence and one of the product-specific identification sequence or the sequence derived from the product-specific identification sequence.
