PROBLEM TO BE SOLVED: To provide an information processor for making it difficult to analyze the buried place of electronic watermark information, and for making it difficult to alter the watermark information. SOLUTION: This information processor 10 is provided with a storage circuit (random gate circuit 12) for storing a program and an arithmetic circuit (CPU 11) for executing the program. The arithmetic circuit accepts the input of read information for reading the watermark information, and the storage circuit is configured as a random gate circuit as the combination circuit of logic elements, and when readout information is inputted through the arithmetic circuit, information having the watermark information is outputted.
