PROBLEM TO BE SOLVED: To provide a method and device for enabling and supplying delayed decoding, since delayed decoding effects have not been applied to an independent receiver even though a decoding-enable time is designated as the decoding conditions, in an encryption system for suppressing the decoding of encrypted data, as long as decoding conditions are not fulfilled. SOLUTION: This information processing method comprises a process of receiving encrypted information or the other information and a process of decoding the encrypted information at a time which is not earlier than a designated time by using the other information. The other information includes data showing the point of time. COPYRIGHT: (C)2006,JPO&NCIPI
