Abstract
An information processing apparatus includes a first processing circuit having a capability of decoding encoded stream data input to the first processing circuit and a capability of detecting tampering on encryption information, the first processing circuit being configured to, if tampering is detected, add a tamper flag to the tampered data, a second processing circuit configured to perform a predetermined process on data output from the first processing circuit, and, if the data includes the tamper flag, add tamper information indicating the fact being subjected to tampering to the processed data, and a third processing circuit configured to receive data output from the second processing circuit and process the received data such that when the received data does not include tamper information, the received data is processed in a normal manner, but when the received data includes tamper information added thereto, the received data is processed differently from the normal manner.
