PROBLEM TO BE SOLVED: To provide a technique that can prevent, when data is traded in a data market, the traded data from illicitly leaking out. ! SOLUTION: An information processing system, on the basis of information that specifies, by executing a defined way of processing on input data, a processing block to generate the result of execution of the processing block on the input data and restorability information that is associated with the processing block and indicates whether the processing defined by the processing block is a way of processing capable of restoring part or all of the input data (restorable processing) on the basis of the result of processing or is a way of processing incapable of restoration (irrestorable processing) and, if the processing defined by the processing block is restorable processing, restrains execution of the restorable processing on the input data. !
