1. A processing apparatus comprising: an execution unit that executes a predetermined processing; an execution request accept unit that accepts instruction information for instructing execution of a second processing including a plurality of first processing, and that accepts an execution request of the second processing; a process instruction unit that instructs, under a condition that one of a plurality of information leakage preventing processing to be executed can be executed in a case of processing one of the plurality of first processing which is requested by the instruction information so as to be executed by the execution unit except for information leakage preventing processing having been executed by a first processing apparatus other than the processing apparatus among the plurality of information leakage preventing processing, the execution unit to execute the one first processing, each of the plurality of information leakage preventing processing being a processing for preventing leakage of information which is performed at a time of executing the second processing instructed so as to be executed by the instruction information; an information leakage preventing process execution unit that executes, when the information leakage preventing processing to be executed can be executed in a case of processing the one of the plurality of first processing which is requested by the instruction information so as to be executed by the execution unit, the information leakage preventing processing; a recording unit that records, when the information leakage preventing processing to be executed is executed by the information leakage preventing process execution unit in a case of processing the one of the plurality of first processing which is requested by the instruction information so as to be executed by the execution unit, a fact of the execution of the information leakage preventing processing in the instruction information; and a transmission unit that transmits, when there is a second processing apparatus other than the processing apparatus, the second processing apparatus executing the plurality of first processing next based on the instruction information in a case of executing the one of the plurality of first processing by the execution unit, the instruction information and the execution request of the second processing.
