Abstract: A server includes: an obtainer that obtains items of information including an item of frame information regarding a communication frame transmitted on an in-vehicle network of each of a plurality of vehicles; and a generator that generates an integrated rule that is suitable for the items of information obtained by the obtainer and is for anomaly detection processing in the in-vehicle network of one of the vehicles; and a provider that outputs the integrated rule generated by the generator. For example, the obtainer obtains condition information indicating a condition pertaining to each of the plurality of vehicles at a time when the communication frame is transmitted on the in-vehicle network, and the generator generates the integrated rule using the items of frame information associated with the condition information.

Abstract: A data processing device for playing back a digital work reduces the processing load involved in verification by using only a predetermined number of encrypted units selected randomly from multiple encrypted units constituting encrypted contents recorded on a DVD. In addition, the data processing device improves the accuracy of detecting unauthorized contents by randomly selecting a predetermined number of encrypted units every time the verification is performed.

Abstract: A master control device is communicatively coupled to a first slave control device and a second slave control device via a first network and a second network, respectively. The master control device provides output data to the first slave control device based on input data received from the second slave control device. A monitoring apparatus which monitors an operation of the master control device stores determination data indicating a correspondence relationship between the input data and the output data, obtains the input data provided to the second network by the second slave control device and the output data provided to the first slave control device via the first network, and determines a presence or an absence of an anomaly in the operation of the master control device by determining whether the input data and the output data correspond to the determination data.
