Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Digital communication (Electrical engineering)
Classification: CPC G  H | IPC H

Claim 0:
1. An information processing apparatus comprising:
a processor; and
a memory storing program instructions that cause the processor to:
store, in a storage unit, first data output by a device or any one of a plurality of devices in association with a first feature context related to the first data, wherein the first data represents log data obtained in response to the device operating, and the first feature context related to the first data indicates a state associated with the device at a time of the log data being generated or acquired by the device; and
obtain a second feature context related to second data in a case where the second data is received from the device or any one of the plurality of devices, and analyze an anomaly of the received second data based on the received second data and the obtained second feature context and based on the first data and the first feature context stored in the storage unit,
wherein first anomaly information is calculated, the first anomaly information indicating a degree of anomaly of the first data,
wherein the processor registers, in the storage unit, the first anomaly information in association with the first data or the first feature context,
wherein the receiving of the second data is subsequent to the storing of the first data, and
wherein the anomaly of the received second data is analyzed based on the first anomaly information stored in the storage unit.
