Classification: CPC H  G | IPC G  H

Claim 7:
8. A computer for counteracting an anomalous frame transmitted on an on-board network of a single mobility entity, the on-board network of the single mobility entity joining multiple electronic control units installed inside the mobility entity, the multiple electronic control units performing communication of a frame inside the single mobility entity, the computer comprising:
processing circuitry; and
a storage including at least one set of instructions that, when executed by the processing circuitry, causes the processing circuitry to perform operations, the operations including:
assessing, based on first information about the multiple frames received on one or multiple on-board networks of one or multiple mobility entities and second information about the frame received on the on-board network of the single mobility entity after the multiple frames are received on the one or more multiple on-board networks of the one or multiple mobility entities, an anomaly level of the frame received on the on-board network of the single mobility entity, the anomaly level of the received frame being a degree to which said received frame is considered to be anomalous; and
deciding whether or not to transmit a first alert to the single mobility entity based on the anomaly level, and deciding whether or not to transmit a second alert to a manufacturer of the single mobility entity or a security provider based on the anomaly level,

wherein the processing circuitry differently decides whether to transmit the first alert and the second alert for at least one anomaly level.
