Abstract: A cross reality system enables any of multiple devices to efficiently and accurately access previously stored maps and render virtual content specified in relation to those maps. Both stored maps and tracking maps used by portable devices may have wireless fingerprints associated with them. The portable devices may maintain wireless fingerprints based on wireless scans performed repetitively, based on one or more trigger conditions, as the devices move around the physical world. The wireless information obtained from these scans may be used to create or update wireless fingerprints associated with locations in a tracking map on the devices. One or more of these wireless fingerprints may be used when a previously stored map is to be selected based on its coverage of an area in which the portable device is operating. Maintaining wireless fingerprints in this way provides a reliable and low latency mechanism for performing map-related operations.

Abstract: A system and method for providing security to a network may include maintaining, by a processor, a model of an expected behavior of data communications over the in-vehicle communication network; receiving, by the processor, a message sent over the network; determining, by the processor, based on the model and based on a timing attribute of the message, whether or not the message complies with the model; and if the message does not comply with the model then performing, by the processor, at least one action related to the message.

Abstract: A system and method for providing security to a network may include maintaining, by a processor, a model of an expected behavior of data communications over an in-vehicle communication network; receiving, by the processor, a plurality of messages communicated over the network; determining, by the processor, based on the model and based on content attributes of the plurality of messages, whether or not at least one of the messages complies with the model; and if at least one message does not comply with the model then performing, by the processor, at least one action related to the message.

Abstract: A system and method for providing security to a network may include identifying a message sent over a network, the message related to a data transfer from an initiator to a target node, and transmitting, over the network, at least one disruptive message that causes the data transfer to fail.

Abstract: A system and method for providing security to a network may include monitoring, by a processor, traffic on a first and second network portions of an in-vehicle communication network; determining whether or not a first message detected on the first network portion is anomalous based on at least one of: an attribute of a second message detected on the second network portion and an absence of a second message from the second network portion over a predefined time period; and, if it is determined the first message is anomalous then performing at least one action.
