The detection device that detects presence of an unauthorized message in an in-vehicle network, the detection device includes: a state detection unit configured to detect a transition to a state in which a periodic message is transmitted in an in-vehicle network, based on content of a message transmitted in the in-vehicle network; and a processing unit configured to perform detection processing to detect presence of the unauthorized message based on a reception status of a plurality of the periodic messages in the state detected by the state detection unit.

Virtual sensor technology, in which a camera is controlled to capture at least one configuration image of an area monitored by a monitoring system and input is received that defines one or more characteristics of the at least one configuration image that enable sensing of an event in the area. Based on the received input, configuration data used in sensing the event is generated and stored. After storage of the configuration data, the camera is controlled to capture one or more images of the area, the one or more images are analyzed based on the configuration data, and occurrence of the event is detected based on the analysis of the one or more images. Based on detecting occurrence of the event, a transmitting device is controlled to send, to a controller of the monitoring system, a signal that indicates the detection of the occurrence of the event.

A network-based line-rate method and apparatus for detecting and managing potential malware utilizing a black list of possible malware to scan content and detect potential malware content based upon characteristics that match the preliminary signature. The undetected content is then subjected to an inference-based processes and methods to determine whether the undetected content is safe for release. Typical to inference-based processes and method, the verdict is a numerical value within a predetermined range, out of which content is not safe. The network content released if the verdict is within safe range, otherwise, the apparatus provides various options of handling such presumably unsafe content; options including, soliciting user input whether to release, block, or subject the content to further offline behavioral analysis.

An example non-transitory computer-readable medium stores instructions that, when executed by a control device, cause the control device to perform functions. The functions comprise configuring a first playback device associated with a first user-account to (i) play media content from a playback queue comprising one or more audio tracks stored at a network location and (ii) enable one or more other user-accounts associated with other playback devices to subscribe to the playback queue. The functions further comprise receiving an indication that a second user-account associated with a second playback device has subscribed to the playback queue. The functions further comprise in response to receiving the indication, displaying a subscriber indicator on the control device showing that the second user-account has subscribed to the playback queue. An example control device and an example method, both related to the example non-transitory computer-readable medium, are also disclosed herein.
