Security and access control is provided for sensor devices, the data captured by sensor devices, and the results of processing and analyzing that data. In one aspect, SceneData related to a Scene is requested from a sensor-side technology stack and at least some of the SceneData is secured, for example by encryption. Different SceneData can be secured separately and at different levels of security, thus providing fine-grained security of the SceneData. In yet another aspect, data security is implemented by a separate privacy management system. In yet another aspect, sensor devices themselves are secured against external network threats. The sensor device includes an execution environment and a separate network management layer that secures the execution environment against threats from the external network. In one implementation, the sensor device is partitioned into a trusted region and a non-trusted region, and the network security stack is implemented in the trusted region.

Security for scene-based sensor networks, with access control

An approach to sensor data is based on scenes. One aspect concerns a computer-implemented method for specifying and obtaining a variety of sensor data and processed sensor data related to a scene. The method incorporates a Scene-based API that uses SceneModes and SceneData. An application requesting sensor data communicates a SceneMode to a group of one or more sensor devices and/or sensor modules via the Scene-based API. The SceneMode determines the SceneData to be captured or provided by the sensor group, which typically includes different types of sensor data related to the Scene and also further processed or analyzed data. The application receives the SceneData from the sensor group via the Scene-based API, with the SceneData organized into SceneShots which are samples of the Scene.

Scene-based sensor networks

Security for scene-based sensor networks, with privacy management system

Automated discovery of the relative positioning of a network of cameras that view a physical environment. The automated discovery is based on comparing TimeLines for the cameras. The TimeLines are time-stamped data relating to the camera's view, for example a sequence of time stamps and corresponding images captured by a camera at those time stamps. In one approach, the relative positioning is represented by a proximity graph of nodes connected by edges. The nodes represent spaces in the physical environment, and each edge between two nodes represents a pathway between the spaces represented by the two nodes.

Automated proximity discovery of networked cameras

A sensor device has a sensor base with a sensor mount, for which different sensor assemblies are attachable to the sensor mount. The sensor base transmits different settings to the sensor assembly via the sensor mount interface. The transmission preferably is wireless, rather than using mechanical connectors. The sensor assembly stores the settings in control registers that determine the settings for the capture of sensor data. In one approach, the sensor base includes an application processor and software executing on the application processor determines the settings. The control registers for the sensor assembly are thus software programmable, allowing different settings to be applied to different samples of sensor data.

Intelligent interface for interchangeable sensors

Security for scene-based sensor networks

The present disclosure overcomes the limitations of the prior art by providing 3D compression (i.e., compression that also accounts for changes in depth), including 3D compression of video sequences. In one aspect, depth information is obtained by processing captured images from a multi-aperture imaging device. The availability of IR images and depth information facilitates additional processing compared to when only color images are available.

Depth-based video compression

An application programming interface (API) provides access to a multi-aperture imaging system. By using the API, higher level applications can access and/or specify the image capture by the multi-aperture imaging device. For example, the API can support the specification of various image capture parameters: resolution, frame rate, exposure, flash, filtering, and additional processing to be applied. These could be specified for all frames and all channels (Red, Green, Blue and Infrared), or could be specified for specific subframes within a frame and/or for specific channels. The API can also specify output data from the multi-aperture imaging device. This can include raw pixel data, image data (color and Infrared), depth maps, and other processed image data. It can also include metadata and data about the status of the multi-aperture imaging device.
