Actuators and sensors in an intelligent system are controlled by setting encryption types and key lengths to individual applications based on the type of device and application being run. A server system (1) running in a communications gateway, selects an encryption policy for one or more devices under its control. This selection is controlled by an analysis function (11) using data relating to the type of device (13), and the applications to be run on the device (14), to generate an appropriate encryption policy (12) which can be deployed to the device (37). Controlling the analysis and deployment in a gateway device allows co-ordination between devices, and reduces processor time in the devices. An agent is sent to the device alongside the encryption policy data, to control the device according to the encryption policy. In response to events detected and analyzed by analysis function (10), the server sends triggers (45) to the agent loaded on the device to modify its encryption type in accordance with the policy previously deployed. Revisions and updates to the deployed policies can also be initiated, in response to dynamic factors such as resource usage (CPU, bandwidth, battery etc.), data sensitivity, external events and notifications of vulnerabilities to device type and applications used, in order to allocate resources more efficiently. Different encryption systems can be applied to different applications or data streams running on the same device, and encryption can be applied actively as and when required, using dynamic analysis of both the device and the application to encrypt data—for example to only encrypt if malware is detected.

Offline consumer behavior and interactions are observed using beacons positioned at venues where consumers spend time and interact with each other. The beacons communicate with mobile computing devices that are carried by the observed consumers. The observed consumer behavior provides actionable insights into how consumers influence each other. For example, the people that a particular consumer spends time with form a “circle of influence” associated with that consumer. If the consumer makes a purchase, members of the circle of influence are observed to understand the degree to which they were influenced by the purchase, if at all. Metrics that quantify a consumer's influence over other consumers allow marketers to more effectively target both the influencing and influenced consumers. Also, if relatively little information is known about a particular consumer, that consumer's digital marketing profile can be supplemented using information known about the consumers with whom he/she often spends time.

Arm actions indicative of upward, downward, or forward, actions may be identified based upon, for example, lifting, putting down, holding forward, actions, by using the key points of the human body, thereby achieving computer-level action identification, and lowering complexity of computation.

Examples of automatically generating natural language pipelines to process an input to generate tags, semantic or syntactic, are described. In an example, on receiving a request to process input data to generate tags, a dependency graph, based on identified dependees and further dependees may be created to satisfy the request, the dependency graph including natural language operations arranged in order of their dependencies on each other. Based on the dependency graph, a pipeline for the tags may be automatically generated, which includes a series of natural language operations such that the operations for dependee tags are processed before any of their associated depender tags. Further, the dependency graph and the automated pipeline generation allows for automated optimization of the pipeline, training, re-training, testing and regression testing of the semantic tags and supporting machine learning models and provides a framework to efficiently manage the sharing and reuse of semantic understanding operations.
