Abstract: Techniques are described for providing remote device (e.g., thermostat, lighting, appliance, etc.) control and/or energy monitoring. A system monitors sensor data captured by one or more sensors that sense attributes relevant to user presence at one or more monitored properties and status of one or more energy consuming devices associated with the one or more monitored properties. The system analyzes the monitored sensor data and the monitored device status with respect to a set of one or more rules and performs an operation related to controlling the one or more energy consuming devices based on the analysis of the monitored sensor data and the monitored device status with respect to the set of one or more rules.

Abstract: Techniques for generating a data representation without access to content are described. A method for generating a data representation without access to content comprises receiving a request to analyze one or more data items in a protected area of the provider network, sending the request to the protected area of the provider network, wherein the cluster model is used to identify a cluster identifier associated with each of the one or more data items, receiving the cluster identifier associated with each of the one or more data items, and regenerating each of the one or more data items based on the cluster identifier.

Abstract: A smart card comprising a data store and a processor, said smart card being operable to connect with a host data processing apparatus, said smart card comprising authentication logic operable when connected to said host data processing apparatus to identify a secure data processing domain having predetermined properties within said host data processing apparatus and in response to identify said secure data processing domain, said smart card is operable to delegate at least some data processing operations to be processed within said secure data processing domain of said host data processing apparatus.

Abstract: A data processing apparatus and method are provided for managing access to a display buffer. The data processing apparatus has a display buffer for storing an array of display elements for subsequent output to a display controller, with each display element having a security permission indication associated therewith identifying whether that display element is a secure display element or a non-secure display element. At least one processing unit is provided for executing a non-secure process and a secure process, each process issuing access requests when seeking to access display elements in the display buffer, and each access request specifying a location in the display buffer. Interface logic is associated with the display buffer for receiving each access request and is arranged for at least each access request issued by the non-secure process to determine the security permission indication associated with the display element currently stored at the location specified by that access request.

Abstract: A method of impeding leakage of cache access behavioral information of a section of a sensitive process to an untrusted process, said sensitive and untrusted processes being performed by a processor within a data processing apparatus, said data processing apparatus further comprising at least one cache operable to store information required by said processor while performing said sensitive and untrusted processes, the method comprising the steps of prior to commencing processing of a section of said sensitive process by said processor, evicting information stored in locations of said at least one cache which may otherwise be evicted by said sensitive process loading information that may be required by said section of said sensitive process in said at least one cache; commencing processing of said section of said sensitive process by said processor; switching said processor during processing of said section of said sensitive process to said untrusted process in response to a switching request; on switching bac

Abstract: A data processing apparatus is disclosed that comprises: at least one processor; a display for displaying data processed by said at least one processor; at least one display buffer for storing an array of display elements for subsequent output to said display, said display elements being secure display elements for displaying secure data and non-secure display elements; and a user interface; wherein said at least one processor is operable to execute at least one untrusted process and at least one secure process, said at least one secure process having access to secure data; said data processing apparatus further comprising: a secure user input for receiving a user input, said received user input not being accessible to said at least one untrusted process; and said data processing apparatus being responsive to an input received at said secure user input to transform data to be displayed on said display such that said secure display elements and said non-secure display elements are transformed differently to ea
