A method of the invention manages data stream processing tasks of an application topology in a stream processing system, the stream processing system having one or more data producers, one or more compute nodes, and one or more result consumers, includes: assigning geographic scope granularities to the data stream processing tasks of the application topology; receiving, by a task manager from a result consumer of the one or more result consumers, a subscription in order to trigger data processing for computing a result, the subscription including geographic scope related information concerning the triggered data processing]; generating, by the task manager based on the geographic scope related information of the subscription, an execution plan including task instances for performing the triggered data processing; and generating, by the task manager from the execution plan, a deployment plan for deploying the task instances of the execution plan on the compute nodes.

A method for generating a virtual device resource (VDR) accessible by an application includes providing a request for discovery of information by one or more applications; converting the provided request into one or more requests for one or more BigData repositories, wherein the converted one or more requests are supported by the one or more BigData repositories and fit the provided request; transmitting the converted one or more requests to the one or more BigData repositories; executing the transmitted one or more requests resulting in one or more descriptions of virtual device resources; selecting one or more virtual device resources (VDR) based on the one or more descriptions; and generating the selected, one or more virtual device resources (VDR).

A method for protecting a user's privacy, wherein the user operates a communication device capable of processing context and wherein the user provides context information&#x2014;real context&#x2014;related to one or more reference context variables to a third party, is characterized in the steps of faking at least one of the one or more reference context variables, on the basis of the faked reference context variable, gathering real context information&#x2014;decoy context&#x2014;related to reference context variables other than the faked reference context variable, publishing the thus generated decoy context instead of the user's real context. In addition, a corresponding communication device is disclosed.
