Abstract: A method, an entity, and a system for managing access to data. The data is associated with metadata. At least one predetermined access policy for accessing metadata includes, for each client, at least one identifier relating to the client. An entity receives from at least one client device, a data access request that includes at least one identifier relating to the client. The entity determines, based on the associated access policy, whether the metadata access is authorized. If yes, the entity determines, based on the associated access policy, associated first data allowing to access the metadata. The entity accesses, based on the first data, the associated metadata. The entity accesses, based on the accessed metadata and the associated access policy, at least a part of the associated data, as a late dynamic binding of the metadata with the associated data (or a part of it).

Abstract: The invention relates to a method for managing data access. The method includes receiving at least one request for accessing data; capturing data relating to at least one current context signal during each data access request; comparing, as a current authorization step, the data relating to at least one captured current context signal to predetermined reference data relating to at least one corresponding context signal according to at least one corresponding predetermined authorization policy; determining, based upon the current authorization result and at least one predetermined dynamic data access policy, whether the data access is or is not authorized, as a data access decision; and issuing the data access decision. The invention also relates to corresponding first device, second device and system.

Abstract: An image pipeline performs image processing operations (for example, Bayer-to-RGB conversion, white balancing, autoexposure, autofocus, color correction, gamma correction, zooming, unsharp masking, mirroring, resizing, color space conversion) on tiles whose sizes are varied, whose widths are less than the width of the output image frame being generated, and whose heights are less than the height of the output image frame. A tile processor program executing on a processor in the camera determines configuration information for configuring each pipeline stage based on user input and camera usage. The configuration information is determined so that the pipeline outputs properly combine to form the output image frame. The sizes, shapes, locations and processing order of the tiles are determined such that a single tile of a particular size is in a desired location with respect to the overall image frame, thereby facilitating such functions as autofocus, autoexposure and face detection.
