摘要: The invention provides for a solution enabling obtaining a control word in the client. The client device has a unique binary identification. An input transformed control word is mapped from an input transform domain to an output transform domain to thereby obtain an output transformed control word by successively applying a transformation function to the input transformed control word using each compound of seeds from the set successively as an input to the successive transformation functions. Each of the successive transformation functions is one of a regular transformation function, a first special transformation function and a second special transformation function. The obtained control word can be used to decrypt one of two copies of a part of content data. The copy that can be decrypted contains a watermark representing either a binary “0” or a binary “1” and represents a bit of the unique binary identification of the client device.

摘要: The invention provides a system and a method for securely providing a secret data from a sender to one or more receivers. The receiver uses a sequence of functions originating from a hierarchy of functions to migrate the secret data from an input transform space to an output transform space using a mathematical transformation under control of one or more seeds. The seeds are provided to the receiver by the sender. The sender conditionally allows the receiver to obtain the secret data by controlling the seeds.

摘要: The invention provides a solution for secure and non-manipulatable processing of a data stream in a receiver, possibly in conjunction with a smartcard. A packet identity and a content type identifier associated with the packet identifier are received in encrypted form and securely processed within the receiver to allow an encrypted payload of the data stream to be processed without the possibility to manipulate the content type identifier in an attempt to intercept the payload after decryption.

摘要: Embodiments of the invention provide an improved method and an improved receiver for obtaining a control word. Two or more subkeys are obtained in a receiver. Each subkey was encrypted under control of a key received in an entitlement message or transformed under control of a seed received in an entitlement message. After decryption or transformation, the subkeys are combined to obtain the control word. Typically at least one of the entitlement messages is a positive entitlement message and at least one of the entitlement messages is a negative entitlement message. Embodiments of the invention can be used in a conditional access system such as a Pay-TV system.

摘要: A computer-implemented method for a gesture-based user interface and a gesture-based user interface system are described. The method comprises receiving image data from a multi-aperture image sensor in said electronic device, said image sensor being configured to simultaneously expose an image sensor to at least a first part of the electromagnetic (EM) spectrum using a first aperture and at least a second part of the EM spectrum using one or more second apertures; determining sharpness information in at least one area of said image data associated with at least part of an object imaged by said first aperture and said one or more second apertures onto the image plane of said image sensor; generating depth information on the basis of at least part of said sharpness information; and, recognizing on the basis of said depth information, at least part of a gesture associated with a movement of said object.

摘要: A method and a system for forming an image of a scene are provided. The method includes capturing an image of the scene by exposing an image sensor to radiation from one part of the EM spectrum using one aperture and to radiation from another part of the EM spectrum using another aperture having a different size than the first aperture. Simultaneously with capturing the image, the scene is illuminated with radiation from the second part of the EM spectrum. The image is then formed on the basis of image data generated by the radiation from the first part of the EM spectrum and image data generated by radiation from the second part of the EM spectrum.
