A method and system for media consumption are described. The method including tagging each one of a plurality of content items with at least one metadata tag, the metadata tag including a descriptor of at least one topical attribute describing the content item, the plurality of content items being adapted for consumption on a plurality of user devices, wherein the plurality of content items are provided in multiple file formats; acquiring a history of user consumption of the plurality of content items on a plurality of user devices associated with a single user; storing a user record including the acquired user history, a plurality of metadata tags associated with user consumed content, and including a list of devices comprising the plurality of user devices associated with a single user; building a playlist based, at least in part, on the following criteria, wherein each content item which is listed on the playlist has at least one tag which is also one of a plurality of tags already stored in the user record: a) including a content item which has been started but not completely consumed, b) not including content items marked in the acquired history as being completely consumed, unless the content items have changed with respect to the version consumed, and c) including content items which have not been consumed; selecting at least one content item from the playlist; and pushing the selected at least one content item to at least one of the plurality of user devices associated with a single user, wherein if the selected at least one content item is not suitable for consumption on the at least one of the plurality of user devices, then a next item in the playlist is pushed to the least one of the plurality of user devices.

Continuity of content

In one embodiment a method, apparatus and system for is described for receiving a first input including a first decryption key and a second input including an encrypted second decryption key at a cryptographic decryption apparatus, the encrypted second decryption key to be decrypted by the cryptographic apparatus according to the first decryption key, storing a value of a key ladder length in a first register by a cryptographic processor, and using the stored value as a loop index by the cryptographic processor for a number of iterations of the cryptographic decryption apparatus executed as a loop, wherein at one stage in the loop execution of the cryptographic decryption apparatus, the second input includes the key ladder length, wherein the loop operation of the cryptographic decryption apparatus operates for a number of iterations equal to an initial value of the loop index. Related methods, apparatuses and systems are also described.

Key ladder apparatus and method

A method and system for fingerprinting a content item is described, the content item including a set of content item elements E, providing information uniquely associated with a single user including a string of bits S, parsing Sinto a plurality of substrings which are functions of S, providing a matrix of content item replacement elements, each row of which includes, for each member of E, an array of content item replacement elements for E, uniquely associating each substring of Sso that for every substring there exists a corresponding element of E, for every substring, replacing at least one instance of the corresponding element E in the content item with one substitute matrix element for the corresponding substring, and outputting a replacement content item including the result of the replacing, the substitute matrix elements being chosen according to at least one similarity criterion.

Electronic book security features

A method and system for securing a read write storage (RWS) device, the method comprising, providing the RWS device, the RWS device comprising a controller comprising a processor and a bit bucket storing data, and employing the controller to corrupt at least a portion of the data.

Secure read-write storage device

A method is described for securing a read write storage (RWS) device, the method comprising, providing the RWS device, the RWS device comprising a controller comprising a processor and a bit bucket and employing, in response to a decision making process, a sanction in the RWS device. Related apparatus and methods are also described.

A method for producing scrambled content (FIG.A), the method including providing content () to be scrambled, identifying a first portion of the content (), identifying a second portion of the content (), computing a disguising function of at least part of the first portion () of the content and producing a result, and scrambling the second portion () of the content, the scrambling being based in part, on the result. Related apparatus and methods are also described.

Digital video recorder anti-skip system

A method for managing dynamic program changes in a digital video broadcasting (DVB) system, the method including detecting a dynamic program change in a DVB transmission received at a set-top box (STB), and changing a digital video recorder (DVR) recording instruction associated with the program to record the program in accordance with a parameter of the change.

Management of dynamic program changes in DVB systems

A method for frustrating piracy of a movie, the movie including a plurality of filmed frames, each of the filmed frames including an image, the method including editing the movie prior to projection such that different regions of the image of one of the filmed frames are in different frames so that the different regions will be projected at different times, and repeating the editing for other ones of the filmed frames. Related apparatus and methods are also described.

Movie copy protection

Apparatus comprising a secure time element comprising a timing device that outputs to a plurality of delay devices, wherein the delay devices have characteristic delay times which are alterable as a result of a tampering attempt to tamper therewith, and wherein a characteristic delay time of one of the delay devices changes differently from another one of the delay devices as a result of the tampering attempt.
