An input mechanism for generating an input for a search engine, which is of particular use in searching medical databases comprising electrocardiogram (ECG) results. The input for the search engine is constructed in iterative stages, by initializing the input with a placeholder symbol, and iteratively replacing (responsive to a user input) placeholder symbols with input sections. An input section may comprise a variable to be searched, one or more additional placeholder symbols or a function.

Method and system for generating an input for a search engine

The invention provides a consent management system for managing a user's consent for a plurality of services. The system includes a consent management unit adapted to register a plurality of services to a user and obtain user consent information associated with the user. The consent management unit is further adapted to control consent operation of the plurality of services registered to the user, based on user consent information associated with the user.

System and method for consent management

Various embodiments relate to a method and apparatus for policy-hiding on ciphertext-policy attribute based encryption, the method including the steps of categorizing each of a plurality of attributes into a plurality of groups where each of the plurality of groups has a group attribute, inputting a policy and a message into an encryption algorithm and outputting a ciphertext; and encrypting an AND subtree in the policy and outputting a sub-cipher.

Method and apparatus for policy hiding on ciphertext-policy attribute-based encryption

Embodiments of the present disclosure relate to digital rights management. A method for managing rights transfer of using digital content from a first device () to a second device () is proposed, comprising generating at an authentication device () a first authentication dataset C by encrypting a first verification code Rusing at least one public key for at least one device blacklisted by the authentication device (). The first authentication dataset C and a second verification code Rare provided from the authentication deviceto the first device () and a response message M is returned from the second device () to the authentication device (). The method also comprises verifying validity of the second device () at the authentication device () based on the received response message M. In accordance with embodiments of the present disclosure, the DRM protected digital content can be shared with high security, while the recipient is kept anonymous to the DRM server.

Digital rights management for anonymous digital content sharing

This invention provides a method for managing a transaction right in a digital rights management server. The transaction right is the right to a transaction of a utilization right of a digital content item. The method comprises steps of obtaining an attribute associated with the digital content item from metadata of the digital content item; and generating the transaction right on the basis of a pre-stored rule and the attribute of the digital content item. Since the transaction right is generated on the basis of the attribute of the digital content item, or in other words, the transaction right is dependent on the attribute of the digital content item, the generated transaction right of digital content items can be different if the corresponding attribute associated with the digital content items are different. Furthermore, in additional to the metadata, the generation of the transaction right only requires the pre-stored rule, resulting in affordable complexity and cost. Since the transaction right is also dependent on the pre-stored rule, the content providers need not to individually set the transaction right for each digital content item, but are still able to set the transaction right by setting the pre-stored rule.

Method and apparatus for managing a transaction right

A system and method for providing directional information to a user using existing infrastructure elements () is disclosed. The method comprising determining a route of infrastructure elements () between a current location and a remote location, wherein the current location is associated a first element in the route and the last element in the route being closest to the remote location, wherein each of the elements in the route are identified by at least one of: a physical identification and a data identification, and providing a visual indication, progressively, to each of the infrastructure elements in the route at a predetermined time and for a determined period, wherein the progressive display of the visual indication provides for direction control information.
