Abstract: A method includes: providing a workstation having a playback app configured for audio playback; providing a decryption module having a decryption functionality communicatively connected to the playback app; encrypting, by a server using an encryption key associated with the decryption module, audio data; and decrypting, using the decryption module, the encrypted audio data. The decryption module having the decryption functionality is provided as part of the playback app, as part of firmware of a headphone, or as part of a phone app. The method can additionally include: i) authenticating, using a voice biometric authentication module, a transcriber; ii) enabling decryption by the decryption module only upon input of a decode PIN by the transcriber; and iii) a) modifying the audio data to spatialize speech component and noise component of the audio data at different angles using head-related transfer function (HRTF) filtering, and b) playing back the audio data binaurally.

Abstract: A mobile telephone system (1) is provided which allows users to store photographs taken by using their mobile telephone (31-1, 3-2), in a central storage and retrieval system (7). The mobile telephone allows the user to add an annotation to the photograph for use in retrieving the photograph at a later time. At the time of retrieval, the user inputs a text or spoken query into the mobile telephone which is transmitted to the central storage and retrieval system and is used to identify the image to be retrieved. The identified image is then transmitted back to the user's mobile telephone for further use.

Abstract: Initially an embedding module (22) determines an embedding of a lattice in a two-dimensional plane. The embedding module (22) then processes the initial embedding to generate a planar graph in which no links cross. The planar graph is then simplified by a link encoding module (24) and data representing the lattice structure is generated by a shape encoding module (26)—in which the simplified planar graph is represented by a shape encoding (42) identifying the numbers of links bounding areas defined by the planar graph and data identifying the locations of those areas within the planar graph; and a link list (43) identifying the modifications made to the lattice structure by the link encoding module (24). These encodings are such that the same substructures within a lattice are represented using the same data and hence are suitable for compression using conventional techniques.

Abstract: Apparatus for processing a set of items of related user input data to facilitate the carrying out of a task has an interpreter (500) that is arranged to interpret a set of items of user input data to produce a corresponding set of interpretation results data including interpretation results data for each item of user input data. The interpreter (500) is arranged to constrain interpretation of an item of the set of user input data on the basis of constraint data related to the interpretation results data obtained for at least one other item of the set of user input data items. A controller (8) of the interpreter is arranged to detect an occurrence of an interpretation error in the interpretation results data for an item in the set of user input data items.
