Abstract: An apparatus, computer-implemented method and computer program are disclosed for organization and analysis of high-scale low-signal (HSLS) data. The method may comprise providing one or more raw datasets representing CDRs and processing the raw datasets to generate an object-relational model comprising a plurality of objects, each object having an object type and properties of the respective object type. The method may also comprise receiving at least a first query comprising, for at least one object type of the object-relational model, at least a first property relating to a first investigation and applying the at least first query to the stored object-relational model to generate a first subset of the CDRs. Responsive to selection of an analysis command, the method may comprise performing a predetermined type of analysis associated with the analysis command on the first subset of CDRs to produce a resultant subset of the CDRs.

Abstract: A computer-implemented method, system and computer program is disclosed. The method may comprise providing an image comprising a plurality of pixels, identifying at least one portion of the image to be obfuscated, modifying pixels of the at least one image portion using a key for producing an updated image in which the at least one image portion is obfuscated, providing the key, or a link to the key, in an access profile for the identified at least one image portion and allocating permissions to one or more users for enabling them to view the at least one image portion, by use of the key, when viewing the updated image.
