Executive
18、 summary ICT is moving towards a genuinely distributed and virtualized environment characterized by a rich set of mobile and cloud services available to users. In this context, it may be difficult to have a priori knowledge of who may need access to data, when and where this may happen and whether t
19、hat data could be or contain Personally Identifiable Information (PII). The present document proposes a number of scenarios focusing on todays ICT and develops an analysis of possible threats related to PII in mobile and cloud based services. It also presents technical challenges and needs derived f
20、rom regulatory aspects (lawful interceptions). The aim is to consolidate a general framework, in line with regulation and international standards, on top of which technical solutions for PII protection can be developed.

21、number of scenarios focusing on todays ICT and develops an analysis of possible threats to Personally Identifiable Information (PII) in mobile and cloud based services. It also presents technical challenges and needs derived from regulatory aspects (lawful interceptions). It consolidates a general f
22、ramework, in line with regulation and international standards, where technical solutions for PII protection can be plugged into. 2 References 2.1 Normative references Normative references are not applicable in the present document. 2.2 Informative references References are either specific (identifie
