Claim 0:
1. A surveillance system for mobile communication devices comprising:
one or more processors;
an anonymization module configured to, by the one or more processors: receive, for each one of a multitude of individual objects, each being a mobile communication device, in a population of individual objects, identifying information representative of an identity of the individual object, wherein the identifying information representative of the identity of the individual object includes and/or is based on mobile identifying information including at least one of mobile phone number, mobile subscriber identity and mobile equipment identity, and to generate anonymous identifier skew measures based on identifying information of one or more individual objects, wherein said anonymization module is configured to, by the one or more processors: perform anonymization into an anonymous identifier skew measure effectively online, that is in real-time and/or near real-time, immediately deleting the identifying information after processing;
a memory configured to store at least one anonymous identifier skew measure based on at least one of the generated identifier skew measures;
an estimator configured to, by the one or more processors: receive, from said memory and/or directly from said anonymization module, a number of anonymous identifier skew measures, at least one identifier skew measure for each of at least two tempo-spatial locations of individual objects, and
wherein said estimator is configured to, by the one or more processors: generate one or more population flow measures related to individual objects passing from one tempo-spatial location to another tempo-spatial location based on the received anonymous identifier skew measures.
