I recently participated in a panel on “Big data in the telecommunications industry” at the 11th World Telecommunication/ICT Indicators Symposium (WTIS) held in Mexico from 4-6 December 2013. Going by the feedback from the Q&A session, two aspects rose to the front: Firstly the issue of “privacy” is on everybody’s mind going by the number of questions that came from the audience. Everybody seems to have his or her own viewpoint. UN Global Pulse, whilst acknowledging there are valid concerns that must be addressed (and they have a set of privacy guidelines for their own work) clearly doesn’t want the concerns to derail the efforts to utilize telecom network big data for social good. Telefonica, as an operator, was quick to point his or her own set of privacy guidelines that inform their big data work.
