Abstract: Future networks will be characterized by a dramatic increase in terms of capacity, traffic volume, number of delivered flows, and diffusion capillarity. The emerging concern is how to avoid that a massive gathering of measurement data, and the possible misuse of such collected data, may become a threat to the network customers privacy. To face this issue, we believe that network monitoring architectures should be rethought so as to incorporate a privacy preservation operation in their design. This paper addresses such issue by describing a two-stage network measurement architecture that separates monitoring tasks between a front-end and a back-end. The frontend bserves, pre-processes, and protects measured network traffic, hile the back-end provides access control, post-processing, and data and result storage services. The system effectively separates trust between the stages, applying novel data protection and reduction techniques as early in the monitoring process as possible, and protecting stored data with a finegrained semantic access control scheme.
