This paper explores recent achievements and novel challenges of the annoying privacy-preserving big data stream mining problem, which consists in applying mining algorithms to big data streams while ensuring the privacy of data. Recently, the emerging big data analytics context has conferred a new light to this exciting research area. This paper follows the so-depicted research trend.
The data anonymization landscape has become quite complex in the last decades. On the methodology side, the statistical disclosure control methods designed in official statistics have been supplemented by a number of privacy models proposed by computer scientists. On the data side, static data sets now coexist with big data, and particularly data streams. In the quest for a unified and conceptually...
Set-valued data is comprised of records that are sets of items, such as goods purchased by each individual. Methods of publishing and widely utilizing set-valued data while protecting personal information have been extensively studied in the field of privacy-preserving data publishing. Until now, basic models such as k-anonymity or km-anonymity could not cope with attribute inference by an adversary...
Cloud users have little visibility into the performance characteristics and utilization of the physical machines underpinning the virtualized cloud resources they use. This uncertainty forces users and researchers to reverse engineer the inner workings of cloud systems in order to understand and optimize the conditions their applications operate. At Massachusetts Open Cloud (MOC), as a public cloud...
