Title: Challenges on Anonymity, Privacy and Data Usefulness 

Abstract: Preserving individual privacy is one of the major issues in the context of Big Data, as while handling huge volumes of data, it is possible that sensitive or personally identifiable information ends up disclosed. In fact, even when dealing with anonymized raw data, sensitive information may be extracted through analytics. Preserving anonymity is particularly difficult because it should be done while allowing the analytics to produce useful insight about the data. K- Anonymity is a property for the measurement, management, and governance of the data anonymization. Many implementations of k-anonymity have been described in the state of the art, but most of them are not able to work with a large number of attributes that needs to be anonymized in a “Big” dataset. Moreover, K-anonymity needs to be traded-off against the usefulness of data. The goal is to discuss the tools, methodologies for data privacy protection with focus on anonymity that can cope with the challenges raised by Big Data and analytics processing, by finding a pseudo-optimal solution in a reasonable time over a considerable load of input, while preserving the usefulness and prevent loss of information.
