|Abstract:||With the significant development of mobile commerce, the integration of physical, social, and cyber worlds is increasingly common.
The term Cyber Physical Social Systems is used to capture technology’s human-centric role. With the revolutionization of CPSS,
privacy protections become a major concern for both customers
and enterprises. Although data generalization by obfuscation and
anonymity can provide protection for an individual’s privacy, overgeneralization may lead to less-valuable data. In this paper, we
contrive generalization boundary techniques (k-anonymity) to maximize data usability while minimizing disclosure with a privacy
access control mechanism. This paper proposes a combination of
purpose-based access control models with an anonymity technique
in distributed computing environments for privacy preserving policies and mechanisms that demonstrate policy conflicting problems.
This combined approach will provide protections for individual personal information and make data sharable to authorized party with
proper purposes. Here, we have examined data with k-anonymity
to create a specific level of obfuscation that maintains the usefulness of data and used a heuristic approach to a privacy access
control framework in which the privacy requirement is to satisfy
the k-anonymity. The extensive experiments on both real-world
and synthetic data sets show that the proposed privacy aware access
control model with k- anonymity is practical and effective. It will
generate an anonymized data set in accordance with the privacy
clearance of a certain request and allow users access at different
privacy levels, fulfilling some set of obligations and addressing privacy and utility requirements, flexible access control, and improved
data availability, while guaranteeing a certain level of privacy.
