Privacy Preservation Using 2-Degree Anonymity With Trust Circle in Ubiquitous Network for Service Communications

The ubiquitous networks bring lots of convenience to consumers and service providers for their service communications but have strong privacy issues. Such network environments are unobtrusive and imperceptible to the consumer, where services are provided through an omnipresent way in smart environments. It raises numerous privacy and security issues for consumers. Privacy of service communicating entities needs to be preserved from malicious entities in the context of three-fold privacy threat - identity, location, behavioural privacy threat of legitimate entities in ubiquitous environment. In this paper, privacy preservation is explored with two levels of anonymization by a 2-degree anonymity approach through trust circle of one service entity in service communication. Our proposal provides the personalization in-between anonymity and trust. Simulation results exhibit the effectiveness of our proposal in the considered environment with the “ADULT” database and “Facebook” data set of two Universities, Amherst, and Colgate.
