profilr toward preserving privacy and functionality in geosocial networks
- 1. PROFILR Toward Preserving Privacy and Functionality in Geosocial Networks PROFILR Toward Preserving Privacy and Functionality in Geosocial Networks Profit is the main participation incentive for social network providers. Its reliance on user profiles, built from a wealth of voluntarily revealed personal information, exposes users to a variety of privacy vulnerabilities. In this paper, we propose to take first steps toward addressing the conflict between profit and privacy in geosocial networks. We introduce PROFILR, a framework for constructing location centric profiles (LCPs), aggregates built over the profiles of users that have visited discrete locations (i.e., venues). P ROFIL R endows users with strong privacy guarantees and providers with correctness assurances. In addition to a venue centric approach, we propose a decentralized solution for computing real time LCP snapshots over the profiles of colocated users. An Android implementation shows that P ROFIL R is efficient; the end-to-end overhead is small even under strong privacy and correctness assurances. Online social networks have become a significant source of personal information. Their users voluntarily reveal a wealth of personal data, including age, gender, contact information, preferences and status updates. A recent addition to this space, geosocial networks (GSNs) such as Yelp and Foursquare further collect fine grained location information, through check- ins performed by users at visited venues. Overtly, personal information allows GSN providers to offer a variety of applications, including personalized recommendations and targeted advertising, and venue owners to promote their businesses through spatio-temporal incentives, e.g., rewarding frequent customers through accumulated badges DISADVANTAGES OF EXISTING SYSTEM: Providing personal information exposes however users to significant risks.

- 2. PROFILR Toward Preserving Privacy and Functionality in Geosocial Networks First, we propose a venue centric P ROFIL R , that relieves the GSN provider from a costly involvement in venue specific activities. To achieve this, P ROFIL R stores and builds LCPs at venues. Furthermore, it relies on Benaloh’s homomorphic cryptosystem and zero knowledge proofs to enable oblivious and provable correct LCP computations. We prove that P ROFIL R satisfies the introduced correctness and privacy properties. Second, we propose a completely decentralized PROFIL R extension, built around the no tion of snapshot LCPs. The distributed P ROFIL R enables user devices to aggregate the profiles of co-located users, without assistance from a venue device. Snapshot LCPs are not bound to venues, but instead user devices can compute LCPs of neighbors at any location of interest. Communications in both PROFILR implementations are performed over ad hoc wireless connections. ADVANTAGES OF PROPOSED SYSTEM: Privacy preserving, personalized public safety recommendations and Privately building real time statistics over the profiles of venue patrons with Yelp Evaluate PROFIL R through an Android implementation. Show that PROFILR is efficient even when deployed on previous generation Smartphones. Contact: 9703109334, 9533694296 PROPOSED SYSTEM: accounts.
