The Design to Manage Online and Off-Line Block-Chain Based Mechanism for Community Analysis and Privacy Preserved Information Exchange

Project Details


The prosperity of block-chain based activities shows that people have accepted the de-centralized platform. Such platforms encourage complete local authority. With this kind of trust, many services and consumption behaviors have been operated on those platforms, and more broad applications are anticipated.We attempt to facilitate data exchange, for better understanding of the overall community, with the trust in the block-chain environments. The first issue is to strengthen the privacy protection. Unfortunately, as differential privacy prompted, private data can be improperly revealed, by comparing and putting together pieces from different sites.This problem cannot be efficient solved by purely local managements, with different protecting policies running on each cites.To offer feasible solution, we have studied three related fields: 1.Institutional Research, data usually needs to be integrated from different organization before analysis tasks. This provide us a realistic case to understand the requirements. 2. Differential privacy, a branch of statistic research that most people adapted for privacy protection. 3. Smart contract, a programmable service enable data exchange and management on top of block-chain platform.After preliminary investigation, it is feasible to implement differential privacy mechanism, and collaboratively contribute integrated analysis, in smart contracts. Putting our attentions to several research fields in the meantime, we are confident to bring positive influences for data exchange confidence, integrated techniques, and flexible applicability.
