SmartData: Smart Crowdsourcing Data Management with Blockchain

An innovative approach to manage large scale geo-data on immutable data storage to ensure data credibility, traceability and auditability.

For smart city applications, the ability to validate and verify such data is challenging, particularly where there are different users updating on the same data and there is no central authority to guarantee the credibility of the data. For example, a crowdsourced smart city model requires cumulative updates from different users. As large amounts of data are changed from time to time, it is difficult to verify and audit the changes. Users may also experience long waiting time when querying data.

This invention facilitates large collections of data creation, manipulation and storing among different users, and provides a fast and reliable way to acquire crowdsource data. It also reduces the waiting time to load a cumulative updated Geo-data from a server.

Key technologies:

  1. Systems and methods to provide geo-data management
  2. A collaborative rating mechanism to help users to determine the credibility of the data
  3. A smart merging mechanism to avoid delays in queries for the cumulative updated data
