A Thorough Study on Privacy preserving Crowdsourcing platform On blockchain

Computer Engineering

The Crowdsourcing approach has been highly useful and extremely popular in the recent years. The reason for this immense popularity is the improvement in the communication capabilities that help coordinate the workers effectively. This is since the platform has aided in the completion of extremely complex tasks. Crowdsourcing is a method of bringing together a big group of individuals or a crowd, to complete the task. This enables the work to be completed successfully, which would have not been feasible if the crowdsourcing approach had not been implemented. However, the majority of crowdsourcing methods have flaws. On the worker's side, there are increasing issues with unfinished or abandoned jobs. In addition, task uploaders have complained about receiving insufficient pay. Both situations result in a loss of confidence among the crowd intelligence system's many players. As a result, this literature survey paper utilizes the previous researches which describe a crowdsourcing system as a viable and safe resolution to these problems. The Reverse Circle Cipher Encryption and Entropy Estimation algorithms, as well as Decision Tree and the distributed Blockchain infrastructure, are helpful in achieving the prescribed goals in this literature survey paper.
