A Crowdsourcing Information Obtaining Scheme Aiming at Senior Netizens Based on Blockchain
Yanlin Qin, Xueguang Zhou, Guoheng Wei · Journal of Sensors · 2022
Senior netizens play a unique role in crowdsourcing information obtaining, but the traditional crowdsourcing information obtaining scheme based on intermediary platform cannot satisfy the senior netizens’ strong reliability on anonymity. Malicious intermediary platform may leak out the privacy information of both parties. Data stored in intermediary platform may be intercepted, tampered, and fraudulently used by attackers, so smooth crowdsourcing information transactions cannot be ensured. In order to achieve secure and reliable crowdsourcing information obtaining, blockchain technology with decentralization and nontampering was used to propose a crowdsourcing information obtaining scheme, which is independent on intermediary platform. During processes of requirements releasing, information submitting, and rewarding, privacy protection techniques were used to preserve the anonymity of participants and confidentiality of data. Compared with the existing protocols, the proposed scheme has obvious advantages in privacy protection.
