Abstract:

Data is becoming a new type of factor of production.How to compliantly and audibly circulate data among multiple parties is very important for data value formation.A novel data circulation paradigm, namely data tenancy, was proposed from the perspective of privacy preservation and data utilization.The motivation of data tenancy was discussed, and five requirements that data tenancy should satisfy were identified.Finally, a secret sharing-based data tenancy technique was proposed.

Key words: data circulation, secret sharing, data tenancy, privacy preservation
