Towards Contractual Agreements for Revocation of Online DataContractual Agreements for Revocation of Online Data • March 5th, 2019
Contract Type FiledMarch 5th, 2019perspective by examining how contractual agreements can be applied to create incentives for providers to conform to expiration regulations. Specifically, we propose a protocol to automate the handling of data revocation. We have implemented a prototype smart contract on a local Ethereum blockchain to demonstrate the feasibility of our approach. Our approach has distinct advantages over existing proposals: It can deal with a wide spectrum of revocation conditions, it can be applied retroactively after data has been published, and it does not require additional effort for users accessing the published data. It thus constitutes an interesting, novel approach to data revocation.
