SYSTEMS AND METHODS FOR PROVIDING SECURE DATA ACCESS CONTROL USING DISTRIBUTED LEDGERS

摘要

Techniques for providing secure data access control mechanisms using distributed ledgers are disclosed. The method includes receiving information related to customers via a secure application programming interface and encrypting the received information using a cryptographic algorithm. The encrypted information is transmitted to a cloud service platform and thereafter categorized into sensitive and non-sensitive data. Further, the cloud service platform is configured to record the encrypted non-sensitive data in a public blockchain and encrypted sensitive data in a private blockchain by executing a smart contract. These blockchain transactions are accessible by the customers and the vendors. Furthermore, a communication protocol is established between the customers and the vendors. The smart contract is executed based on an approval from one of the one or more customers to allow one of the vendors to view at least a sub-set of the sensitive data related to that customer.
