Systems and methods for providing secure data access control using distributed ledgers

Techniques providing secure data access control mechanisms using distributed ledgers are disclosed. The method includes receiving information 902 related to customers via a secure application programming interface and encrypting 904 the received information using a cryptographic algorithm. The encrypted information is transmitted 906 to a cloud service platform and thereafter categorized 908 into sensitive and non-sensitive data. Further, the cloud service platform is configured to record the encrypted non-sensitive data in a public blockchain 910 and encrypted sensitive data in a private blockchain 912 by executing a smart contract. These blockchain transactions are accessible by the customers and the vendors. Furthermore, a communication protocol is established 914 between the customers and the vendors. The smart contract is executed 916 based on an approval from one of the one customers to allow one of the vendors to view at least a sub-set of the sensitive data related to that customer.
