Abstract
A method, apparatus and system for providing controlled access to data in a distributed computing environment include storing received data to be accessed via the distributed computing environment in at least one storage device, generating at least one integrity data structure identifying at least a storage location of at least a respective portion of the stored data, storing the generated at least one integrity data structure in a block of a blockchain, encrypting the at least one integrity data structure in the block of the blockchain, and selectively providing at least a portion of at least one decryption key for decrypting the encrypted at least one integrity data structure to enable access to the respective portion of the stored data for which the at least one integrity data structure is generated. Additionally, the stored data can be encrypted and a decryption key can be provided for decrypting the stored data.
