Blockchain based system for managing digital rights that would safeguard the privacy of digital contents, improves the fairness of transactions in digital copyright, and they free up digital copyright owners from administrative and time-consuming burdens. We started creating multi-authority ciphertext policy. The novel Attribute Based Encryption (MACP-ABE) scheme demonstrate it is indistinguishable from plaintext under an adaptively selected plaintext attack (ICPA) while maintaining high performance and security. When the ciphertext access policy need to be updated, the right holder can sell the copyright to multiple users by merging MACP-ABE with proxy reencryption. This agent is barred from accessing any data related to digital content. An Ethereum smart contract is used to perform a meaningful exchange of the decryption keys among the party requesting the rights and the party holding the rights. To further enhance fairness, data on digital rights are stored on another blockchain as a ledge, which significantly reduces public blockchain's storage overhead. Our system can provide ICPA security, thwart collusion attempts, and safeguard user privacy, according to a security study. Performance study demonstrates that our system can offer a plethora of functionality to satisfy a variety of user demands. The simulation results demonstrate how effective our method is in comparison to other existing schemes. Key Terms—Blockchain, proxy re-encryption, Digital Rights Management (DRM), multi-authority ciphertext-policy attributebased encryption (MACP-ABE).
