Blockchain-Enhanced Watermarking for Cloud-Based Content Authentication
Birendra Kumar Saraswat, Prem Chand Vashist · 2025
In this chapter, the problem of content authentication in cloud computing is addressed, and a Blockchain-Enhanced Watermarking (BEW) system is proposed. With digital assets now stored in the cloud, access and sharing become even more challenging. With content no longer sitting on a server on your premises, how do you ensure that it has come from a trusted source and that it hasn't been altered? Conventional watermark methods safeguard ownership but have an insufficient ability to trace back, are impossible to prevent distortion, and lack an encryptable digital proof for the data in open networks. The BEW utilizes resilient digital watermarking techniques, along with permissioned blockchain, to maintain an indelible, decentralized record of watermark data.
