Systems and methods for deepfake-resistant data authentication
Disclosed herein is a quantum-based, deepfake resistant data authentication framework that provides read/write protections for electronic and/or digital content through quantum-based entanglement and steganographic techniques. In some implementations, the framework can identify who owns a digital asset to facilitate identification of digital content as being deepfake content and the takedown of the deepfake content. In some implementations, the framework can embed a watermark into the digital asset based on quantum principles, bind the watermark with physical properties of the digital asset, and entangle the embedded watermark (or qbit) with an entanglement bit (ebit) that is stored off-chain. In some implementations, the framework can introduce Gibbs artifacts into the digital asset as secondary identifiers. In some implementations, the framework can authenticate the digital asset based on the embedded watermark and/or the Gibbs artifacts subsequent to the digital asset being subjected to AI- and deepfake-based manipulations.
