Blockchain key to verifying authenticity of real-world media — Nodle

As AI capabilities advance, certifying the validity of real-world photographs, video, and content may become dependent on blockchain technologies.Noodle, a decentralized infrastructure network provider, is collaborating with Adobe and the Linux Foundation to leverage blockchain technology to validate the authenticity of real-world content gathered by devices.

In an email to Cointelegraph, Nodle co-founder Garrett Kinsman described the company’s planned software development kit (SDK) for its ContentSign solution, which would use blockchain to certify the integrity of data from the moment it is captured.

Nodle is introducing ContentSign to the Content Authenticity Initiative, a collaboration between Adobe and the Linux Foundation to develop a future standard for media attestation. As previously reported by Cointelegraph, its core feature is a network that uses smartphone Bluetooth connectivity to rent processing power, storage, and device Bluetooth capability to widen the footprint of Internet of Things networks.

Nodle’s ContentSign technology is visualised capturing a real-world image that its data is cryptographically certified and published on a blockchain. According to Kinsman, ContentSign will be a piece of the puzzle in proving that a physical camera or device captured a certain piece of visual material and its related metadata: “This is accomplished by having a stamp that proves that a genuine camera captured the video, that the video has been signed by the private key only known to this camera, and that the video has been signed by the private key only known to this camera.”

The technique could be valuable in a variety of applications, including journalism. As Kinsman imagines, a journalist can capture video or images of a breaking news event using a camera equipped with ContentSign technology: “As the video is recorded, ContentSign ensures it is stamped and signed with a unique private key exclusive to that specific camera.”

The video’s footprint is then minted as a nonfungible token on the Nodle network. The signature verifies that the content is real and has not been modified or artificially manufactured. Kinsman adds that the service is now mimicked on a mobile phone using ContentSign’s SDK, but future versions may mimic technologies present in cryptocurrency hardware wallets: “In the near future, Blockchain solutions like ContentSign may become increasingly important as artificial intelligence (AI)-generated content expands, necessitating the need for solutions that discern between authentic and falsified information. “Blockchains, with their inherent characteristics of decentralization, transparency, censorship resistance and immutability, provide an essential framework to anchor authenticity.”

According to Kinsman, ContentSign is being investigated as a solution for the insurance industry to handle claims with accuracy and integrity. ContentSign will ensure that any visual proof presented for insurance claims is real and not manipulated with or generated by AI.
