Blockchain key to real-world media validation – Nodle Cryptocurrency scrgruppen

Decentralized infrastructure network provider Nodle is working with the likes of Adobe and the Linux Foundation to use blockchain technology to authenticate real-world content captured by devices.

In correspondence with Cointelegraph, Noodle co-founder Garrett Kinsman outlined the company’s upcoming software development kit (SDK) for its ContentSign solution that will seek to prove the integrity of data from the moment it is captured using blockchain.

Nodle is bringing ContentSign to the Content Authentication Initiative, a project led by Adobe and the Linux Foundation, to create a future standard for media authentication.

As Cointelegraph previously explored, its main offering is a network that leverages smartphone Bluetooth connectivity to rent computing power, storage, and Bluetooth capacity to devices to scale IoT networks.

Kinsman says ContentSign is set up to form part of that puzzle to prove that a camera or physical device captured a particular piece of visual media and its corresponding metadata:

“The way this is done is by having a stamp proving that a real camera captured the video, the video is signed by the private key that only this camera knows, and the fingerprint of that video is published on the blockchain.”

This technology could be useful for a myriad of use cases, including journalism. Hypothetically, as Kinsman explains, a journalist could capture a video or photo of a breaking news event using a built-in ContentSign camera:

“While recording video, ContentSign ensures it is stamped and signed with a private key unique to that specific camera.”

The video fingerprint is then minted as a non-fungible token on the Nodle blockchain. The signature confirms that the content originated from a real source and was not manipulated or artificially created.

Kinsman adds that the current iteration has the service emulated on mobile through ContentSign’s SDK, but future implementations could mirror the technology found in cryptocurrency hardware wallets:

“In the future, the camera will include a secure element, similar to what you can find in a Ledger hardware wallet.”

Blockchain solutions like ContentSign could be crucial as artificial intelligence (AI)-generated content grows, increasing the need for solutions that differentiate between original and fabricated content.

“Blockchain, with its inherent characteristics of decentralization, transparency, censorship resistance, and immutability, provides an essential framework for establishing authenticity.”

Kinsman says ContentSign is being directly explored as a solution for the insurance industry to process claims accurately and fairly. ContentSign will ensure that the visual evidence provided for insurance claims is real and has not been manipulated or generated by artificial intelligence.
