Blockchain key for verifying the authenticity of real media

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

In correspondence with Cointelegraph, Nodle co-founder Garrett Kinsman outlined the company’s upcoming software development kit for its ContentSign solution, which will seek to prove data integrity from the point of capture using blockchain.

Nodle brings ContentSign to the Content Authenticity Initiative, a project it has joined and is led by Adobe and Linux Foundation to create a future standard for media attestation.

Nodle is developing a variety of blockchain-based technologies aimed at capturing and authenticating real-world data. As Cointelegraph has previously explored, its main offering is a network that uses Bluetooth connectivity for smartphones to rent computing power, storage, and Bluetooth capabilities from devices to expand the footprint of IoT networks.

Kinsman says ContentSign will be part of this puzzle as a means to prove that a physical camera or device captured a specific piece of visual media and its associated metadata.

“The way this is done is by having a stamp that proves that a real camera captured the video, the video is signed with the private key known only to this camera, and a footprint of this video is published on a blockchain . ”

The technology could be useful for a wide range of use cases, including in the field of journalism. As Kinsman explains hypothetically, a journalist can take video or photo of a major news event using a camera embedded in ContentSign technology:

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

The video’s footprint is then minted onto the Nodle blockchain as a non-fungible token. The signature confirms that the content comes from a genuine source and has not been manipulated or artificially generated.

Kinsman adds that the current iteration emulates the service on a mobile phone via ContentSign’s SDK, but future implementations could mirror the technology found in cryptocurrency hardware wallets:

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

Blockchain solutions similar to ContentSign could be critical as AI content generation increases, creating the need for solutions that distinguish between authentic and fabricated content.

“Blockchains, with their inherent features of decentralization, transparency, censorship resistance and immutability, provide an essential framework to anchor authenticity.”

Kinsman says ContentSign is immediately being explored as a solution for the insurance industry to process claims with accuracy and integrity. ContentSign ensures that the visual evidence submitted for insurance claims is genuine and has not been tampered or AI-generated.
