Nodle, in collaboration with Adobe and the Linux Foundation, seeks to use blockchain technology as an instrument to authenticate captured content from the real world.
In correspondence with Cointelegraph, Nodle, co-founder Garrett Kinsman described the company’s forthcoming software development kit for its ContentSign solution, which will use blockchain to verify the integrity of captured data.
Nodle is contributing ContentSign to the Content Authenticity Initiative, an Adobe and Linux Foundation-led effort to develop a future standard for media authentication.
Nodle is developing a multitude of blockchain-based technologies for the capture and validation of real-world data. As previously discussed, its primary offering is a network that rents out computing power, storage, and Bluetooth capability of devices to expand the footprint of IoT networks.
Kinsman says that ContentSign is set to form part of this puzzle to establish that a physical camera or device has captured a specific piece of visual media and its corresponding metadata.
“The way this is done is by having a stamp that proves that a genuine camera has captured the video, the video has been signed by the private key only known by this camera, and a footprint of this video has been published to a blockchain.”
The technology could be beneficial for a variety of applications, including journalism. Kinsman explains hypothetically that a journalist can capture video or images of a live 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.”
On the Nodle blockchain, the footprint of the video is then minted as a non-fungible token. The signature verifies that the content comes from an authentic source and has not been altered or generated artificially.
Kinsman adds that the service is replicated on a mobile phone through ContentSign’s SDK in the current iteration, but future implementations could resemble 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.”
As the production of AI-generated content increases, the need for solutions capable of distinguishing between authentic and fabricated content will increase, making blockchain-based solutions similar to ContentSign crucial.
“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 explicitly considered a solution for the insurance industry to process claims accurately and honestly. ContentSign verifies that submitted visual evidence for insurance claims is authentic and has not been tampered with or generated by artificial intelligence.
