Decentralized infrastructure network provider Nodle has released the first version of its blockchain-based media authentication application called Click, which could prove useful in combatting artificially generated media and fake news.
As previously reported by Cointelegraph, Nodle has developed a software development kit (SDK) for its ContentSign solution, which cryptographically proves the integrity of data captured by mobile devices using blockchain technology.
The Click application supports the Coalition for Content Provenance and Authenticity (C2PA) and is a member of the Content Authenticity Initiative (CAI). The latter is a project led by Adobe and the Linux Foundation to create a future standard for media attestation.
In correspondence with Cointelegraph, Nodle CEO Micha Anthenor Benoliel said Click primarily serves photographers, citizen journalists, reporters, law enforcement, sports fans, paparazzi and content creators.

Given its association with C2PA and CAI, Benoliel adds that news and journalism are top use cases for the application, which is currently available on the Apple App Store while its Android version is in production.
The process of authenticating an image or video requires a user to capture the content using the Click app camera. The content is then signed and logged on Nodle’s underlying blockchain. It is then made available in the device’s local gallery and a Click’s public page, which includes attribution to the contributor.
Benoliel confirmed that images and videos authenticated via Click need to be taken with the Click app camera without interjecting other editing or generative artificial intelligence (AI) alterations, which removes the possibility of fake or generated images and videos being disseminated through the platform.
Stock image platforms like Getty and AFP remain a primary source for images and content for various industries, from newsrooms to advertising agencies. Benoliel said that Click envisages being a partner to these organizations as a “source of truth” for field-captured content:
“This puts the power in the hands of the content consumer when they approach Getty or AFP as they’d be able to see which images and videos are authenticated.”
