how contentsign works

media captured and signed by phone
ContentSign establishes provenance using cryptography and blockchain. When content is created or uploaded, it calculates a unique fingerprint of the file using C2PA hashing algorithms. This fingerprint is chained on the blockchain with a signature and ownership records.
media is currently stored
nodle blockchain
Any changes result in a new fingerprint generated per C2PA. By tracing chained fingerprints on the blockchain, the full content history can be viewed to detect alterations. ContentSign also allows locally signing files, directly adding the initial fingerprint and signature to the blockchain without an intermediary.
media is validated
This cryptographic anchoring of C2PA-compliant fingerprints on the distributed ledger provides a tamper-proof record to verify provenance and authenticity of digital assets over time. It allows confirmation that content has remained unchanged since initial creation and signing using ContentSign's C2PA technology.

content authenticity initiative logo
Nodle partnered with Adobe's Content Authenticity Initiative (CAI) to bring the C2PA standard to NFTs for secure image provenance and verification. The team has developed SDKs that protect against manipulation via obfuscation and encryption.
C2PA stands for the Coalition for Content Provenance and Authenticity. The group was created to develop technical standards for certifying the source and history (or provenance) of media content to address the prevalence of misleading information online.
The coalition is composed of many industry leaders including Adobe, Arm, Intel, and Microsoft. Recently, Nodle joined Adobe's Content Authenticity Initiative and the C2PA working group to help define new industry standards for image and video attestation.
