VeraSnap unleashes CPP to cryptographically chain-kill fake news: Merkle trees, LiDAR scans, and TSA stamps prove your photo exists—but not if it's bullshit

The Capture Provenance Profile (CPP) is a cryptographic standard for verifying the authenticity of digital media, developed by the VeritasChain Standards Organization. CPP version 1.5 provides a comprehensive framework for establishing the provenance of digital content, including photos and videos. When a user captures a photo with a CPP-compliant application like VeraSnap, the device generates a unique digital fingerprint, or "EventHash," which is then linked to a Merkle tree, a data structure that allows for efficient verification of the content's integrity. The Merkle root is then anchored to a Timestamping Authority (TSA), which provides an independent, third-party verification of the content's existence at a specific point in time. This triple binding of EventHash, Merkle root, and TSA token creates a robust and tamper-evident provenance record, allowing anyone to verify the authenticity of the content. The CPP standard has significant implications for the fight against fake news and misinformation, as it provides a mathematical framework for evaluating the trustworthiness of digital media. With CPP, fact-checkers and viewers can independently verify the provenance of digital content, reducing reliance on trust and promoting a more transparent and accountable digital landscape.
