Capture App
Capture, by Numbers Protocol, is a Web3 camera application designed to combat digital fraud and establish verifiable provenance for photos and videos. It functions as the primary creation tool for the Numbers Protocol network, allowing users to generate digital media that is authentic, traceable, and secure from the moment of creation. The app is targeted at content creators, photographers, journalists, and anyone concerned with the integrity and ownership of their digital work in an age of AI-driven misinformation.
When a user takes a photo or records a video with the Capture App, it automatically embeds the content with rich, tamper-proof metadata. This includes critical information such as the creator's identity, a secure timestamp, and geolocation data. This entire package is then registered on a blockchain, creating an immutable "birth certificate" for the asset. This process adheres to the C2PA (Coalition for Content Provenance and Authenticity) standard, ensuring a high degree of trust.
This "Capture-secured" content provides a clear and verifiable history that travels with the asset, allowing anyone to confirm its origin and view any subsequent edits. Furthermore, the app provides a seamless, one-click process for users to mint their verified content as non-fungible tokens (NFTs) on various blockchains.

W3C Decentralised Identifiers (DIDs) are a new type of globally unique identifier designed to enable verifiable, decentralised digital identity. As a formal web standard published by the World Wide Web Consortium (W3C), the DID architecture is a foundational component for building a more secure and user-centric internet.
Unlike traditional identifiers such as email addresses or usernames, DIDs are not tied to any centralised registry or company. This means that individuals and organisations can create and control their own identifiers, giving them "self-sovereign" control over their digital identities. The core of the system is the DID Document, a JSON file that contains the cryptographic keys and service endpoints associated with a DID. This document is stored on a distributed ledger or other decentralised network, allowing for secure and verifiable interactions.
The Hedera Consensus Service (HCS) is used to create a tamper-proof and auditable log of all DID-related events, such as creation, updates, and revocation.

The Content Authenticity Initiative (CAI) is a cross-industry community founded in 2019 by Adobe, The New York Times, and Twitter to combat digital misinformation and provide a verifiable layer of trust for online content. With a rapidly growing membership of over 4,000, the CAI brings together technology companies, media organizations, and civil society to develop open-source tools and standards that promote transparency and give creators credit for their work.
The primary service of the CAI is the development and promotion of Content Credentials, an open-source technology that functions like a "nutrition label" for digital media. This system allows creators to attach secure, tamper-evident metadata to their content, creating a verifiable record of its origin, authorship, and edit history. This provenance data is cryptographically signed and remains with the content as it is shared and modified. The technical specifications for Content Credentials are developed by the Coalition for Content Provenance and Authenticity (C2PA), a standards development organization co-founded by Adobe.
