SEAL (Secure Electronic Authenticity Layer) is an engine that generates verifiable, tamper-proof digital twins for emails, documents, and other digital assets using Web3 technologies such as IPFS and blockchain. It combines decentralized web applications with swarm-based data distribution to eliminate single points of failure, executing entirely on the user's device as an HTML5 dApp. The system protects digital information against manipulation, providing self-verifying credentials, cryptographic archival, and proof of authenticity across various devices and platforms without the need for centralized intermediaries.
The system utilizes an asynchronous data deployment model to manage resources, storing data fragments in a globally distributed file system. By recording cryptographic hashes on the blockchain, SEAL ensures that data remains unalterable and provides evidential value independently of centralized trust organizations. It integrates into existing workflows via REST APIs and extensions, supporting custom applications, record preservation, and lightweight electronic signatures.
