Blockchain Messaging Integrity Verification

The patent introduces a blockchain as an intermediary distributed ledger that mediates between message senders and receivers. The blockchain records cryptographic hashes of messages and verification data, acting as a neutral third party that both sides can trust without needing to trust each other directly. This resolves the contradiction by providing high verification accuracy through cryptographic proof while managing complexity through standardized blockchain protocols and smart contracts.

The patent replaces traditional mechanical trust-based message verification systems with cryptographic verification based on blockchain technology. Instead of relying on centralized authorities or manual verification processes, the system uses cryptographic hashes, digital signatures, and blockchain consensus mechanisms to automatically verify message integrity and authenticity. This substitution provides higher verification accuracy while reducing operational complexity through automated cryptographic processes.

The patent applies preliminary cryptographic hashing and digital signing to messages before they are sent. The sender creates a cryptographic hash of the message content and signs it with their private key, embedding this verification data in the message header. This preliminary action allows the recipient to verify the message's authenticity and integrity before processing, enabling high spam detection capability while maintaining low false positive rates because legitimate signed messages are clearly identifiable.

The patent implements a feedback mechanism where message verification results (whether a message is signed and valid) are recorded on the blockchain and can be referenced for future verification. The system provides feedback to senders about message delivery status and to recipients about message authenticity, allowing continuous improvement of spam detection while minimizing false positives through learned patterns from verified legitimate messages.
