Data Integrity and Secure Storage

Ensuring data integrity is a crucial aspect of IoT applications. AIoTChain leverages blockchain and distributed storage to protect IoT data from tampering and privacy breaches.

Technical Approach:

1. On-Chain Hashing + Off-Chain Storage

   • Lightweight Storage: Since IoT devices generate vast amounts of data, AIoTChain adopts a hash-on-chain, data-off-chain storage model to reduce blockchain load while improving efficiency.

   • Decentralized Storage (IPFS/Filecoin/Arweave): Integrating decentralized storage solutions to enhance reliability and censorship resistance.

2. Tamper-Proof Data Verification

   • Timestamps and Hash Encryption: IoT data is automatically time-stamped and hashed using SHA-256, ensuring immutability.

   • Zero-Knowledge Proofs (ZKP): Allows privacy-preserving data verification.

Use Cases:

• Supply Chain Tracking: Ensures trust in logistics and cold-chain transport data.

• Smart Healthcare: Protects patient data against leaks and modifications.

• Connected Vehicles (V2X): Secures autonomous vehicle communication to prevent cyberattacks.
