LCHAIN: A Secure Log Storage Mechanism using IPFS and Blockchain Technology

Data security is a very important and crucial part of Cloud storage. Day by day, thousands operations function over the Cloud, verify logs generated from all transactions difficult. The attacker may temper or remove targeted attack traces on system with stealthy techniques. It required to maintain log trace back identify such tempering loss logs. Temper-proof storage challenging issue Cloud. To overcome issue, we propose strong secure using Blockchain technology IPFS. Detecting tracing due large volumes. We recommend usage its inherent feature immutability address tempering. present LChain which provides immutable tracing. helps yp create but also offers non-repudiation scalability. Smart contracts are used for efficient searching enhancing computational power.
