SMART CONTRACT-BASED FREE PRIVILEGE-PASS AUTHENTICATION SYSTEM FOR INDIAN RAILWAY USING PERMISSIONED BLOCKCHAIN

Abstract

Indian Railways conducts one of the world's largest recruitment drives annually across several railway zones. Each railway
employee gets free and discounted travel everywhere in India. The corresponding railway zone issues free Privilege
Pass/PTO certificates. Each employee benefits. E-Pass Verification ensures the authenticity of a railway authority's
certificate. E-Pass verification affects deal authenticity. Illegals can benefit from discarded data. We proposed implementing
and issuing E-Passes to railway employees using Blockchain Technology to solve this problem of forged E-Passes. It is
one of the latest technologies that provide provenance and tamper-proof security. To verify that data’s fidelity, we use a
blockchain hash affirmative method. The blockchain's prominence aids in the abolition of bogus E-passes. In this research
article, the author used a permissioned public blockchain platform known as Hyper-Ledger for E-Pass authentication and
verification. The system is more secure, and only legitimate railway employees verified by the CRIS (Centre for Railway
Information Systems) system can join the network. The authenticity of information can be ensured by verifying distributed
ledger technology against the hash in the blockchain at any moment.
