Tamper-proof Signalling System
The Indian Institute of Technology, Kharagpur, is developing a tamper-proof signalling system based on blockchain technology for the Indian Railways.
Embedded with enhanced safety measures.
The new system would complement the existing Data Logger, which is considered the ‘Black Box’ of rolling stock.
Blockchain is a system of recording information which cannot be tampered, hacked or manipulated.
The Blockchain technology was being widely used in cryptocurrency and banking transactions.
The focus was to make the live movement of trains available for Station Masters, Section Controllers, Signal Engineers and others with all logs.
The new system would provide enhanced data integrity, transparency and security.
It would enable secure data sharing among stakeholders, automate processes with smart contracts and create tamper-evident audit trails.
The system would complement the Data Logger which was limited by its centralised storage facility, lack of tamper-evident data, and limited access control.
The new blockchain system would address these limitations by storing data in a distributed ledger, using cryptography.
