This document proposes a Blockchain Secured Biometric Access System (BSBAS) that uses blockchain technology to securely store biometric data and reduce the risk of identity fraud. The system works as follows:
1) A user registers by submitting biometric data (e.g. fingerprint, facial scan) which is converted into a binary format and hashed.
2) The hashed biometric data is stored immutably in a blockchain.
3) When the user wants access, their biometric data is hashed and compared to the hashed data stored on the blockchain. If it matches, access is granted.
Storing biometric data on the blockchain makes it more secure and reduces the risk of biometric
