Abstract : Biometric data is a technology that users or workers use and saves a lot of time. This technology helps people to keep things, data, and information more safe. There are several types of biometric such as fingerprints scan, iris scan, palm scan, face scans and many more. Users no longer need to remember passwords or pin codes because of this technology. Users just have to scan their fingers or palm, face or eyes to unlock devices and this system is way more secure than any other systems. Though it is a high cost system, organisations can trust on this system because no one can easily hack this technology as every person has different characteristics. Passwords, pin codes, pattern locks can be easily hacked but hacking someone’s fingerprints or iris scan is quite impossible. Still hackers can hack this technology sometimes. Mainly voice commands get hacked easily because anyone can record a user's voice without consent. In that case, users have to be more careful about personal things and should not share single information with anyone
