VERIFICATION Act of proving or disproving the correctness of a system with respect to a certain formal specification. 2 methods are : 1. User identification 2. Processed object

Pin number ********* Password ********* something you know 1

2 something you have Smart Card ATM Card Credit Card Security Token

Pin number Password Something you know Something you have

Static Password Dynamic Password Something you have Something you know SECURITY TOKEN A security token is a small handheld device that dynamically generates and displays a password.

CONCLUSION 12 ways to protect privacy. 2 commonly authentication methods are : – Biometric device (something you are – part of user’s body) Fingerprint recognition, facial recognition, hand geometry scanning, iris scanning, retinal scanning, voice recognition, signature verification system. – Callback system Used in the bank operation and business transaction.

CONCLUSION 2 commonly verification methods are : – User identification (something you know – have to remember) Pin number or password – Possessed object (something you have – an object) Atm card, credit card, key, security token and smart card
