Biometrics & Password Systems Flashcards

All 3 cards in this deck

Give two ways a password system can be made more secure.

Any two of: lock the account after a set number of wrong attempts; require long passwords that mix letters, numbers and symbols; make users change their password at regular intervals; ask for a second factor, e.g. a code sent to the user's phone; at each login, ask for only a few characters of the password, picked at random.

What are biometric security measures?

Measures that identify a person from a unique physical feature, such as a fingerprint, face or iris. The scan is compared with reference data stored when the user set it up.

Why are biometrics well suited to mobile devices?

Any two of: phones have built-in fingerprint sensors and cameras; unlocking is quick, so users are less likely to switch the lock off; a fingerprint or face cannot be forgotten, guessed or watched over someone's shoulder like a PIN.
