 * Explain** why biometrics is becoming a popular way of identifying people by governments:

Biometrics are becoming a very popular way of identifying people by governments because they seem to be be a reliable source for authenticating yourself, whether you are in a riot or entering an office, through biometrics the government can verify if you are who you claim to be. This decreases the range of error that the common authentication methods use (username/password) thus giving the government the ability to identify more accurately its citizens, not only the "normal ones" but people with a criminal record or suspects.

Another reason for the popularity of biometrics is that the government is able to know who has entered to a bank, so if the bank suffers a robbery, the government is able to know who was the last person who entered to the bank and may lead to the person who did the robbery.


 * Describe** the main steps involved in biometrics use:

First is the enrollment part, where your physiological/behavioural data is collected and stored by a computer and stored in a database for the first time. Secondly is the matching aspect, here is when later you re-enter your data in a specific device, this device collects the data and compares it with the one on the database and if it matches it gives you access.
