    Speaking Test
     
    There are numerous databases that contain personal, but public, information about 
    individuals. Today much of this data is available online.

    How do you feel about your personal information being contained in databases that 
    other individuals can access or that might be breached via the Internet? 

    Do you mind that anyone with an Internet connection might be able to find out how 
    much you paid for your house, if you are married, where you live, and other personal 
    information? 
    It is becoming increasingly common for biometric devices to be used to grant or deny access 
    to facilities, as well as to identify consumers for financial transactions. In order to facilitate this, 
    some data about each participant’s biometric features must be stored in a database.

    How do you feel about your biometric characteristics being stored in a database?

    Does it depend on whether the system belongs to your bank, employer, school, or the 
    government? 

    Because biometric features cannot be reset, are you at risk using a biometric ID 
    system? Why or why not?
