title: What is the purpose behind the personalized security image often used on banking websites?
body: <p>Many banking websites have you select your own security image when creating your account.  For subsequent log ins the image is displayed along with a caption, if you do not see the image and caption you chose, you are instructed not to log in.</p>
  
  <p>What is the purpose of this added step, which type of attacks does it protect against?</p>
  
  <p>Thanks!</p>
