Déjà Vu

 

In this section, we present a solution to address the shortcomings of passwords discussed in the previous section. In particular, we aim to satisfy the following requirements:

• The system should not rely on precise recall. Instead, it should be based on recognition, to make the authentication task more reliable and easier for the user.
• The system should prevent users from choosing weak passwords.
• The system should make it difficult to write passwords down and to share them with others.

 
• System Architecture
• Attacks and Countermeasures
• Sample Applications
