A Proposal of an Associating Image-Based Password Creating Method and a Development of a Password Creating Support System

In recent years, one of the most widely used authentication methods is a password-based authentication method. In this method, users are required to create a secure (i.e.\ difficult to crack) and memorable (i.e.\ easy to remember) password when they create one. Taking account of these two important requirements, a mnemonic phrase-based password has been proposed. However, it is easy to crack a password if the users adopt famous phrases (e. g.\ music lyrics, movie quotes) to create a mnemonic phrase-based password. In this paper, we propose an associating image-based password creating method to create a password which is difficult to crack and easy to remember. Furthermore, we propose and develop a password creating support system for our method.
