Multi-tiered Framework for User Authentication Based on

With the tremendous development in information technology, the use of technology has become in most areas, and it became the most procedures and electronic transactions, for example: electronic banking and social networking. All these leds to the presence of a huge amount of data is one of the privacy for the user, and it must protected by assigning a password to gain unauthorized access to that data, because the Privacy and confidentiality are the most important elements of information security, and it must be for each user to assign a password to gain access to his own data safely and does not even provide an opportunity for illegal access to data. Usually When the user wants to set a password putting in his mind some of the following considerations: Can be alphanumeric password; i.e. (containing letters, numbers and sometimes both), to be an easy password; in order to remember it later, can be semantic or meaningful password; i.e. (family, wife, children and care names) and can be date password; i.e. (date of birth, date of marriage and date of joining job). All these considerations indicates that the previous password ware sat by the user can be easly known by attackers, because they use software and the dictionaries for the purpose of finding a huge sense of the words to detect passwords. The main goal of a good authentication system is to provide a multilayered of secure password called Multi-tiered Framework for user authentication which based on multimedia password rather than alphanumeric password. This paper presents a Multi-tiered Framework of having an effective authentication system, which provides strong password hard for the attackers to guess and easily remembered graphical passwords for the users with a high level of security. On the other hand, is to reduce the guessing attacks as well as encouraging users to assign a difficult password to guess by the attackers and easy for him to remember it.
