Abstract

AbstractThis research produces multilevel authentication used in sensitive applications that contain sensitive levels of security and the maintain confidential data. Proposed method divides the system to variety of levels and tests users against different authentication methods for each level these levels are further subdivided into more secure sublevels. Each of these levels has its privileges and data that are managed by the administrator called Identity Manager (IM) who has the full responsibility and authority to decided transfer the user from one level to a higher level, or stay at the same level. The decision of transition is done by allocate different weights for each method achieved after a series of tests, the Director of identity must issue a report describing the findings and resolution to the activity of all users. This technique gives only the required privileges to selected users who set their permissions to enter the system. The multi-level protection methods include (password, multiple questions, cutting (Hash), RSA, and DES) system was tested on a set of users, and has high security level.
