Abstract

Multi-user Software Authentication plays a vital role to authenticate and access software’s through online. Multi-user means multiple users are trying to access the software after purchasing through online with specified number of copies. Here copies indicate number of users to install and access the software through online process. In the existing work three tier process is used to authenticate multiple users and to validate users. In the three tier process, first tier is used to enter each user credentials for validation purpose. In the second tier user entered credentials are validated in the Tele- communication medium. After each user validation in the second tier, user registration details are sent to server for final authentication process. In this process each user is authenticated using three tier process which will take time and must posses Tele communication number. Tele communication framework is too expensive to implement. To overcome these problems a new two phase multi-user authentication framework is proposed. In the first phase, multi-user key registration process is proposed to each client registration verification and validation using proposed hash algorithm. In the second phase multi user activation code is verified to access software using proposed hash and encryption algorithm.
