Data stored on a cloud server isfaced a number of security problems and threat issues in the user authentication and access control mechanisms. Protecting sensitive business data in the cloud is more valuable because it should be accessed only by the authenticated personnel. The implementation of effective security mechanisms willraise the level of security competence and allows only authenticated individuals by verifying various security parameters given by humans. Sometimes the data is stolen and misused in cloud server in the previous secure authentication methods. Normally, encryption methods are used in the security mechanisms. Another method of implementing security mechanism in the cloud server is by using MAC address. This paper discusses how a MAC address is more beneficial and result-oriented than previous recognition systems.
