Authentication using graphical password in cloud

Recently, cloud computing is the most popular term among enterprises and news. The concept comes true because of fast Internet bandwidth and advanced cooperation technology. Resources on the cloud can be accessed through Internet without self-built infrastructure. Enterprises can reduce their maintain cost and put more resource into marketing and research. Unfortunately, the infrastructure of cloud computing is built on Internet, and will encounter all the risk of Internet. To decrease the risks, an authentication mechanism is the possible solution. However, traditional alphanumeric password authentication mechanism is not secure enough. A secure authentication mechanism using graphical password should be proposed in this paper for improving traditional authentication mechanism and let users access cloud services securely.
