Preserving privacy in Cloud based applications using two-factor authentication (TOTP/WTP)

Abstract: Security and Privacy are the major concerns in the current trends of cloud environment. Securing the data and applications from the intruders, Hackers and internal attackers has become a challenge. On the other hand Preserving the privacy of users is also became a challenging task. Most of the cloud based service providers are providing high level of security but privacy of user is done only once at the authentication level. Many of the applications such as Salesforce.com, Google, and Amazon etc are using two factor authentications (TOTP). In this paper we have proposed secure cloud authentication architecture to deal with privacy in cloud applications, by using periodic two factor authentication in cloud systems.

Keywords: TOTP, WTP, Two-factor Authentication, Cloud Security.
