Privacy concerns of implicit secondary factors for web authentication
These implicit factors can help transform authentication from a binary decision problem (based on passwords alone) into a classification problem with a spectrum of possible decisions. For example, unusual values for implicit factors can be used as an indicator to detect merely suspicious logins for which additional explicit authentication actions (such as sending an SMS code) can be taken. Alte...
متن کاملImplicit Authentication for Mobile Devices
We introduce the notion of implicit authentication – the ability to authenticate mobile users based on actions they would carry out anyway. We develop a model for how to perform implicit authentication, and describe experiments aimed at assessing the benefits of our techniques. Our preliminary findings support that this is a meaningful approach, whether used to increase usability or increase se...
متن کاملPrivacy-Preserving Implicit Authentication
In an implicit authentication system, a user profile is used as an additional factor to strengthen the authentication of mobile users. The profile consists of features that are constructed using the history of user actions on her mobile device over time. The profile is stored on the server and is used to authenticate an access request originated from the device at a later time. An access reques...
متن کاملImplicit User Re-authentication for Mobile Devices
Portable computers are used to store and access sensitive information. They are frequently used in insecure locations with little or no physical protection, and are therefore susceptible to theft and unauthorized access. We propose an implicit user re-authentication system for portable computers that requires no application changes or hardware modifications. The proposed technique observes user...
متن کاملAn Approach for SMS Security using Authentication Functions
Asymmetric algorithm like Diffie-Hellman can be used to encrypt the SMS message in M-commerce or mobile banking system. Password key exchange protocol based on Diffie-Hellman key exchange algorithm allows users to exchange a secret key that can be used in message encryption. The security of this protocol can be increased by using the MAC (message authentication code) or hash function with the e...
