PersonaIA: A Lightweight Implicit Authentication System Based on Customized User Behavior Selection

Implicit Authentication through Learning User Behavior

Users are increasingly dependent on mobile devices. However, current authentication methods like password entry are significantly more frustrating and difficult to perform on these devices, leading users to create and reuse shorter passwords and pins, or no authentication at all. We present implicit authentication authenticating users based on behavior patterns. We describe our model for perfor...

Game-Based Cryptanalysis of a Lightweight CRC-Based Authentication Protocol for EPC Tags

The term "Internet of Things (IoT)" expresses a huge network of smart and connected objects which can interact with other devices without our interposition. Radio frequency identification (RFID) is a great technology and an interesting candidate to provide communications for IoT networks, but numerous security and privacy issues need to be considered. In this paper, we analyze the security and ...

A Lightweight Binary Authentication System for Windows

The problem of malware is greatly reduced if we can ensure that only software from trusted providers is executed. In this paper, we have built a prototype system on Windows which performs authentication of all binaries in Windows to ensure that only trusted software is executed and from the correct path. Binaries on Windows are made more complex because there are many kinds of binaries besides ...

Speaker Verification Based on User-Customized Password

Implicit 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...
