Mobile devices have found an important place in modern society, with hundreds of millions currently in use. The majority of these use inherently weak authentication mechanisms, based upon passwords and PINs, which can potentially be compromised and thereby allow attackers access to the device and its stored data. A need for stronger authentication is identified and the discussion considers the ...

ABSTRACT: Mobile ad-hoc network is an infrastructure less network. Continuous user authentication is an important prevention-based approach to protect the high security mobile ad-hoc networks (MANETs). Also intrusion detection systems (IDS) are also important in MANET to effectively identify malicious activities. Most previous work studies these two classes of issues separately. In this paper, ...

Mobile devices and technologies have become increasingly popular, offering comparable storage computational capabilities to desktop computers allowing users store interact with sensitive private information. The security protection of such personal information are becoming more important since mobile vulnerable unauthorized access or theft. User authentication is a task paramount importance tha...

Liveness detection is an important countermeasure against spoofing attacks on biometric authentication systems. In the context of audiovisual biometrics, synchrony detection is a proposed method for liveness confirmation. This paper presents a novel, text-dependent scheme for checking audiovisual synchronization in a video sequence. We present custom visual features learned using a unique deep ...

This article is focused on signature dynamics that is used for protection of qualified electronic signature functions and personal data on mobile platforms. The article presents a concept of the Trusted Pocket Signer (trustworthy PDA with integrated SmartCard used as Secure Signature Creation Device (SSCD)), role of biometrics within this concept, and major handwritten signature algorithm strat...

Gesture recognition is a challenging problem in the field of biometrics. In this paper, we integrate Fisher criterion into Bidirectional Long-Short Term Memory (BLSTM) network and Bidirectional Gated Recurrent Unit (BGRU), thus leading to two new deep models termed as F-BLSTM and F-BGRU. Both Fisher discriminative deep models can effectively classify the gesture based on analyzing the accelerat...

The use of mobile smart devices for storing sensitive information and accessing online services is increasing. At the same time, methods for authenticating users into their devices and online services that are not only secure, but also privacy and user-friendly are needed. In this paper, we present our initial explorations of the use of lock pattern dynamics as a secure and user-friendly two-fa...

With the increased popularity of touchscreen mobile phones, touch gesture behavior is becoming more and more important. Increasing demand for safer access in touch screen mobile phones, ancient strategies like pins, tokens, or passwords fail to stay up with the challenges conferred. Most of the current touch gesture authentication schemes facing problem with accuracy based on score classifiers ...

In this paper, we present some results on multimodality implementation resulting from the VINSI (“Vérification d’Identité Numérique Sécurisée Itinérante” for Secured Mobile Digital Identity Verification) French project. The VINSI handheld terminal allows identity verification in mobile conditions (airport gates) using two biometrics usable in future biometric passports (fingerprint and face). W...

Ubiquitous mobile devices like smartphones and tablets are often not secured against unauthorized access as the users tend to not use passwords because of convenience reasons. Therefore, this study proposes an alternative user authentication method for mobile devices based on gait biometrics. The gait characteristics are captured using the built-in accelerometer of a smartphone. Various feature...
