Recent advances in wireless and computing technology have led to accelerated efforts to equip soldiers at the tactical level with sophisticated handheld communications devices to share situational awareness data. An important consideration is how to secure these devices, and how to ensure that the users of the devices have not been compromised. This paper presents the details of prototyping act...

In biometric authentication, iris recognition was shown to be one of the most accurate techniques. In unconstrained environment and capture conditions (e.g. with hand-held devices used outdoors), the iris image may be contaminated by noise and distortions which makes the iris segmentation and recognition process difficult. This paper presents a novel iris segmentation algorithm that addresses s...

Due to the intensive use of mobile phones for different purposes, these devices usually contain confidential information which must not be accessed by another person apart from the owner of the device. Furthermore, the new generation phones commonly incorporate an accelerometer which may be used to capture the acceleration signals produced as a result of owner's gait. Nowadays, gait identificat...

This is the second Innovations in Value Based Approaches to Diabetes Care Issue Brief in a series by the American Association of PPOs. This Issue Brief looks at “Patient-Centered Technology and Its Potential to Improve Diabetes Care.” It specifically examines the potential for technology to transform how patients manage and improve their health. While many recent innovations have emerged from t...

Mobile users are often faced with a trade-off between security and convenience. Either users do not use any security lock and risk compromising their data, or they use security locks but then have to inconveniently authenticate every time they use the device. Rather than exploring a new authentication scheme, we address the problem of deciding when to surface authentication and for which applic...

Biometric gait recognition is a well suited method for authentication on mobile devices as it is unobtrusive and concurrent. Hence, in contrast to PIN authentication it is no extra-effort for the user. The characteristic gait of a subject can be recorded using accelerometers which are nowadays already contained in many mobile devices. From this data biometric feature vectors can be extracted an...

-Now a day, e-commerce sites are very popular. Online shopping using wap enabled mobile phone has widely come into use. Debit and credit cards are used for secure etransaction. As the technology developed thief are also very smart, they stolen our detail from wap and use it. we present a model that can be used for secure transaction during using smart phone and give the features of smart phone ...

The role of smartphones in our life is ever-increasing. They are used to store and share sensitive data and to perform security critical operation online e.g. home banking transaction or shopping. This leads to the need for a more secure authentication process via mobile phones. Biometrics could be the solution but biometric authentication systems via mobile devices presented so far still do no...

Thewidespread use of mobile devices with Internet connectivity has resulted in the storage and transmission of sensitive data. This has heightened the need to perform reliable user authentication on mobile devices in order to prevent an adversary from accessing such data. Biometrics, the science of recognizing individuals based on their biological and behavioral traits, has the potential to be ...
