Polymer thick film sensors for embedded Smartcard Biometrics and identity verification
No full textSmartcards offer robust mechanisms for electronic demonstration of identity, and as a result are an increasingly important tool of e-commerce and information security. The identity of an authorised individual and their smartcard are, however, weakly bound and the presence of a legitimate and card-holder can not be assured. Hence, there is growing interest in the use of biometrics to strengthen the association between card and card-holder, although the emphasis has predominantly been to use external components such as sensors or processing elements. Such approaches expose the risk of eavesdrop and replay attacks, and because of this it is describe to incorporate all elements of an identity-verification system on-card. Potential discriminatory characteristics are limited to the measurable interactions between an individual and smartcard. Hence, the emerging field of biometrics is comprehensively reviewed for plausible mechanisms of demonstrating identity. Spatial finger characteristics such as fingerprints, finger-geometry and finger-crease pattern emerge as the most likely approaches. Sensors integrated onto smartcards are required to be mechanically flexible, robust and of low-cost, and such conditions are satisfied by a class of sensors known as polymer thick film (PTF). Piezoelectric and piezoresistive PTF pressure sensors are considered, and shown to exhibit sensitivity to loads applied elsewhere on the card. This effect renders the concept of using PTF pressure sensors to capture spatial finger characteristics infeasible. Nevertheless such sensing mechanisms can be exploited to capture temporal, rather than spatial interactions, and a novel approach to identity verification is proposed and demonstrated. This approach is based upon the pressure response of finger-taps, and an experiment involving 34 participants demonstrates significant discrimination between individuals. An investigation into suitable verification functions reveals that an equal error rate of 2.3% is achievable under controlled laboratory conditions. Necessary enrolment and verification algorithms are implemented on a typical smartcard platform, and found to execute within 3.1 and 0.12 seconds, respectively. Full compliance with the mechanical, computational, and economical constraints of a smartcard is consequently demonstrated.</p
Facing the Future: the Changing Shape of Academic Skills Support at Bournemouth University
No full textThis paper explores the potential impact of changes to higher education in England on student expectations, engagement, lifestyles and diversity, and outlines implications for the development of digital literacy within academic skills support at Bournemouth University (BU). We will investigate how tackling resource constraints with organisational change can also enable efficient, centralised provision of support materials that utilise networks to overcome the risk of fragmented support for digital literacy. We will also look at how changing delivery modes for support can accommodate changing student lifestyles whilst tackling a weakness of centralised support for digital literacy: that it can become detached from the student’s subject-focused academic practice. Finally we will explore how involving students in developing support can help us to face changes to student expectations and engagement whilst ensuring that materials are authentic and speak to learners in their own voice
Modeling liver fibrosis in rodents
No full textAnimal models of hepatic fibrosis provide a means to study the cell and molecular mediators of fibrosis in a serial manner during both progression and recovery. Several approaches to induction of fibrosis have been described. Of these, CCl4 intoxication in rats and mice is probably the most widely studied. In addition, the CCl4 model is the best characterized with respect to histological, biochemical, cell, and molecular changes associated with the development of fibrosis. CCl4 can be given intraperitoneally or by oral gavage; it induces zone III necrosis and hepatocyte apoptosis with associated hepatic stellate cell activation and tissue fibrosis. With repetitive dosing CCl4 can be used to induce bridging hepatic fibrosis (4 wk of twice-weekly dosing), cirrhosis (8 wk of twice-weekly dosing) and advanced micronodular cirrhosis (12 wk of twice-weekly dosing). In addition, for each of these models spontaneous recovery from fibrosis can be studied after cessation of dosing. Mechanistic studies using gene knockout and transgenic animals can also be established using CCl4. Together these models have provided unparalleled insights into the mechanisms underlying hepatic fibrosis

iButton Enrolment and Verification Requirements For The Pressure Sequence Smartcard Biometric
No full textWith the growing number of smartcard applications there comes an increasing need to restrict access to the card itself. In previous work we proposed the pressure sequence biometric, within which a biometric sensor is integrated onto the card in a low-cost and mechanically compliant manner. Using an off-card verifier we demonstrated reasonable discrimination between users. In this paper we consider a number of on-card verification schemes, the best of which offers an equal error rate of 2.3%. On-card computational time requirements were found to be 3.1 seconds for enrolment and 0.12 seconds for verification. Incorporating our implementation into an existing applet used 684 bytes of program space. Whilst data memory requirements are estimated to be 1400 and 300 bytes for enrolment and verification, respectively. These time and size requirements demonstrate our biometric as a practical proposition for the protection of smart cards. Experiments were performed with the iButton's Java Card platform
