autism is a neurodevelopmental disorder originating from early childhood; nevertheless, its diagnosis is in older ages. in addition to heredity, environmental factors are also of great significance in the etiology of the disease. dermatoglyphic patterns, albeit varied, remain stable for a lifetime and yield a large number of patterns upon examination. studies have shown a significant associatio...

Fast and accurate ridge detection in fingerprints is essential to each AFIS (Automatic Fingerprint Identification System). Smudged furrows and cut ridges in the image of a finger print are major problems in any AFIS. This paper investigates a new online ridge detection method that reduces the complexity and costs associated with the fingerprint identification procedure. The noise in fingerprint...

In the field of wireless multimedia authentication unimodal biometric model is commonly used but it suffers from spoofing and limited accuracy. The present work pro-poses fusion features face fingerprint recognition system as an Improved Biometric Fusion System (IBFS) leads to improvement in performance. Integrating multiple traits performance improved thereby reducing fraudulent access.The pap...

background : the concepts of ‘intelligence’ and ‘intellectual performance’ though seem alike, but are different. intelligence assessment of an individual is technical, is done by the application of multiple, reliable and validated, iq (intelligence quotient) tests on the same individual in different settings (date, place and time). however, ‘intellectual performance’ (ip) has a reference only t...

We survey and evaluate popular audio fingerprinting schemes in a common framework with short query probes captured from cell phones. We report and discuss results important for mobile applications: Receiver Operating Characteristic (ROC) performance, size of fingerprints generated compared to size of audio probe, and transmission delay if the fingerprint data were to be transmitted over a wirel...

Location awareness of a user or a device has always been considered as a key element for enhancing network performance and improving user experience by enabling efficient mobility and innovative location-based services. In this paper, we present our proposal named WIFE (Wireless Indoor positioning based on Fingerprint Evaluation), a user-based location determination system which utilizes the in...

We consider the problem of remote authentication over a long range wireless network using large signature keys such as biometric samples (fingerprint, retinal scans etc.). Because of the large size of these keys, and continual need for authentication, considerable power and bandwidth is consumed by such processes. We show that by using the concept of a holographic proof, it is possible to signi...

In fingerprint-based wireless positioning, a high number of wireless access points solicits feature reduction to obtain a compact radio map for accurate real-time positioning. Although principal component analysis (PCA) can be used to reduce dimensionality, PCA is computationally expensive. Additionally, PCA maps the data to a new space where physical meaning of the original features is lost. P...
