Automatic recognition of an acoustic signature in underwater environments is an important and active field with multiple applications, one of which is vessel recognition. When a vessel moves through the sea, its engine and the cavitation generated by its propellers produce an acoustic wave of unique characteristics that allow for its individual identification. The problem of identification invo...

Biometric technologies are the primary tools for certifying identity of individuals. But cost of sensing hardware plus degree of physical invasion required to obtain reasonable success are considered major drawbacks. Nevertheless, the signature is generally accepted as one means of identification. We present an approach on signature recognition using face recognition algorithms to obtain class ...

Notions of signature and anomaly have formed the basis of useful methods in cyber defense, but even in combination provide only weak evidence for recognizing many events of interest. One can recognize many important events without requiring signatures of specific ways the events can take place and without treating every anomalous behavior as an event. We describe an approach to event recognitio...

In this paper, we present a novel face recognition algorithm based on the Point Signature a representation for free-form surfaces. We treat face recognition problem as a non-rigid object recognition problem. The rigid parts of the face of one person are extracted after registering the range data sets of faces having different facial expressions. These rigid parts are used to create a model libr...

Signature detection have a major issue in digital verification of signature without using online help. Handwritten signature is one of the most vastly accepted personal attributes for identity verification. The main area of research on signature verification is in the field of pattern recognition and image processing. Earlier different method of feature detection and classifications has been us...

In colonial birds, the recognition between parents and their offspring is essential to ensure the exclusivity of parental care. Although individual vocal recognition seems to be a key component of parent-chicks recognition, few studies assessed the period when the emergence of the vocal signature takes place. The present study investigated the acoustic cues of signaler identity carried in the b...

Commanding in robot teleoperation system can be done in several ways, including the use of sign language. In this paper, the use of centroid distance Fourier descriptors as hand shape descriptor in sign language recognition from visually captured hand gesture is considered. The sign language adopts the American Sign Language finger spelling. Only static gestures in the sign language are used. T...

In recent years it has been trying that with regard to the question of computational complexity of discrete logarithm more strength and less in the elliptic curve than other hard issues, applications such as elliptic curve cryptography, a blind  digital signature method, other methods such as encryption replacement DLP. In this paper, a new blind digital signature scheme based on elliptic curve...

The fact that the signature is widely used as a means of personal verification emphasizes the need for an automatic verification system because of the unfortunate side-effect of being easily abused by those who would feign the identification or intent of an individual. A great deal of work has been done in the area of off-line signature verification over the past few decades. Verification can b...

Handwritten signatures are one of the most socially accepted biometric traits. Signatures are commonly used in financial and legal agreements since more than a century. In education, signatures are used for attendance control, either to lectures or exams, but not for (automatic) authentication. With the rapid deployment of dynamic signature recognition, this technology is ready to be used for s...
