Over the last two decades, in the field of secure communication and financial on-line applications, we have witnessed an explosive growth in biometric personal authentication systems which are covenant with a measurable physical characteristic or behavioral trait. On-line refers to making use of the time functions of the signing process. Verification of(More)
Current network based authentication applications require simple robust methods which are faster and does not choke the bandwidth. Minimal features are considered using subpattern analysis which leads to less response time in a real time scenario. Certain subsections of signature vary in a genuine case subvailable online 22 December 2010 ff-line signature(More)
Biometrics, which refers to identifying an individual based on his or her physiological or behavioral characteristics, has the capabilities to the reliably distinguish between an authorized person and an imposter. The Signature recognition systems can categorized as offline (static) and online (dynamic). This paper presents Surf Feature based recognition of(More)
—Hand written object [HO] verification is the process used to recognize an individual, is intuitive reliable indicator which can be character recognition, handwriting verification, style classification, shape recognition and signature recognition. This paper discusses the trajectory generation [TG] methods, as novel methods to deal inter-class and(More)
In online applications, there is a foreseeable explosive growth in biometric personal authentication systems which are covenant with a measurable behavioral trait. Hand written object [HO] verification is the process used to recognize an individual, which is intuitive reliable indicator. Verification of a HO as a biometric modality still is a challenging(More)
In Heterogeneous systems, Vertical Handoff calculations (VHAs) used to permit mobile terminals (MT) to keep up the system association when versatile hub switch starting with one remote system then onto the next one. The Vertical Handover Decision is NP-Hard issue, thus assessment of all VHA is imperative perspective while working with Vertical Handoff(More)
The next generation wireless systems will support heterogeneous traffic with seamless mobility. A single network alone cannot cope up with such heterogeneous requirements. Hence it is desirable to interoperate between diverse and complementary radio access technologies (RATs).In such system, user will switch between different radio access technologies(More)
