Offline signature identification and verification systems encounter several challenges such as the diversity of signatories and the limited number of references. To address these problems we propose a new writer-independent system for signature identification and verification. Besides, a new feature generation scheme is proposed by using the Histogram Of Templates (HOT). The identification and verification...
Online Signature Verification is one of the most feasible biometric authentication techniques and is being widely researched upon. In this paper, some of the popular approaches towards Online Signature Verification are reviewed, and an abstraction of the general process involved in these approaches has been proposed. The most critical area in this process has identified to be that of feature selection...
Doodle-based graphical passwords represent a challenging scenario due to their high variability and the tendency to be graphically simple. Despite this, doodle-based authentication using touch screens is a promising lightweight user verification method. Several works have been published in this field, although they report in general experimental verification results over small and private databases...
