TLDR
Previous work in the field of signature and writer identification is presented to show the historical development of the idea and a new promising approach in handwritten signature identification based on some basic concepts of graph theory is defined.Abstract:
Handwritten signature is being used in various applications on daily basis. The problem arises when someone decides to imitate our signature and steal our identity. Therefore, there is a need for adequate protection of signatures and a need for systems that can, with a great degree of certainty, identify who is the signatory. This paper presents previous work in the field of signature and writer identification to show the historical development of the idea and defines a new promising approach in handwritten signature identification based on some basic concepts of graph theory. This principle can be implemented on both on-line handwritten signature recognition systems and off-line handwritten signature recognition systems. Using graph norm for fast classification (filtration of potential users), followed by comparison of each signature graph concepts value against values stored in database, the system reports 94.25% identification accuracy.read more

Writer independent on-line handwriting recognition using an HMM approach
TL;DR: A combination of signal normalization preprocessing and the use of invariant features makes the HMM based writer independent handwriting recognition system robust with respect to variability among di!erent writers as well as di?erent writing environments and ink collection mechanisms.

TL;DR: Different sets of features are extracted from the recorded data and used to train a text and language independent on-line writer identification system based on Gaussian mixture models (GMMs) which provide a powerful yet simple means of representing the distribution of the features extracting from the handwritten text.
