On-Line Signature Verification Using Global Features, Akrum Mamdouh Shawky

Archived Theses and Dissertations

The work presented in this thesis deals with the development of an on-line Handwritten Signature Verification methodology based on certain Global features that represent the entire signature as a whole. The aim of the research is to come up with an efficient "acceptance/rejection" mechanism that can be used to verify the authenticity of a certain signature. Global features are less expensive to compute than local features, they provide fast verification, and should provide accurate verification results. After identifying the entire global set of attributes that are to be investigated, Cramer's v-statistics and information-theoretic entropy measures of association were used in …
