The Method of Automatic Knuckle Image Acquisition for Continuous Verification Systems
Get PDFThe paper proposes a method of automatic knuckle image acquisition for continuous
verification systems. The developed acquisition method is dedicated for verification systems in
which the person being verified uses a computer keyboard. This manner of acquisition enables
registration of the knuckle image without interrupting the user’s work for the time of acquisition.
This is an important advantage, unprecedented in the currently known methods. The process of
the automatic location of the finger knuckle can be considered as a pattern recognition approach
and is based on the analysis of symmetry and similarity between the reference knuckle patterns
and live camera image. The effectiveness of the aforesaid approach has been tested experimentally.
The test results confirmed its high effectiveness. The effectiveness of the proposed method was also
determined in a case where it is a part of a multi-biometric method
