Machine Assisted Authentication of Paper Currency: an Experiment on Indian Banknotes

摘要

Automatic authentication of paper money has been targeted. Indian bank notesare taken as reference to show how a system can be developed for discriminatingfake notes from genuine ones. Image processing and pattern recognitiontechniques are used to design the overall approach. The ability of the embeddedsecurity aspects is thoroughly analysed for detecting fake currencies. Realforensic samples are involved in the experiment that shows a high precisionmachine can be developed for authentication of paper money. The systemperformance is reported in terms of both accuracy and processing speed.Comparison with human subjects namely forensic experts and bank staffs clearlyshows its applicability for mass checking of currency notes in the real world.The analysis of security features to protect counterfeiting highlights somefacts that should be taken care of in future designing of currency notes.
