摘要： A system for automatic detection of authenticity of security documents by measuring reflected components of incident energy in three or more optical wave bands. The system involves the use of UV-visible light source, an optional near infra red light source, photodetectors and associated sensing circuitry. Photoelectric signals generated by photodetectors from the reflected energy received from a security document are used to verify its authenticity under UV-visible along with optional near infra red illumination. The process involves measurement of energy reflected as photoelectric signals from a security document in at least three optical wavebands by suitably located photodetectors with appropriate wave band filters and the electronic signal processing to distinguish between a genuine document from a fake one for ultimate LED indicator display and audio-visual alarms, hence the detection of fake security document.

摘要： A currency genuineness detection system using plurality of opto-electronic sensors with both transmission and reflective (including fluorescence) properties of security documents is developed. Both detection sensing strategies utilise integrated response of the wide optical band sensed under UV visible along with optional near infra red light illumination. A security document is examined under static condition. A window signal signature is thus possible from photodetectors responses for various kinds of documents of different denominations, kinds and country of origin. A programmable technique for checking the genuineness of a security document is possible by feeding a unique code of the currency under examination.
