TH97471B - "Device for detecting credit card fraud" - Google Patents

Abstract

Method of analysis and system structure For inspection of the quality and counterfeit of a hologram on banknote products, identification or credit cards Detects tampering with the holographic image on credit cards. According to this invention contains At least two broadand light sources For producing colored light White to be projected onto a hologram that needs to be inspected with different incidence angles, digital cameras or light detectors. For the light reflected from the desired hologram. Such checks for electrical signals (lpixel) and control and processing units. A video signal that is composed of a neuron network for processing. Electrical signal received from the camera And control at least two light sources As mentioned, work one source at a time. With unique characteristics Control and processing unit The video signal analyzes each electrical signal received by the camera as The three primary colors signals red, green and blue are then fed to the converted signal as input to the Such neural networks To determine whether the hologram is genuine or fake.
