Abstract: Systems and methods for utilizing one or more cameras at a mobile device to assist in the implementing anti-counterfeit measures for digital barcodes are disclosed. For example, the systems and methods use a mobile device's front camera to capture photographs (or images) at a certain frequency (e.g., capture a photograph every 0.20 seconds). The systems and methods then scan the captured photograph and retrieve relevant image data (for example, scan image vertically and utilize image data of every fourth pixel). The systems and methods compare certain properties of the retrieved image data with properties of one or more comparison light sources. When the systems and methods detect a match (for example, a match within certain threshold parameters), they identify a barcode among a set of barcodes and display the identified barcode at a display screen of the mobile device.
