1. A personal identification system based on the reading of multiple one-dimensional barcodes scanned from PDA/cell phone screen, comprises a multiple one-dimensional barcode generating system and a reading system of multiple one-dimensional barcode on PDA/cell phone screen, wherein said multiple one-dimensional barcode generating system is consisted of a data input unit and a barcode generating unit, wherein said data input unit can be used to input the original data of said barcode and then said original data are transmitted to said barcode generating unit where a corresponding barcode is created;

  • the reading system of multiple one-dimensional barcode on PDA/cell phone screen is based centrally on image processing/identification technology and is consisted of a PDA/cell phone reaction unit, a CCD camera, a frame grabber, an image processing unit, a barcode recognition unit and a data recording unit, wherein said PDA/cell phone reaction unit is responsible for detecting the PDA/cell phone entered into the detection area, and sending the detected signal to the frame grabber in order to trigger the CCD camera for taking the image on the PDA/cell phone screen;

    said multiple one-dimensional barcode image taken by said CCD camera from said PDA/cell phone screen is processed by said image processing unit into a binary image which is recognized completely by said barcode recognition unit decodes and the result recognized is backup in said data recording unit.
