Abstract:
1. An active barcode authentication system that enables a store end to identify the ID of a user, wherein the store end has a store end key and a store end code, the system comprising: a barcode scanning device that reads plural barcodes; a portable device with a screen, the portable device having at least one barcode coding module, the barcode coding module coding a user ID code and a user encrypted message to at least one set of encrypted message barcodes and presenting the set of encrypted message barcodes on the screen of the portable device, the screen of the portable device facing to the barcode scanning device in order to let the image of the set of encrypted message barcodes on the screen be captured by the barcode scanning device; an identification host that connects with the barcode scanning device for identifying the image captured by the barcode scanning device and then gaining the user ID code and the user encrypted message, the identification host having at least one encryption module and an SSL (secure socket layer) module, wherein the encryption module encrypts the user ID code, the user encrypted message and trade information provided by the store end to a store end encrypted message via the store end key; and an authentication host that connects with the identification host, the identification host transmitting the store end code and the store end encrypted message to the authentication host through the SSL module, the authentication host having a decoding module and a verifying module, wherein the decoding module decodes the store end encrypted message and the user encrypted message for gaining the initial information before encryption of the user and the verifying module is to verify whether the user conforms to the conditions of trade and authentication or not.
