Embodiment 1

[0045] A barcode encryption and decoding module 1 of a detachable mobile device, such as figure 1As shown, it contains the following components:

[0046] The hardware interface 11 is for physically connecting with the mobile device. Mainly a wired connection, but also a wireless connection, using bluetooth or wifi.

[0047] The communication component 12 communicates with the mobile device. After receiving the authorization information (that is, the asymmetrically encrypted ciphertext) sent by the mobile device, it is transmitted to the decoding and encryption component through the decoding control chip.

[0048] The decoding and encryption component 13 includes the root public key and the asymmetric encryption public and private key pair of the device, uses the root public key to decrypt the authorization information, and feeds back the decrypted result to the decoding control chip 14 for comparison, and the decoding control chip 14 compares Whether the decrypted result ma...

Abstract

According to the barcode encryption and decoding application method of an external mobile device according to the present invention, the mobile device establishes a physical connection with the mobile device, so that the barcode encryption and decoding module can be used as an external device of the mobile device. When the mobile device detects that the barcode encryption and decoding module is connected, the control key authentication module sends authorization information to the barcode encryption and decoding module. After receiving the decryption authorization information successfully, the device asymmetrically encrypts the public and private key pair with the mobile device. Negotiate to generate a symmetric encryption key, and send the barcode image pre-decoding information to the barcode encryption and decoding module after the negotiation is successful. Only after the decoding control chip confirms that the double verification is successful, the mobile device is allowed to use the barcode decoding function, so that the decoding control chip will not be copied. And the barcode image pre-decoding is carried out by the mobile device, and the image processing capability of the mobile device is used for preliminary image processing, which reduces the image processing pressure of the barcode encryption and decoding module and improves the barcode decoding speed.

Description

technical field [0001] The invention relates to a barcode decoding hardware encryption module, in particular to a barcode encryption and decoding module and system of a detachable mobile device. Background technique [0002] At present, the industrial-grade PDA barcode reading equipment on the market is all special equipment, such as our company's MT65, MT80, etc., all of which have specially designed barcode image acquisition equipment. Using models such as barcode reading modules EM2028, EM3000, etc., combined with dedicated hardware decoding chips or dedicated software decoding libraries, the barcode reading equipment has the advantages of fast reading speed and high reading success. With the rapid popularization of software such as WeChat and Alipay, ordinary mobile phones have a certain ability to scan and read barcodes. However, since no dedicated hardware decoding chip is used for decoding, and software decoding is also based on an open decoding library, there is a l...
