Embodiment Construction

[0045] see figure 1 As shown, a method for binding a two-dimensional code decoding library and a supporting camera of the present invention, the method specifically includes the following steps:

[0046] Step 1, the camera is connected to a CPU through a Camera interface and an I2C interface, the Camera interface is used to transmit image data, and the I2C interface is used to transmit camera configuration control commands;

[0047] Step 2, the CPU transmits the camera configuration control command through the I2C interface to configure the camera and start the camera, and the CPU receives the image data through the Camera interface;

[0048] Step 3, judge whether the camera is compatible with the two-dimensional decoding library; if not, end the process; if yes, encrypt and sign the image data, and enter step 4;

[0049]Step 4. Verify the image data of the encrypted signature; if the verification is successful, decode the image data and enter step 5; otherwise, return to ste...

Abstract

The invention provides a method for binding a two-dimensional code decoder library with a matching camera. The method comprises the steps that 1, the camera is connected with a CPU through a Camera interface and an I2C interface; 2, the CPU transmits a camera configuration control command through the I2C interface and receives image data through the Camera interface; 3, whether the camera is matched with the two-dimensional code decoder library is judged, if not, the process is ended, and if yes, the image data are encrypted and signed and the step 4 is executed; 4, the signature of the image data is verified, if the verification succeeds, the image data are decoded and the step 5 is executed, and if the verification fails, the step 2 is executed again; 5, a decoding result is acquired and fed back to a client application program, next image data are acquired, and the operation is cyclically carried out till all image data are decoded. The invention further provides a system for binding the two-dimensional code decoder library with the matching camera. The binding mode is low in cost, and security is improved.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular to a method and system for binding a two-dimensional code decoding library and a matching camera. Background technique [0002] In modern commercial activities, QR codes are widely used, such as product anti-counterfeiting / traceability, advertising push, commodity trading, information transmission and so on. With the vigorous development of the domestic Internet of Things industry, more two-dimensional code technology application solutions have been developed. [0003] The current methods of providing two-dimensional code solutions mainly include: [0004] A) A separate decoding library is provided, but no supporting dedicated camera is provided. The decoding effect and speed of this method cannot be guaranteed, and cannot meet special industrial applications. Moreover, customers do not need to purchase another authorization after purchasing an authorization, and can us...
