a second step of generating the first identification information, the device identification information and the verification request information to the target blockchain system 300, where the target blockchain system 300 is configured to perform an authorization verification process on the fee collection platform 100 based on the device identification information (e.g., verify whether the fee collection platform 100 is registered in the target blockchain system 300 based on the device identification information, i.e., whether there is authorization to acquire two-dimensional code identification information), and perform an integrity and consistency verification process on the target two-dimensional code identification information corresponding to the first identification information on the target blockchain based on the verification request after the authorization verification process is passed (e.g., verify whether the target two-dimensional code identification information is tampered, for example, the target two-dimensional code identification information on all blocks is not the same or only a part of the blocks have target two-dimensional code identification information stored therein, may be deemed tampered with) and sends the target two-dimensional code identification information to the fee collection platform 100 after the integrity and compliance verification process has passed.
In summary, according to the fee collection method and the fee collection platform 100 based on the block chain provided by the present application, after the target payment device 200 generates the target two-dimensional code image, the corresponding target two-dimensional code identification information is generated and sent to the target block chain system 300 for storage, so that the fee collection platform 100 can obtain the target two-dimensional code identification information through the target block chain, and thus, the target two-dimensional code image is identified. Therefore, the security of the identification processing of the target two-dimensional code image can be improved, and the problem of low security in the existing fee collection technology is solved.
