Description
Technical Field
The invention relates to the technical field of internet blockchains, in particular to an image-based blockchain wallet address generation method, a payment device and electronic equipment.
Background
In the prior art, the image copyright refers to the exclusive right that an author has on the image works (including photographic pictures, films and the like) created by the author, and the owner of the image can make profit through the image works.
The existing profit path of image works is realized by an image wallet technology: generating a two-dimensional code for a payee account, attaching the two-dimensional code to an original image to be charged, scanning the two-dimensional code of the payee account through an APP and sending the two-dimensional code to a payment platform when a user pays for a payee of the original image, and analyzing the payee account from the two-dimensional code and analyzing a payment account by the payment platform; and when the user inputs and submits the amount, the payment platform finishes deduction. This is a wireless payment scheme based on account hierarchy. Under the payment scheme, the owner of the original image can compile transaction information such as account number, commodity price and the like into a two-dimensional code, and print the two-dimensional code on various carriers such as newspapers, magazines, advertisements, books and the like to be issued together with the original image. And the user can realize payment with the account of the merchant by scanning and shooting the two-dimensional code through the mobile phone client.
In the process of implementing the invention, the inventor finds that at least the following problems exist in the mode in the prior art:
in the prior art, a user scans a code through a mobile phone and jumps to a specified payment interface so as to finish payment. The two-dimensional code is easily modified or destroyed by others, and if the original two-dimensional code is covered by the two-dimensional code generated by the other people collection address, a user can easily obtain an incorrect payment address, so that property loss is caused. Meanwhile, because a plurality of two-dimension code scanning tools do not have the capability of identifying and intercepting malicious websites, a great spreading space is provided for mobile phone viruses, and the two-dimension code scanning channel is prevented from being infected by the scanning and detection of online malicious websites and payment environments.
The prior art payer way can not realize the direct transaction of the payer to the payee, and the transaction can be finished only by the payment (such as a Paibao, a WeChat and the like) of a third party platform, is centralized and has certain transaction cost. There is also a risk that the online transaction will be compromised.
