Fig. 1 is a flowchart of a risk control method for a virtual currency legal tender transaction according to an embodiment of the present invention, as shown in fig. 1, the method includes the steps of:

step S102, a target merchant is crawled out from a target platform, wherein the target platform comprises: the system comprises a virtual currency transaction platform and a legal currency transaction place, wherein the target merchant is a merchant selling virtual currency;

in particular, a crawler may be utilized to crawl from a virtual currency transaction platform and legal exchange to merchants selling virtual currency.

Step S104, generating a virtual purchase order for the target merchant;

in particular, the purchase is automated using a crawler, without payment, to generate a virtual purchase order for each target merchant.

Step S106, based on the virtual purchase order, obtaining the public information of the target merchant;

specifically, after the virtual purchase order of each target merchant is obtained, the crawler program is used for crawling out the public information of the target merchant contained in each virtual order.

It should be noted that the public information includes at least one of the following: the payment account number of the target merchant, the WeChat account number of the target merchant, the bank card account number of the target merchant and the mobile phone number of the target merchant.

And S108, constructing a virtual currency account risk library by utilizing the public information of the target merchant, and carrying out risk control on the virtual currency legal currency transaction by utilizing the currency account risk library.

In an embodiment of the present invention, a target merchant is crawled from a target platform, wherein the target platform comprises: the virtual currency transaction platform and the legal currency transaction place are used for enabling a target merchant to be a merchant selling virtual currency; generating a virtual purchase order for the target merchant; acquiring the public information of a target merchant based on the virtual purchase order; the method comprises the steps of establishing a virtual currency account risk library by utilizing the public information of a target merchant, and performing risk control on the virtual currency legal currency transaction by utilizing the currency account risk library, so that the purpose of performing risk control on the virtual currency legal currency transaction by utilizing the currency account risk library is achieved, the technical problem that the transaction risk exists in the virtual currency legal currency transaction in the prior art is solved, and the technical effect of reducing the transaction risk of the virtual currency legal currency transaction is achieved.

In the embodiment of the present invention, step S108 includes the following steps:

step S11, encrypting the public information of the target merchant by using a preset encryption algorithm to obtain encrypted public information;

and step S12, constructing a virtual currency account risk library by using the encrypted public information.

In the embodiment of the present invention, after the public information of the target merchant is obtained, the public information may be encrypted by using an MD5 encryption algorithm to obtain the encrypted public information.

And then storing the encrypted public information into a Mysql database, thereby obtaining a pseudo-currency account risk database.
