Abstract

Embodiments of the invention provide a number detection method and device. The number detection method is applied to a server, and comprises the steps: obtaining query data sent by a client, the querydata being data of a previous preset number of bits after a target number is processed by an MD5 algorithm; determining to-be-determined number data matched with the query data in a preset rainbow table covering the whole network number; determining feature information of the to-be-determined number corresponding to the to-be-determined data according to the to-be-determined number data in combination with a feature database of the whole network number; and sending the feature information of the to-be-determined number to the client. Therefore, a plaintext is not adopted when the number is detected, the privacy of the user is protected, and the security is improved.

Description

technical field

[0001] The present application relates to the technical field of electronic commerce, in particular to a number detection method and device. Background technique

[0002] With the rapid development of electronic technology, electronic devices are becoming more and more popular, and the functions of electronic devices such as APP (application program) are also becoming more and more abundant. Some speculators use a large number of mobile phone numbers to engage in garbage registration, fleece and other illegal activities that seriously damage businesses. Behavior. In the prior art, the technical scheme of black and gray product identification based on the plaintext of the mobile phone number can determine the black and gray product through the mobile phone number, but it will involve the issue of privacy leakage and pose a security risk. Contents of the invention

[0003] In view of the above problems, the embodiment of the present application provides a nu...
