Embodiment Construction

[0039] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a number detection method of the present application, which is applied to a server, and may specifically include the following steps:

[0041] Step 101, acquire the query data sent by the client.

[0042] Wherein, the query data is the data of the pre-preset digits after the target number to be detected is processed by the MD5 algorithm.

[0043] In the specific implementation, the user wants to check whether a mobile phone number is a black number. For example, the target number to be detected is: 12345678912. First, the target number is encrypted according to the MD5 algorithm, and then the preset digits are intercept...

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...
