Abstract

The invention discloses a counterfeit number recognition method and device and a computer readable storage medium, and relates to the field of data processing. The counterfeit number identification method comprises the following steps: detecting a longest user number public substring of a to-be-identified number and a user number field in a simulated number library and a matched user number fieldof a corresponding matched number; detecting the longest area code common substring of the area code fields of the to-be-identified number and the matched number; calculating the similarity between the to-be-identified number and the matched number according to the user number similarity between the longest user number public substring and the matched user number field and the area number similarity between the longest area number public substring and the area number field of the matched number; and determining whether the to-be-identified number is a counterfeit number according to the similarity and a preset counterfeit number threshold range. According to the invention, the recall rate of counterfeit number identification is improved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a counterfeit number identification method, device and computer-readable storage medium. Background technique [0002] In recent years, counterfeit number frauds that counterfeit public security laws, operators, banks, and courier numbers have accounted for a large proportion of telecommunications fraud. At the same time, the amount of fraud is huge and the social impact is bad. [0003] Counterfeit number fraud usually initiates a call abroad, by modifying the calling number so that the last few digits of the number are the same or similar to the domestic number to confuse the user, and then commit fraud. [0004] The counterfeiting algorithm adopted in the related art usually utilizes the left matching and right matching or exact matching of numbers, and the recall rate is low. Contents of the invention [0005] After analyzing related technologies, the inventor found that an ...
