Digital currency transaction abnormal user identification method and device based on abacus metaphor and medium

Abstract

The invention discloses an abacus metaphor-based digital currency transaction abnormal user identification method and device, and a medium. The method comprises the steps of obtaining all transaction records of a user of a digital currency exchange in a transaction time period; according to the transaction records, an abacus diagram is drawn and comprises a horizontal axis and a plurality of straight columns, the horizontal axis represents transaction time, and the straight columns vertically penetrate through the horizontal axis and are in one-to-one correspondence with the transaction records; the straight columns are arranged on the abacus beads above the transverse shaft, and the heights of the abacus beads are used for displaying transaction amount; the straight columns are arranged on the abacus beads below the transverse shaft, and colors and positions of the abacus beads are used for representing transaction currencies and types; counting the number of straight columns, the distance between the straight columns, the number of abacus bead colors and related statistical data in the abacus diagram; and judging whether each piece of statistical data exceeds a corresponding preset threshold value, and if the number of the statistical data exceeding the corresponding preset threshold value is greater than a preset value, judging that the user is an abnormal user. According to the invention, the transaction sequence data of the abnormal user can be visually and effectively displayed, and the abnormal user can be identified.

Description

technical field [0001] The present invention relates to the field of information visualization, in particular to a method, device and medium for identifying abnormal users of digital currency transactions based on the abacus metaphor. Background technique [0002] As of July 18, 2020, there are more than 5,740 types of digital currencies in the world, with a market value of 1.89 trillion yuan. The digital currency exchange is a platform for matching transactions between digital currencies, digital currencies and legal tenders (RMB, US dollars, euros, etc.), and is the main place for digital currency transaction circulation and price determination.

Problems solved by technology

Visualization methods such as scatter plots and line charts are often used to display price fluctuations and related information in the digital currency trading market, but it is difficult to effectively display the complex trading behavior of digital currency exchanges, and it is even more difficult to help regulators dig out users' information. Transaction patterns to judge and analyze abnormal users, therefore, a more reasonable and effective visualization method is needed
