Detailed Description
The technical scheme of the invention is specifically explained below with reference to the accompanying drawings.
As shown in fig. 1, the method for detecting abnormal transaction behavior of offline order-receiving service of the present invention includes:
s1, acquiring user transaction conditions in real time, wherein the user transaction conditions comprise user transaction identification codes (openid, trader IP, transaction amount, transaction address and the like) and merchant information (merchant unique identification codes, merchant geographic positions and the like);
s2, transaction validity verification:
a. the amount of money is abnormal: if the number of successful transactions with the absolute value of the difference between the multiple continuous transaction amounts within the preset range is greater than or equal to the preset percentage within the preset time of the same trader, the transaction with the abnormal amount can be determined;
b. transaction time period exception: in the non-operation period, the merchant determines that the transaction is abnormal time transaction if the transaction is in the non-operation period and the transaction is greater than the preset percentage;
c. transaction location exception: when the same merchant receives more than a preset number of remote IP address payments within the past preset time; namely, the transaction can be determined as an abnormal place transaction;
d. cash register transaction: when the number of merchants successfully transacting a single transaction in a preset time period is larger than a preset number, the merchant can be determined as a credit card transaction malicious cash register transaction; the cash-out transaction further comprises: if the payment to the same merchant is more than the preset number in the preset time of the same card, the cash register transaction is determined to exist; if the transaction amount of the non-large-amount transaction merchant type with the same card is larger than the preset amount, the cash register transaction can be determined to exist; or if the accumulated settlement of the same merchant is more than the preset amount within the preset time, the cash register transaction can be determined to exist;

s4, verifying the transaction behavior of the merchant, and observing the transaction if no abnormal transaction exists; and if the abnormal transaction exists, forbidding transaction initiation and informing the merchant.
The following is a specific example of the present invention.
The invention relates to a method for detecting transaction behavior abnormity of an offline order receiving service, which comprises the following steps:
1. acquiring the transaction condition of a user in real time; including user transaction identification (openid, trader IP, transaction amount), merchant information (merchant unique identification, merchant geographic location, etc.).
2. And judging whether the merchant is illegal according to the transaction behavior. The method is mainly calculated in the following aspects:
a. the amount of money is abnormal: and monitoring the transaction of the merchant for 24 hours according to the relevant parameters of the wind control model, and identifying the risk of the merchant and the transaction if abnormal transaction amount occurs, so that early warning and troubleshooting of wind control personnel are facilitated. The abnormal amount determination is described in detail as follows:
the trader can generate the unique identification code of the trader when trading, the absolute value of the difference between the amounts of a plurality of continuous trades is more than or equal to 0 and less than 70 percent of the number of successful trades with 10 yuan in the past 1 hour of the same trader; an anomalous amount transaction may be identified.
b. Transaction time period exception: and monitoring the transaction of the merchant for 24 hours according to the relevant parameters of the wind control model, and identifying the risk of the merchant and the transaction if abnormal transaction time occurs, so that early warning and troubleshooting of wind control personnel are facilitated. The detailed description is as follows:
for non-nighttime business type merchants, greater than 40% of transactions occur during non-business peak hours, such as 9 to 11 am, 19 pm to 5 am the following day. The illegal transaction condition of the merchant can be determined.
c. Transaction location exception: and monitoring the transaction of the merchant for 24 hours according to the relevant parameters of the wind control model, and identifying the risk of the merchant and the transaction if an abnormal transaction place occurs, so that early warning and troubleshooting of wind control personnel are facilitated.
