Embodiment Construction
[0039] In the embodiment of this application, the security transaction identification information is determined for a single user; after receiving the transaction request sent by the user, multiple transaction features corresponding to the user's current transaction are extracted; according to the user-specific security transaction identification information, Determine the probability that the user conducts safe transactions and risky transactions under the multiple extracted transaction characteristics, and based on the determined probability that the user conducts safe transactions and risky transactions, conduct transaction control on the user's current transactions. It can be seen that the embodiment of the present application essentially provides a transaction control method that is completely different from the existing methods; The probability of safe transactions and risky transactions, so that the individual differences in transaction characteristics of different users...

The present application relates to the field of computer network technology, and in particular to a transaction control method and device, which are used to solve the problem of low accuracy of the existing transaction control method for each user based on the transaction data of all users. The transaction control method of the present application includes: after receiving the transaction request sent by the user, extracting multiple transaction features corresponding to the user's current transaction; The probability that the user's transaction is a safe transaction and the probability that the user's transaction is a risky transaction under the plurality of transaction characteristics; wherein, the safe transaction identification information includes that under each transaction characteristic, the user's transaction is a safe transaction according to the determined probability that the user's transaction is a safe transaction under the multiple transaction characteristics and the probability that the user's transaction is a risky transaction under the multiple transaction characteristics, conduct a transaction on the user's current transaction control.
Description
technical field [0001] The present application relates to the technical field of computer networks, in particular to a transaction control method and device. Background technique [0002] With the development of network technology, it is becoming more and more convenient and common for users to conduct transactions through the network. While network transactions bring convenience to users, they also bring certain risks. This requires the current needs of users Complete transactions for accurate transaction control. [0003] At present, in order to achieve transaction control, first extract all user transaction data, determine the overall difference characteristics of all safe transactions and risk transactions, and determine a safety transaction score for each difference characteristic; after receiving the user's transaction request, According to the overall difference characteristics of all security transactions and risk transactions determined and the security transaction...
