Abstract: Information processing performed by an information code server end includes receiving an information code processing request from a second client, where the information code processing request is sent after the second client scans a third-party information code embedded in a first client. To obtain identified risk information, risk identification is performed based on the information code processing request. Based on the identified risk information and a predetermined security rule, corresponding processing logic is executed. A processing result of the corresponding processing logic is sent to the first client.
