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.

Abstract: The technical solution of this disclosure is a children's toilet trainer, including a toilet seat ring that can hold a potty, the front end of the toilet seat ring is connected to first supporting legs on the left and right sides of the bottom surface, a first pedal is connected between the bottom of the left and right first supporting legs, the bottom of the first supporting legs is hinged to second supporting legs and limits the forward rotation of the second supporting legs, a second pedal is connected between the bottom of the left and right second supporting legs; when the second supporting legs are rotated backward in place relative to the first supporting legs, one end of the second pedal abuts against the bottom surface of the toilet seat ring for positioning.

Abstract: A method includes the following: a local identity verification request for controlling an in-vehicle device is sent to a first server, where the first server is configured to generate target verification information corresponding to the terminal device and the in-vehicle device for the identity verification request; the target verification information and a pre-constructed certificate chain that are sent by the first server are received, and the certificate chain and the target verification information are verified based on a predetermined key of the terminal device to obtain a verification result; and when the verification result is that the verification succeeds, a vehicle control instruction is processed based on the target verification information, and a processed vehicle control instruction is sent to the in-vehicle device, so that the in-vehicle device processes the vehicle control instruction based on the target verification information and the certificate chain.
