Data transmission based on verification codes

Abstract:

The present disclosure provides techniques for data transmission. According to one technique, a request from a data sender for sending data to a data receiver is received, wherein the request comprises a content indicating a verification code. Then, a first solution to the verification code based on the request can be obtained. The verification code can be sent to the data receiver. A second solution to the verification code can be received from the data receiver, wherein the second solution is generated by the data receiver. Transmission of the data from the data sender to the data receiver can be enabled in response to the first solution consistent with the second solution.
