1. A verification data processing method, comprising: receiving, by a server, CAPTCHA response information that is sent by a user through a user terminal; obtaining an IP address of the user terminal from the CAPTCHA response information; obtaining verification data by verifying the CAPTCHA response information; storing the verification data in a preset hash table, wherein the verification data comprises a type of a CAPTCHA code corresponding to the CAPTCHA response information, and a number of total verifications of CAPTCHA response information and a number of correct verifications among the total verifications which both correspond to the IP address of the user terminal; determining a user type of the user according to the IP address of the user terminal, the number of total verifications and the number of correct verifications; storing the verification data in a min-heap according to the type of the CAPTCHA code and the user type of the user; and making a statistic of all the numbers of total verifications and all the numbers of correct verifications in the min-heap to obtain a passing rate of CAPTCHA codes which correspond to the CAPTCHA response information from which all the verification data in the min-heap is obtained.
