Abstract
A verification code generation method is performed at a computing device. The method includes: obtaining at least one pattern; determining an association relationship between the patterns and object attributes of the one or more objects in the patterns; generating at least one verification question according to the association relationship, and correspondingly marking an answer pattern matching each verification question from the at least one pattern; and generating at least one verification code picture according to the at least one pattern, the object attributes in the patterns, and the generated verification question, patterns in the verification code picture satisfying the association relationship, the verification code picture corresponding to the at least one verification question, the verification code picture including an answer area matching the corresponding verification question, and the answer area being an effective operation area that is determined according to an answer pattern of the corresponding verification question.
