Abstract
Generating verification codes includes selecting at least two verification code generators from a verification code generator set comprising a plurality of verification code generators to compose a current use set, executing each verification code generator in the current use set to obtain corresponding partial verification codes, composing a current verification code from the partial verification codes, outputting the current verification code to a user, receiving a user response that is made in response to the current verification code, and comparing the current verification code and the user response to determine whether the user is verified.
