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.

Abstract: A method for account parallel processing used by an account processing center to process a request for account operation is disclosed. The method comprises: (1) categorizing accounts as high parallel occurrence accounts and common accounts; (2) when receiving the request from the client for processing operation of an account, firstly determining whether the account is a high parallel occurrence account; and if the account is a high parallel occurrence account, continuing to a step (3), otherwise, conducting a step (4); (3) if the account is locked, queuing a current operation to wait until implementation of the current operation; and (4) further determining, by the account processing center, whether the account is locked and outputting an error message when the account is locked, otherwise implementing the current operation. Such method provides more high quality services to the high parallel occurrence accounts.
