Patent abstract
Systems and methods for generating a dynamic verification value for electronic payment transactions are disclosed. A user of a portable consumer device enrolls the account identifier associated with the portable consumer device and specifies one or more customized linkage rules that identify one or more user communication devices and user identifiers that should be used to submit an authentication request message to an entity that generates a dynamic verification value. A server computer that receives an authentication request message determines whether the authentication request message complies with the specified customized linkage rules and generates a dynamic verification value.
