The invention relates to a method and
system for the
verification code service based on the cloud service. The method for the
verification code service based on the cloud service comprises the following steps that firstly, a
verification code request is sent to a could
server on a WEB
client, and the
control parameters of a verification code is attached to the verification code request; secondly, the
cloud server responds the verification code request and generates a verification code image, and the verification code image is returned to the WEB
client to be displayed; thirdly, a verification event is logged in a verification code input box of the WEB
client based on the verification code image; fourthly, after the verification code is input, the verification event is triggered, and an
AJAX request with the input verification code is sent to the
cloud server; fifthly, the
cloud server verifies the
AJAX request and returns a verification result to the WEB client to be displayed, and the verification code image is updated. The
system is established based on the method for the verification code service based on the cloud service. By the adoption of the method and
system for the verification code service based on the cloud service, the verification code cloud service can be provided for various websites, the problem that the websites are not identical in level is solved, and the safety of the verification code is improved.
