The method includes that a service side receives a username and a first value from a client side, searches a seed of a dynamic password token, and generates a first dynamic password according to the first value and the seed, converts the first dynamic password to the first authentication password and the second authentication password, and sends the first authentication password to the user; the dynamic password token generates a second dynamic password and sends the first authentication password to a user; the dynamic password token generates a second dynamic password and converts the second dynamic password to a third authentication password and a fourth authentication password; the user compares the first authentication password and the third authentication password to determine that they are identical, so as to confirm that the user is legal or the transaction is permissible. The invention prevents malicious attack and operation of illegal users, which improves the security of information and property of the users."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Authentication method, system, and device","description":"The present invention provides an authentication method, an authentication system, and an authentication device, which is in information security field.
