Abstract: Identification authentication methods and systems are provided. In accordance with some embodiments, a user can verify or authenticate an item to ensure if the item is authentic by utilizing a security token. For example, a user can authenticate a website to determine if the website is authentic by providing information to decrypt a security token, and the user can determine if the website is authentic by reviewing the decrypted security token. An authentication method between a user and a service provider can comprise generating a security token, presenting the security token to a user, decrypting the security token, and receiving user information to authenticate a user. The security token can based at least partially on user information, and can comprise encrypted token information. Decrypting the security token can occur dynamically in real time so the token information appears enabling a user to authenticate a service provider. Other embodiments are also claimed and described.
