AUTHENTICATION IN UBIQUITOUS ENVIRONMENT

摘要

In some embodiments, encrypted biometric data are stored in advance in a device that is possessed or carried by a user based on a public key certificate, and a user authentication (S703) is performed by a biometric matching in the device. A public key certificate matching the encrypted biometric data is used to perform a user authentication (S704,S705,S706,S707) for a transaction authorization in a service providing server. According to some embodiments, one time password, keystroke, dynamic signature, location information, and the like are employed as additional authentication factors to tighten the security of the first and second user authentications. According to some embodiments, an authentication mechanism including the first user authentication and the second user authentication is applied to control an access to the IoT device.
