Abstract: The present disclosure is drawn to systems and methods for implementing authentication protocols based on trusted execution environments. Each of a principal device, an identity provider server and a service provider server are associated with a respective trusted execution environment. Authentication protocols are provided for registering the principal device to the identity provider server; authenticating the principal device to the identity provider server; and authenticating the principal device to a service provider server.

Abstract: A wearable device-based information transfer method and a related device where the method includes recording, by a first wearable device, a first event parameter corresponding to a social action when detecting that a first user wearing the first wearable device performs the social action, obtaining, by the first wearable device, a second event parameter released by a second wearable device, and determining, by the first wearable device, whether the first event parameter matches the second event parameter, and sending, by the first wearable device, first user-defined information to the second wearable device when the first event parameter matches the second event parameter. Hence, information transfer efficiency may be effectively improved.
