Abstract
A wearable device includes a user information obtainer configured to obtain user information, a controller configured to selectively generate, in response to a user being authenticated based on the user information, an encryption key for encryption of content of an external device; and a communicator configured to transmit the encryption key to the external device.
Claims18
A wearable device comprising:
- a user information obtainer comprising a hardware sensor configured to obtain biological information of a user;
- a controller configured to selectively generate, in response to the user being authenticated based on the biological information, an encryption key to encrypt content of an external device;
- and
- a communicator configured to transmit the encryption key to the external device,
- wherein the controller is further configured to determine, using the biological information, whether the user is currently wearing the wearable device and generate, in response to determining that the user is currently wearing the wearable device, a decryption key to decrypt encrypted content.
A method of generating an encryption key and a decryption key, the method being performed by a wearable device comprising a hardware sensor and comprising:
- obtaining biological information of a user by using the hardware sensor;
- authenticating the user of the wearable device based on the biological information;
- selectively generating, in response to the user being authenticated by the authenticating, the encryption key to encrypt content in an external device;
- transmitting the encryption key to the external device;
- determining, using the biological information, whether the user is currently wearing the wearable device;
- and
- generating, in response to determining that the user is currently wearing the wearable device, the decryption key to decrypt encrypted content.
