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
An electronic device comprising:
- a sensor configured to obtain biological information of a user;
- a communication interface;
- a memory configured to store instructions;
- and
- a processor configured to execute the stored instructions to at least:
- selectively generate, in response to the user being authenticated based on the biological information, an encryption key to encrypt content of an external device,
- control the communication interface to transmit the encryption key to the external device,
- receive, from the external device, a notification indicating that an encrypted content is selected,
- in response to receiving the notification, determine a strength of a signal received from the external device,
- perform authentication of the user using the biological information based on the strength of the signal received from the external device,
- generate a decryption key for decrypting the encrypted content, based on performing the authentication of the user using the biological information, and
- control the communication interface to transmit the decryption key to the external device.
A method of generating an encryption key and a decryption key, the method being performed by an electronic device comprising a sensor and comprising:
- obtaining biological information of a user by using the sensor;
- authenticating the user of the electronic 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;
- receiving, from the external device, a notification indicating that an encrypted content is selected;
- in response to receiving the notification, determining a strength of a signal received from the external device;
- performing authentication of the user using the biological information based on the strength of the signal received from the external device;
- generating the decryption key for decrypting the encrypted content, based on authentication of the user using the biological information;
- and
- transmitting the decryption key to the external device.
A non-transitory computer-readable recording medium having recorded thereon a program for an electronic device comprising a sensor to execute a method of generating an encryption key and a decryption key, the method comprising:
- obtaining biological information of a user by using the sensor;
- authenticating the user of the electronic device based on the biological information;
- selectively generating, in response to the user being authenticated by the authenticating, the encryption key based on the biological information to encrypt content in an external device;
- transmitting the encryption key to the external device;
- receiving, from the external device, a notification indicating that an encrypted content is selected;
- in response to receiving the notification, determining a strength of a signal received from the external device;
- performing authentication of the user using the biological information based on the strength of the signal received from the external device;
- generating the decryption key for decrypting the encrypted content, based on authentication of the user using the biological information;
- and
- transmitting the decryption key to the external device.
