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.

Method and device for encrypting or decrypting content

An example electronic apparatus includes an information generator configured to generate information used to one function of a user terminal, a communicator configured to communicate with the user terminal, the server and a plurality of external apparatuses having a plurality of operation modes, and a controller configured to control the communicator: to attempt an access to the server at a first operation mode; in response to determining that the server is in a normal communication state based on the access attempt, to provide information generated by the information generator to the user terminal via the server; and in response to determining that the server is in a communication pending state based on the access attempt, to transmit a first mode changing signal for operating in a second operation mode, which restricts the access to the server, to at least one of the plurality of external apparatuses.

Electronic apparatus and control method thereof

A method of transmitting data via a data transmitting device in a wireless network environment is provided. The method includes determining whether traffic is saturated or not based on an access category (AC) into which the data is classified according to a type of application that transmits the data, a queue size, and a predetermined threshold value and determining a transmission scheme according to a determination result of whether traffic is saturated or not and the AC of the data.
