Abstract:
A wireless charging system and a method of controlling permission for charging in the wireless charging system are provided herein. The wireless charging system includes a power transmitting unit and an authentication server. The power transmitting unit transmits a power receiving unit (PRU) control message to a power receiving unit, receives PRU dynamic parameter characteristics generated by the power receiving unit based on an authentication number input by the user of the power receiving unit, and wirelessly supplies charging power to the power receiving unit based on the input result of authentication. The authentication server authenticates the authentication number input by the user and included in the PRU dynamic parameter characteristics provided by the power transmitting unit, and transmits the result of the authentication to the power transmitting unit.

The processing unit generates the notification data, including the knowledge information, using food information, indicated by the food identifier, and the personal information.
Abstract:
A method of collecting peer-to-peer (P2P)-based content sending/reception information is disclosed herein. In the method of collecting P2P-based content sending/reception information, a first peer accesses a second peer, and exchanges buffer maps with the second peer. The first peer requests the second peer to send a piece of content not owned by the first peer. When the reception of the piece of the content is completed, the first peer generates a receipt message and then signs the receipt message. The first peer sends the signed receipt message to the second peer. The second peer signs the signed receipt message again. The second peer sends the dually signed receipt message to a server.
Abstract:
An apparatus and method for controlling access to websites using a history of access of an administrator are disclosed. The apparatus includes a privilege checking unit, an access control release unit, and an access control unit. The privilege checking unit determines whether the access privileges of a user are administrator privileges when the user attempts to access a website. The access control release unit sets the website to an access-allowed state if the access privileges of the user are administrator privileges. The access control unit controls access to the website if the access privileges of the user are not administrator privileges, nor is the website in an access-allowed state.
