摘要： Provided is a method of preventing digital content stored in a universal serial bus (USB) mass storage (UMS) device from being distributed without restriction. In the method, registration data is encrypted in order to allow a UMS device to decrypt and use digital content using time information only within a predetermined term of validity. Accordingly, even if encrypted registration data of a UMS device is disclosed, it is possible to make it difficult for unauthorized devices to store the registration data, thereby preventing content of the UMS device from being distributed without restriction.

摘要： Provided are a method and apparatus for controlling transmission of content data. In the method, a communication channel is initially established to transmit the content data, the content data is transmitted through the established communication channel, verification is performed a plurality of times to determine whether the content data is transmitted within an acceptable transmission range, and whether to continue the transmission of the content data is determined according to the verification result. Accordingly, when a client moves to a location outside a predetermined acceptable transmission range in a wireless environment, a server stops transmission of the content data. In addition, content data can be continuously transmitted regardless of interference caused by a temporary obstacle between a server and a client.
