The present invention relates to an apparatus and method that control a vessel deviating from an anchorage using wide-range sensor-based spherical trigonometry. In the method, vessels anchored in an anchorage are monitored. The anchorage is defined as a group, and the group of the anchored vessels is managed. Leaving of a vessel, needing to deviate from the anchorage, from the group is controlled. If a vessel recognized as a vessel identical to one that left the group requests anchoring after a predetermined period of time has elapsed, the anchoring-requesting vessel is controlled.

The present invention relates to an agent apparatus and method for sharing anonymous identifier-based security information among security management domains. A plurality of security information sharing agent apparatuses respectively located in a plurality of security management domains and configured to collect security information and transmit collected security information to outside of the security management domains. Each security information sharing agent apparatus includes an identifier conversion unit for converting real name identifier-based security information into anonymous identifier-based security information by converting a real name identifier included in the security information into an anonymous identifier, and a security information communication unit for transmitting the anonymous identifier-based security information obtained by the identifier conversion unit to outside of a corresponding security management domain so that security information is shared among the plurality of security management domains.

An authentication apparatus for a non-real-time IPTV system decrypts a first encrypted value included in a contents request message received from a device using a preset session key, and then verifies the validity of the contents request message. If the verification results of the contents request message are valid, the authentication apparatus encrypts a variation between timestamps of the authentication apparatus and the device using the session key, and then generates a second encrypted value. After verification information by which the device is capable of verifying the authentication apparatus has been generated using the second encrypted value, the authentication apparatus sends verification information, together with contents corresponding to the contents request message, to the device.

A security label generation apparatus for scalable content distribution, includes a scalable content transmitter for receiving service level requirements of a user and network bandwidth information over a network and generating security labels and encrypted scalable units. Further, the security label generation apparatus includes a scalable content receiver for receiving the encrypted scalable units and the security labels from the scalable content transmitter and for decrypting, decoding, playing, modifying, storing or redistributing the encrypted scalable units based on the security labels. Furthermore, the security label generation apparatus includes scalable content storage for searching for scalable content and metadata corresponding to a request of the scalable content transmitter.
