    • PURPOSE: A device for inserting and detecting video watermarking by using a content adaptive type of time axis modulation and a method thereof are provided to generate a watermark pattern through analysis of a video histogram and change an average value of color difference of front and back frames corresponding to a watermark message, thereby strengthening geometrical transformation, filtering transformation, and compression format change of a watermarked video. CONSTITUTION: A histogram analysis unit(102) analyzes a histogram of a video image that compression is released through a compression decoding unit(100). A watermark pattern generation unit(104) generates a watermark pattern by using a histogram analysis result. A watermark message generation unit(110) generates a watermark message. A modulation unit(106) inserts the watermark message into a color difference component frame of a video by comparing large and small sizes of front and back frames of an original input video corresponding to the watermark pattern.

    • PURPOSE: A handover point determination device and a method thereof are provided to offer successive communication to a vehicle by determining the handover point using GPS(Global Positioning System) information and the strength of the signal transmitted from a base station. CONSTITUTION: When the number of effective base stations is two or more, a signal accumulation management unit(120) accumulates the strength differences of a signal transmitted repetitively from each effective base station. The signal accumulation management unit updates the handover accumulated determining value. A handover time point determination unit(140) executes the control operation in order to execute the handover of the vehicle satisfied with the set handover time value by considering the speed of the vehicle.

    • PURPOSE: A method for verifying key validity and a sever for performing the same are provided to reduce necessary operation times for verifying key validity in a signature process or a signature verification process by providing various services based on anonymous authentication. CONSTITUTION: An anonymous authentication server(110) revokes an anonymous secret key owned currently(S810). The anonymous authentication server is opened by generating a revocation list(S820). A service providing server(120) generates a LRL(Local Revocation List) by using a revocation list and its own LL secret key(S830). The service providing server calculates a virtual index of a service user through the signature of a service user(S840). The service providing server verifies the validity of a key of the service user based on the presence of the virtual index included in the local revocation list(S850).
