<p>PURPOSE: A watermark image generation system and a method thereof for inserting location information into a basic water marking image are provided to allow a terminal to perform watermarking operations using a minimum of resources by inserting a watermarked image which includes location information. CONSTITUTION: A trace information generating unit(120) generates binary trace information based on a user ID or a user terminal ID. A location information managing unit(130) determines the range of the location information value and generates a location information value. The location information value distinguishes the location within the binary trace information for each bit value of the trace information. A watermark image generating unit(140) matches the location information value with the bit value of the trace information and generates the watermarked image by inserting the location information value into a basic watermarked image.</p> |
