摘要： PURPOSE: A method and a device for inserting a fingerprint into digital contents to trace an illegal user are provided to correctly detect information without generating interference between user information even if a collusion attack such as an average attack or a mosaic attack is received. CONSTITUTION: A seed value selector(210) selects a seed value for generating a pseudo random number. A pseudo random number generator(220) generates the pseudo random number corresponding to transaction information based on the selected seed value. A fingerprint inserter(250) inserts the generated pseudo random number into the digital contents(240).
