    • A system for providing digital contents by using digital fingerprinting includes a contents generation server (140) for generating the digital contents; a clearing house (130) for issuing license of the contents to the client (100) and generating fingerprint information from informatin related to contents purchase information; a fingerprint management server (120) for generating fingerprint code based on the fingerprint information; and a contents distribution server (110) for delivering the contents to the client after inserting the fingerprint code into the contents in watermark form. By generating fingerprint code from information such as copyright holder of the contents, contents provider, etc. and insering the fingerprint code into the contents in watermark form, an illegal distributor can be traced with the fingerprint watermark, although digital contents provided to the client may be illegally copied and re-distributed. Digital content is not encrypted in order for purchaser to replay it on other media devices.
