Abstract
A system for protecting copyright and content itself of digital contents generated with respect to their publication and distribution according to the means of wire/wireless communication, internet or off-line. First, digital contents inclusive of specific form of encrypted keys are received. A user compares such receipt with system information indicating characteristics of his/her unique system he/she is using, and when the compared information corresponds to each other, the digital contents are generated. The digital contents received in this regard are provided in a encrypted state according to the user's system information, and the digital contents are generated from extraction of decryption keys of the digital contents and from decryption of specific material among the digital contents. Accordingly, use only in the pertinent system is permitted so as to prevent illegal use of the contents.
