Abstract
Disclosed are an apparatus and method for setting rights for each object of a piece of content. A data detection unit detects, for each object, data regions corresponding to each of a plurality of objects in the source code of a piece of digital content including the plurality of objects. A data encryption unit encrypts the data region from among the plurality of data regions that corresponds to the object subject to protection. A data transmission unit transmits the source code of the piece of digital content including the encrypted data region to a user terminal. According to the present invention, use rights can be authorized for each object included in a piece of content, and therefore a user may be provided with the selected object according to the right of the user for the same content. Further, a file may be executed even on a computer in which a DRM program is not installed, and it is possible to set the file such that a user may not access only the encrypted object in the file being executed.
