Abstract

A method and apparatus for protecting shared data and method and apparatus for reproducing data from a recording medium using a local storage are disclosed. The present invention includes downloading the shared data associated with a recording medium to a local storage and permitting an application having valid access information for the shared data to access the shared data. The present invention includes downloading encrypted shared data associated with the recording medium to the local storage, constructing a virtual package including the shared data by binding data within the local storage to data within the recording medium, decrypting the shared data using the virtual package, and reproducing the decrypted shared data. Accordingly, the contents provided by an authentic content provider and the non-transmuted contents can be reproduced, whereby the shared data can be protected. And, the shared data can be protected against a malicious function caused by an unauthorized application.
