Abstract (en)

[origin: WO2006065050A1] The present invention relates to a method for securing content on a recording medium. Input content data are encrypted and recorded on a recording medium. A resultant value obtained by applying a hash function to the content data recorded after encryption is recorded on the recording medium for validation of the content. According to the present invention, once hashing operation for validation of content is carried out after encryption of content data is done, an apparatus for reproducing a recording medium storing content can easily check the validity of stored content by carrying out hashing operation only.
