METHOD FOR META INFORMATION OF ORIGINAL WORKS AUTOMATIC REGISTRATION THROUGH DERIVATIVE WORKS, AND THE DEVICE THEREOF

摘要

The present invention relates to a method for automatically registering meta-information of first works through second works, comprising the steps of: obtaining the first works and the N^th meta-information of the first works (N is a natural number more than or equal to three); generating N^th second works and the meta-information of the N^th second works based on the obtained first works; modifying the N^th meta-information of the first works based on the meta-information of the generated N^th second works; and registering the N^th meta-information of the modified first works. The present invention generates (N+1)^th second works after generating the N^th second works. Modifying the meta-information adds the meta-information of the N^th second works to the N^th meta-information of the first works and accumulates/modifies the meta-information of prior second works.
