Title: DIGITAL DATA EDIT CONTROL METHOD, DEVICE, AND PROGRAM, AND COMPUTER READABLE STORAGE MEDIUM
Abstract:
[Problem] To clearly indicate in a non-modifiable manner if editing is permitted in each part of a piece of content when published by an author. [Solution] A piece of content is divided into six parts (A1-A6) for example (d). Null data is arranged such that each piece of partial content can have partial content added thereto (d). If a piece of partial content (A1) can be modified, an individual signature is stored in a table (Gc)(l), and if that piece of partial content (A1) can be deleted, a different individual signature is stored in a table (Gd)(m). If further partial content can be added to that piece of partial content (A1), another different individual signature is stored in a table (Ga)(n). No individual signatures in these tables means that modification and deletion of and addition to the corresponding piece of partial content are not permitted.
