Μελέτη των μεταδεδομένων σε αρχεία του Microsoft Office X
Πάσχος, Χριστόδουλος Γ.
The present thesis studies the metadata in Microsoft Office X files. Initially, the meaning of metadata is defined and I present their usefulness in forensic analysis and privacy protection. Subsequently, I analyze the types of metadata in programs of the Microsoft Office X suite and the kind of information they reveal, while access instructions to them or screenshots of the programs themselves are provided. Microsoft's incorporated tool for the acquisition and removal of metadata is extensively discussed, providing examples and instructions. In addition, I mention some of the most popular commercial tools for viewing and clearing metadata and some open-source or freeware tools. Finally, I study the cases of metadata extraction from MS Word new and old file-type samples, using open-source tools and then I compare the results.
