The safety of communication in organizations is a very important issue. It is about confidentiality, integrity and authentication during access or editing of confidential internal documents. A non-conventional means to increase security is the use of steganography to hide documents in digital videos, which makes possible to hide higher amounts of information and documents than steganography in images. In this work, we present a steganography technique using MPEG-4 videos aiming to increase documents secrecy. We also propose an architecture for version control of collaborative documents using encryption techniques, together with steganography, providing authentication and electronic documents integrity.
