    Sammanfattning : It is desirable for companies to be able to hide data inside videos to be able to find the source of any unauthorised sharing of a video. The hidden data (the payload) should damage the original data (the cover) by an as small amount as possible while also making it hard to remove the payload without also severely damaging the cover.

    Sammanfattning : How amazing would it be to prevent illegal copies of computer games? Game developers work with the hope that they can make good profit out of their games, but when they know that they would not sell much they will be so disappointed and that is because once a few original copies of their games are released, soon or late, there will be illegal copies available in the market.
