Increasing the information capacity of digital images in telecommunication systems
Nowadays a lot of digital images are used in different areas of life. For example, almost every mobile device has an embedded photo camera that is mostly used just to make photos. It’s well known that digital images have some special properties ordinary used in compression algorithms. All compression systems use statistical and psychophysitial redundancy of digital images. In many cases (medicine databases with X-ray photos, private photo alboms, etc.) we need additional information about choosen images. It’s possible to solve this task by adding some additional information to initial images and using it by request. This information should be added while creating the image. This information may contain date, place, name of the person , etc. This information shouldn’t cause visible distortions to the image and shouldn’t be accessible for unauthorized user. Some of this information may be obtained automatically by mobile device (place - by GPS; time-by onboard clock, etc.), and some could be added by user.
