The iv images are images in which some messages are hidden, such as
the title, the names of people, location, time, copyright, explanation
or simply drawing etc.. The iv images use popular formats (currently
support PNG and TIFF formats). The iv images almost keep same size as
the normal images, that is, the messages do not take extra space.
However, the messages are shown at the exact position on the image.

Please visit www.iv-image.com
and feel free to download the software. Thanks

This technique is called "steganography". It can hide data in picture
or sound files by making minor changes to them, imperceptible to human
eyes/ears. Those interested should search on "steganography freeware"
or "digital watermarking".
