Icemark Overview

Icemark is a state-of-the-art system for protecting digital images against illegal use. It allows you to embed an invisible watermark with information about the owner into an image.  It can be some text or an image identifier. This watermark is embedded into an image with the help of a private key so that only that owner can detect and read it.

Main features

• Custom watermark intensity – the watermark is embedded with varied intensity so that the user can choose between how unsusceptible and how perceptibility the watermark is.
• Unlimited number of watermarks – the license allows you to add an unlimited number of watermarks.
• Highly unsusceptible to image changes – the watermark is unsusceptible to JPG compression, geometric distortions, cropping, etc.
• “Blind” detection – the original image is not needed in order to detect the watermark.
• Key protection – it is impossible to detect the watermark without a key.
• Supporting various formats – the program supports the following formats: JPEG, TIFF, BMP, PNG, TGA, MNG, RAS, RAW, JP2, JPC, PCX.
• Supporting small images – it is possible to embed a watermark to an image of 64x64 pixels and larger.
• High performance – the program is written completely in the C++ language, which ensures its high performance.
