Watermark Security

Watermarks are randomly generated sequences of numbers. For this purpose, random number generators are seeded with a key and a sequence of random numbers from the desired distribution is obtained. Marker and detector uses the same key and watermark.

Each Photo Watermarker application has a unique key which is generated at first run. The same key is used through out all life-cycle of the application.

The key is generated based on time and hardware information, so that collusion probability is practically zero. The key is stored in the configuration file in a scrambled way. Since each application is associated with a unique key, new installations will have different keys.

Photo Watermarker introduces a second layer of security to prevent your watermark being discovered by brute force trial and error. For this purpose random spatial localisation is performed. Hence, for watermark discovery one should try all possible spatial combinations in addition to all possible keys, which renders discovery practically infeasible.
