Inspiration

We enjoy taking pictures, however it is a concern to us that the pictures can be used by other people without our permission, but we also don’t want to put a normal watermark that may affect the appearance of the pictures. Hence, how do we balance the trade-off between the appearance and the copyright?

What it does

How we built it

IT’S STRAIGHTFORWARD! We built an application that adds an invisible watermark to our pictures.

We took the advantage of the fact that frequency domain is hard to be decoded since it’s impossible to know which frequency the invisible watermark is on. It’s also generally impossible to detect the watermark without damaging the original image.
