Online serial book - The Cliff Nest

Today is a great day. I just started the publishing of my interactive serial
book .

The book is a sci-fi story that integrates cybersecurity challenges as interactive efforts for the readers.


If you don't want to participate in the challenges you can still read the book. Just be patient until the end of the challenge to read the challenge resolution as part of the story.

Read the current chapters and return regularly. New chapters at least weekly

This poses an interesting challenge -  how survivable is steganography in filters? This also gave us a great reason to publish another set of pictures (albeit cropped) of Lena Söderberg ;) Here is our original image Proposed Counter-Steganography System The filter system will need to be cost-effective, minimally intrusive and not prone to error. Since there may be many different steganography alghorithms, the filter system should not try to read such messages. Doing so will require an entire farm of filter servers. Instead, the systems will resort to a much simpler mechanism: Modify all passing images so that the original hidden data is compromised. Use only minute c
