Here I am, writing about yet another one of my projects. This time I have decided to work on a program relating to a subject that is both close to my heart and one that some people find difficult to understand – chemistry.
I am thus building a tool to help people understand and solve chemistry related issues, it comes with a periodic table (as shown below) a chemistry calculator as well as some other features. As always I am open to suggestions and help should you wish to contribute either.
I will post developments on this project as I complete or start work on various parts of it so stay tuned for more! (Yes, I did copy the colours from the Wikipedia Periodic Table but I am colour blind so that was the best I could do under the circumstances!)
In an earlier post I said I would explain a little about the the format used in my new data encoder and so here it is.
The images are stored in PNG, not any other type of format, because PNG supports full alpha transparency. The data is encoded by converting the text into binary data and then these are converted into pixels of colour, with the data stored in one of the 4 colour components (red, green, blue, alpha).
Certain operations are then done on this data to make it harder to recover and the remaining spaces are filled in with randomly generated pixels.
I am pleased to announce that the new image encryption tool I was working on is now completed, boasting some new features that I will post about later. I also hope to post about the format, and how the data is stored (though I will keep some of the details hidden to ensure the format remains secure). If anyone wishes to beta test the software then please context me.
But for now I am going to get some much deserved rest. Keep an eye here for more information soon.
I have just been reading a rather interesting article on TorrentFreak about a new law that the US government hopes to pass, for which I quote the title of the post on TorrentFreak.
United States lawmakers have proposed new legislation today that would allow the Department of Justice to take over domain names of websites that promote copyright infringement. The proposed bill would allow for court orders against domestic as well as foreign sites, which could potentially shutter many torrent sites including The Pirate Bay.
What the hell does the US think they are doing? Until now no political body has owned the rights to control the internet on that level, for whatever reason, and suddenly the US comes along and decides they have that right? How is it that the US feels they have the right to decide to impose their laws in other countries? Copyright law does not apply everywhere and it varies greatly from country to country… I fail to see how they can claim to remove a copyright infringing website from a country that may have a different idea of copyright violations.
Someone really needs to slap some sense into the US, they are starting to cross lines that are better left alone. Leave the internet free of political influence or beware the consequences.
Since I now have some more spare time I have been working on a new tool that allows you to securely hide at most 4 pieces of information (each a maximum of 255 characters in length) inside a random pixel image. I am working on ways to use this technique inside real images, but that is somewhat more difficult and it may take a while to perfect, if it works at all.
The image appears to be a random pixel generated image with varying colours, usually with 50×50 pixels in dimension (but this is not required to be so). The image looks something like this:
… And when you open it in the decoder tool you get something like this:
The program is actually quite simple but the way in which the information is stored should make it quite difficult to break. However with the decoding tool I have designed, you need only open the image to retrieve the information. If anyone is interested in hearing more or has some ideas to contribute, please let me know. I will release more information about the system used and so on at a later time when I stabilize the idea and format.
Unfortunately my Future Jobs Fund (FJF) placement has now finished – which is a real shame since it was a really good scheme. So I am now once again looking for a job until the funding for CCC comes through.
I should have more time to post here in the interim in any event.
I’m quite happy to have found my first prime as part of PrimeGrid!
I got the following e-mail this morning:
Congratulations! Our records indicate that a computer registered by you has
