Hiding Files in Images?
I’ve known about Stenganography for some time. And no, it’s not spelled wrong. That’s not Stenography, but Steganography. Two different things. I’ve been thinking recently about all the news items that are talking about privacy erosion and governments around the world passing or about to pass laws to break into your private messages of any kind. And then the above video popped up in my Youtube suggestions. From 2 Feb 2019 no less. Quite Recent. I’ll provide a link at the end of this post, but it’s not the main point of the video. I’m going to take that primitive program’s idea and show how it can be extended, a lot. I’m saying primitive and if you don’t believe that, watch the video. Sigh.
Steganography ( (listen) STEG-ə-NOG-rə-fee) is the practice of concealing a file, message, image, or video within another file, message, image, or video. The word steganography combines the Greek words steganos (στεγανός), meaning “covered, concealed, or protected”, and graphein (γράφειν) meaning “writing”.
I’m not mentioning anything the NSA does not know, but apparently the lawmakers around the world have not called in an expert who has mentioned the science of Steganography to them in their hearings for their new lawmaking regarding Privacy.
Let’s look at what’s happening to Privacy / Encryption around the world.
The Gerbil Siblings
I stopped by the pet store today and they had two gerbils. They are apparently siblings – brothers or sisters? Not sure. I’ll have to do more research to determine their sex. But it looks like they are the same sex, so no little ones.
They get along very nice together. And they are not babies, but look like adolescents – a few months old probably. As you can see here, they are not really young babies.
My gerbil died last night. He looked pretty sick yesterday. No way to tell what happened of course. I got him on May 31, 2012 so I guess it was his time.
I got a new gerbil today. He looks like the previous one – blonde with white markings. He is 3.25 inches long and weights one ounce. Very much smaller than the previous gerbil. Here are some pictures on his first day.
The gerbil has died. Not sure what his ailment was, but he was clearly feeling bad yesterday. There was no obvious problem. One issue might have been his teeth, but careful examination showed that his teeth were fine. They were well trimmed so he had enough wooden clothes pins to chew on to keep them worn down. Not sure what happened.
Since Nov 2010, the gerbil has been a constant companion and friend. Watching my every move, he learned to come to the cage when he heard me in the kitchen or heard the bell from the toaster since it meant that I would be giving him a treat from something I was making for myself.
He learned to run around and through packing tubes next to his cage. He seemed to like to be chased through the tubes.
CutiePetutie [spelling vary] will be missed. But I will get another baby gerbil soon and see whether he learns as much about me as Cutie did.
