The internet is a place where people can stay connected to each other. If we look back to early 1900s, who would have thought that one day, we will be able to send images and pics of ourselves and places to almost anyone in this world so easily, without any form of hard prints of them. Then came early 1990s, where the internet started to develop. When web 1.0 came into use.

Web 1.0 marked a new thought of this whole world. Anyone could write anything on the web, which can be accessible to anyone on the web. It was a huge step to develop the human civilization. The years it took to the first printing press is much much higher than the time it took to come to email.

With the increase in technology, the needs and demands also increase... Everything has some faults, we just need to continue working to make it better. Thus, next comes the idea of Web 2.0.

Earlier, in Web 1.0, we could only have static pages on web, to display some kind of information. As a result, a normal person could not publish their information, upload something onto servers and display them as per the needs. After few years of evolution, then came Web 2.0, which changed the whole system. We could now, upload things as well on the internet and provide some information.

The age of Web 2.0 gave us the present world of Social Network, we are living in. In 2004, Mark Zuckerberg created Facebook, that is probably the most innovative thing I could give an example of to explain Web 2.0. Now we know how big company Facebook has become... Oh sorry, I had to say, how big company Meta has become. And here comes another concept of the internet, the Web 3.0...

Currently we are living in an age of Web 2.0 (when this post was published). And if you are in technical fields, you must have heard of Web 3.0 in current years. If you want to know about Web 3.0, scroll down... Because, I went a lot out of topic already.

So, the title of this post is about giving access to personal information via images. So, as I explained you that currently, we are living in Web 2.0. It also has some flaws. Like, every information we are uploading on internet is stored on a server somewhere. So, anything is not completely secure on the internet. 

If you are aware with some Image sharing websites, I might not take their names, they use a concept to share your images. That is, Exchangeable Image File Format (EXIF). "It is metadata contained in an image file, and although it varies among devices, it can provide valuable information such as the make and model of the camera that took the image of a system, as well as whether an image was altered with a graphics program. EXIF data also often will have a date and timestamp of when the image was taken or altered. There are several EXIF formats; therefore, the data can vary slightly. Also be aware that not all devices will propagate all the data."

Well, I guess the above sentences are a bit confusing, so simply, EXIF files are those data files that store your personal information. And, as I talked about the concept used by Image sharing websites, as we upload an image, these data are also stored with it.

Although, some social media platforms like Fb, Instagram say that they remove this EXIF data from the image. But, the question is you can't trust anyone on the internet. Because, remember, if you are not paying for anything, then you are the product for them. And, they are even alleged that they sell the data to third party apps.

Let me tell you about an interesting story...

John McAfee, of course, the founder of anti-virus company McAfee. And the authorities in Belize have named John McAfee as a “person of interest” after one of his neighbors was found shot dead. He used to tell people on the internet about his escapades via blogging. But he did a mistake. He uploaded a photo on the blog. But, the EXIF data revealed his location to the police.

John McAfee was caught because of this EXIF file.

I made this article, because lot of you might not be aware of this thing.

So the question is, how can you delete these EXIF data before uploading a file? Well, there are a lot of softwares in the market that help you remove this file. You can use them before uploading any pic on an image sharing website.

Also, tell me if you want me to make a free software to remove the EXIF files from your photos in the comments below. And you can even contact me via email... Contact

So, as I told you to explain about Web 3.0 at last. So, you must have heard Torrent browser. If I explain you its working, it would be a typical thing to understand. If I explain you in simple, then unlike what we normally have a structure of an Application, Torrent uses a different approach. The normal Web App send the data to a server. But Torrent is peer to peer. Means, there is a temporary connection between the client and the other person. If you want to go in deep, you can read many articles on web about "Torrent working".

So, the Web 3.0 uses that concept. The information will not be stored on any server anywhere. So, this will make the internet a little more secure. But since, it is not that easy to develop that kind of structure in few years, the technology will take time to come in use.

So, I think that's it for the post. And this might be the first post of this month and the last post of this year, one day before Christmas. So, Merry Christmas and Happy New Year to all. Also Reader, tell your friends that I wished all of them too...
