Information security in today’s world is very important. For the transmission of confidential info, experts advise encrypting it and transmitting it only through truly trusted communication channels.
However, most of the algorithms that are used in modern messengers are vulnerable to hacking to some degree. If information is intercepted, attackers will theoretically be able to disclose it.
How can you hide a message in a picture?
That’s why, along with encryption, you can use masking textual information with some harmless message. One option is to hide the text inside a picture. No one will intercept a postcard with dogs, and therefore the message hidden in it will remain safe.
How does it work?
The essence of this encryption method is that a part of one file is placed inside another. As we know, any information transmitted electronically is encrypted in a certain way. If the code of one file is correctly embedded in the code of the other, the structure of the second file will not change. Thanks to this it will be possible to use it for its intended purpose.
The image can be opened in viewers and image editors, or sent by email or messenger. The only thing that changes is the size of the file. It’s worth taking this into account.
To embed a message in the image on your own is not a simple task. But there is a special software for this such as steganography applications for Android.
Steganography Master is a great open-source application. You can use this tool to hide your secret data inside an image file. If you have a small amount of data to hide, you can use this tool.
The application allows you to easily put some information in an image so that 99% of people can’t tell that the image has been altered.
It also allows you to hide the information in the image and send it encrypted, store it on your Android device or store it in the cloud.
So how do you decrypt such a message? It can only be done with this application. And if you don’t want someone to be able to decrypt it, you can set a password. And only those people to whom you give the password will be able to do this.

PixelKnot uses open source code and the F5 encryption algorithm. It allows you to insert quite large portions of text information into the image code.
The developers of this software claim that even specialized tools designed to detect encrypted files cannot detect the result of PixelKnot.
PixelKnot allows making the hidden text message to be read-only by those who will be given appropriate access. In order to decode the message, you need to know the secret password.
Users who don’t know it will not only be unable to decode the message hidden in the picture but will not even know that it’s there.
The PixelKnot application gives its users:
- Mathematical security guarantee – the steganographic algorithm of the application uses matrix encryption. This makes embedding more efficient by distributing altered information evenly throughout the file.
- Resistant to attacks – messages created with PixelKnot were tested by special utilities and successfully passed the test.
- Multilinguality – if the language users need is not on the list, you can contact the developers and after a while it will be added.
