Invisible Copyright Information (Invisible Watermark)

So what is invisible copyright information? You understand your photos will be redistributed and republished without your consent if you share your photography online. If you are a professional photographer or an avid photographer, you are probably also aware of the significant financial losses that creative professionals suffer. Read through to know more information on invisible copyright information.

What are Invisible Watermarks?

Invisible watermarks sometimes referred to as steganography (from the Greek “stenagos”-covered), get their name because they are not readily noticeable to someone who is unaware of their presence.

For those who are “in the know,” this includes secret patterns or symbols that communicate information. In some types of steganography, a picture may have a secret meaning that is “hidden.”

 For instance, an image of one apple on a table conveys one idea, whereas a picture of two apples conveys a completely different message. These are very important invisible copyright information, hidden so they can’t be used without the owner’s permission.

How Do Invisible Watermarks Work?

By gently changing the values in a photograph’s pixel values, invisible watermarks operate. Photographs can have hundreds, millions, or even billions of “pixels” depending on their size.

Pixels are tiny, one-color squares. Three “channels” of red, green, and blue make up each pixel. We can truly create every color that a computer can display by combining different hues of red, green, and blue.

 Rendering every shade of white, black, and gray is also possible by combining only red, green, and blue.

Invisible Watermarks and Text Files

The method won’t work with.txt files since there isn’t any room in an ASCII text file to hide anything.

There is still a place to hide the information so that you can retrieve it later and show that it is accurate and not just a mistake.

It might work if you considered the page of text to be a visual (much like a PDF can, this are invisible copyright information.).

Invisible Watermarks and Images

Invisible Copyright Information

Images have frequently utilized invisible watermarks to establish copyright and show who is the rightful owner of the content. The image file must have enough pixels to accommodate an invisible watermark if one is to be added.

 If not, the watermark will be seen and the image quality will suffer. Because of the large amount of pixel data that invisible watermarks often require, altering a single pixel here and there won’t cause the image to degrade.

This is necessary because the saved file must be duplicated exactly, not a little more or a little less, in order for it to function.

How to Make a PDF Watermark Not Visible

The original file would need to have the invisible watermark added to it by a program before distribution in order to create a PDF with an invisible watermark or to make a PDF watermark not visible.

Alternatively, the protection software would need to ascertain when to insert a dynamic watermark (such as a username) and watermark when it was being read and/or printed.

This is not currently workable. Since there is no capability to dynamically add invisible watermarks, you would have to manually reprocess the identical PDF file for every user, adding a unique identity.

Invisible Watermarks in Social DRM for Ebooks

So-called social watermarking for ebooks is a more contemporary variation of the invisible watermark concept. The dynamic watermarks are both visible and invisible, with the latter being concealed in the document’s code.

Unfortunately, this type of watermark is relatively simple to remove even though it is not immediately evident.

The user can examine and alter the document’s code and filenames because the ebook isn’t protected from alteration in any other way.

 Removing Invisible Watermarks

You must make sure that invisible watermarks endure screen capture, printing, and format changes when employing them. If a PDF document isn’t otherwise secured, they can save it in a different format.

After that, the invisible watermark is gone. There have been plans to develop invisible watermarks so that images can endure conversions from (for example) png to jpg.

But they are less clear about what would happen if images are resized and reshaped or printed before being scanned. Screenshots of images have a different format than the originals and sometimes don’t have the invisible watermark.

Visible Watermarks

When used with safeguarded papers, these prove to be incredibly handy. Since everyone can “see” the watermarks and check to see if they look right, that these watermarks are visible makes them much more secure to implement.

These watermarks cannot be entirely removed by adjusting the view on the screen or the printed page. Visible watermarks have a past as well. They have a strong track record of protecting international agreements, banknotes, and other documents. 

They also offer a reliable method of preventing document forgery, though it is already more difficult to do so with encrypted documents because you have to completely defeat the encryption/decryption algorithm in use.

Invisible vs Visible Watermarks as a Copyright Deterrent

The purpose of creating a secure document is typically to stop “secret” information from becoming available to the public.

The only purpose of invisible watermarking is to conceal another secret within that restricted information.

Because the watermarks are invisible, it does nothing to physically (or digitally) hinder sharing with others and is ineffective as a deterrent. It is only useful for locating a leak’s source after it has already happened when it is too late.

Copyright Infringement Problems

Typically, the goal of generating a secure document is to prevent “secret” information from becoming public knowledge. Invisible watermarking is only used to hide a different secret within that restricted information.

Ineffective as a deterrent because the watermarks are invisible, they have no physical (or digital) influence on sharing with others. It is only helpful for identifying the source of a leak after it has already occurred and it is too late.

In order to establish copyright on content that you want to be available to the wider public, invisible watermarks are the ideal option. For instance, as a photographer who posts images online.


A subset of watermarking known as invisible watermarking uses a digital signature that is integrated into the image to provide security while making the watermark invisible to the unaided eye.

The suggested method adds an undetectable and invisible watermark on any photograph without distorting or degrading the image’s quality.

This invisible copyright information can be very helpful. Using an autoencoder neural network, which has been specifically trained to implant watermarks onto images, is accomplished. T
