What is digital fingerprinting and why is it so important for protecting copyright and building up a genuine relationship with your consumers, subscribers and followers?
Are digital watermarks embedded virtually or physically?
The algorithms developed by our company enable digital stamps to be physically embedded in files and we believe that this is the only way to properly manage the watermarking process. Algorithms that do stamping according to the principle of determining the so-called "hash values" have very limited practical use, while the algorithms we have developed are not bordered by such restrictions. Complete and comprehensive digital watermarking solutions are recommended by all means.
After stamping, can we get our digitally stamped files back?
Once digitally stamped, the files can be downloaded and distributed further on. You are also guaranteed to get the corresponding "certificate of ownership" with a digital signature. The certificate is supposed to prove that you have stamped a particular file at a certain moment in time and is available for public inspection and verification. Furthermore, if you stamped an image or an audio file, you are also guaranteed to get a second-level protection of the original digital file in the form of a private fingerprint key. This key is not publicly available and is to be delivered via email exclusively.
Files that you stamp by using our watermarking tools are available for further distribution to all digital platforms, PDF books and music stores, audio and video streaming services, stock photo sites and online marketplaces.
You can have a look at the screenshots representing different stages of data watermarking. Please also visit our step-by-step guide on how to add a watermark to your image, audio, video, animated GIF or PDF file.
What types of files can be digitally sealed?
All types of files can be digitally sealed, except that our watermarking algorithms are focused on works in the fields of music, photography and literature, because we find these catagories the ones most worthy of attention.
Are digital seals available for public verification?
Yes. You need to create an account first, which is manadatory for avoiding abuse. Then you can submit the watermarked file for recognition (it's the reverse of watermarking). The file (image, audio, video, animated GIF, PDF) can be one of yours, or you could have found it on the Internet and now you want to verify its credibilty by extracting the digitally embedded watermark (if any).
And if you just want to verify the validity of one's digital signature or the authenticity of one's certificate, you do not need to create any account - it can be accomplished by using our certificate verification tool.
Are there the same algorithms applied to all types of files?
When it comes to files from the same categories, the algorithm is the same, but the procedures vary a lot for files coming from different categories. For example, extracting the watermark data from audio files is mathematically much more accurate than extracting the watermark data from images. On the other hand, unlike removing the watermark data embedded in audio files, it is almost impossible to obliterate or remove the watermark data embedded in images.
Video files are a combination of audio files and images and are certainly the most complex to watermark. Things work differently for animated GIF files, as they are made up of moving images and are very exact by default. Same goes for PDF files and the corresponding watermarking algorithms, which makes both GIF images and PDF documents easier to deal with.
I have a verified YouTube channel. Do I have to digitally stamp my videos too?
To understand the need of watermarking the content you upload to YouTube, put yourself in the shoes of your channel visitors for a moment. You will notice the following:
1. There are some cases of verified channels over which the authors (i.e. performers, composers, bands, record labels etc.) have no control, and therefore the content being uploaded does not guarantee its own authenticity.
2. There are some instances of channels that have not been verified (not yet at least), but which we assume they are managed by the authors themselves. Still, we need a proof of it.
3. The channel is verified and the channel content is confirmed to have been provided by the author himself. The question is, how are your channel subscribers supposed to believe that the uploaded version of the motion picture, video clip, television show etc. is not a copy, but that it really comes from an authentic recording session (whether in a studio or live, filmed by a movie camera or recorded by a video camera)? An audio or video file could have been converted or edited five or six times before it's posted online and such a derivation certainly cannot be deemed an authentic version.
So, if you have your own verified YouTube channel, having your content digitally watermarked before its public release is more than welcome, for the sake of your channel's subscribers and your own sake too.
I have a verified Facebook/Twitter/Instagram profile. Do I have to digitally stamp the content that I post on my profile?
Everything we said about YouTube goes for the social media as well. You have to enable your social media followers to verify the authenticity of the content that you publish and provide them with a simple and reliable mathematical tool that will be used in the verification process. This is possible with the help of mathematical algorithms the way we develop them. Other companies and developers may have others of their own, but these are the ones we as a company guarantee.
Does a digital watermark mean the same thing as a digital signature?
Digital watermarking and digital signatures are two different things, but they are often misinterpreted as one of the same procedure. True indeed, they do have one important common goal and it pertains to providing evidence of the authenticity of a copyrighted work. Digital signing has one advantage and that is the ability to be publicly verified, while stamping mainly depends on a particular database and a mathematical calculation not publicly available.
Stamping, however, has one huge advantage over signatures introducing the universality of the verification process. A digital signature can only be applied to the original file and any further changes to that file in terms of converting to another format (e.g. from PNG to JPG, WAV to MP3, MP3 to AVI etc.), changing resolution, bit rate, bit depth or file size, make the digital signature unusable. On the other hand, the digital sealing implementation is not disrupted by these obstacles (it at least pertains to the algorithms we have developed). It will be no problem to extract the stamp from the watermarked file even if the file is to change its format, resolution or size.
For those using our watermarking tools, the digital signature comes free of charge in the form of a certificate of ownership paired with the corresponding watermarked file.
Does a digital seal have to be invisible, inaudible and noiseless?
Speaking of the digital stamps designed by our watermarking tools, the answer is yes. Our watermarks are inconspicuous and invisible to the naked eye, while the human ear cannot hear them. A watermark must not obstruct the original file in any way. Only a mathematical calculation can prove its existence and it must be available to anyone who wants to verify the authenticity of the seals embedded in the files. The calculation is very complex, but it has to be presented in such a way that is acceptable for everyone to understand how it works.
Can I have my digital seal embedded within a barcode?
QR code is a two-dimensional barcode that contains a large amount of data and can be quickly and easily encoded, generated or created, as well as decoded, read or scanned. Storing data within a barcode image is an easy and secure way to provide a potential customer with accurate information about a digital product. Our free online app will help you create a QR code containing information about your product and the corresponding digital signature and get it distributed to your customers, resellers or affiliates. Combining barcodes and digital fingerprints is by far the best way for you to put your products up for sale.
How secure and reliable is your database?
The data is permanently backed up and kept safe offline with the files being copied and archived and ready to be restored, if necessary. We are also working on how to diversify our database through a blockchain and make it as verifiable as possible.
If there's any additional noise to be added to the watermarked file, can the watermark data still be recognized (extracted) from such a noisy file?
It depends on the amount of noise added to the file. The digital watermark must be built solid enough not to be affected by normal changes to the file. If the original signal-to-noise ratio is significantly disturbed (that is to say, if the noise is set too high), the watermark recognition process will certainly be compromised.
If I am a member of a copyright organization, or an association of writers, photographers, musicians, or filmmakers, can I still have my works fingerprinted?
Absolutely. We even advise that organizations and associations themselves should insist on having the works authorized by their members digitally sealed. Furthermore, we'd recommend that inserting digital stamps should become a legal obligation.
