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.

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 (eg. 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.
