Blue2Digital has designed Digital Chip Card Technology, or DCCT for short, an innovative, sustainable and functional solution that covers all aspects of copyright and intellectual property protection, primarily in the digital world. It helps us globally and uniquely authenticate digital works that are sold, bought, listened to, read, or viewed and raise the security and credibility of the data to the highest possible level. Nowadays, DCCT stands out as the most reliable, professional and comprehensive way to protect your digital assets.

Digital copyright tags are information embedded in digital products, making them available for secure authentication, recognition, quality control, and distribution across digital platforms such as PDF books and music stores, audio and video streaming services, stock photo sites and online marketplaces. Files containing digital copyright tags can be used as evidence in legal disputes and litigation. Digital chip card technology ("DCCT") utilizes digital signatures, digital barcodes and digital watermarks depending on how and where the digital product in which they are embedded will be used.

The digital copyright tags produced by digital chip card technology are adaptable to the file in which they are embedded and are invisible to the naked eye, while they are inaudible to the human ear. The digital copyright tag must not interfere with the original file in any way. The process of verifying the existence of a digital copyright tag embedded in a file must be publicly available and presented in a way that everyone can understand how it works.

In order for a digital work to be fully copyrighted and uniquely identified, we must undertake a digital copyright protection procedure that consists of several steps:

• Create an encrypted set of files that provide evidence illustrating the progression of the author's work;
• Either digitally sign your authorized work or add a digital barcode to it, depending on what you will be using the work for (check this link for more details);
• Optionally, insert an adaptive, invisible and inaudible digital watermark which cannot be removed regardless of changes to the file representing the authorized work.

Finally, register your work with a copyright protection agency. Files with digital copyright tags embedded in them are available for secure authentication and distribution across digital sales and streaming platforms, or you can use them as evidence in legal disputes and litigation.

In order to round off the process of establishing full copyright and intellectual property protection, we will act towards finalizing the digital product using our two-level protection tool. The first level of protection involves adding a digital signature or digital barcode to the author's work. Digital signature and digital barcode are used to ensure the authenticity of the digital document and the identity of the document owner. Whether it is a digital signature or a digital barcode to be embedded depends on what the work will be used for. On the other hand, if the item is distributed to digital platforms where the version presented to the audience is likely different from the original version created by the author, it may deserve a digital watermark as an additional level of protection for its content.

A digital signature is a digital copyright tag used to ensure the authenticity of a digital document, the integrity of its content and the identity of the document's owner. Any change to a digitally signed file results in an error being reported during authentication. A digitally signed document is usually not intended for the general public, but is available only to a certain group of people (eg within a company), who have the appropriate key to verify the digital signature and are interested in confirming the authenticity of that signature.

A digital barcode is a digital copyright tag used to ensure the authenticity of a digital document, the integrity of its content and the identity of the document's owner. Any change to a file with a digital barcode attached to it results in an error being reported during authentication. Compared to a digital signature, a digital barcode contains a significantly larger amount of data. It can serve as a repository for the author's promotional material, such as a promotional text, a PDF booklet, a personal audio message or a short promotional video. The digital barcode is intended to be inserted into the final product we sell or promote and to help us address our customers in the most personal way possible.

When a digital work is distributed through online sales and streaming platforms, the version presented to the audience is often different from the original version created by the author. It affects file dimensions, format, audio richness, bitrate, color, printing, etc. and reduces the overall quality of the published file. The digital signature and digital barcode themselves do not play any role here, because the information they provide is lost due to changes in the file structure. We need to introduce another tool to ensure data protection and confirm that the quality of the item is still at an acceptable level. The tool is called digital watermarking.

DCCT allows you to insert a digital copyright tag in the form of a digital watermark that cannot be removed regardless of changes to the file representing your digital work. The embedded watermark is made adaptive, invisible and inaudible and does not compromise the quality of the original file in any way. Digital watermarking algorithms involve adding a controlled amount of AWGN (additive white Gaussian noise) coupled with mathematically generated patterns to the digital work. Data protection is based on real-time calculations in both the frequency and spatial domains.

The digital watermark generated by DCCT is robust enough to be unaffected by minor changes to the file. Only if the original signal-to-noise ratio is significantly distorted (that is, too much noise is added to the file), the success of watermark recognition is called into question.

An authentic digital asset, or "ADA" for short, is any asset in digital format, such as images, photographs, PDF files, animated GIFs, songs, videos, movies, e-books, with an embedded digital barcode and stored on a custom built blockchain. The digital barcode provides a globally unique file identifier and copyright protection tool, while the blockchain platform forces hosted digital assets to remain immutable, irreplaceable, irrevocable and available for validation at any time of the day. The creation of an authentic digital asset is driven by a set of innovative solutions featuring digital chip card technology.

Security tokens, consisting of a hash code, an IP address, a public key, and a timestamp, are held responsible for verifying the authenticity and integrity of the data that make up the digital asset. They cannot be changed, removed, ignored or abused in any way, thus guaranteeing the ultimate digital copyright protection.

Yes, you can. Once a file is digitally protected, it is available for download and further distribution.

All types of files can be digitally protected, but our algorithms typically focus on works from the fields of music, photography, film and literature.

Yes, they are. Once a file is digitally protected and published, it is available for public inspection and verification.

No. In fact, each type of file requires a different approach. For example, algorithms for protecting videos and those for PDF files have little to do with each other.

DCCT algorithms for digital protection are by all means innovative and unlike any existing technology.

Yes, it is highly recommended to do so. There are some verified channels over which content authors have no control. Likewise, there are some other channels that we assume are managed by the authors themselves, but have not yet been verified. In any case, regardless of whether your channel is verified or not, proof of the authenticity of the content posted on it is necessary to provide your subscribers and random visitors with a simple and reliable content verification tool. This is possible with the help of algorithms in the way we develop them. We cannot vouch for tools and solutions introduced by others.

Everything that's been said about YouTube also applies to social networks. You need to enable your social media followers to verify the authenticity of the content you post and provide them with an easy and reliable tool to use in the verification process. This is possible with the help of algorithms in the way we develop them. We cannot vouch for tools and solutions introduced by others.

Yes, you can. We even advise that the organizations and associations themselves insist that the works approved by their members be digitally tagged and protected. Moreover, we recommend that digital copyright protection in the form of inserting digital copyright tags becomes a legal obligation.
