What is UATAG?

UATAG (unique authentication tag) — it is patented solution for product originality verification and counterfeit protection based on a two-level authentication technology: physical — the uniqueness of the broken glass cracks, and digital — blockchain.

How can UATAG help my business?

If you are a brand owner concerned about product diversion, counterfeit and need an effective tool to determine authenticity, UATAG will meet these needs.

How UATAG looks?
How UATAG works?

1. Item-level tagging

Manufacturer attaches the UATAG identifier on each product item as it’s made. Each label consists of:

  • Glass plate with unique crack pattern — it is a kind of product fingerprint,
  • Unique serialized alphanumeric product reference number for each tag,
  • Individual QR code that serves as a link to the individual tag image page on the UATAG website.

2. Real-Time visual product authentication

A regular Smartphone equipped with any QR scanner app can be used to verify if the product is AUTHENTIC or FAKE. As customer scan the QR code he accesses the base and sees the image of this particular tag from the secure database. Compares glass pattern with the one that is attached to the product. If they match — the product is original!

UATAG allows a consumer to verify the authenticity of origin of the product prior to purchasing it for an unlimited number of times, eliminating the possibility of erroneously identifying the counterfeit product as genuine. Thus, he can make a conscious decision about the purchase and is sure of the originality of the purchased goods.

Why UATAG fingerprint is so unique?

UATAG product identifier is made of a plate of glass, in which the unique glass pattern is formed by cracks and plays the role of product fingerprint. Due to the unique physical properties of glass, the position, shape, and size of the glass cracks are completely unpredictable and non-reproducible. It is impossible to make two identical crack patterns. Glass always has internal tensions occurring in the process of glass production. When a plate of glass is mechanically damaged, the cracks that form in it will follow the vectors of the compression and stretching tensions. This allows to create a unique crack pattern, that can not be replicated. Never!

Therefore, each UATAG product identifier can protect your brand with the highest level of security.

Why the glass cracks are completely unpredictable and non-reproducible?

UATAG invention is based on known physical properties of amorphous glass material. The essential property of glass required for the implementation of the invention is the fact that glass always has internal tensions occurring in the process of glass production. The rapid cooling of heated glass results in that its outer layers cool faster than inner layers. The difference in temperature occurs as a result of the low thermal conductivity of glass. In materials with high of thermal conductivity, such as metal, the outer and inner layers cool down almost simultaneously and the temperature difference between them is negligible.

Uneven cooling down of the outer and inner layers of glass results in the occurrence of compression and expansion tensions. When the glass is fully cooled down and the temperature of different layers of glass is aligned, the tensions that occurred during the process of cooling down remain.

Inner tensions occur in the glass in the course of the transition of its state from elastic to brittle, i.e. when the glass particles gradually lose their mobility, up to the moment when the movement of the glass particle virtually reaches zero.

In the course of cooling down, the temperature in the outer layer of glass will reduce considerably faster than that of the inner layer. During the first moments of the process of cooling down, while plastic deformations are still possible, the outer layer reduces in volume. At the same time, the inner layer remains flexible and occupies the same volume as before. When the inner layer cools down further, it also seeks to shrink but meets strong resistance from the outer inelastic membrane. If there was a possibility, the inner layer would separate from the outer layer forming a gap between them. However, as the inner layer cannot come off in a cooled state, it is forced to take somewhat larger volume than would correspond to its temperature. This results in stretching tensions within the inner layer and compression tensions in the outer layer, as it is pulled inwards by the inner layer.

When a plate of glass is mechanically damaged, the cracks that form in it will follow the vectors of the compression and stretching tensions mentioned above. This creates a unique crack pattern in the plate.

Thus, the invention is based on the unique pattern of cracks in material, which becomes visible due to the destruction of material and optical refraction of light.

Is it possible to distinguish one glass pattern from another visually?

The authentic origin of the product is verified by visually comparing the unique crack pattern of the product identifier with its electronic representation obtained from the database on the screen of customer's smartphone.

The resolution of the human eye is about 3000 dpi. For comparison, computer screens have resolutions between 72 dpi and 105 dpi. Therefore, in distinguishing small parts of the image details (the cracks), the human eye wins to scanners and other devices. So, it is easy to verify the authenticity of origin of the product without any specialized equipment or software.

Example: Can you find two identical glass patterns?

How to verify the authenticity of origin of the product with UATAG?

Verification of the authenticity of origin of the product is performed by a visual comparison of the unique crack pattern of the product identifier itself with the electronic reproduction of the crack pattern obtained from the database by the unique QRcode of UATAG product identifier, namely by placing the product identifier side by side or against the electronic reproduction of the product identifier obtained on the screen of a device.

How UATAG's solution is detected? Do I need special devices?

What are the benefits of using blockchain?

A blockchain – is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data. A blockchain can serve as "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which needs a collusion of the network majority. This makes blockchains potentially suitable for the recording management activities, transaction processing, documenting provenance, or traceability [Wikipedia].

Blockchain technology is highly protected against tampering and processing, and reliably supports a growing number of digital records. Working with blockchain, we get the most stable digital registry, reliable data synchronization and protection against substitution of data as a result of attacks.

Can the QR code and/or a serial number be copied?

Yes, it is possible to copy QR code and a serial number, but they are only an addition to the basic protection. The main role here is played by glass cracks. It is impossible to duplicate crack pattern due to the glass unique properties.

Together: plate of cracked glass + QR code + serial number form an anti-copy, highly secure anti-counterfeit solution.

Is it possible to break, damage or to cause additional cracks on the glass plate?

It is almost impossible, because, the glass plate is placed into a protective case that prevents it from the physical damage. In any case, we do not exclude such possibility, because nothing is safe from intentional damage. If necessary, we can offer an ultra-protected enclosure tag, which will be additionally covered with a non-breakable tape.

Is it possible to tear UATAG from the original product and stick it to the fake.

It is impossible. The UATAG is tamper evidence adhesives and one–time use only. The total transfer security label made from PET with release glassine paper. Exterior appearance unchanged, no trace when removed from the applied objects. Any attempt to remove it, will cause the face material damage, adhesive residue would be attached on the products, and the hidden words will be attached on the products. We can meet our customers' requirements and make the special edition mould.
