ESSENCE OF THE INVENTION

[0004] The technical problem that the proposed solution aims to solve is the creation of a computer-implemented method for protecting and identifying a precious stone.

[0005] The technical result of the claimed technological object is to increase the accuracy of gemstone identification, as well as to ensure absolute identity between the original gemstone and its reference digital copy. It should be noted that the creation of a protected reference digital identifier for the gemstone ensures the highest identification certainty and, consequently, identification accuracy, since the reference three-dimensional model is protected from counterfeiting. Furthermore, the claimed method for protecting and identifying the gemstone does not require physical interaction with the gemstone, further enhancing its protection from external factors.

[0006] The claimed technical result is achieved by implementing a computer-implemented method for protecting and identifying a precious stone, based on an original protected three-dimensional model of the precious stone, which includes the following stages: generating a reference protected digital identifier of the precious stone by creating a digital copy of the precious stone, based on a non-fungible token; performing an accurate three-dimensional scan of the original precious stone, wherein the information attributes characterizing the original precious stone, as well as the exact three-dimensional model of the original precious stone, are loaded into its digital copy, wherein the digital copy of the original precious stone, with the aforementioned information attributes, as well as with the exact three-dimensional model of the original precious stone, is registered in a distributed data registry;When the need arises to confirm the information attributes of a precious stone, as well as to identify it, a three-dimensional scan of the precious stone to be identified and checked for originality is performed, and its three-dimensional model is obtained; the obtained three-dimensional model of the precious stone is compared with the original three-dimensional model that was initially loaded into the protected digital identifier of the precious stone; based on the results of the comparison of the three-dimensional models, the precious stone is identified or not identified.

[0008] In a particular embodiment of the claimed computer-implemented method, the information attributes characterizing the precious stone are, at a minimum, the color of the precious stone; the mass of the precious stone; the origin of the precious stone; the treatment of the precious stone; the purity of the precious stone; and the quality of the cut of the precious stone.

[0009] In a particular embodiment of the claimed computer-implemented method, a digital copy of a gemstone, implemented on the basis of a non-fungible token and containing an exact three-dimensional model of the original gemstone, as well as information attributes characterizing the gemstone, is confirmed using an electronic digital signature of the gemstone manufacturer and is registered in a private distributed data registry.

[0010] In a particular embodiment of the claimed computer-implemented method, the identification of a precious stone is carried out on the basis of a comparison of three-dimensional models according to the following criteria: figure volume, number of facets, facet pattern, facet angles and areas of each facet, as well as on the basis of a comparison of quantitative and physical information attributes characterizing the precious stone, namely: the color of the precious stone; the mass of the precious stone; the treatment of the precious stone; the purity of the precious stone. DETAILED DESCRIPTION OF THE INVENTION

[0011] The following detailed description of the invention includes numerous implementation details intended to provide a clear understanding of the present invention. However, one skilled in the art will readily appreciate how the present invention may be utilized with or without these implementation details. In other instances, well-known methods, procedures, and components have not been described in detail to avoid unnecessarily obscuring the features of the present invention.

[0012] Furthermore, it will be clear from the foregoing description that the invention is not limited to the embodiment described. Numerous possible modifications, changes, variations, and substitutions, while preserving the spirit and form of the present invention, will be apparent to those skilled in the art.

[0013] This technical solution enables the most confident, efficient, and accurate identification of gemstones, as well as the protection of reference data characterizing the gemstone in digital format. Specifically, the proposed technical solution prevents fraudulent actions during gemstone identification and significantly increases the reliability and authenticity of information regarding and characterizing the original gemstone.

[0014] Currently, the jewelry industry is a huge playground for scammers and unscrupulous sellers. The most common fraud in this industry is direct counterfeiting of precious stones. It's also common for information published and posted by jewelry manufacturers and / or sellers on official websites to be inaccurate, and these websites themselves can often be spoofed by phishing scammers. In most cases, it becomes very difficult to clearly identify a precious stone with the stated quality attributes.

[0015] It's worth noting that jewelry is often used as an investment vehicle. However, securely purchasing, selling, identifying, storing, and physically transporting precious stones can be quite challenging.

[0016] The claimed technological object significantly improves the security and reliability of information characterizing and identifying a precious stone. The claimed invention also addresses a number of issues related to the direct physical protection of precious stones from counterfeiting by creating a secure reference digital identifier for the precious stone. Creating a secure reference digital identifier for a precious stone is crucial, as the reference information must be reliably protected to prevent fraudulent activity.

[0017] To achieve the aforementioned positive technical effects, the first stage of the claimed method involves creating a digital copy of the gemstone based on a non-fungible token. A digital copy is a virtual copy of a physical object that accurately recreates the physical object in a virtual environment. A non-fungible token (unique token) is a type of highly secure cryptographic token, each instance of which is unique (specific) and cannot be replaced or substituted by another similar token. A non-fungible token is a cryptographic certificate of a digital object, which is designed to be transferable via a mechanism used in cryptocurrencies. Thus, information characterizing the gemstone is generated based on cryptographic tokens, each instance of which is unique (specific) and cannot be replaced or substituted by another similar token.

[0018] A digital copy of a gemstone contains at least the following information attributes necessary for identifying the gemstone: gemstone color; gemstone mass; gemstone origin; gemstone treatment; gemstone purity; gemstone cut quality; figure volume, number of facets, facet pattern, facet angles; area of ​​each facet.

[0019] However, this information may not be sufficient for the unambiguous and absolute identification of the gemstone.

[0020] To ensure accurate and high-quality subsequent identification of a gemstone, a precise 3D scan of the original gemstone is performed. In one embodiment, the gemstone can be scanned using Scanox CAD equipment from OGI system or other equipment. The resulting 3D model of the original gemstone can be generated in STL or another format. The 3D model of the gemstone is loaded into its digital copy. Thus, the digital copy of the gemstone additionally contains an accurate 3D model of the gemstone.

[0021] The resulting three-dimensional model of the original gemstone, in turn, contains at least the following precise quantitative indicators of the gemstone: the volume of the figure, the number of facets, the pattern of the facets, the angles of the facets; the area of ​​each facet.

[0022] In this way, a secure reference digital identifier of the original gemstone is created, containing all the necessary information for confident identification.

[0023] A digital copy of the original gemstone, containing the aforementioned information attributes, as well as an accurate 3D model of the original gemstone, is registered in a distributed ledger to prevent fraudulent use of the gemstone's reference digital identifier. This step is crucial because information registered in a distributed ledger cannot be counterfeited.

[0024] In a specific implementation, to prevent the imitation of the original gemstone manufacturer and the falsification of information (information attributes) published by the gemstone manufacturer, a digital copy of the gemstone, implemented using a non-fungible token and containing the information, is verified with the gemstone manufacturer's electronic digital signature, registering information about the gemstone's authenticity and the validity of its digital copy in the manufacturer's distributed data registry. A digital signature is a cryptographic mechanism used to confirm the authenticity and integrity of digital data.

[0025] Information that allows for the identification of a gemstone and its transparent and reliable characterization is essential. The proposed technical solution enables a significant level of information security, as data registered in a distributed ledger cannot be falsified. The proposed technical solution enables the unambiguous identification of a gemstone and protects it from counterfeiting, as a digital copy of the object becomes a protected reference digital identifier of the physical object, carrying detailed and reliable information about the gemstone.

[0026] Thus, due to the decentralized topology and cryptographic mechanisms, malicious manipulation of information becomes extremely difficult, and the information itself remains accessible to all identified participants.

[0027] In a particular embodiment of the claimed computer-implemented method, a protected reference digital identifier of a precious stone is generated at the stage of production of the precious stone.

[0028] Furthermore, when the need arises to confirm the information attributes of a precious stone, namely to confirm all declared quality indicators, it becomes possible to accurately identify the precious stone by comparing the declared quantitative quality indicators with the actual ones.

[0029] To implement identification, a precise scan of the gemstone to be identified is performed. In a specific implementation, at least the following information is obtained: the volume of the figure, the number of facets, the facet pattern, the facet angles, and the area of ​​each facet.

[0030] In one embodiment, scanning of the gemstone to be identified can be performed using Scanox CAD equipment from OGI system or other equipment. The resulting 3D model of the gemstone to be identified can be generated in STL format or another format. In one embodiment, comparison of the 3D models is performed using Scanox CAD equipment from OGI system.

[0031] In a specific implementation, to increase the level of identification confidence, the following physical parameters characterizing the gemstone to be identified are additionally collected: gemstone color; gemstone weight; gemstone treatment; and gemstone clarity. Based on the collected information, it becomes possible to accurately identify the gemstone by comparing 3D models and the gemstone's quantitative parameters with the quantitative parameters contained in the reference secure identifier.

[0032] In one embodiment, to ensure the most accurate identification, the comparison of quality information and three-dimensional models must be carried out, at least, based on the criteria of: figure volume, number of facets, facet pattern, facet angles and areas of each facet, as well as based on a comparison of quantitative and physical information attributes characterizing the gemstone, namely: color of the gemstone; mass of the gemstone; treatment of the gemstone; purity of the gemstone.

[0033] In one embodiment, a comparison of the reference three-dimensional model, as well as the information attributes of the original gemstone, with the three-dimensional model and the information attributes of the gemstone to be identified is performed by means of a computing system.

[0034] Taking into account all the indicators, for a gemstone to be successfully identified, a match across all criteria must be at least 99.5%. With a similarity of 99.5% or greater, a gemstone can be unambiguously identified as genuine and corresponding to its reference digital identifier, as well as all the stated quality information attributes. Otherwise, the identified gemstone may be deemed non-genuine and the identification procedure will fail.

[0035] It should be noted that the stated technical solution is safe for the precious stone and does not involve physical intervention or hardness testing during identification.

[0036] At least one physical computing system capable of providing the basic data processing necessary to implement the claimed solution generally comprises components such as one or more processors, at least one memory, data storage, input / output interfaces, input means, and networking capabilities. When executing machine-readable instructions contained in the random-access memory, the device's processor is configured to perform the basic computing operations necessary for the operation of the device or the functionality of one or more of its components. The memory is typically implemented as RAM, which is loaded with the necessary software logic to provide the required functionality. When implementing the proposed solution, the memory capacity required for its implementation is allocated. The data storage medium may be implemented as an HDD, SSD, RAID array, network storage, flash memory, etc.The tool enables long-term storage of various types of information, such as the aforementioned files with user / passenger data sets, databases containing records of time intervals measured for each user, user identifiers, etc. The interfaces are standard means for connecting and operating peripherals and other devices, such as USB, RS232, RJ45, COM, HDMI, PS / 2, Lightning, etc. The choice of interfaces depends on the specific design of the device, which may be a personal computer, mainframe, server cluster, thin client, smartphone, laptop, etc. A keyboard can be used as a data input device in any embodiment of the system implementing the described method.The keyboard hardware can be any standard: it could be a built-in keyboard used on a laptop or netbook, or a separate device connected to a desktop computer, server, or other computing device. The connection can be either wired, with the keyboard cable connected to a PS / 2 or USB port on the desktop computer's system unit, or wireless, with the keyboard exchanging data wirelessly, such as via radio, with a base station, which is directly connected to the system unit, such as a USB port. In addition to the keyboard, other input devices may include a joystick, display (touchscreen), projector, touchpad, mouse, trackball, stylus, speakers, microphone, and so on.Networking tools are selected from a device that provides network data reception and transmission, such as an Ethernet card, WLAN / Wi-Fi module, Bluetooth module, BLE module, NFC module, IrDA, RFID module, GSM modem, etc. These tools facilitate data exchange via a wired or wireless data transmission channel, such as a WAN, PAN, LAN, Intranet, Internet, WLAN, WMAN, or GSM. The device components are connected via a common data transmission bus.
