The present invention relates to authenticating physical tags using NFTs, and more particularly, the present invention relates to a system and method for managing paired physical tags and digital NFTs.
Non-Fungible tokens have become quite popular in the digital world and have been used by artists, producers, and the like for a variety of digital products, such as paintings, photographs, songs, stories, and the like. The usefulness and authentication of ownership provided by the NFTs have been proven beyond any doubt.
There have been efforts in the art to use digital NFTs to authenticate ownership of physical articles, especially luxury and limited collection articles. Examples of such articles include costly paintings, limited shoe collections, and the like. Typically, the NFTs are minted for each article and a certificate showing the same is provided with the article. Physical tags that can be attached to the article informing about the NFT are also known. However, such methods suffer from several drawbacks and limitations. The primary drawback is the lack of means to authenticate the certificate or physical tags. The physical tags are coupled to the article; however, these cannot be verified.
A need is therefore appreciated for a system and method for authenticating/verifying the physical tags associated with digital NFTs.
The term physical tag is also referred to herein as the physical NFT or pNFT. The digital NFT is also referred to herein as NFT or dNFT.
The following presents a simplified summary of one or more embodiments of the present invention to provide a basic understanding of such embodiments. This summary is not an extensive overview of all contemplated embodiments and is intended to neither identify critical elements of all embodiments nor delineate the scope of any or all embodiments. Its sole purpose is to present some concepts of one or more embodiments in a simplified form as a prelude to the more detailed description that is presented later.
The principal object of the present invention is therefore directed to a system and method to verify and certify the origin and authenticity of a physical tag based on its associated/paired digital NFT.
It is another object of the present invention to ensure that the current ownership of the physical tag and dNFT are the same and unique.
It is another object of the present invention that the system and method can be versatile by adapting to different blockchains and wallets.
It is still another object of the present invention that the link between creator and object can be maintained.
It is yet another object of the present invention to provide services based on the level of authentication and ownership.
It is a further object of the present invention to provide access to social groups, forums, events, and the like based on the current and past ownership.
It is still a further object of the present invention that the information can be shared based on the physical NFTs.

Disclosed are a system and method for managing a paired physical tag and a digital NFT. The disclosed method allows for verifying the physical tag based on the paired/associated NFT. The disclosed method can authenticate the link between the creator and the physical tag. The physical tag can be applied to any article for which the NFT is generated.
Generally, a creator can create an NFT for a physical article. The physical article can be anything, such as a painting, garment, footwear, timepiece, watch, and the like. It may be desirable that the NFTs are generated for limited availability products, such as precious paintings, limited collection shoes, and the like. The creator of the NFT can be the manufacturer of the article, a seller, or an owner of the article. The creator can create the NFT through the disclosed system. Alternatively, any crypto wallet and blockchain system can be used to mint the NFT. In such a case, the information about the NFT can be received by the system. The creator can use anything digital related to the article to create the NFT, such as a photograph of the article. For example, a photograph showing a shoe from a collection that has further details such as the tenth shoe in a collection with a logo and like can be used to create an NFT. While creating the NFT, other details of the article and of the manufacturer of the article can also be added. The NFT also contains an unlockable content feature in which a UUID and encryption keys (explained later) can be stored.
When the NFT is minted by the creator, the contract and/or wallet address(es) of the creator and the NFT token ID is published in the public domain and is searchable. The minting of NFTs and searching of such transactions is well known in the art. The disclosed system can add such transactions including the contract and/or wallet address(es) and the token ID in a quarriable database, and any such database is within the scope of the present invention.
The disclosed system can also provide for configuring the physical tags based on the NFT to be associated with the physical tag. The physical tag can be applied to the article in one of the many ways. Preferably, the physical tag can be applied in a tamperproof manner. Also, depending upon the article to which the physical tag is to be applied, the physical tags can be made durable. For example, the physical tag for a shoe may be more durable than the physical tag for a painting. The physical tag can include memory for storing information, wherein the physical tag and the memory may support suitable encryption. Preferably, the physical tags may support the hardware level of encryption. The physical tag may also include suitable circuitry that allows writing information to the memory and allows an external device to read the information from the memory. For example, a suitable NFC/RFID chip may be integrated into the physical tag and an external NFC device can read the information from the physical tag. Moreover, the physical tag can be applied to the article before or after getting configured by the system.
The system can have information about the NFT including the contract and/or wallet address(es) of the creator of the NFT, the token ID of the NFT, and the UUID stored with the NFT, and such information can be used to configure the physical token that is applied or is to be applied to the article for which the NFT is generated. The system may receive such information from the minting platform or the creator. The system can store the information in the physical tag such that it can be accessed by an external device, such as a smartphone. Preferably, the UUID can be stored in an encrypted form. UUID can be a unique code made from alphabets, numbers, symbols, and the like, and can be of any length. For example, the UUID can be randomly generated by the system. It is preferable that the UUID can be of such length and can include alphanumeric characters that can be compatible with the NFT and could be copied and pasted using a clipboard of any external device such as a smartphone. A suitable example of encryption includes PGP encryption. The system may have the required keys to decrypt the UUID and read the same from the physical tag. In certain implementations, the encryption can be hardware-based to prevent duplication of the physical token. The UUID can be contained within the physical tag in the encrypted form, and a copy of the UUID along with the private key used for encryption can be received by the system and the same can be stored in the unlockable section while minting the NFT. Thus, the copy of the UUID and the private key may be only in the NFT and only the current owner of the NFT has access to them. The system may not store the same i.e., the UUID and the key.
A user who can be the creator of the article, the current owner of the article, or any user in possession of the article can check the pairing of the physical tag with the digital NFT using the disclosed system. The user can verify the physical tag based on its associated NFT and the link between the creator and the article. The user can use any computing device, referred to herein as a user device, provided the user device is compatible to read the physical tag. For example, for the physical tag having the NFC, the user device must be NFC equipped. Examples of user devices include smartphones, smart watches, tablet computers, and the like.
Referring to
Through the first screen, the user can access a host of services wherein the list of such services can be provided on the screen.
The user can also be provided with an option to further verify that the user has the article and that the user is the current owner of the article. As shown in
In certain implementations, the disclosed system can check if the user is or was the owner of the article. The system can receive one or more contract and/or wallet address(es) of the user and can check if the contract and/or wallet address(es) and the token ID are linked in the NFT transactions.
Referring to
In certain implementations, the disclosed system can check authenticity using combined processes as described in
In certain implementations, the disclosed system can be advantageous by allowing any crypto wallet to be used for minting the NFTs. The NFT information to be incorporated into the physical tag can be obtained by the system, the information can be the minting contract and/or wallet address(es), token ID, and UUID. The UUID can be randomly generated by the system or by any other source. The UUID, in encrypted form, can be present in the physical tag and the copy of UUID and the respective private key can be received by the system and incorporated into the unlockable section of the NFT.
In certain implementations, the NFT can have unlockable content that can be accessed only by the current owner of the NFT. In the unlockable content, the UUID and encryption keys can be stored. The encryption key can be for the encrypted UUID of the physical tag.
In another implementation, the NFT can be minted by creating a unique contract, in which case, the NFTs may be minted into a wallet owned by the creator, or they may be minted directly into a recipient's wallet. In this case, the contract address from which the NFTs originate is tied to creator, but the initial wallet address may or may not be tied to the creator.
Level 1 authentication can at least ensure that the user has physical access to the object, the user may or may not be the owner. Having the article, the user can have access to certain services provided by the system, wherein such services can be accessed through the first screen. An exemplary embodiment of the first screen is shown in
In certain implementations, the owners of articles as verified by the system using the level 2 authentication can determine the features, services, and limitations in the first screen. Authenticated as the owner of an article, the owners can include the ability to add options, information, or functionality accessible to users who only have physical access, and the owner could also set conditions on how, when, or where a user must be to access options, information, or functionality. For example, a certain button on the menu may only be available during specific times or might disappear from the menu if the user left the area where the physical object resides. Another example might be to allow certain options, information, or functionality to only be presented to specific people (identified by wallet addresses they would have to log in with, or perhaps they might need to own a different token from the same source).
It is an advantage to use a contract and/or wallet address(es) for verification as it can inform about the origin of the article i.e., the creator who created the NFT. The minting contract and/or wallet address(es) of each Digital NFT can be from a contract and/or wallet address(es) unique to the true source of the physical object, whether it's an artist, entertainer, celebrity, athlete, organization, etc., it better provides for the authenticity of the source of the physical article/object.
A unique set of keys is generated for every paired Digital NFT and Physical tag, this helps protect each item significantly better since the NFT encryption would need to be broken for every NFT individually, it allows for future NFT pairs to use stronger encryption as needed. The PGP key that would normally be public is kept private and used only by the owner to verify that the Physical tag and Digital NFTs are a matched pair.
The disclosed system and method allow a physical article or object to be represented by a digital NFT using a physical tag. The disclosed system and method allow authenticating the origin and current ownership of the article based on the NFT. For example, VR/Metaverse spaces allow a digital NFT to be displayed. The incorporation of the token id and contract and/or wallet address(es) in the physical tag in unencrypted form allows sharing of the public identity of the physical article through the associated NFT. This makes possible one level of pairing and authentication for those with physical access but who isn't the owner, while providing a deeper level of pairing for the owner of the object, as designated by ownership of the Digital NFT, whose owner alone can unlock the verification key and UUID in the Digital NFT, and then verify the encrypted UUID.
While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above-described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
