SYSTEMS AND METHODS FOR PROVIDING A TRACKABLE DIGITAL ASSET AND ITS USE THEREOF

Description

TECHNICAL FIELD

This invention relates to digital assets. More precisely, one or more embodiments of the invention relate to a computer-implemented method and a system for providing a trackable digital asset.

BACKGROUND OF THE ART

The market value of digital assets is increasing every year as they become more and more popular. Generally, a digital asset is a digital file which comes with rights of use and has an associated value. It will be appreciated that digital assets can be traded, for instance, in blockchains such as Ethereum™, FLOW™, Tezos™, Solana™, and the like, which advantageously allow to track record of ownership of the digital asset. Since ownership of a digital asset is limited to typically a single owner, a certain value can be associated to the digital asset which a buyer would have to trade for in order to acquire the ownership of the digital asset.

To ensure ownership of a digital asset, the latter is usually encrypted using cryptographic methods and contains information about the owner. Yet, such transactions usually limit the digital asset to a pure commodity, and the authenticity of the digital asset is not considered, due to a lack of traceability. For instance, one could simply copy a publicly available digital asset, mint the digital asset in a blockchain and sell the digital asset to a buyer without giving credit to the original creator and the previous owners of the digital asset. While being operational, such systems omit the authenticity aspect of the transaction of a digital asset, which is a serious drawback.

There is therefore a need for at least one of a method and a system that will overcome at least one of the above-identified drawbacks.

It will be appreciated that one or more embodiments of the methods and the systems disclosed are of great advantages for various purposes.

A first advantage of one or more embodiments of the methods and the systems disclosed herein is that the present technology enables preserving the authenticity of a digital asset when trading thereof, thus enabling the trading of digital assets similarly to the trading of physical assets, thereby adding value to the digital assets. For instance, a person purchasing a digital asset which is known to be authentic will tend to give a greater value to the digital asset than if the authenticity cannot be established or confirmed. Further, the fact that the digital asset is trackable encourages buyers and artists to join a system using trackable digital assets. Furthermore, knowing that a digital asset is authentic and that the digital asset has been indeed originally created by its creator prevent the trade of fraudulent digital assets.

A second advantage of one or more embodiments of the methods and the systems disclosed herein is that encrypting the trackable digital asset and/or the password to encrypt the trackable digital asset enables to secure a digital transfer while minimizing a risk of theft. In addition, because of data embedded in the digital asset and at least one one-way cryptographic encryption of at least one portion of the trackable digital asset, if at least one of the digital asset and the trackable digital asset is leaked by a buyer and/or a seller, malicious individuals will be unable to claim ownership of the at least one of the digital asset and the trackable digital asset.

A third advantage of one or more embodiments of the methods and the systems disclosed herein is that it is possible to track digital assets with the data embedded therein, thus possibly enabling imposing limitations on the use and trade of trackable digital assets, such as, and without being limited to, preventing the trackable digital assets to be stored in determined databases or prohibiting the trade of non-trackable digital assets and/or trackable digital assets in determined blockchains or marketplaces.

A fourth advantage of one or more embodiments of the methods and the systems disclosed herein is that it is possible to decrypt an encrypted trackable digital asset without a user having to remember a password that encrypts the trackable digital asset, since an identifier encrypting the password may be automatically used to recover the password and therefore enables to decrypt the encrypted trackable digital asset without having the user to provide the password, in accordance with one or more embodiment.

The skilled addressee will appreciate that the technology presented herein is not bound to any particular brand and/or label, whether already widely known or not. The skilled addressee will appreciate that a technology part of a system comprising and/or enabled by digital asset(s) is often labelled and/or branded to relate to transparency, attractiveness and/or understandability, which may help in a process of establishing trust, determining at least one incentive and/or engaging with the branded and/or the labelled technology in relation to a consumer. The technology presented herein may be referred to as NFTProtect (PA), ProtectArt (PA), DataProtect (DP), and/or any suitable brand and/or label per se. The skilled addressee will appreciate that the above-mentioned brands and/or labels may be associated with one or more other technology not related to the one presented herein. At least one of the above-mentioned brands and/or labels may still be considered as relevant for the branding and/or the labelling of the current technology.

In one or more embodiments, the processing device 102 is one-way encrypting the trackable digital asset at least once. In one or more other embodiments, the processing device 102 is providing the trackable digital asset, for example via the communication network 104, to the server 105 and the latter is performing the at least one one-way cryptographic encryption of at least one portion of the trackable digital asset 106. In yet another embodiment, an indication of the at least one one-way cryptographic encryption of at least one portion of the trackable digital asset 106 is provided instead of the at least one one-way cryptographic encryption of at least one portion of the trackable digital asset 106. In yet another embodiment, the server 105 is providing a set of computer instructions via the communication network 104 to the processing device 102, the set of computer instructions allowing to one-way encrypt the trackable digital asset at least once on the processing device 102. In one or more embodiments, the trackable digital asset is directly provided to the server 105 without being provided to the processing device 102 in the first place. The skilled addressee will thus appreciate that the obtaining of the at least one one-way cryptographic encryption of at least one portion of the trackable digital asset 106 is not limited to the embodiments disclosed herein and that various alternative embodiments may be provided for providing the at least one one-way cryptographic encryption of at least one portion of the trackable digital asset 106.
