System And Method For Providing Owner Verification Of Avatar Information To Protect Avatar Information In The Metaverse Platform From False Avatar Information}

The present invention relates to a system and method for providing owner verification of avatar information for protecting avatar information in a metaverse platform from false avatar information, and a user's biometric information, activity information, and medical information through a VR device. , and based on this, an avatar can be created in virtual reality, information about the avatar is registered in the NFT, and information about the avatar is provided to the metaverse platform to provide owner information and avatar registered in the NFT. A system and method for verifying owner information received from a metaverse platform based on hash information and verifying forgery and falsification of information about the avatar, and a system and method for providing owner verification for avatar information.

Metaverse technology is a four-dimensional virtual space-time that connects economic, social, cultural, and political activities through an avatar, a virtual self. The metaverse technology is a concept including virtual reality, augmented reality, mirror world, and lifelogging. These metaverse technologies are being used in conjunction with various technological fields such as games, education, shopping, medical care and tourism. Therefore, avatar creation is essential.

Accordingly, the utilization of the avatar reflecting the user's information is expected to be high. For example, when the user's medical data is reflected in the avatar, the avatar can be used to perform medical services and telemedicine in the metaverse, and can be used for insurance review. However, when the owner of such medical data is changed and other people's medical data is reflected or forged, there may be a problem of reliability of the avatar, so a system is needed to solve this problem. .

On the other hand, NFT stands for Non-Fungible Token and refers to non-fungible tokens. NFT proves the digital original and gives it a value of scarcity. An NFT is a digital file representing a specific asset, and each NFT has its own uniqueness, so it cannot be replaced with each other and exists on the blockchain. Since NFTs cannot be deleted or forged once created, they can authenticate the original and prove ownership of assets registered as NFTs. Due to the nature of the digital domain, unlimited copying and distribution of digital assets is possible, but by using NFT, scarcity value can be given to digital assets. In addition, it is possible to verify the forgery of data by utilizing the immutable characteristics of the NFT.

Virtual reality, which is used to create an avatar, is a technology that allows a user to experience a virtual space implemented on a computer by wearing an input/output device such as a head mounted display (HMD) device. It is a technology that allows you to experience a specific situation without temporal or spatial constraints in the implemented virtual space. It was predicted that such virtual reality technology would be difficult to popularize in the near future due to the lack of expensive equipment and virtual reality content. It is also being re-examined.

As a method for building a health care environment for user's health promotion, Korean Patent Application Laid-Open No. 10-2020-0022776 creates a 4D avatar for the user and induces the user to perform a specific operation without requiring the user to visit the hospital. A method for performing rehabilitation exercises has been suggested. However, the prior art simply estimates the user's movement information based on the user's joint information and generates a user avatar that can experience virtual reality. There is no disclosure on a method of generating and improving user immersion. In addition, the conventional techniques as described above did not disclose a method of verifying forgery or falsification of the information on the avatar when the information on the created avatar is provided to the metaverse platform.

Therefore, an avatar similar to the user's appearance and body characteristics is created, information about the avatar is provided to the metaverse platform, and the owner and forgery of the information on the avatar are verified to protect the user's information reflected in the avatar. The need to develop a system that can do this is emerging.
