Abstract

Meeting participation and presentation information about an individual or project is collected from public and private systems into an electronic record. The data is represented as NFTs and stored on a block chain and used to reward participants based on their contributions and actions relating to the meeting or due to the presentation. All of this is done securely and in compliance with privacy protocols.

Claims (19)

1 . A computer-implemented method in a system, on a data communication network, for providing immutable video chat history transactions within a non-fungible cryptographic token (NFT) based video chat session certificate, the method comprising:

creating a user private key/wallet address pair associated with a specific user to interact with the system, wherein the user private key/wallet address pair is associated with a specific blockchain;

creating an entity private key/wallet address pair associated with a specific entity to interact with a smart contract and store at least a portion of a user data associated with the specific user on the blockchain;

creating the smart contract for user data associated with a relationship between a specific user and a specific entity in a video chat session history database;

generating a new NFT in a series on the specific blockchain according to new video chat session data using the smart contract and authorized by the private key/wallet key pair of the specific user or the specific entity to activate the video chat session history; and

sending the NFT to the user private key/wallet address pair.

2 . A non-transitory computer-readable medium in a video chat system, on a data communication network, storing code that when executed, performs a method for capturing video chat session history using a non-fungible cryptographic token (NFT) based video chat session certificate, the method comprising:

creating a user private key/wallet address pair associated with a specific user to interact with the system, wherein the user private key/wallet address pair is associated with a specific blockchain;

creating an entity private key/wallet address pair associated with a specific entity to interact with a smart contract and store at least a portion of a user data associated with the specific user on the blockchain;

creating the smart contract for user data associated with a relationship between a specific user and a specific entity in a video chat session history database; and

generating a new NFT in a series on the specific blockchain according to new video chat session data using the smart contract and authorized by the private key/wallet key pair of the specific user or the specific entity to activate the video chat session history.

3 . A video chat system, on a data communication network, for capturing video chat session history using a non-fungible cryptographic token (NFT) based on a chat session certificate, the video chat system comprising:

a processor;

a network interface communicatively coupled to the processor and to a data communication network; and

a memory, communicatively coupled to the processor and storing instructions that when executed by the processor:

create a user private key/wallet address pair associated with a specific user to interact with the system, wherein the user private key/wallet address pair is associated with a specific blockchain;

create an entity private key/wallet address pair associated with a specific entity to interact with a smart contract and store at least a portion of the video chat data associated with a specific renter on the blockchain;

create the smart contract for renter data associated with a relationship between the specific user and the specific entity in a chat video session history database; and

generate a new NFT in a series on the specific blockchain according to new video chat session data using the smart contract and authorized by the private key/wallet key pair of the specific user or the specific entity to activate the video chat session history.
