Abstract

Security measures are provided for resource exchange events occurring within a virtual environment, such as metaverse or the like. Intelligent resource exchange event authentication is realized by leveraging Artificial Intelligence (AI) and, more specifically, Machine Learning (ML) techniques to identify user behavioral patterns associated with previous resource exchange events conducted within the virtual environment and, in some instances, non-virtual environment. Current resource exchange event characteristics are compared to the user behavior patterns to ensure that the resource exchange event is authentic/legitimate. Additionally, intelligent user authentication occurs by leveraging the use of a Non-Fungible Token (NFT) that is presented by the user at the onset of the resource exchange event and is verified within a distributed trust computing network.

Dependent claims

A system for authenticating a user and a virtual resource exchange event, the system comprising:

a distributed trust computing network comprising a plurality of decentralized nodes, each decentralized node having a first memory and one or more first processing devices in communication with the first memory, wherein the first memory of the decentralized nodes is configured to store one or more distributed ledgers, each distributed ledger comprising a plurality of data blocks, wherein in response to a virtual object associated with the user initiating the virtual resource exchange event, a Non-Fungible Token (NFT) associated with the user is received by the distributed trust computing network and a plurality of the decentralized nodes are configured to validate the NFT, and, in response to validating the NFT, store a data block associated with virtual resource exchange event within one of the one or more distributed ledgers, wherein validating the NFT serves to authenticate the user;
and
a first computing platform including a second memory and one or more second processing devices in communication with the second memory, wherein the second memory stores a virtual resource exchange event authorizer tool that is executable by at least one of the one or more second processing devices and is configured to:
implement one or more Machine Learning (ML) algorithms to:
learn one or more first user behavior patterns, each first user behavior pattern indicating a pattern of behavior of the user in conducting, at least, prior virtual resource exchange events, and
in response to receiving data associated with the virtual resource exchange event being initiated by the virtual object, apply the one or more first user behavior patterns to the data associated with the virtual resource exchange event to determine whether the virtual resource exchange event is authentic, and
in response to (i) the distributed trust computing network validating the NFT, and (ii) determining that the virtual resource exchange event is authentic, authorize processing of the virtual resource exchange event.

A computer-implemented method for authenticating a user and a virtual resource exchange event, the computer-implemented method is executable by one or more computing processor devices, the method comprising:

in response to a virtual object associated with a user initiating the virtual resource exchange event, receiving, at a distributed trust network, a Non-Fungible Token (NFT) associated with the user;
validating, by a plurality of decentralized nodes of the distributed trust computing network, the NFT, wherein validating the NFT serves to authenticate the user;
in response to validating the NFT, storing a data block associated with virtual resource exchange event within a distributed ledger of the distributed trust computing network;
implementing one or more Machine Learning (ML) algorithms to learn one or more first user behavior patterns, each first user behavior pattern indicating a pattern of behavior of the user in conducting, at least, prior virtual resource exchange events;
in response to receiving data associated with the virtual resource exchange event being initiated by the virtual object, implementing ML techniques to apply the one or more first user behavior patterns to the data associated with the virtual resource exchange event to determine whether the virtual resource exchange event is authentic;
and
in response to (i) the distributed trust computing network validating the NFT, and (ii) determining that the virtual resource exchange event is authentic, authorizing processing of the virtual resource exchange event.

A computer program product comprising:

a non-transitory computer-readable medium comprising:
a first set of codes for causing a computer to, in response to a virtual object associated with a user initiating the virtual resource exchange event, receive, at a distributed trust network, a Non-Fungible Token (NFT) associated with the user;
a second set of codes for causing a computer to validate, by a plurality of decentralized nodes of the distributed trust computing network, the NFT, wherein validating the NFT serves to authenticate the user;
a third set of codes for causing a computer to, in response to validating the NFT, store a data block associated with virtual resource exchange event within a distributed ledger of the distributed trust computing network;
a fourth set of codes for causing a computer to implement one or more Machine Learning (ML) algorithms to learn one or more first user behavior patterns, each first user behavior pattern indicating a pattern of behavior of the user in conducting, at least, prior virtual resource exchange events;
a fifth set of codes for causing a computer to, in response to receiving data associated with the virtual resource exchange event being initiated by the virtual object, implement ML techniques to apply the one or more first user behavior patterns to the data associated with the virtual resource exchange event to determine whether the virtual resource exchange event is authentic;
and
a sixth set of codes for causing a computer to, in response to (i) the distributed trust computing network validating the NFT, and (ii) determining that the virtual resource exchange event is authentic, authorizing processing of the virtual resource exchange event.
