Abstract

An apparatus for dynamic user authentication comprises a processor associated with a server. The processor is configured to receive session data associated with a first user, wherein the session data comprises user parameters for a session and to receive an interaction request to authorize an interaction of a first avatar associated with the first user in a virtual environment. The processor is further configured to compare the user parameters of the session data to user parameters of a stored user profile and to authorize the interaction in response to comparing the session data to the stored user profile if a confidence threshold is satisfied. The processor is further configured to train the machine learning algorithm with the received session data to update the user profile, wherein updating the user profile improves information security by authenticating that the first user is authorized to interact via the first avatar.

Dependent claims

An apparatus for dynamic user authentication, comprising:

a memory operable to:
store a user profile associated with a first user in a file, wherein the user profile is created through a machine learning algorithm and comprises user parameters associated with the first user, wherein the user parameters are determined through an enrollment procedure comprising receiving training data to establish the user profile;
and
a processor, operably coupled to the memory, configured to:
receive session data associated with the first user, wherein the session data comprises user parameters for a session;
receive an interaction request to authorize an interaction of a first avatar associated with the first user in a virtual environment, wherein the interaction is between the first avatar and a second avatar or a virtual object;
compare the user parameters of the session data to the user parameters of the stored user profile to satisfy a minimum percentage difference;
authorize the interaction in response to comparing the session data to the stored user profile if a confidence threshold is satisfied, wherein the confidence threshold is satisfied by a minimum number of user parameters of the session data satisfying the minimum percentage difference;
and
train the machine learning algorithm with the received session data to update the user profile.

A non-transitory computer-readable medium comprising instructions that are configured, when executed by a processor, to:

receive session data associated with a first user, wherein the session data comprises user parameters for a session;
receive an interaction request to authorize an interaction of a first avatar associated with the first user in a virtual environment, wherein the interaction is between the first avatar and a second avatar or a virtual object;
compare the user parameters of the session data to user parameters of a stored user profile to satisfy a minimum percentage difference, wherein the stored user profile is created through a machine learning algorithm and comprises user parameters associated with the first user, wherein the user parameters of the stored user profile are determined through an enrollment procedure comprising receiving training data to establish the user profile;
authorize the interaction in response to comparing the session data to the stored user profile if a confidence threshold is satisfied, wherein the confidence threshold is satisfied by a minimum number of user parameters of the session data satisfying the minimum percentage difference;
and
train the machine learning algorithm with the received session data to update the user profile.
