Device-agnostic access control techniques

A method comprising:

• determining, by a processing device, a historical entity vector for a first entity having performed an authentication attempt associated with authentication data, the historical entity vector comprising a plurality of features each comprising a plurality of sub-features, the historical entity vector determined by:
• generating, by the processing device, synthetic data based on a plurality of historical authentication attempts associated with one or more second entities;
• generating, by the processing device and based on the synthetic data, weights corresponding to the plurality of sub-features of the historical entity vector;
• and
• determining, by the processing device, a plurality of probabilities of the plurality of sub-features using the weights of the plurality of sub-features, each probability of the plurality of probabilities indicating a likelihood that a corresponding sub-feature is involved in the authentication attempt;
• and
• generating, by the processing device, a responsive message by comparing the historical entity vector and the authentication data, the responsive message for use in controlling access to an interactive computing environment.

A non-transitory computer-readable medium comprising instructions that are executable by a processing device for causing the processing device to perform operations comprising:

• determining a historical entity vector for a first entity having performed an authentication attempt associated with authentication data, the historical entity vector comprising a plurality of features each comprising a plurality of sub-features, the historical entity vector determined by:
• generating synthetic data based on a plurality of historical authentication attempts associated with one or more second entities;
• generating, based on the synthetic data, weights corresponding to the plurality of sub-features of the historical entity vector;
• and
• determining a plurality of probabilities of the plurality of sub-features using the weights of the plurality of sub-features, each probability of the plurality of probabilities indicating a likelihood that a corresponding sub-feature is involved in the authentication attempt;
• and
• generating a responsive message by comparing the historical entity vector and the authentication data, the responsive message for use in controlling access to an interactive computing environment.
