Consented identity as a service

A server includes an identity certainty model, which has permutation ensembled weights. The server receives a plurality of data access consent receipts from an external consent repository. Based on the data access consent receipts, the server retrieves a plurality of data types from one or more data providers. The server executes the identity certainty model on the data types. The server performs an ID resolution operation on the data types. Using data outputs produced by the ID resolution operation, the server calculates metrics from the ID resolution operation. A weighting of the data outputs produced by the metrics calculations is performed using the permutation ensembled weights. An identity protection score and a risk score are determined based on the weighted data outputs. An optimization operation is performed on the identity protection score and the risk score to determine an identity certainty score.
