Systems and methods for secure tokenized credentials

A method for authentication using secure tokens, the method comprising:

• receiving one or more data sets representing one or more biometric verification credentials;
• extracting, from the one or more data sets, a data subset representing a constrained set of features identifying an individual;
• transforming the constrained set of features in combination with one or more cryptographic keys to generate a digitally signed token;
• and
• storing the digitally signed token in a data storage resident on the mobile computing device;
• wherein the digitally signed token, when processed by a third party computing device, indicates that one or more characteristics of the individual are verified by one or more parties associated with each cryptographic key of the one or more cryptographic keys;
• wherein the one or more data sets include one or more image sets storing a facial representation and a model data architecture trained based on speech motions of the individual, the transformation includes combining the facial representation, the model data architecture, and the one or more cryptographic keys into the digitally signed token;
• wherein the third party computing device is configured for:
• processing the digitally signed token upon receiving a challenge response data set representative of one or more response images representing an unverified individual speaking one or more response passphrases;
• and
• validating the challenge response data set against the facial representation and the model data architecture to establish that the one or more response passphrases satisfies an output of the model data architecture at least at a pre-defined confidence threshold value in respect of determining that the unverified individual is the individual associated with the digitally signed token.

A computer system for verification of secure tokens, the computer system comprising computer memory, and a processor configured to:

• receive, from a portable computing device, a digitally signed token including a set of transformed data based at least on a constrained set of features in combination with one or more cryptographic keys, the transformed data including a model data architecture trained based on speech motions of an individual in relation to one or more passphrases;
• receive a challenge response data set representative of one or more response images representing an unverified individual speaking at least one passphrase of the one or more response passphrases;
• validate the challenge response data set against the model data architecture to establish that the one or more response passphrases satisfies an output of the model data architecture at least at a pre-defined confidence threshold value in respect of determining that the unverified individual is the individual associated with the digitally signed token;
• validate that the digitally signed token includes at least one cryptographic signature from an approved issuer party computing device;
• and
• upon successful validation of the challenge response data set and the at least one cryptographic signature, provision access to a controlled resource.
