1. A method comprising:

  • determining biometric data from a user equipment associated with a user;

    causing decomposition of the biometric data into one or more closure primitives that represent computation closures of one or more processes of the user equipment;

    selectively authenticating the user based on the decomposition of the biometric data, wherein the authenticating comprises verifying semantic information;

    retrieving media to provide to the user equipment as part of a challenge procedure, wherein the media includes textual information, an image, or a combination thereof;

    determining to transmit the media to the user equipment to obtain a response to the challenge procedure, wherein the response includes the biometric data;

    wherein the biometric data includes a voiceprint, an utterance, and the textual information includes one or more words;

    verifying the voiceprint as part of the challenge procedure;

    verifying the textual information based on the voiceprint as part of the challenge procedure; and

    verifying the semantic information presented in the utterance as part of the challenge procedure.
