1. A method for a computing system, comprising:
capturing, with a biometric capture portion in a biometric capture device, a plurality of biometric data associated with a user;
determining, with a first processing portion of the biometric capture device, a biometric cryptographic key in response to the plurality of biometric data;
receiving, with a user input portion of a first smart device, a first set of user input data under direction of the user;
selecting, with a second processing portion of the first smart device, a first forcing function and a first set of input parameters for the first forcing function based at least in part on receiving the first set of user input data, wherein the first forcing function, the first set of input parameters, or both, are selected from a plurality of forcing functions or a plurality of input parameters, respectively, based at least in part on the first set of user input data;
combining, using the first forcing function, the first set of user input data and the biometric cryptographic key based at least in part on selecting the first forcing function and the first set of input parameters for the first forcing function;
outputting, from the first forcing function, a first output cryptographic key in response to combining the biometric cryptographic key and the first set of user input data using the first forcing function, wherein the first output cryptographic key is based least in part on the biometric cryptographic key, the first set of user input data, the first forcing function, and the first set of input parameters, without reference to any encrypted forms of the first output cryptographic key; and
using, with the second processing portion of the first smart device, the first output cryptographic key to access a first digital asset.
