1. A system comprising:
a processor; and
a non-transitory computer-readable memory storing instructions that, when executed by the processor, cause the processor to:
receive an image of a biometric identifier of a user;
receive a set of generic biometric images that does not include the image of the biometric identifier of the user;
train a neural network on the set of generic biometric images to yield a trained neural network;
convert the image into a key by:
transforming the image into an image data matrix;
combining the image data matrix with a randomized initialization matrix to create the key; and
converting the image into the key by inputting the image into the trained neural network;
use the key to encrypt data to create encrypted data; and
discard the image of the biometric identifier and the image data matrix.
