1. A system comprising:
a memory, storing first computer-executable instructions; and
a hardware processor to execute the first computer-executable instructions to:
determine a first set of anchor data comprising a plurality of biometric input data;
determine a plurality of anchor embeddings using the first set of anchor data as input to a first trained embedding network module, wherein the plurality of anchor embeddings are associated with a first embedding space;
determine input image data of a hand, wherein the input image data comprises surface and subcutaneous features of the hand;
determine first embedding data using the input image data as input to the first trained embedding network module, wherein the first embedding data is associated with the first embedding space;
determine, relative to the first embedding data, a first set of top k closest anchor embeddings wherein k is a positive nonzero integer;
determine a first cryptographic key based on the first set of top k closest anchor embeddings;
encrypt the input image data using the first cryptographic key to determine encrypted input image data; and
store the encrypted input image data.
