Abstract
Methods and system for risk determination and risk categorization using encrypted data are provided. The risk determination can involve determining an inner product operation between a generalized weight table and an encrypted incidence vector, summing the result of the inner product operation and/or decrypting the results. Method and systems for encrypting data for use in homomorphic risk determination are also provided.
