Abstract:
1. A method for retrieving encrypted biometric data, comprising: obtaining a biometric measurement; applying a predetermined noise to the biometric measurement to get a scrambled biometric, the noise being a cancelable technology component determined using a hash function and different from background noise and encryption key; encrypting the scrambled biometric with a non-invertible encryption function to get a scrambled encrypted biometric; accessing a data storage having a plurality of encrypted biometric entries, the encrypted biometric entries being encrypted with the non-invertible encryption function; subtracting an encrypted biometric entry of the plurality of encrypted biometric entries from the scrambled encrypted biometric to get a calculated noise; comparing the calculated noise with the predetermined noise to determine whether a match exists using a tolerance for the comparison between the calculated noise and the predetermined noise to determine whether the match exists; based on a determination that the match exists, receiving information associated with the encrypted biometric entry; and analyzing the information associated with the encrypted biometric entry, wherein analyzing is indicative of a medical condition indicated by the biometric measurement.
