Abstract
Methods and systems are provided for changing an encryption key for biometric templates in a database without changing the content within the database. A first biometric template is encrypted with a first encryption key to create a first encrypted first biometric template. A transformation is applied to the first encrypted first biometric template to create a second encrypted first biometric template. A second encryption key is generated based on the first encryption key and the transformation permitting the use of the second encryption key to compare presented biometrics encrypted with the second encryption key with templates stored in the database.
