“Encrypted” means transformation of data through the use of an algorithmic process into a form in which there is a low probability of assigning meaning without use of a confidential process or key, or securing information by another method that renders the data elements unreadable or unusable.

“Redact” means to alter or truncate data so that no more than four sequential digits of a driver license number, state personal identification card number, or account number, or no more than five sequential digits of a social security number, are accessible as part of personal information.
