  • Secure format-preserving encryption of data fields
    Patent number: 9858436
    Abstract: In one embodiment, a computer-implemented method includes extracting first key derivation data from a first row of data to be stored in a database, where the database includes two or more rows of data. A first encryption subkey is generated, by a computer processor, by combining the first key derivation data with a static key. One or more sensitive fields in each row of the two or more rows of the database are encrypted using a unique corresponding encryption subkey for the row, and the first encryption subkey is unique to the first row among the two or more rows of the database. The one or more sensitive fields in the first row of data are encrypted with format-preserving encryption using the first encryption subkey. The first row of data, including the encrypted one or more sensitive fields, are stored in the database.
