United States Patent 7266699 was issued to AppSecInc. From the patent
"The invention provides a transparent encryption infrastructure which
allows the user to point-and-click on columns and tables to encrypt
data. The creation of triggers and views are also easily implemented,
to encrypt and decrypt data, to manage the encryption keys and to grant
and revoke access to a column. Public and private key pairs are hashed
and encrypted with a valid password. The process or encryption starts
by creating a randomly generated symmetrical key, encrypting the
symmetrical key with the private key for each user authorized to
decrypt the data, and storing the encrypted symmetrical key, along with
the user's name and the column name, in the database."
from Darkreading
"The newly patented Application Security, Inc. invention gives database
administrators (DBA’s) the ability apply modern cryptography to the
database systems they administer. It provides a transparent encryption
infrastructure, which – via a graphical user interface – allows DBAs to
select the columns within the database they’d like to encrypt and
choose the algorithm they’d like to apply. DBAs can select encryption
strength, leveraging a graphical console that allows the creation of
working code with simple point-and-click functionality. Database
triggers and views are automatically created and implemented with this
approach to efficiently encrypt and decrypt data with minimal impact on
database performance; to securely manage multiple encryption keys; and
to grant and revoke cleartext access to a data column."
