Privacy by design

Definition
Privacy by design means that businesses should build privacy protections into their everyday business practices.

Overview
Such protections include providing reasonable security for consumer data, collecting only the data needed for a specific business purpose, retaining data only as long as necessary to fulfill that purpose, safely disposing of data no longer being used, and implementing reasonable procedures to promote data accuracy.

Companies also should implement and enforce procedurally sound privacy practices throughout their organizations, including, for instance, assigning personnel to oversee privacy issues, training employees on privacy issues, and conducting privacy reviews when developing new products and services.
