Security is handled in CWA through 32-bit encryption. All sensitive information is encrypted (scrambled) and is stored only as encrypted text. The original information is not stored anywhere in the CWA database, and the only way it can be decrypted is by means of a key that is stored in a separate, secured system.
CWA has access to only the last four digits of your social security and driver's license number, which are used only for security verification.
