All information collected in the online forms is transmitted via an ssl encrypted connection and stored in a secure database (the secure socket is embedded within the page frame). In addition, sensitive fields such as ss# are encoded in a secure hash within the database. 

 This is the same level of security used by most banks and government agencies for secure data transmission.
