A secure method and apparatus for data exchange that allows a client's or
patient's financial data, medical records, and other information to be
stored on a card-shaped compact disk, with multiple levels of encryption
to preserve privacy. The trusted record disc can be read on any computer
with a network or internet connection, but access to the information on
the disc is restricted according to a password protected hierarchical
encryption policy. In order to obtain access to the restricted
information, an individual user needs to enter a unique password that is
sent to a central server. The server confirms the password and returns an
electronic key to the user's computer. The electronic key unlocks the
encryption and allow the user to view only the information that is
permitted (under federal patient, financial privacy or other laws). Thus,
in the medical setting, physicians can review the patient's entire
medical record and make changes to it. Nurses, pharmacists, and billing
clerks have differing predetermined levels of access.
