A telemonitoring central server 12 supports secure data exchange between a number of users, such as a patient, family and friends, medical personnel, suppliers, and the like. A user authenticator 20 authenticates and authorizes a user to the system. Access control is driven by a number of static or dynamic access profiles that are assigned to each user. These profiles dictate the data to which the user is allowed access, the computations available to the user, and the manner in which data is displayed to the user. The presentation style is based on access role, user, age, background, result of previous interactions, information content, authentication level, and the like. Third-party services such as advertisements and discounts for “get well soon” items can also be provided to the user.
