We assessed a data security system using biometric fingerprint techniques and smartcards to control access to a teleradiology system. Clinical cases were initially discussed between the referring physician and radiologist in Tyrol using a video-phone. Subsequent correspondence, including the transmission of images between the referring physician and the radiologist, was carried out by e-mail using the security system to prevent unauthorized access to patient information. Seventy-eight teleradiology sessions were conducted using this data security system. Speed and stability of data exchange were unaffected by the additional security feature. The average log-on time to the system was 7.8 s. The average training time on how to use the system was 15 min. The radiologist was able to issue a final patient report using the system within 1.5 of the initial contact. The data security feature was user-friendly and did not hinder the normal teleradiology consultation.
