Abstract

SecureMed-ID improves the memorability of identifiers used by electronic medical record systems. Making identifiers that are easier to remember should improve the privacy of the medical record system by preventing leaks due to human error. SecureMed-ID can easily transform the commonly-used Globally Unique Identifier (GUID) system into a human-friendly two-word alias. This system hides much of the complexity of information identification and provides short-cuts for effective human-mediated data sharing protocols. These include written reports, telephone conversations, or email and text messages. SecureMed-ID only requires the user to remember two common English words for any type of data rather than less memorable alphanumeric IDs. The SecureMed-ID system has been tuned to minimize the number of keystrokes required to input a unique identifier since future searches will come from mobile devices with smaller keyboards. Finally, this identification system reduces the need to input personally identifying information into a mobile device electronic medical record interface. A demonstration system containing 34,000 records, ArrayWiki, is available on the web at http://arraywiki.bme.gatech.edu. SecureMed-ID (1) provides doctors with a means to retrieve specific de-identified medical data without providing identifying information about the patient associated with the data, (2) represents user-focused design by using dictionaries consisting of familiar words with high typing efficiencies; and (3) provides a shortcut to data that seamlessly works with existing ID systems, inside and outside the medical community.
