Most of the recent discussions about the protection of personal information and in particular health information have focussed on the impact of developments in informa- tion technology and the increasing use of computerized record systems. “The health care industry is in the midst of an era of unprecedented computerization of medical records

and data.”66Computerizing records is part of many health care reform proposals, since
it would not only increase efficiency but also significantly cut costs.67However, the
general public is apparently nervous about the potential effects of these changes: in recent polls 85 per cent of people said that protecting confidentiality of medical records was very important to them, and 90 per cent believed that computers make it easier for someone to improperly obtain personal information.68While there is some disagree-
ment about the exact nature and extent of the impact of technology on the protection of privacy, there is no doubt that “pervasive use of computers has enhanced society’s ability to collect, store, retrieve, process, and disseminate data on individuals, quite often with- out the individual’s knowledge and consent.”69
For instance, the ease of recording and storing information in computer databases may mean that information will be collected and retained that might not have been otherwise.70The centralized storage of large amounts of information also increases the
likelihood and severity of breaches of privacy. Traditionally, records have been kept in manual form in a number of different (and usually secure) locations, making it difficult to obtain information and especially to obtain and combine a wide range of data from vari- ous sources.71Unless special protections are built into the system, access to a database can
provide an authorized or unauthorized user with an unprecedented amount of informa- tion. Even when different sets of data are held in different systems, it is often possible to “link” or “match” the data for a particular individual using some identifier. This practice, known as computer matching, presents a serious threat to personal privacy since it allows a user to compile a detailed dossier or profile on an individual by linking data from many different sources,72and thereby acquire extensive knowledge about that person,73without
the individual’s knowledge or consent. Matching may also detach information from its context and lead to the proliferation of false or misleading information.74
As a result, the means by which health information is identified in a computer system has become extremely important. In health care, the use of unique identifiers (a name, number or other unique marker for each individual)75would allow a compre-
hensive record for each patient to be compiled from information scattered geographical- ly and over the years. These “patient-based longitudinal records,” which would contain “all data relevant to the health of an individual … collected over a lifetime,”76would
carry obvious benefits for quality of care and administrative efficiency. However, the additional threat to privacy means that limits on the use of unique identifiers may be appropriate.77Of special concern is the use of an identifier that would allow links to be
made between health records and other forms of personal data. For example, privacy advocates in the United States strongly resisted the proposed use of the social security number (SSN) as an identification number for the reformed health care system.78
Because of the widespread use of the SSN by both government and private entities, the SSN may be used to access and link information about many aspects of a person’s life.79
Those concerned about privacy are alarmed at the prospect of this pool of information

including intimate details about a person’s health. The use of a number specific to the health care system would help to alleviate these concerns.80
The choice of an identifier is one issue to be considered with respect to health care cards. Developing technology has also added other issues, however. Various types of cards have been used for identification and insurance purposes in the health care system for many years. Typically, these cards carried basic information that was printed or embossed on the card.81Several types of “advanced card technologies” (“smart cards”)
are now available, including magnetic strip, integrated circuit and optical storage cards.82These cards can not only store much larger amounts of information (including
images such as x-rays, for optical storage cards), but can also process information and be used to access central databases.83The cards could be used for identification, insur-
ance, communication between care providers and as a portable, comprehensive patient records, which could be valuable for emergency and outreach care.84Pilot projects have
already begun testing the use of such cards in many countries, including Canada.85
Reactions have been ambivalent: some fear misuse of smart cards – the cards would be vulnerable to theft or fraudulent use by third parties – while others feel that use of these cards could actually enhance individuals’ control and privacy.86
New information technologies also pose significant challenges for the definition and enforcement of duties to protect privacy. For example, since a centralized database containing health records could be accessed from a number of different points in a con- nected system of computers, in contrast to a paper record which is physically located in one place, it may be difficult to determine who should bear the primary responsibility for ensuring that no unauthorized access takes place. Furthermore, physical security measures,87while essential, will not be sufficient to protect computerized records;
efforts must be made to build security into the system itself. Another enforcement prob- lem is that with computerized data, a breach of security may be difficult or impossible to detect. “In an electronic, on-line system, the data can be viewed, studied, and down- loaded from any location. The viewer of the information has not acquired any physical materials, making any theft virtually undetectable.”88
