While unfamiliar to a large number of library users, RFID (radio frequency identification) technology is becoming more and more prevalent in library systems. As implied by the name; RFIDs are small chips that are able to emit a signal that identifies the object to which it is attached. Necessary to read these signals are scanners that can receive the signal and computer software that is required to translate the signal into something readable by humans or cataloguing software.
The traditional method of checking in and out books that most libraries have been using for years involving barcodes and manual scanners has been criticized for being too slow, and causing “long queue, bottle necking and complains from dissatisfied patrons (1). RFIDs are becoming more and more attractive as an alternative to the barcode system for a number of reasons; the first being that they are faster. Because they use a frequency rather than a printed code a scanner does not need to be aimed or directly applied, as well a RFID scanner can pick up the frequency of many RFIDs at a time, further speeding up the process. RFIDs can also be used to store data; which can either be written over or read and they can contain a large amount of information. Numerous sources have expressed the ways that libraries can use this function such as to keep track of the; item code, a brief description of the item, and even the circulation history of the item (1). RFID technology has also been a proposed solution to the “information gap” phenomena which is what occurs when the status of a book may be incorrect because of the limitations of the computer system. Essentially, when the computer catalogue says that a library book is on a shelf, when in fact it has been checked in but not yet been put in its place, or another patron either currently has it or has moved it (1). Another function that the RFIDs can serve is a security measure to reduce the threat of stolen library property.
Introducing RFID technology to libraries is not an easy task, it would involve the installation of a large amount of new hardware and software into the library, staff would need to be trained on the new system
and there are a number of privacy and security concerns that arise from the use of RFID technology that will need to be considered. One of the primary concerns is that since the RDID tags have the capability to store information, they will record personal information that can then be viewed by others who have the technology required to do so. There is also concern that the RFID scanners in the library will be able to pick up signals from other RFID chips that the patron might have on them (which is growing increasingly likely as RFID technology becomes more popular, it can be found in a number of common items including; drivers licenses, money, car keys, passports...)
Discussions about these concerns is problematic because there isn't a consensus in the literature as to whether or not these concerns are legitimate. For example in their conclusion Pop et. al. state that,
“the tags are “powerless”, have a very small read range, store a minimum amount of data (normally a barcode) and carry no patron data on the tags. All these factors make privacy concerns almost non-existent at this time (2011, p. 272).”
On the flip side the list of uses mentioned earlier, “item code, a brief description of the item, and even the circulation history of the item” were taken from an article written the very same year (Wu, et. al., 2011). These fears seem valid when we learn that some libraries the the Oakland Public Library had been leaving their tags unlocked. While this makes sense from the management perspective as having the tags unlocked meant that library staff are able to make changes to the data, it also leaves the tags open to vandals or other individuals who are able to access the tags using commercially produced RFID readers. There are also threats beyond people just accessing the data currently on a RFID chip, Lukas Grunwald, a German security expert has been able to program a tool that would allow him to install “cookies” onto RFID chips. These cookies can be used in the same way that they are online, to track users. For example, “s, a stalker could, say, place a cookie on his target's E-ZPass, then return to it a few days later to see which toll plazas the car had crossed (and when).”
In order to address these concerns a number of different organizations have created various sets of guidelines in order to protect libraries and patrons. But again, very little consensus has been reached in regards to how to protect library patrons and what kinds of information needs to be protected.
Is the convience and time savings that RFID technilogy can offer worth the security risk? Does it really matter when we are already sharing so much informatio about ourselves both willingly and unknowingly?
