Privacy Implications of RFID technology
Presented by: Patrick Dillon, Reference Librarian, University of Massachusetts, Boston
Patrick Dillon noted that most of the items consumers purchase will have RFID tags by 2007. Hand-held readers are getting smaller all the time, and are therefore less obvious in public settings. While citizens give up a great deal of information voluntarily (with grocery store cards, EZ Pass technology for paying tolls, etc.), with RFID they do not even know that it is happening. RFID readers could be discreetly placed anywhere to create "Hot Lists" of what people are carrying and where they are going. The alarmist interpretation of this situation is that "Big Brother is watching you."
One solution to privacy concerns in retail is to "kill" the tag upon purchase (tag no longer transmits data once the item has been bought). However, libraries cannot use that technology, since books are checked out and in many times over, so we need to be very careful about how much and what kind of information we store on these tags.
Privacy concerns regarding use of RFID in libraries are being addressed in a number of ways. Mr. Dillon also referred to the recent legislation passed in California. He noted that the San Francisco Public Library received the funding needed for implementing RFID, but the Board of Trustees voted it down. One serious concern is that that the standard code currently used in library tags cannot be encrypted, so the data stored on that tag is not secure.
Mr. Dillon also described an "RFID Bill of Rights" being proposed by Simpson Garfinkel, a leader in the field of RFID technology. It is based on previously developed Fair Information Practices, and suggests that users of RFID systems and those who purchase items that contain RFID tags have:
Mr. Dillon suggests that libraries are violating the second and third of these proposed rights - the right to deactivate the tag upon "purchase" (check-out) and the right to an alternative method that affords them the exact same privileges and services as those using RFID.
RFID Tag Implementation at Providence College
Presented by: Jim Salisbur, Head of Access Services, Providence College
Jim Salisbury spoke about the experience of implementing RFID at Providence College. It began after the library conducted an inventory of the library collection, a process that took eleven months to complete.
Report by:
One challenge they encountered was that there were six different security detection tags used throughout the collection, and all of these tags had to be physically removed since the metal in them could interfere with RFID tags. Another challenge emerged in the actual conversion process. Although they were using conversion stations, some of the aisles were not wide enough to accommodate them, and so books had to be taken off the shelves and converted elsewhere. Conversion was proceeding very slowly until they developed a workflow that streamlined the process.
There have been many advantages to implementing RFID. Only 242 of the 350,000 items in their collection remain unaccounted for. Shelf reading and inventories are much easier and more efficient. The inventory project that took eleven months to complete before RFID can now be done three times per year.
There have been some challenges as well. Because Providence College shares its catalog with a consortium, updates take a little longer than they would in a stand-alone ILS. On a related note, they chose to continue barcoding their books because their Interlibrary Loan partners in the consortium do not yet have RFID, and even if they did, different RFID systems are not always compatible with one another. Faculty were very skeptical at first, primarily because of concerns about privacy, but Salisbury reported that they have come around. Student workers like the system.
Mr. Salisbury was asked about staffing and workflow issues. He noted that they have chosen not to install a self check-out/in kiosk, because Providence is known for its "high touch" environment. While some staff positions were reallocated as a result of RFID implementation, no positions were cut.
In closing, Salisbury noted that it RFID implementation had been a long, sometimes challenging, process, but it created a sense of community among the staff, and the benefits have outweighed the drawbacks.
