Why is this relevant to libraries? I think it’s past time that we start paying very close attention to the details of our data in ways that we have, at best, hand-waved as a vendor responsibility in the past. There have been amazing strides lately in libraryland in regards to the security of our data connections via SSL (LetsEncrypt) as well as a resurgence in anonymization and privacy tools for our patrons (Tor and the like, thank you very much Library Freedom Project).
Data about our patrons and their interactions that isn’t encrypted at rest in either the local database or the vendor database hosted on their servers (and our electronic resource access, and our proxy logins, and, and, and…) is data that is subject to subpoena and could be accessed in ways that we would not want. It is the job of the librarian to protect the data about the information seeking process of their patrons. And while it’s been talked about before in library circles (Peter Murray’s 2011 article is a good example of past discussions) this court case brings into focus the lengths that some aspects of the law enforcement community will go to in order to have the power to collect data about individuals.
