Just Published! Library Data Risk Assessment Guide

Welcome to this week’s Tip of the Hat!

To build or to outsource?

Building an application or creating a process in a library takes time and resources. A major benefit of keeping it local, though, is that libraries have the greatest control over the data collected, stored, and processed by that application or system. Conversely, a major drawback of keeping it local is the sheer number of moving parts to keep track of in the building process. Some libraries have the technical know-how to build their own applications or have the resources to keep a process in house. Keeping track of privacy risks is another matter. Risk assessment and management must be addressed in any system or process that touches patron data, so how can libraries with limited privacy risk assessment or management experience make sure that their local systems and processes mitigate patron privacy risks?

Libraries have a new resource to help with privacy risk management! The Digital Library Federation’s Privacy and Ethics in Technology Working Group (formerly known as the Technologies of Surveillance Working Group) published “A Practical Guide to Performing a Library User Data Risk Assessment in Library-Built Systems“. This 28-page guide provides best practices and practical strategies in conducting a data risk assessment, including:

  • Classifications of library user data and privacy risk
  • A table of common risk areas, including probability, severity, and mitigation strategies
  • Practical steps to mitigate data privacy risks in the library, ranging from policy to data minimization
  • A template for readers to conduct their own user data inventory and risk assessment

This guide joins the other valuable resources produced by the DLF Privacy and Ethics in Technology Working Group:

The group also plans to publish a set of guidelines around vendor privacy in the coming months, so be sure to bookmark https://wiki.diglib.org/Privacy_and_Ethics_in_Technology and check back for any updates!

Contact Tracing At The Library

Welcome to this week’s Tip of the Hat!

Contact tracing has been used in the past with other diseases which helped curve infection rates in populations, so health and government officials are looking at contact tracing once again as a tool to help control the spread of disease, this time with COVID-19. There have been various reports and concerns about contact tracing through mobile apps, including ones developed by Google and Apple. However, mobile contact tracing will not stop local health and government officials in taking other measures when it comes to other contact tracing methods and requirements, and libraries should be prepared when their local government or health officials require contact tracing as part of the reopening process.

While there are no known cases of libraries doing contact tracing as part of their reopening process, there are some ways in which libraries can satisfy contact tracing requirements while still protecting patron privacy.

Collect only what you absolutely need

What is the absolute minimum you need to contact a patron: name, email address, and/or telephone number are all options. Sometimes patrons do not have a reliable way of contacting them outside the library – health and government officials should have recommendations in handling those cases.

But what about having patrons scan in with their library card and using that as the contact tracing log? What seems to be a simple technological solution is, in reality, one that introduces complexity in the logging process as well as privacy risks:

  • Some of the people visiting the library will not have their library card or are not registered cardholders.
  • Contact logs can be subject to search or request from officials – maintaining the separation between the contact log and any other patron information in the library system will minimize the amount of patron data handed over to officials when there is a request for information.

Paper or digital log?

Some libraries might be tempted to have patrons scan in with their barcodes (see above section as to why that’s not such a good idea) or keep an electronic log of patrons coming in and out of the building. However, an electronic log introduces several privacy and security risks:

  • Where is the digital file being stored? Local drive on a staff computer that isn’t password protected? Network storage? Google Drive (yikes!)?
  • Who has access to the digital file? All staff in the library?
  • How many other copies of the file are floating around the library’s network, drives, or even printed out?

In this instance, however, a paper log will provide better privacy and security protections when you take the following precautions:

  • The paper log should be securely stored in a locked cabinet or desk in a secured area, preferably a locked office or other controlled entry space.
  • During business hours, the paper log should be filled out by designated staff members tasked to collect information from patrons. Do not leave the paper log out for patrons to sign – not only you give patrons the names of others in the building (for example, a law enforcement agent can read the log and see who’s in the building without staff knowledge) you also potentially expose patrons and staff to health risks by having them share the same hard surfaces and pen.
  • Restrict access to the paper log to only staff who are designated to keep logs, and prohibit copying (both physical or electronic copies) of the log.

Equitable service and privacy

Some patrons might not have reliable contact information or might refuse to give information when asked. If the local government or health officials state that someone can’t enter a building if they don’t provide information, how can your library work with your officials in addressing the need for libraries to provide equitable service to all patrons who come to the library?

Retention and disposal

Keep the contact tracing logs for only as long as the government or health officials require. If there is no retention period, ask! Your logs should be properly disposed of – a paper log should be shredded and the shredded paper should go to a secured disposal area or service.

Keeping a log of visits to the library is something not to be taken lightly – you are creating a log of a patron’s use of the library. Several other privacy concerns might be specific to your library that could affect how you go about contact tracing, such as unaccompanied minors. Contact tracing is an effective tool in containing disease outbreaks in the past, but it doesn’t have to come at the expense of losing entire personal privacy if the library works with its staff and government officials in creating a process that minimizes patron data collection, access, and retention.

Choose Privacy Week Recap

Welcome to this week’s Tip of the Hat!

This weekend was hot in Seattle, with temperatures near 90 F. While the Executive Assistant took this time to bask in this heat, we at LDH tried to find a cool spot in the home office to work, away from the Executive Assistant’s gaze.

Last week was a busy week on the Choose Privacy Every Day site for Choose Privacy Week! Here’s what you might have missed:

  • Virtual Programming and Patron Privacy – Jaime Eastman along with the ALSC Children and Technology committee give much-needed guidance for library workers who are moving children-oriented programs and services online due to the pandemic. The post goes into the Children’s Online Privacy Protection Act (COPPA), and what library workers need to do to protect the privacy of children while keeping in compliance with COPPA. Bookmark the ALSC Virtual Storytime Services Resource Guide for additional guidance (coming soon!).
  • Protecting Privacy In A Pandemic: A Resource Guide – On Friday, May 8th, OIF hosted a Privacy Town Hall about patron privacy. While we wait for the recording of the Town Hall event, the blog post lists the main topics and resources covered by the panelists in the Town Hall.
  • When libraries become medical screeners: User health data and library privacy – Some libraries are now giving medical screenings to patrons who want to enter the library building. What privacy risks are there in collecting health data of your patrons? Read the article by LDH to find out why library workers might not be the best choice in handling health data.

Finally, if you have that one library privacy topic that you’ve been meaning to write about or if you want to share your privacy thoughts to a wide audience, Choose Privacy Every Day is looking for blog authors! There are some requirements for being an author for the blog, but this is a great opportunity to get your ideas and thoughts out into the library world.

That’s a wrap! Or, at least, the computer core temperature says it’s time to put the computer in the freezer. If you’re on the West Coast, stay cool, and for those of you who got snow on the East Coast, stay warm!
