Building an International Network of Shared Metadata

Libraries tend to avoid collecting any sort of long-term data about patron library usage or preferences wherever possible. Although this is done to protect patron privacy, it also greatly restricts the range of social features (such as suggestions based upon a patron's checkout history or patron-supplied reviews and comments) that library catalogs can offer.

I will discuss cryptographic techniques for securely and anonymously collecting and sharing user-supplied metadata across library systems.
