Given the significant risk of harm to individuals stemming from data re-identification, it is imperative that the SJC account for data identifiability in determining which information in court records will be made accessible to the public through its soon-to-be-launched digital system.  Data identifiability is a factor wholly separate and distinct from the sensitivity of data.  It exists in varying degrees along the de-identification spectrum.

In its 2012 report, “Protecting Consumer Privacy in an Era of Rapid Change, the FTC concluded that the process of removing personally identifiable information (PII) from data is not a silver bullet, acknowledging the broad consensus that “the traditional distinction between PII and non-PII

In today’s big data world, given the sophistication of data handlers, it is well-recognized that de-identification alone is not enough to prevent re-identification of
