A Reminder about Deleting Data

July 15, 2019

If you believe data are deleted, you may want to take a deep breath and read “Good Luck Deleting Someone’s Private Info from a Trained Neural Network – It’s Likely to Bork the Whole Thing. Researchers Show Limited Success in Getting Rid of Data.”

With a title like this, there’s not much left to say. We did note this one, cautious quote:

Zou [a whiz researcher] said it isn’t entirely impossible, however. “We don’t have tools just yet but we are hoping to develop these deletion tools in the next few months.”

Will there be such tools? I have been stumbling along with databases since the 1960s, and deletes which delete are still not available.

Just a reminder that what one believes is not what happens within data management systems.
