Jeff Jonas writes about the challenges of managing data privacy when the data concerned is Big Data. He advocates taking a real-time approach to auditing user behavior:

** Real-time active audits**. It is now going to be essential that user activity be more rigorously analyzed, in real-time, for inappropriate behavior.  Audit logs have actually been part of the problem – just another big pile of data – evidence of misuse hiding in plain sight against the backdrop of millions and millions of benign audit records.

I must say, it hadn’t occurred to me that privacy management could be seen as a real-time data problem. But he’s right that large data sets, when not acted upon immediately, can become part of the problem. In his words, “just another big pile of data”.
