Doug Henschen of Information Week recently shared his thoughts on the less-than-nefarious intent of the NSA’s PRISM Big Data tools. He writes, “It’s understandable that democracy-loving citizens everywhere are outraged by the idea that the U.S. Government has back-door access to digital details surrounding email messages, phone conversations, video chats, social networks and more on the servers of mainstream service providers including Microsoft, Google, Yahoo, Facebook, YouTube, Skype and Apple. But the more you know about the technologies being used by the National Security Agency (NSA), the agency behind the controversial Prism program revealed last week by whistleblower Edward Snowden, the less likely you are to view the project as a ham-fisted effort that’s ‘trading a cherished American value for an unproven theory,’ as one opinion piece contrasted personal privacy with big data analysis.”

He continues, “The centerpiece of the NSA’s data-processing capability is Accumulo, a highly distributed, massively parallel processing key/value store capable of analyzing structured and unstructured data. Accumolo is based on Google’s BigTable data model, but NSA came up with a cell-level security feature that makes it possible to set access controls on individual bits of data. Without that capability, valuable information might remain out of reach to intelligence analysts who would otherwise have to wait for sanitized data sets scrubbed of personally identifiable information.”
