Microsoft(s MSFT) Research has developed a new framework for automatically figuring out which lines of code inside massive systems might conflict with corporate privacy policies. It’s an important goal in today’s technology world where ever-present threats of data breaches and lawsuits, as well as the specter of looming government regulation, have smart companies preparing for whatever might come their way.
The really novel thing about Microsoft’s framework is that it was designed to bring together teams of personnel that might never interact directly otherwise, so that the compliance process is faster and less prone to errors. The system involves a high-level language called Legalease, which lets lawyers and policy employees encode corporate privacy policies into a machine-readable format, and a tool called Grok that inventories big data systems and checks them against those policies.
“Ultimately, the truth about what’s happening with this data is in the code,” researcher Saikat Guha explained.
But with millions of lines of code (a fair amount of which changes daily) in a product such as Bing — on which the Microsoft Research project was prototyped — it can be difficult to figure out what data is being stored where, how it’s being used as part of any given job and whether that usage complies with privacy rules. The current compliance process is time-consuming: lawyers write policies, privacy personnel interpret them to developers, developers write code and then auditors periodically check in to make sure the code complies.
Guha and his team hope the new framework will speed the process and make it more accurate by letting all of these steps occur in parallel. Lawyers and privacy personnel can encode their policies using Legalease and run them against Grok to identify code that might be affected. Privacy managers can then, for example, approach developers with the couple thousand lines of code that might be affected. This way, developers don’t waste time trying to figure which code needs changing and how to change it, and auditors can continuously check whether code is in compliance.
Guha analogized the project to creating a map of the city, where Grok is the map itself and Legalease is the legend. Lawyers and privacy managers might be like city planners who, upon identifying a problem or crafting a new policy, could approach developers and say, “‘We understand which part of the city you’re working in, where your neighborhood is and exactly what you need to do,'” he explained.
If they get lost while working, the policies encoded using Legalese should help them figure out they need to do.
Although it’s just a project — and one developed at Microsoft, at that — it’s easy to see the ramifications of this type of framework across the web. Companies such as Google(S GOOG) and Facebook(S FB) are also trying to manage privacy across increasingly larger and more complex systems. Sometimes this is proactive, but new proposed rules governing data brokers and web privacy in general might eventually begin to apply some external pressure.
“This [framework],” Guha said, “really sets us up to be a lot more active when it comes to understanding whatever policy decisions are being made.”
