An Approach To Masking Data For Privacy
I attended a talk at Stanford this afternoon on "Data Privacy" given by Sachin Lodha of the Tata Research Development and Design Centre in Pune, India. The talk was part of Stanford's Security Seminar series.
Earlier this month, Tata Consultancy Services announced it was going to invest $1 million to join a research project in this area at Stanford.
In his talk, Lodha described how he and his colleagues at Tata were approaching the increasing requirements from Tata's clients for much better protection of data when provided for testing purposes.
He outlined several techniques for "data masking" and described how they were supported in Tata's "Maskateer" product that's being used for generating privacy-protected test databases from actual client production data.
He also identified several areas requiring further research including how data masking might be extended to protecting non-database structures such as graphs or state tables.
Lodha was accompanied this afternoon by Professor Harrick Vin of the Department of Computer Sciences at the University of Texas at Austin who's also now working with Tata on research in this area.
