I was reminded of that old chestnut about a flagman having to walk in front of early automobiles when I heard some participants talk at the workshop on big data, social good and privacy. Imagine imposing inform and consent rules on transaction-generated data (big data) belonging to large corporate entities such as mobile operators. They need the data on user mobility patterns to manage their networks; they need financial transaction data to manage their finances. All these things can be covered under broad inform and consent procedures that will be presented to customers as they sign up. What will not be possible would be to permit use by third parties for traffic management, energy management, urban planning etc, since these uses could not be conceptualized at the time of signing up customers.
