Technical and non-technical teams often lack a shared vocabulary, making collaboration difficult. There are, however, ways to surmount this hurdle and engage in a productive working relationship through which effective privacy tools can be built. The privacy engineering and legal teams at Uber did just that in building their privacy platform. The Cybersecurity Law Report spoke to them about how they worked together to accomplish this. In this first installment of our two-part article series on legal and engineering collaboration at Uber, we look at how the company structures its privacy team and how it created and implemented its differential privacy tool, including how the tool helps with GDPR compliance. Part two will offer insight from both teams about how to build bridges between the engineering and legal professionals.
