Differential Privacy has recently emerged as a measure for protecting privacy in distorted data. While this seems to solve many problems, in practice it still leaves a number of security challenges, and even raises new ones. We give an example of a secure two-party dot product protocol and use this as an example to demonstrate a number of challenges arising from the interaction of information security and differential privacy. We show that independently meeting the requirements of secure multiparty computation and differential privacy does not result in a solution meeting the real goals of privacy and security. Through this, we outline challenges and opportunities for further research.
