Licensed processing of encrypted information

We report on work in progress concerning a computational model for data processing in privacy. As a core design goal here, we will focus on how the data owner can authorize another party to process data on his behalf. In that scenario, the algorithm or software for the processing can even be provided by a third party. The goal is here to protect the intellectual property rights of all relevant players, while retaining an efficient system that allows data processing in distrusted environments, such as clouds.
