PRISM and privacy: will this change everything?

This number will be updated

Climate change and rising energy costs will change everything: a new mindset and action plan for 21st century public health.

Western governments currently prioritize economic growth and the pursuit of profit above alternative goals of sustainability, health and equality. Climate change and rising energy costs are challenging this consensus. The realization of the transformation required to meet these challenges has provoked denial and conflict, but could lead to a more positive response which leads to a health divide...

Will Theory of Everything save earth?

The story is a mix of futurology, science fiction, new technical ideas, science, science ideas of author [1, 2, 3, 4], and philosophy. The style is similar as in the paper of Makela [5]. On an example of crisis of overpopulated human species in future, it is described how to develop a theory of everything, how to give more sense to amateur science, and how reactions of professional science rega...

PRISM — Privacy-Preserving Search in MapReduce

We present PRISM, a privacy-preserving scheme for word search in cloud computing. Assuming a curious cloud provider, privacy of data stored in the cloud becomes an issue. The main challenge in the context of cloud computing is to design a scheme that achieves privacy while preserving the efficiency of cloud computing. Main approaches like simple encryption, Private Information Retrieval (PIR) a...

PRISM - Privacy-Preserving Search in MapReduce

We present PRISM, a privacy-preserving scheme for word search in cloud computing. In the face of a curious cloud provider, the main challenge is to design a scheme that achieves privacy while preserving the efficiency of cloud computing. Solutions from related research, like encrypted keyword search or Private Information Retrieval (PIR), fall short of meeting real-world cloud requirements and ...
