To keep data safe in the cloud, a group of computer scientists suggests doing the Melbourne Shuffle.

That may sound like a dance move, but it’s also a computer algorithm developed by researchers at Brown University.

The computing version of the Melbourne Shuffle aims to hide patterns that may emerge as users access data on cloud servers. Patterns of access could provide important information about a dataset — information that users don’t necessarily want others to know — even if the data files themselves are encrypted.

“Encrypting data is an important security measure. However, privacy leaks can occur even when accessing encrypted data,” said Olga Ohrimenko, lead author of a paper describing the algorithm. “The objective of our work is to provide a higher level of privacy guarantees, beyond what encryption alone can achieve.”
