‘Melbourne Shuffle’ secures cloud data

Dance steps

Usage patterns — which files computer users access in the cloud, when and how often — could signal anything from a contemplated IPO to impending bankruptcy. The Melbourne Shuffle disguises those digital footprints, making even encrypted data safer.

Encryption might not be enough for all that data stored in the cloud. An analysis of usage patterns — which files are accessed and when — can give away secrets as well. Computer scientists at Brown have developed an algorithm to sweep away those digital footprints. It’s a complicated series of dance-like moves they call the Melbourne Shuffle.
