Mapping Health Data: Improved Privacy Protection With Donut Method Geomasking

Mapping health data: improved privacy protection with donut method geomasking.

A major challenge in mapping health data is protecting patient privacy while maintaining the spatial resolution necessary for spatial surveillance and outbreak identification. A new adaptive geomasking technique, referred to as the donut method, extends current methods of random displacement by ensuring a user-defined minimum level of geoprivacy. In donut method geomasking, each geocoded addres...

Difference Distribution Attack on DONUT and Improved DONUT

Vaudenay[1] proposed a new way of protecting block ciphers against classes of attacks, which was based on the notion of decorrelation. He also suggested two block cipher families COCONUT and PEANUT. Wagner[2] suggested a new differential-style attack called boomerang attack and cryptanalyzed COCONUT'98. Cheon[3] suggested a new block cipher DONUT which was made by two pairwise perfect decorrela...

Privacy - DRM : Data Protection by Copy Protection ?

Protecting media contents and enforcing privacy policies seem to be related problems: mechanisms are needed to restrict data processing outside the copyright holder’s, respectively data subject’s, domain of control. A systematic analysis of requirements, properties, and experiences with digital rights management (DRM) reveals substantial differences between Content-DRM to protect media contents...
