WebAug 10, 2012 · The Cornell researchers used an approach called crowd-blending privacy, which involves limiting how a data set can be analyzed to ensure that any individual record is indistinguishable from a large group of other records. "The hope is that because crowd-blending is a less strict privacy standard it will be possible to write algorithms that will ... WebCrowd-blending privacy [14] relaxes the notion of dif-ferential privacy, allowing an attacker to learn something about an individual, if this feature is sufficiently common to be considered not sensitive. Crowd-blending privacy employs the notion of 𝜖-blending. individual in dataset with respect to privacy-preserving mech-anism San if it holds

WebCrowd-Blending Score. A data set with only 1 reporter is unique and easy to trace. In the prediction section, the crowd blending score is a site indicator that scores how well certain fingerprints blend in with others (strictly collected on the same site). Data scores decline by data uniqueness; Final score is the minimum of all data scores WebCrowd-sourced sensing systems allow people to voluntarily contribute sensor data from mobile devices. They enable numerous applications, including weather and traffic …
