Obfuscation

In the CacheCloak model, your phone predicts your possible paths and then fetches the results for several likely routes. As you move, you receive the benefits of locative awareness—access to what you are looking for, in the form of data cached in advance of potential requests—and an adversary is left with many possible paths, unable to distinguish the beginning from the end of a route and unable to determine where you came from, where you mean to go, or even where you are. From an observer’s perspective, the salient data—the data we wish to keep to ourselves—are buried inside a space of other, equally likely data.
