This is a similar idea to something I've been working on for quite a long time (since June of last year, actually)[1]. I have experience with graph-generating software used by Five Eyes governments to map relationships, and I've been developing software that will dilute the effectiveness of those graphs by generating tons of noise across the system. Now it's a half-finished Chrome extension, but my hope was to build a complete set of browser extensions, and then bleed the design to Android/iOS to help dilute the graphs of people's phone behavior.
