This system is for the privacy of internet user and finding the location of the mobile device should it become lost or stolen.The main goals of such systems are seeminglycontradictory to hatch the devices legitimately-visitedlocations from third-party services and other parties (locationprivacy) while simultaneously using those sameservices to help recover the devices location(s) after itgoes wanting (device-tracking). We propose a system,named Adeona, that nevertheless meets both goals.Itprovides strong guarantees of location privacy while preservin gthe ability to efficiently track missing devices.The system Adeona allows the user to draw browsing privacy and also the ability to track a missing device.We build a version of Adeona that uses OpenDHT as thethird party service, resulting in an right away deployablesystem that does not rely on any single trusted thirdparty. The system uses Open DHT which is a third party service which gives a immediately deployable systemWe describe numerous extensions for the basic designthat increase Adeonas suitability for particular deploymentenvironments.With numerous extensions for the design to increase deployment environmentsProvide a 1-2 page summary for each of the papers.What is the ... ...y and privacy, but one can doso in practice for real systems.We implemented Adeona, a full privacy-preservingtracking system based on OpenDHT that allows for immediate,community-orientated deployment. Its coremodule, the cryptographic engine that renders locationupdates anonymous and unlinkable, can be easily used infurther deployment settings. To estimate Adeona, we rana field trial to gain experience with a deployment on realusers systems. Our conclusion is that our approach issound and an immediately practicable alternative to trackingsystems that offer less (or no) privacy guarantees. Lastly,we also presented numerous extensions to Adeona thataddress a range of issues disparate deployment settings,increased functionality, and improved security. The techniquesinvolved, particularly our tamper-evident FSPRG,are likely of independent interest.
