- Enables Base DNA (RFC4436) functionality
* Randomised ordering (opt: dna_random <integer> [1: Enable randomised ordering of DNA requests])
- This mechanism provides for randomised delivery of candidate link layer addresses in the DNA reachability tests, so as to enhance the location privacy with respect to the location and time-based analysis of the device's movement patterns.
* Dummy addresses (opt: dna_dummy <integer> [0-N: Number of dummy addresses, -1: Automatic choice of number of dummy addresses])
- This mechanism allows for the introduction of dummy addresses into the DNA reachability tests to enhance location privacy, with respect to location identification and time-based analysis of the device's movement patterns.
- With the R2 release, we introduce a new option that provides for automated the choice of the number of dummy addresses.
* Pre-analysis phase of the address privacy metrics (opt: dna_preanalysis <integer> [1: Enable use of geolocation based pre-filtering of DNA requests]; opt: dna_geourl <string:URL> [URL to be used for geolocation (Google Geolocate json-based API e.g. https://www.googleapis.com/geolocation/v1/geolocate?key=GOOGLE_API_KEY )
- This mechanism allows for the set of existing candidate link layer (MAC) addresses for DNA to be analysed once assigned but before use in DNA to ascertain their privacy metrics with release Release v2. Specifically, we provide for the option to check and filter geolocatable candidate MAC address pairs so that a device can't be easily geolocated from their DNA reachability tests.
