Mit #PrettyGoodPhonePrivacy
dessen Name augenzwinkernd an die PGP-Verschlüsselung für E-Mails erinnert, zieht das US-Startup Invisv viel Aufmerksamkeit auf sich. Die Firma wirbt mit den Namen der Sicherheits- und Datenschutzexperten Bruce Schneier u. Jon Callas als Berater u. verspricht eine Tarnkappe für Smartphones, die sogar vor den Augen von Mobilfunknetzbetreibern schützt.

Here's another example of the #decoupling principle: when you're on a mobile network, we've always assumed that your location and everything you do has to be trackable by the mobile provider, because the tower needs to be able to talk to your phone.

With #PGPP, we showed that we can provide mobile data service while separating the *who* -- your actual identity (the person paying the bill) -- from the *what* -- the identifier the mobile network knows your phone as (your SIM's IMSI). 7/

We're working to improve #metadata #security and #privacy and are looking forward to talking with you all #introduction. Fixing this is complex and layered. We've built a few unique services and have more coming:

1. #PGPP (Android) -- mobile data service with metadata (IMSI / IP) privacy
2. #Relay (Android) -- decouples Internet traffic across two parties
3. #Booth (in browser) -- video conferencing where the server can't see participants (IP / identity) or data (video / audio)

Pretty Good Phone Privacy: privacy-preserving mobile service

#PGPP is a fundamentally new type of service to provide mobile and Internet privacy. PGPP helps to protect users against types of #tracking that previously couldn't be prevented: the tracking of your location by your globally-unique IMSI.

@DigiOekCH Pretty Good #Phone Privacy - grobe Übersetzg: aus Forschung 2021 gibt es jetzt ein #PGPP Beta-Angebot: Verhindert angebl #Tracking der global eindeutigen #IMSI Identifizierung, auch durch #Mobilfunknetzbetreiber selber. Erreicht durch:
(1) IMSI #Randomisierung mit #eSIM auf unterstützten #Android -Geräten;
(2) #Relay, ein Service für sog. entkoppelte #Internet #Privatshäre, verbirgt IP-Addresse, mit/ohne eSIM.

Des chercheurs américains ont lancé le service Pretty Good Phone Privacy (#PGPP) qui a la bonne idée de découpler l’authentification de l’abonné de sa connexion au réseau.

#PGPP Pretty Good #Phone Privacy: Interesting #concept, supposedly prevents #tracking by globally-unique #IMSI incl. #attacks by #mobile carriers themselves. Apparently achieved by:
(1) privacy-preserving IMSI #randomization using #eSIM on supported #Android devices;
(2) Relay, #decoupled #Internet #privacy, #hiding IP address, with/without eSIM.
