Spearphone: A Speech Privacy Exploit via Accelerometer-Sensed Reverberations from Smartphone Loudspeakers
In this paper, we build a speech privacy attack that exploits speech reverberations generated from a smartphone's inbuilt loudspeaker captured via a zero-permission motion sensor (accelerometer). We design our attack, called Spearphone2, and demonstrate that speech reverberations from inbuilt loudspeakers, at an appropriate loudness, can impact the accelerometer, leaking sensitive information about the speech. In particular, we show that by exploiting the affected accelerometer readings and carefully selecting feature sets along with off-the-shelf machine learning techniques, Spearphone can successfully perform gender classification (accuracy over 90%) and speaker identification (accuracy over 80%). In addition, we perform speech recognition and speech reconstruction to extract more information about the eavesdropped speech to an extent. Our work brings to light a fundamental design vulnerability in many currently-deployed smartphones, which may put people's speech privacy at risk while using the smartphone in the loudspeaker mode during phone calls, media playback or voice assistant interactions.

#CalyxOS the privacy and security focused #Android fork now has early support for the #Xiaomi #MiA2
A MiA2 running CalyxOS is probably now the most secure / private budget smartphone available
As it is an Android One phone it will get full monthly security updates from Xiaomi for another two years, Calyx will incorporate these and push them onto their users.

If you read and enjoy my travel posts through my website or Mastodon* and you are planning to travel to somewhere I've been and you can't afford an actual travel agent and you find travel planning too stressful or time consuming to fit into your life, I would be delighted to share advice.
My specialties are land and sea (not air) transit, especially long distance European buses, and finding vegan food. I'm happy to also help with general stuff to do, and even more in-depth help with planning and realistic budgeting if you want because I actually love wasting away hours and days researching travel stuff.

@privacylab "One recent study found that Amazon is the second most-trusted institution of any kind in the United States, ahead of Google, the police, and the higher-education system, and trailing only the U.S. military."

@bstacey godd did you hear about the situation in germany? because it's incredible
basically, the German Conference of University Deans ("HRK"), in a moment of unlikely clarity, decided that they were Tired Of This Shit and told all the publishers that from now on all german universities would make one large agreement with them, on the universities terms, for access
elsevier and springer made offers so laughable that the HRK actually literally wrote a press release about how they should "come back to the table when they're ready to make a serious offer" and since then many universities have just kind of let access contracts expire
they recently came to an agreement with wiley, rest is still ? ? ? ? ?
it's fantastic because every day this goes on is a day more scientists learn about the greatest development in science access of this century, which, lets be quite honest, is scihub

Kate Raworth's "doughnut" does a nice job of expressing the objectives of economic development in the #anthropocene, but says nothing about the "how," leaving a vague taste of global state and NGO campaign for reforms.
This is where I find @luisrazeto, and other theorists of #SolidarityEconomy useful. But I think we still need to re-articulate solidarity economy on the basis of the climate crisis: if it "changes everything", the changes need to be understood in solidarity economy, too.
