#Chatkontrolle verhindern

Die EU-Kommission plant eine Verordnung, die Anbieter von Messenger-Diensten. E-Mail-Providern und anderen Kommunikationsdiensten verpflichten würde, private Nachrichten automatisiert zu durchsuchen und strafbare Inhalte zu melden. [1/x]

Dänemark will die Chatkontrolle in drei Wochen durchdrücken. Am Gesetz ändert die Ratspräsidentschaft nichts, stattdessen sollen Staaten ihre Meinung ändern. Die Position Deutschlands ist maßgeblich. ...

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/ge...

After having pointed out severe shortcomings of existing XAI paradigms and feature attribution methods in the past, I am happy to announce two novel methodological contributions, to be presented in this year's main track of the premier ML conference, NeurIPS.

Many of us assume that clicking “blur” or activating a virtual background protects our privacy. This research shows: that belief is misleading. The safest option is still the simplest one: prepare your real environment for calls instead of relying solely on digital masking.

The team developed an attack that exposed 53% more background pixels than previous methods, showing just how much information can unintentionally slip through.

These fragments are often invisible to the human eye, but when collected over time, they can be used to reconstruct rooms and even identify personal objects.

Virtual backgrounds leak tiny image fragments of the real environment – so-called pixel leaks.

These fragments are often invisible to the human eye, but when collected over time, they can be used to reconstruct rooms and even identify personal objects.

The “digital curtain” in video calls has holes – with the right techniques, people can see through.

New MLSec study (BIFOLD) reveals that virtual backgrounds in video conferencing tools are not a reliable privacy shield.

Trump admin planning to change student visas from lasting for duration of academic program to fixed 4-yr term, and then much harder to renew
Could destroy US ability to attract global talent, particularly those seeking advanced degrees in STEM. The median time to complete a PhD is 5.7 yrs per NSF.

Trump officials have proposed a new rule limiting international students to fixed periods of entry, making a U.S. education more precarious.
