- The absurd alarmism over the new Facebook Messenger App’s privacy settings
- Brazil’s move to ban anonymity
- How the secrecy of the secret app has been compromised
- and finally how Tor users were put at risk by a fake website
In a brilliant campaign, IO9 and the EFF is having cosplayers pose with pro-anonymity, pro-privacy, and pro-pseudonymity signs. See the whole set here. The most popular seems to be “I have a right to a Secret Identity!”.
It turns out that people say nasty things under their real names, and people also say valuable things anonymously.
It is amazing how often I see respected academics and other thinkers get incredibly sloppy in their reasoning when it comes to anonymity. They frequently assume correlations for which they have no evidence, and propose solutions with no consideration of the consequences.
I appreciate the rational perspective in articles like this.
This article describes a clever attack against Secret, the “anonymous” secret sharing app.
Their technique allows the attacker to isolate just a single target, so any posts seen are known to be from them. The company is working on detecting and preventing this attack, but it is a hard problem.
In general, any anonymity system needs to blend the activity of a number of users so that any observed activity could have originated from any of them. For effective anonymity the number needs to be large. Just pulling from the friends in my address book who also use Secret is way too small a group.
A Brazilian court is enforcing a constitutional ban on anonymity by requiring Apple and Google to remove Secret, an anonymous social network chatting app from their app stores. Microsoft is being required to remove Cryptic, a similar windows phone app.
In addition to that, they have been ordered to remove the app from the phones of all users who have installed it. These kinds of retroactive orders to have companies intrusively modify the contents of all of their customer’s devices are concerning. At least these apps are free, if users had paid for them, that would introduce another complication.
One wonders how this will apply to tourists or business travelers visiting Brazil. Will their phones be impacted as well?
The law exists to allow victims of libel or slander to identify and confront their those speakers.
While this ruling only applies to Apple, Google, and Microsoft, and only with respect to the Secret and Cryptic apps, the underlying principle extends much further. There are still final rulings to come, so this is not the last word on this situation.
Anonymizer has had a great many Brazilian customers for many years. Anonymizer provides those users important protections which are well established in international human rights law. We certainly hope that they will continue to be allowed to use our services.
