I get PDFs watermarked to me by their placement of sections in relation to one another, their word choice in opening sentences of paragraphs, and figure/image locations within the PDF. The idea being that the content is the watermark, not some silly overlay watermark which is fairly easily stripped out in most free operating systems. -- Andrew http://tpo.is/contact pgp 0x6B4D6475 -- Unsubscribe, change to digest, or change password at: https://mailman.stanford.edu/mailman/listinfo/liberationtech ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE

Today is Your Day to Stop Real ID
by Bill Scannell 06 Jul '18

Dave, Can you put this out on wide-scan: it's important. All the best, Bill We have less than 48 hours to stop our nation from having a National ID card scheme. The US Senate is scheduled to vote either today or tomorrow on two amendments that will remove Real ID provisions from the immigration bill. Real ID is a very, very real national identification card. Sixteen states have passed legislation rejecting REAL ID: now it's time for the Senate to do their part. You can fax your Senators and take immediate action by visiting: http://unrealid.com/action.html 777 --- 777 777 --- 777 "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." - Benjamin Franklin ------------------------------------------- Archives: http://v2.listbox.com/member/archive/247/=now RSS Feed: http://v2.listbox.com/member/archive/rss/247/ Powered by Listbox: http://www.listbox.com ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE

Next news from Germany
by awxcnx＠web.de 06 Jul '18

06 Jul '18

Hi, I am a german TOR admin ("knuffel"). I have running a mixmaster remailer too ("awxcxn"). Both were running on a dedicated root server. Half a year ago I have had my first trouble with the german BKA. The hoster of my server got a letter from the BKA and closed my server without any respect to the law. I contact the press an a few days later the server was back and online. A few month ago I got an anonymous tip, a telecommunication surveillance is/was running against me and I am listed in a "known" database. Over the last months, I tried to figure out, what happens. I contact the data protection official of Germany for help. Like me, he did not get any information because the prosecution denied any information with the reason: "Any information will compromise the security of Germany or one of its parts." ( ' 19 Absatz 6 Bundesdatenschutzgesetz ) I compromise the security of Germany, seems I am a terrorist or something like that. The anti-terrorism-law in Germany is not a joke, nothink I want to feel by myself. I contact a lawyer and he said, this is not a game, it is real! Conclusion: The TOR node "knuffel" is down and will not come back. Please remove it from the directory. All my contact addresses and online identities related to this kind of stuff will be closed next time. I have a german website with some stuff about anonymity. It will go down in 2-3 weeks. May be, some german gay want to download and save some of my work. I will prepare an offline version of the website: http://www.anon-web.de Greetings Karsten N. _______________________________________________________________________ Jetzt neu!

<nettime> monitoring and surveillance
by Mladen Gladic 06 Jul '18

Maybe this might be of interest for the list? Thank you, Mladen Gladic Monitoring and Surveillance Inaugural Weimar-Princeton Summer School for Media Studies The first international Summer School for Media Studies, a co-operation between the Bauhaus-UniversitC$t Weimar (Internationales Kolleg fC<r Kulturtechnikforschung und Medienphilosophie, IKKM) and Princeton University (Department of German), will take place from June 6 b June 10, 2011 in Weimar, Germany. Conceived as the first in a series of annual summer schools that will be held alternately at the IKKM Weimar and at Princeton University, the 2011 program will be directed by Lorenz Engell (Weimar) and Thomas Levin (Princeton). This yearbs summer school will focus on the comparative analysis and theoretical investigation of selected aspects of surveillance culture. The weeklong series of seminars, workshops, and lectures will be devoted to an examination of the technological, aesthetic, political, and conceptual dimensions of surveillance practices. The summer school will address these practices specifically within the categories of monitoring, tracking, and data aggregation. The concept of monitoring is especially relevant to surveillance practices inherent in television technology and therefore refers to new forms of engaging with the visual. Tracking, on the other hand, refers to a wider scope of the politics of control, which are promoted, for instance, by the use of devices such as GPS and cell phone positionality services. Furthermore, these politics also underlie the emerging cultures of social media. The aggregation of vast databases of personal information gathered from, for example, frequent flyer accounts, surfing history, toll-roads, cell phone and credit card usage, all result from the ability to track information. This process of data aggregation is aimed at the production of cyber-portraiturebor the bdata shadowbbwhich exists for nearly everyone and calls into question the notion of informational self-determination within the framework of what one could call a surveillance ontology (I am surveilled therefore I am). The summer school will discuss and compare these practices of surveillance and offer in-depth analyses of both the conceptual framework and the media of surveillance.

Re: [cryptography] workaround for length extension attacks (was: Doubts over necessity of SHA-3 cryptography standard)

Honest question: why should we think they can do it? Everyone was invited to take part in the SHA-3 competition, and many international teams did. In fact, most of the finalists aren't US teams. Of all the hundreds of entrants there are 5 left. It seems that most were weeded out because they were less-that-maximally efficient or had attacks on their security. Beating SHA-2-256 or SHA-2-512/256 is turning out to be harder than anyone expected. > At the end, supremacy in setting up cryptographic > standards is what will bring reputation, trust and strategic > positioning in the world that in the following years will digest > exabytes per hour. No one spends more money on info systems than the US Government. Vendors can implement whatever they want in the own (or extensible) protocols, but if USG requires SHA-3, it's going to be implemented in gear designed for sale in N. America. Still, China is an increasing market too and their rulers are not afraid of "intelligent design". We have them to thank for killing off proprietary incompatible cellphone chargers.

Alternatively, NIST could say "we've learned so much about hash functions over the past few years that we're going to allow designers another round of submissions." - Marsh _______________________________________________ cryptography mailing list cryptography(a)randombit.net http://lists.randombit.net/mailman/listinfo/cryptography ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
