The law make it sound like it will be optional, but in a few -years there will be no option any more. The ID will be required to -vote, to get a bank account, a bank card, to change address on the -post office, to receive an electronic ID or to get a drivers license -and many other tasks required to function in Norway. The banks plan -to stop providing their own ID on the bank cards when this new -national ID is introduced, and the national road authorities plan to -change the drivers license to no longer be usable as identity cards. -In effect, to function as a citizen in Norway a national ID card will -be required, and to get it one need to provide the fingerprints to -the police.</p> - -<p>In addition to handing the fingerprint to the police (which -promised to not make a copy of the fingerprint image at that point in -time, but say nothing about doing it later), a picture of the -fingerprint will be stored on the RFID chip, along with a picture of -the face and other information about the person. Some of the -information will be encrypted, but the encryption will be the same -system as currently used in the passports.

I got curious and wondered what the same calculation would look -like today. To do so one need an idea of how much data storage is -needed for each minute of sound, how many minutes all the calls in -Norway sums up to, and the cost of data storage.</p> - -<p>The 2005 numbers are from -<a href="http://www.digi.no/analyser/2005/10/04/vi-prater-stadig-mindre-i-roret">digi.no</a>, -the 2012 numbers are from -<a href="http://www.nkom.no/aktuelt/nyheter/fortsatt-vekst-i-det-norske-ekommarkedet">a -NKOM report</a>, and I got the 2013 numbers after asking NKOM via -email. I was told the numbers for 2014 will be presented May 20th, -and decided not to wait for those, as I doubt they will be very -different from the numbers from 2013.</p> - -<p>The amount of data storage per minute sound depend on the wanted -quality, and for phone calls it is generally believed that 8 Kbit/s is -enough. See for example a -<a href="http://www.cisco.com/c/en/us/support/docs/voice/voice-quality/7934-bwidth-consume.html#topic1">summary -on voice quality from Cisco</a> for some alternatives. 8 Kbit/s is 60 -Kbytes/min, and this can be multiplied with the number of call minutes -to get the storage requirements.</p> - -<p>Storage prices varies a lot, depending on speed, backup strategies, -availability requirements etc. But a simple way to calculate can be -to use the price of a TiB-disk (around 1000 NOK / 120 EUR) and double -it to take space, power and redundancy into account. It could be much -higher with high speed and good redundancy requirements.</p> - -<p>But back to the question, What would it cost to store all phone -calls in Norway? Not much. Here is a small table showing the -estimated cost, which is within the budget constraint of most medium -and large organisations:</p> - -<table border="1"> -<tr><th>Year</th><th>Call minutes</th><th>Size</th><th>Price in NOK / EUR</th></tr> -<tr><td>2005</td><td align="right">24 000 000 000</td><td align="right">1.3 PiB</td><td align="right">3 mill / 358 000</td></tr> -<tr><td>2012</td><td align="right">18 000 000 000</td><td align="right">1.0 PiB</td><td align="right">2.2 mill / 262 000</td></tr> -<tr><td>2013</td><td align="right">17 000 000 000</td><td align="right">950 TiB</td><td align="right">2.1 mill / 250 000</td></tr> -</table> - -<p>This is the cost of buying the storage. Maintenance need to be -taken into account too, but calculating that is left as an exercise -for the reader. But it is obvious to me from those numbers that -recording the sound of all phone calls in Norway is not going to be -stopped because it is too expensive. I wonder if someone already is -collecting the data?</p> +</ul> + +<p>This assume a service following +<a href="https://tools.ietf.org/html/rfc3161">IETF RFC 3161</a> is +used, which specifiy the given MIME type for replies and the .tsr file +ending for the content of such trusted timestamp. As far as I can +tell from the Noark 5 specifications, it is OK to have several +variants/renderings of a dokument attached to a given +dokumentbeskrivelse objekt. It might be stretching it a bit to make +some of these variants represent crypto-signatures useful for +verifying the document integrity instead of representing the dokument +itself.</p> + +<p>Using the source of the service in formatDetaljer allow several +timestamping services to be used. This is useful to spread the risk +of key compromise over several organisations. It would only be a +problem to trust the timestamps if all of the organisations are +compromised.</p> + +<p>The following oneliner on Linux can be used to generate the tsr +file. $input is the path to the file to checksum, and $sha256 is the +SHA-256 checksum of the file (ie the "<sjekksum>.tsr" value mentioned +above).</p> + +<p><blockquote><pre> +openssl ts -query -data "$inputfile" -cert -sha256 -no_nonce \ + | curl -s -H "Content-Type: application/timestamp-query" \ + --data-binary "@-" http://zeitstempel.dfn.de > $sha256.tsr +</pre></blockquote></p> + +<p>To verify the timestamp, you first need to download the public key +of the trusted timestamp service, for example using this command:</p> + +<p><blockquote><pre> +wget -O ca-cert.txt \ + https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt +</pre></blockquote></p> + +<p>Note, the public key should be stored alongside the timestamps in +the archive to make sure it is also available 100 years from now. It +is probably a good idea to standardise how and were to store such +public keys, to make it easier to find for those trying to verify +documents 100 or 1000 years from now. :)</p> + +<p>The verification itself is a simple openssl command:</p> + +<p><blockquote><pre> +openssl ts -verify -data $inputfile -in $sha256.tsr \ + -CAfile ca-cert.txt -text +</pre></blockquote></p> + +<p>Is there any reason this approach would not work?

But apparently it is, and I managed to get an -interview with one of the friends of the project there, Shirish -Agarwal.</p> - -<p><strong>Who are you, and how do you spend your days?</strong></p> - -<p>My name is Shirish Agarwal. Based out of the educational and -historical city of Pune, from the western state of Maharashtra, India. -My bread comes from giving training, giving policy tips, -installations on free software to mom and pop shops in different -fields from Desktop publishing to retail shops as well as work with -few software start-ups as well.</p> - -<p><strong>How did you get in contact with the Skolelinux / Debian Edu -project?</strong></p> - -<p>It started innocently enough. I have been using Debian for a few -years and in one local minidebconf / debutsav I was asked if there was -anything for schools or education. I had worked / played with free -educational softwares such as Gcompris and Stellarium for my many -nieces and nephews so researched and found Debian Edu or Skolelinux as -it was known then. Since then I have started using the various -education meta-packages provided by the project.</p> - -<p><strong>What do you see as the advantages of Skolelinux / Debian -Edu?</strong></p> - -<p>It's closest I have seen where a package full of educational -software are packed, which are free and open (both literally and -figuratively). Even if I take the simplest software which is -gcompris, the number of activities therein are amazing. Another one of -the softwares that I have liked for a long time is stellarium. Even -pysycache is cool except for couple of issues I encountered -<a href="https://bugs.debian.org/781841">#781841</a> and -<a href="https://bugs.debian.org/781842">#781842</a>.</p> - -<p>I prefer software installed on the system over web based solutions, -as a web site can disappear any time but the software on disk has the -possibility of a larger life span. Of course with both it's more a -question if it has enough users who make it fun or sustainable or both -for the developer per-se.</p> - -<p><strong>What do you see as the disadvantages of Skolelinux / Debian -Edu?</strong></p> - -<p>I do see that the Debian Edu team seems to be short-handed and I -think more efforts should be made to make it popular and ask and take -help from people and the larger community wherever possible.</p> - -<p>I don't see any disadvantage to use Skolelinux apart from the fact -that most apps. are generic which is good or bad how you see it. -However, saying that I do acknowledge the fact that the canvas is -pretty big and there are lot of interesting ideas that could be done -but for reasons not known not done or if done I don't know about them. -Let me share some of the ideas (these are more upstream based but -still) I have had for a long time :</p> - -<p>1. Classical maths question of two trains in opposing directions -each running @x kmph/mph at y distance, when they will meet and how -far would each travel and similar questions like these. - -<p>The computer is a fantastic system where questions like these can -be drawn, animated and the methodology and answers teased out in -interactive manner. While sites such as the -<a href="http://mathforum.org/dr.math/faq/faq.two.trains.html">Ask -Dr. Math FAQ on The Two Trains problem</a> (as an example or point of -inspiration) can be used there is lot more that can be done. I dunno -if there is a free software which does something like this. The idea -being a blend of objects + animation + interaction which does -this. The whole interaction could be gamified with points or sounds or -colourful celebration whenever the user gets even part of the question -or/and methodology right. That would help reinforce good behaviour. -This understanding could be used to share/showcase everything from how -the first wheel came to be, to evolution to how astronomy started, -psychics and everything in-between.</p> - -<p>One specific idea in the train part was having the Linux mascot on -one train and the BSD or GNU mascot on the other train and they -meeting somewhere in-between. Characters from blender movies could -also be used.</p> - -<p>2. Loads of crossword-puzzles with reference to subjects: We have -enormous data sets in Wikipedia and Wikitionary. I don't think it -should be a big job to design crossword puzzles. Using categories and -sub-categories it should be doable to have Q&A single word answers -from the existing data-sets. What would make it easy or hard could be -the length of the word + existence of many or few vowels depending on -the user's input.</p> - -<p>3. Jigsaw puzzles - We already have a great software called -palapeli with number of slicers making it pretty interesting. What -needs to be done is to download large number of public domain and -copyleft images, tease and use IPTC tags to categorise them into -nature, history etc. and let it loose. This could turn to be really -huge collection of images. One source could be taken from -commons.wikimedia.org, others could be huge collection of royalty-free -stock photos. Potential is immense.</p> - -<p>Apart from this, free software suffers in two directions, we lag -both in development (of using new features per-se) and maintenance a -lot. This is more so in educational software as these applications -need to be timely and the opportunity cost of missing deadlines is -immense. If we are able to solve issues of funding for development and -maintenance of such software I don't see any big difficulties. I know -of few start-ups in and around India who would love to develop and -maintain such software if funding issues could be solved.</p> - -<p><strong>Which free software do you use daily?</strong></p> - -<p>That would be huge list. Some of the softwares are obviously apt, -aptitude, debdelta, leafpad, the shell of course (zsh nowadays), -quassel for IRC. In games I use shisen-sho while card-games are evenly -between kpat and Aiselriot. In desktops it's a tie between -gnome-flashback and mate.</p> - -<p><strong>Which strategy do you believe is the right one to use to -get schools to use free software?</strong></p> - -<p>I think it should first start with using specific FOSS apps. in -whatever environment they are. If it's MS-Windows or Mac so be it. -Once they are habitual with the apps. and there is buy-in from the -school management then it could be installed anywhere. Most of the -people now understand the concept of a repository because of the -various online stores so it isn't hard to convince on that front.</p> - -<p>What is harder is having enough people with technical skills and -passion to service them. If you get buy-in from one or two teachers -then ideas like above could also be asked to be done as a project as -well.</p> - -<p>I think where we fall short more than anything is in marketing. For -instance, Debian has this whole range of fonts in its archive but -there isn't even a page where all those different fonts in the La -Ipsum format could be tried out for newcomers.</p> - -<p>One of the issues faced constantly in installations is with updates -and upgrades. People have this myth that each update and upgrade -means the user interface will / has to change. I have seen this -innumerable times. That perhaps is one of the reasons which browsers -like Iceweasel / Firefox change user interfaces so much, not because -it might be needed or be functional but because people believe that -changed user interfaces are better. This, can easily be pointed with -the user interfaces changed with almost every MS-Windows and Mac OS -releases.</p> - -<p>The problems with Debian Edu for deployment are many. The biggest -is the huge gap between what is taught in schools and what Debian Edu -is aimed at. - -<p>Me and my friends did teach on week-ends in a government school for -around 2 years, and -<a href="https://flossexperiences.wordpress.com/2012/10/08/sharings/">gathered -some experience</a> there. Some of the things we learnt/discovered -there was :</p> - -<ol> + Offentlig elektronisk postjournal blokkerer tilgang for utvalgte webklienter + http://people.skolelinux.org/pere/blog/Offentlig_elektronisk_postjournal_blokkerer_tilgang_for_utvalgte_webklienter.html + http://people.skolelinux.org/pere/blog/Offentlig_elektronisk_postjournal_blokkerer_tilgang_for_utvalgte_webklienter.html + Thu, 20 Apr 2017 13:00:00 +0200 + <p>Jeg oppdaget i dag at <a href="https://www.oep.no/">nettstedet som +publiserer offentlige postjournaler fra statlige etater</a>, OEP, har +begynt å blokkerer enkelte typer webklienter fra å få tilgang.
