  24       <div class="date">25th October 2017</div>
  25       <div class="body"><p>Recently, I needed to automatically check the copyright status of a
  26 set of <a href="http://www.imdb.com/">The Internet Movie database
  27 (IMDB)</a> entries, to figure out which one of the movies they refer
  28 to can be freely distributed on the Internet.  This proved to be
  29 harder than it sounds.  IMDB for sure list movies without any
  30 copyright protection, where the copyright protection has expired or
  31 where the movie is lisenced using a permissive license like one from
  32 Creative Commons.  These are mixed with copyright protected movies,
  33 and there seem to be no way to separate these classes of movies using
  34 the information in IMDB.</p>
  35
  36 <p>First I tried to look up entries manually in IMDB,
  37 <a href="https://www.wikipedia.org/">Wikipedia</a> and
  38 <a href="https://www.archive.org/">The Internet Archive</a>, to get a
  39 feel how to do this.  It is hard to know for sure using these sources,
  40 but it should be possible to be reasonable confident a movie is "out
  41 of copyright" with a few hours work per movie.  As I needed to check
  42 almost 20,000 entries, this approach was not sustainable.  I simply
  43 can not work around the clock for about 6 years to check this data
  44 set.</p>
  45
  46 <p>I asked the people behind The Internet Archive if they could
  47 introduce a new metadata field in their metadata XML for IMDB ID, but
  48 was told that they leave it completely to the uploaders to update the
  49 metadata.  Some of the metadata entries had IMDB links in the
  50 description, but I found no way to download all metadata files in bulk
  51 to locate those ones and put that approach aside.</p>
  52
  53 <p>In the process I noticed several Wikipedia articles about movies
  54 had links to both IMDB and The Internet Archive, and it occured to me
  55 that I could use the Wikipedia RDF data set to locate entries with
  56 both, to at least get a lower bound on the number of movies on The
  57 Internet Archive with a IMDB ID.  This is useful based on the
  58 assumption that movies distributed by The Internet Archive can be
  59 legally distributed on the Internet.  With some help from the RDF
  60 community (thank you DanC), I was able to come up with this query to
  61 pass to <a href="https://query.wikidata.org/">the SPARQL interface on
  62 Wikidata</a>:
  63
  64 <p><pre>
  65 SELECT ?work ?imdb ?ia ?when ?label
  66 WHERE
  67 {
  68   ?work wdt:P31/wdt:P279* wd:Q11424.
  69   ?work wdt:P345 ?imdb.
  70   ?work wdt:P724 ?ia.
  71   OPTIONAL {
  72         ?work wdt:P577 ?when.
  73         ?work rdfs:label ?label.
  74         FILTER(LANG(?label) = "en").
  75   }
  76 }
  77 </pre></p>
  78
  79 <p>If I understand the query right, for every film entry anywhere in
  80 Wikpedia, it will return the IMDB ID and The Internet Archive ID, and
  81 when the movie was released and its English title, if either or both
  82 of the latter two are available.  At the moment the result set contain
  83 2338 entries.  Of course, it depend on volunteers including both
  84 correct IMDB and The Internet Archive IDs in the wikipedia articles
  85 for the movie.  It should be noted that the result will include
  86 duplicates if the movie have entries in several languages.  There are
  87 some bogus entries, either because The Internet Archive ID contain a
  88 typo or because the movie is not available from The Internet Archive.
  89 I did not verify the IMDB IDs, as I am unsure how to do that
  90 automatically.</p>
  91
  92 <p>I wrote a small python script to extract the data set from Wikidata
  93 and check if the XML metadata for the movie is available from The
  94 Internet Archive, and after around 1.5 hour it produced a list of 2097
  95 free movies and their IMDB ID.  In total, 171 entries in Wikidata lack
  96 the refered Internet Archive entry.  I assume the 60 "disappearing"
  97 entries (ie 2338-2097-171) are duplicate entries.</p>
  98
  99 <p>This is not too bad, given that The Internet Archive report to
 100 contain <a href="https://archive.org/details/feature_films">5331
 101 feature films</a> at the moment, but it also mean more than 3000
 102 movies are missing on Wikipedia or are missing the pair of references
 103 on Wikipedia.</p>
 104
 105 <p>I was curious about the distribution by release year, and made a
 106 little graph to show how the amount of free movies is spread over the
 107 years:<p>
 108
 109 <p><img src="http://people.skolelinux.org/pere/blog/images/2017-10-25-verk-i-det-fri-filmer.png"></p>
 110
 111 <p>I expect the relative distribution of the remaining 3000 movies to
 112 be similar.</p>
 113
 114 <p>If you want to help, and want to ensure Wikipedia can be used to
 115 cross reference The Internet Archive and The Internet Movie Database,
 116 please make sure entries like this are listed under the "External
 117 links" heading on the Wikipedia article for the movie:</p>
 118
 119 <p><pre>
 120 * {{Internet Archive film|id=FightingLady}}
 121 * {{IMDb title|id=0036823|title=The Fighting Lady}}
 122 </pre></p>
 123
 124 <p>Please verify the links on the final page, to make sure you did not
 125 introduce a typo.</p>

 340       <div class="date"> 9th October 2017</div>
 341       <div class="body"><p>At my nearby maker space,
 342 <a href="http://sonen.ifi.uio.no/">Sonen</a>, I heard the story that it
 343 was easier to generate gcode files for theyr 3D printers (Ultimake 2+)
 344 on Windows and MacOS X than Linux, because the software involved had
 345 to be manually compiled and set up on Linux while premade packages
 346 worked out of the box on Windows and MacOS X.  I found this annoying,
 347 as the software involved,
 348 <a href="https://github.com/Ultimaker/Cura">Cura</a>, is free software
 349 and should be trivial to get up and running on Linux if someone took
 350 the time to package it for the relevant distributions.  I even found
 351 <a href="https://bugs.debian.org/706656">a request for adding into
 352 Debian</a> from 2013, which had seem some activity over the years but
 353 never resulted in the software showing up in Debian.  So a few days
 354 ago I offered my help to try to improve the situation.</p>
 355
 356 <p>Now I am very happy to see that all the packages required by a
 357 working Cura in Debian are uploaded into Debian and waiting in the NEW
 358 queue for the ftpmasters to have a look.  You can track the progress
 359 on
 360 <a href="https://qa.debian.org/developer.php?email=3dprinter-general%40lists.alioth.debian.org">the
 361 status page for the 3D printer team</a>.</p>
 362
 363 <p>The uploaded packages are a bit behind upstream, and was uploaded
 364 now to get slots in <a href="https://ftp-master.debian.org/new.html">the NEW
 365 queue</a> while we work up updating the packages to the latest
 366 upstream version.</p>
 367
 368 <p>On a related note, two competitors for Cura, which I found harder
 369 to use and was unable to configure correctly for Ultimaker 2+ in the
 370 short time I spent on it, are already in Debian.  If you are looking
 371 for 3D printer "slicers" and want something already available in
 372 Debian, check out
 373 <a href="https://tracker.debian.org/pkg/slic3r">slic3r</a> and
 374 <a href="https://tracker.debian.org/pkg/slic3r-prusa">slic3r-prusa</a>.
 375 The latter is a fork of the former.</p>

 402 så langt har jeg fått alt jeg har lett etter.  De har i tillegg det

 420       <div class="date">29th September 2017</div>
 421       <div class="body"><p>Every mobile phone announce its existence over radio to the nearby
 422 mobile cell towers.  And this radio chatter is available for anyone
 423 with a radio receiver capable of receiving them.  Details about the
 424 mobile phones with very good accuracy is of course collected by the
 425 phone companies, but this is not the topic of this blog post.  The
 426 mobile phone radio chatter make it possible to figure out when a cell
 427 phone is nearby, as it include the SIM card ID (IMSI).  By paying
 428 attention over time, one can see when a phone arrive and when it leave
 429 an area.  I believe it would be nice to make this information more
 430 available to the general public, to make more people aware of how
 431 their phones are announcing their whereabouts to anyone that care to
 432 listen.</p>
 433
 434 <p>I am very happy to report that we managed to get something
 435 visualizing this information up and running for
 436 <a href="http://norwaymakers.org/osf17">Oslo Skaperfestival 2017</a>
 437 (Oslo Makers Festival) taking place today and tomorrow at Deichmanske
 438 library.  The solution is based on the
 439 <a href="http://people.skolelinux.org/pere/blog/Easier_recipe_to_observe_the_cell_phones_around_you.html">simple
 440 recipe for listening to GSM chatter</a> I posted a few days ago, and
 441 will show up at the stand of <a href="http://sonen.ifi.uio.no/">Åpen
 442 Sone from the Computer Science department of the University of
 443 Oslo</a>.  The presentation will show the nearby mobile phones (aka
 444 IMSIs) as dots in a web browser graph, with lines to the dot
 445 representing mobile base station it is talking to. It was working in
 446 the lab yesterday, and was moved into place this morning.</p>
 447
 448 <p>We set up a fairly powerful desktop machine using Debian
 449 Buster/Testing with several (five, I believe) RTL2838 DVB-T receivers
 450 connected and visualize the visible cell phone towers using an
 451 <a href="https://github.com/marlow925/hopglass">English version of
 452 Hopglass</a>.  A fairly powerfull machine is needed as the
 453 grgsm_livemon_headless processes from
 454 <a href="https://tracker.debian.org/pkg/gr-gsm">gr-gsm</a> converting
 455 the radio signal to data packages is quite CPU intensive.</p>
 456
 457 <p>The frequencies to listen to, are identified using a slightly
 458 patched scan-and-livemon (to set the --args values for each receiver),
 459 and the Hopglass data is generated using the
 460 <a href="https://github.com/petterreinholdtsen/IMSI-catcher/tree/meshviewer-output">patches
 461 in my meshviewer-output branch</a>.  For some reason we could not get
 462 more than four SDRs working.  There is also a geographical map trying
 463 to show the location of the base stations, but I believe their
 464 coordinates are hardcoded to some random location in Germany, I
 465 believe.  The code should be replaced with code to look up location in
 466 a text file, a sqlite database or one of the online databases
 467 mentioned in
 468 <a href="https://github.com/Oros42/IMSI-catcher/issues/14">the github
 469 issue for the topic</a>.

 471 <p>If this sound interesting, visit the stand at the festival!</p>

 485       <div class="date">24th September 2017</div>
 486       <div class="body"><p>A little more than a month ago I wrote
 487 <a href="http://people.skolelinux.org/pere/blog/Simpler_recipe_on_how_to_make_a_simple__7_IMSI_Catcher_using_Debian.html">how
 488 to observe the SIM card ID (aka IMSI number) of mobile phones talking
 489 to nearby mobile phone base stations using Debian GNU/Linux and a
 490 cheap USB software defined radio</a>, and thus being able to pinpoint
 491 the location of people and equipment (like cars and trains) with an
 492 accuracy of a few kilometer.  Since then we have worked to make the
 493 procedure even simpler, and it is now possible to do this without any
 494 manual frequency tuning and without building your own packages.</p>
 495
 496 <p>The <a href="https://tracker.debian.org/pkg/gr-gsm">gr-gsm</a>
 497 package is now included in Debian testing and unstable, and the
 498 IMSI-catcher code no longer require root access to fetch and decode
 499 the GSM data collected using gr-gsm.</p>
 500
 501 <p>Here is an updated recipe, using packages built by Debian and a git
 502 clone of two python scripts:</p>
 503
 504 <ol>
 505
 506 <li>Start with a Debian machine running the Buster version (aka
 507   testing).</li>
 508
 509 <li>Run '<tt>apt install gr-gsm python-numpy python-scipy
 510   python-scapy</tt>' as root to install required packages.</li>
 511
 512 <li>Fetch the code decoding GSM packages using '<tt>git clone
 513   github.com/Oros42/IMSI-catcher.git</tt>'.</li>
 514
 515 <li>Insert USB software defined radio supported by GNU Radio.</li>
 516
 517 <li>Enter the IMSI-catcher directory and run '<tt>python
 518   scan-and-livemon</tt>' to locate the frequency of nearby base
 519   stations and start listening for GSM packages on one of them.</li>
 520
 521 <li>Enter the IMSI-catcher directory and run '<tt>python
 522   simple_IMSI-catcher.py</tt>' to display the collected information.</li>
 523
 524 </ol>
 525
 526 <p>Note, due to a bug somewhere the scan-and-livemon program (actually
 527 <a href="https://github.com/ptrkrysik/gr-gsm/issues/336">its underlying
 528 program grgsm_scanner</a>) do not work with the HackRF radio.  It does
 529 work with RTL 8232 and other similar USB radio receivers you can get
 530 very cheaply
 531 (<a href="https://www.ebay.com/sch/items/?_nkw=rtl+2832">for example
 532 from ebay</a>), so for now the solution is to scan using the RTL radio
 533 and only use HackRF for fetching GSM data.</p>
 534
 535 <p>As far as I can tell, a cell phone only show up on one of the
 536 frequencies at the time, so if you are going to track and count every
 537 cell phone around you, you need to listen to all the frequencies used.
 538 To listen to several frequencies, use the --numrecv argument to
 539 scan-and-livemon to use several receivers.  Further, I am not sure if
 540 phones using 3G or 4G will show as talking GSM to base stations, so
 541 this approach might not see all phones around you.  I typically see
 542 0-400 IMSI numbers an hour when looking around where I live.</p>
 543
 544 <p>I've tried to run the scanner on a
 545 <a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi 2 and 3
 546 running Debian Buster</a>, but the grgsm_livemon_headless process seem
 547 to be too CPU intensive to keep up.  When GNU Radio print 'O' to
 548 stdout, I am told there it is caused by a buffer overflow between the
 549 radio and GNU Radio, caused by the program being unable to read the
 550 GSM data fast enough.  If you see a stream of 'O's from the terminal
 551 where you started scan-and-livemon, you need a give the process more
 552 CPU power.  Perhaps someone are able to optimize the code to a point
 553 where it become possible to set up RPi3 based GSM sniffers?  I tried
 554 using Raspbian instead of Debian, but there seem to be something wrong
 555 with GNU Radio on raspbian, causing glibc to abort().</p>

 570       <div class="body"><p>For noen dager siden publiserte Jon Wessel-Aas en bloggpost om
 571 «<a href="http://www.uhuru.biz/?p=1821">Konklusjonen om datalagring som
 572 EU-kommisjonen ikke ville at vi skulle få se</a>».  Det er en
 573 interessant gjennomgang av EU-domstolens syn på snurpenotovervåkning
 574 av befolkningen, som er klar på at det er i strid med
 575 EU-lovgivingen.</p>
 576
 577 <p>Valgkampen går for fullt i Norge, og om noen få dager er siste
 578 frist for å avgi stemme.  En ting er sikkert, Høyre og Arbeiderpartiet
 579 får ikke min stemme
 580 <a href="http://people.skolelinux.org/pere/blog/Datalagringsdirektivet_gj_r_at_Oslo_H_yre_og_Arbeiderparti_ikke_f_r_min_stemme_i__r.html">denne
 581 gangen heller</a>.  Jeg har ikke glemt at de tvang igjennom loven som
 582 skulle pålegge alle data- og teletjenesteleverandører å overvåke alle
 583 sine kunder.  En lov som er vedtatt, og aldri opphevet igjen.</p>
 584
 585 <p>Det er tydelig fra diskusjonen rundt grenseløs digital overvåkning
 586 (eller "Digital Grenseforsvar" som det kalles i Orvellisk nytale) at
 587 hverken Høyre og Arbeiderpartiet har noen prinsipielle sperrer mot å
 588 overvåke hele befolkningen, og diskusjonen så langt tyder på at flere
 589 av de andre partiene heller ikke har det. Mange av
 590 <a href="https://data.holderdeord.no/votes/1301946411e">de som stemte
 591 for Datalagringsdirektivet i Stortinget</a> (64 fra Arbeiderpartiet,
 592 25 fra Høyre) er fortsatt aktive og argumenterer fortsatt for å radere
 593 vekk mer av innbyggernes privatsfære.</p>
 594
 595 <p>Når myndighetene demonstrerer sin mistillit til folket, tror jeg
 596 folket selv bør legge litt innsats i å verne sitt privatliv, ved å ta
 597 i bruk ende-til-ende-kryptert kommunikasjon med sine kjente og kjære,
 598 og begrense hvor mye privat informasjon som deles med uvedkommende.
 599 Det er jo ingenting som tyder på at myndighetene kommer til å være vår
 600 privatsfære.
 601 <a href="http://people.skolelinux.org/pere/blog/How_to_talk_with_your_loved_ones_in_private.html">Det
 602 er mange muligheter</a>.  Selv har jeg litt sans for

 624       <div class="date"> 9th August 2017</div>
 625       <div class="body"><p>On friday, I came across an interesting article in the Norwegian
 626 web based ICT news magazine digi.no on
 627 <a href="https://www.digi.no/artikler/sikkerhetsforsker-lagde-enkel-imsi-catcher-for-60-kroner-na-kan-mobiler-kartlegges-av-alle/398588">how
 628 to collect the IMSI numbers of nearby cell phones</a> using the cheap
 629 DVB-T software defined radios.  The article refered to instructions
 630 and <a href="https://www.youtube.com/watch?v=UjwgNd_as30">a recipe by
 631 Keld Norman on Youtube on how to make a simple $7 IMSI Catcher</a>, and I decided to test them out.</p>
 632
 633 <p>The instructions said to use Ubuntu, install pip using apt (to
 634 bypass apt), use pip to install pybombs (to bypass both apt and pip),
 635 and the ask pybombs to fetch and build everything you need from
 636 scratch.  I wanted to see if I could do the same on the most recent
 637 Debian packages, but this did not work because pybombs tried to build
 638 stuff that no longer build with the most recent openssl library or
 639 some other version skew problem.  While trying to get this recipe
 640 working, I learned that the apt->pip->pybombs route was a long detour,
 641 and the only piece of software dependency missing in Debian was the
 642 gr-gsm package.  I also found out that the lead upstream developer of
 643 gr-gsm (the name stand for GNU Radio GSM) project already had a set of
 644 Debian packages provided in an Ubuntu PPA repository.  All I needed to
 645 do was to dget the Debian source package and built it.</p>
 646
 647 <p>The IMSI collector is a python script listening for packages on the
 648 loopback network device and printing to the terminal some specific GSM
 649 packages with IMSI numbers in them.  The code is fairly short and easy
 650 to understand.  The reason this work is because gr-gsm include a tool
 651 to read GSM data from a software defined radio like a DVB-T USB stick
 652 and other software defined radios, decode them and inject them into a
 653 network device on your Linux machine (using the loopback device by
 654 default).  This proved to work just fine, and I've been testing the
 655 collector for a few days now.</p>
 656
 657 <p>The updated and simpler recipe is thus to</p>
 658
 659 <ol>
 660
 661 <li>start with a Debian machine running Stretch or newer,</li>
 662
 663 <li>build and install the gr-gsm package available from
 664 <a href="http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/">http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/</a>,</li>
 665
 666 <li>clone the git repostory from <a href="https://github.com/Oros42/IMSI-catcher">https://github.com/Oros42/IMSI-catcher</a>,</li>
 667
 668 <li>run grgsm_livemon and adjust the frequency until the terminal
 669 where it was started is filled with a stream of text (meaning you
 670 found a GSM station).</li>
 671
 672 <li>go into the IMSI-catcher directory and run 'sudo python simple_IMSI-catcher.py' to extract the IMSI numbers.</li>
 673
 674 </ol>
 675
 676 <p>To make it even easier in the future to get this sniffer up and
 677 running, I decided to package
 678 <a href="https://github.com/ptrkrysik/gr-gsm/">the gr-gsm project</a>
 679 for Debian (<a href="https://bugs.debian.org/871055">WNPP
 680 #871055</a>), and the package was uploaded into the NEW queue today.
 681 Luckily the gnuradio maintainer has promised to help me, as I do not
 682 know much about gnuradio stuff yet.</p>
 683
 684 <p>I doubt this "IMSI cacher" is anywhere near as powerfull as
 685 commercial tools like
 686 <a href="https://www.thespyphone.com/portable-imsi-imei-catcher/">The
 687 Spy Phone Portable IMSI / IMEI Catcher</a> or the
 688 <a href="https://en.wikipedia.org/wiki/Stingray_phone_tracker">Harris
 689 Stingray</a>, but I hope the existance of cheap alternatives can make
 690 more people realise how their whereabouts when carrying a cell phone
 691 is easily tracked.  Seeing the data flow on the screen, realizing that
 692 I live close to a police station and knowing that the police is also
 693 wearing cell phones, I wonder how hard it would be for criminals to
 694 track the position of the police officers to discover when there are
 695 police near by, or for foreign military forces to track the location
 696 of the Norwegian military forces, or for anyone to track the location
 697 of government officials...</p>
 698
 699 <p>It is worth noting that the data reported by the IMSI-catcher
 700 script mentioned above is only a fraction of the data broadcasted on
 701 the GSM network.  It will only collect one frequency at the time,
 702 while a typical phone will be using several frequencies, and not all
 703 phones will be using the frequencies tracked by the grgsm_livemod
 704 program.  Also, there is a lot of radio chatter being ignored by the
 705 simple_IMSI-catcher script, which would be collected by extending the
 706 parser code.  I wonder if gr-gsm can be set up to listen to more than
 707 one frequency?</p>

 759       <div class="date">27th June 2017</div>
 760       <div class="body"><p>Jeg kom over teksten
 761 «<a href="https://freedom-to-tinker.com/2017/06/21/killing-car-privacy-by-federal-mandate/">Killing
 762 car privacy by federal mandate</a>» av Leonid Reyzin på Freedom to
 763 Tinker i dag, og det gleder meg å se en god gjennomgang om hvorfor det
 764 er et urimelig inngrep i privatsfæren å la alle biler kringkaste sin
 765 posisjon og bevegelse via radio.  Det omtalte forslaget basert på
 766 Dedicated Short Range Communication (DSRC) kalles Basic Safety Message
 767 (BSM) i USA og Cooperative Awareness Message (CAM) i Europa, og det
 768 norske Vegvesenet er en av de som ser ut til å kunne tenke seg å
 769 pålegge alle biler å fjerne nok en bit av innbyggernes privatsfære.
 770 Anbefaler alle å lese det som står der.
 771
 772 <p>Mens jeg tittet litt på DSRC på biler i Norge kom jeg over et sitat
 773 jeg synes er illustrativt for hvordan det offentlige Norge håndterer
 774 problemstillinger rundt innbyggernes privatsfære i SINTEF-rapporten
 775 «<a href="https://www.sintef.no/publikasjoner/publikasjon/Download/?pubid=SINTEF+A23933">Informasjonssikkerhet
 776 i AutoPASS-brikker</a>» av Trond Foss:</p>
 777
 778 <p><blockquote>
 779 «Rapporten ser ikke på informasjonssikkerhet knyttet til personlig
 780   integritet.»
 781 </blockquote></p>
 782
 783 <p>Så enkelt kan det tydeligvis gjøres når en vurderer
 784 informasjonssikkerheten.  Det holder vel at folkene på toppen kan si
 785 at «Personvernet er ivaretatt», som jo er den populære intetsigende
 786 frasen som gjør at mange tror enkeltindividers integritet tas vare på.
 787 Sitatet fikk meg til å undres på hvor ofte samme tilnærming, å bare se
 788 bort fra behovet for personlig itegritet, blir valgt når en velger å
 789 legge til rette for nok et inngrep i privatsfæren til personer i
 790 Norge.  Det er jo sjelden det får reaksjoner.  Historien om
 791 reaksjonene på Helse Sør-Østs tjenesteutsetting er jo sørgelig nok et
 792 unntak og toppen av isfjellet, desverre.  Tror jeg fortsatt takker nei
 793 til både AutoPASS og holder meg så langt unna det norske helsevesenet
 794 som jeg kan, inntil de har demonstrert og dokumentert at de verdsetter
 795 individets privatsfære og personlige integritet høyere enn kortsiktig
 796 gevist og samfunnsnytte.</p>
