Q&A: The science of online censorship

first_imgQ: So how did you get into the science of censorship?A: After my Ph.D. in computer science at the University of Toronto [in Canada], I did a postdoc at the same place. I walked into the political science department and discovered the “Citizen Lab.” They were studying internet censorship, and I realized that the problems had a lot to do with network protocols, which I study.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)Q: Those protocols are the rules that internet servers follow to pass information along. But how do you detect that censors are exploiting them?A: That’s my main project now. It’s a software platform called ICLab—for Information Controls Lab. We’ve put it onto the [tiny, cheap computer known as the] Raspberry Pi. Citizen Lab has people on the ground around the world—Iran, Turkey, Yemen—and they plug [the computer] into their networks. ICLab does web requests [to see whether sites are blocked or redirected] … and it also captures data packets and looks at their headers  to see if anything is getting injected. [The header includes the instructions for where the data should go.] Then, all that information comes back to us over the internet. We have 14 Raspberry Pis up and online.Q: Finding any surprises so far?A: We did find that the Iranian government is censoring some [political] websites. But some of the censorship is from companies. In Iran the filtering [of websites is happening] on servers in the U.S. that are restricting access, possibly due to sanctions. … A lot of the research [on censorship] so far has focused on the usual suspects in the Middle East. But U.S. companies are filtering [based on people’s geographic location], too.Q: When will you reveal the results from your censorship detectors?A: Next year? I’m recruiting a new student to do some of the data analysis work.Q: Is some censorship ethical?A: Most people agree that something like child pornography should be blocked. But there needs to be transparency in censorship. Internet users should know what is being blocked and be able to decide if that’s OK or not. Information doesn’t flow through the internet as freely as it seems. Depending on which country you live in, you may see different content on a web page—or no content at all. As the internet has become the most important public space for everything from protest movements to pornography, governments around the world have started locking it down. And that has given rise to a new field of research: the science of censorship. ScienceInsider caught up with Phillipa Gill, a computer scientist at the University of Massachusetts in Amherst, to find out what’s cooking in this online cat and mouse game. She spoke to us yesterday from the Internet Measurement Conference in Santa Monica, California, which she co-chaired. This interview has been edited for brevity and clarity.last_img read more

NASA moon orbiter spots Change 4 lander in a crater

first_img Chang’e 4 explores the moon Chang’e 4 is pointed to by small white arrows near the lower right-hand side of this LRO image. NASA/GSFC/Arizona State University You’ll need to squint to spot it, but NASA’s Lunar Reconnaissance Orbiter managed to capture a look at the Chinese National Space Agency’s (CNSA) Chang’e 4 lander hanging out on the far side of the moon. Chang’e 4 touched down on Jan. 3 in the Von Kármán crater. LRO took the image on Jan. 30. “As LRO approached the crater from the east, it rolled 70° to the west to snap this spectacular view looking across the floor towards the west wall,” writes Mark Robinson for Arizona State University’s LRO Camera site.The lander, which is about the size of a car, appears as a tiny bright spot. Chang’e 4 released its Jade Rabbit 2 lunar rover in early January, but the small machine is not visible in the LRO image.lrochangecloseup1Here’s a closer look at the bright spot that is the Chang’e 4 lander.  NASA/GSFC/Arizona State University NASA announced in mid-January it had discussed observing Chang’e 4’s landing plume with CNSA in order to learn more about how dust is kicked up during a spacecraft landing. China’s lander is the first spacecraft to land on the far side of the moon, sometimes called the dark side even though it gets plenty of sunlight. The lander and rover are both powered by solar panels.  NASA Space Chang’e 4 is on a mission to learn more about this mysterious region of the moon. It also hosted a short-lived attempt to sprout plants within a container. China already has its eyes set on another moon mission in 2019, but this time it plans to bring back lunar samples. If successful, those lunar bits will be the first brought back to Earth in decades.
