  24       <div class="date">16th January 2011</div>
  25       <div class="body"><p>Bruken av RFID brer om seg.  Klær, matvarer, borgere, elever,
  26 studenter og ansatte blir radiomerket på en måte som gjør det enkelt å
  27 følge med på hvor de beveger seg.
  28 <a href="http://www.wired.com/science/discoveries/news/2003/10/60898">Historien
  29 fra Enterprise Charter School</A> i Buffalo, New York beskriver
  30 drømmen om massiv overvåkning av bevegelsesmønsteret til elevene
  31 vha. RFID.  For de fleste får jeg inntrykk av at overgangen virker
  32 ganske liten, da de allerede er radiomerket med GSM-telefoner som
  33 rapporterer hvor de er til enhver tid.  Personlig ser jeg på retten
  34 til å ferdes anonymt og uten å bli overvåket som fundamental for å
  35 beholde et demokratisk og fritt samfunn, og tror denne retten kun
  36 overlever hvis den blir brukt av borgerne, og velger derfor å ikke gå
  37 rundt med radiopeilesender på meg.</p>
  38
  39 <p>RFID-merking av folk, det være seg med busskort fra Ruter, student-
  40 og ansattkort for Universitetet i Oslo, nyere pass eller i klær som
  41 folk går med er radiomerking av befolkningen.</p>
  42
  43 <p>For å kunne sette meg inn i RFID-teknologi ser jeg etter en norsk
  44 leverandør som kan selge meg en RFID leser/skriver med USB-tilkobling
  45 som kan brukes til å se hva som er RFID-merket i dag.  Jeg er fortalt
  46 at Ruter sitt
  47 <a href="http://www.kollektivanbud.no/dokumenter/20100928%20Travelcard%20Production%20Specification%20_2_.pdf">Flexus-kort</a>
  48 bruker 13,56 MHz som kan leses og skrives til, mens andre dinger
  49 typisk bruker 125 kHz som i utgangspunktet kun kan leses fra.  Det
  50 finnes også andre frekvenser i bruk.  Vet ikke hva som finnes av
  51 rimelig utstyr for lesing og skriving, men ble tipset om at
  52 <a href="http://www.robonor.no/mag/default/rfid-2.html">Robonor</a> har
  53 endel slike deler.  Programvare på Linux for å lese og skrive mot RFID
  54 er tilgjengelig fra blant andre <a href="http://www.openpcd.org/">Open
  55 Proximity Coupling Devices</a>-prosjektet og
  56 <a href="http://www.rfdump.org/">RFDump</a>-prosjektet.</p>
  57
  58 <p>Blokkering av RFID-signaler ser ut til å være mulig ved å plassere
  59 kort med RFID i en metallboks.  Min kortmappe med metall-plate for å
  60 stive av, lot i hvert fall til å blokkere for Ruters avlesning av
  61 Flexus-kort.  Er også blitt fortalt at det fungerer å bruke en liten
  62 metall-boks.  Er ikke sikker på om dette også blokkerer for mer
  63 følsomme lesere som kan lese av RFID-signaler på mange meters
  64 avstand.</p>
  65
  66 <p>De nye norske biometriske passene kan enkelt leses av på avstand og
  67 kopieres med RFID, slik at de som ønsker det kan å se bilde av
  68 nordmenn i nærheten, og informasjon om fingeravtrykk, høyde, hårfarge
  69 og det meste av informasjon om innehaveren.  For meg virker det som en
  70 massiv sikkerhetsrisko, og det er meg et komplett mysterium at
  71 Stortinget og regjeringen har gått med på RFID-merking av pass.
  72 <a href="http://en.wikipedia.org/wiki/Biometric_passport">wikipedia har
  73 mer</a> om de nye biometriske passene.</p>
