Claims (14)

1. Tagskriver (30) for en programmerbar tag (60), hvor tagskriveren (30) er indrettet til at generere en sikkerhedsidentifikator (60') under skrivning af data til tag'en, hvilken sikkerhedsidentifikator (60') er afhængig af én eller flere af de data, som skrives, data som allerede foreligger på tag'en, metadata knyttet til dataene, tag'en og/eller skrivningen af dataene, kendetegnet ved, at tagskriveren (30) er indrettet til at skrive sikkerhedsidentifikatoren til et fjerndatalager (40), idet sikkerhedsidentifikatoren (60') kan gendannes ud fra data i tag'en for fremtidig authentifikation af tag'en imod sikkerhedsidentifikatoren (60') i fjerndatalageret (40), hvilken sikkerhedsidentifikator yderligere er ikke gendannelig efter ændring af forudbestemte dele af data i tag'en.
2. Tagskriver (30) ifølge krav 1, hvor sikkerhedsidentifikatoren (60') er en udvalgt enkelt af en kontrolsum, en hash eller en krypteret digest.
3. Tagskriver (30) ifølge krav 1 eller 2, hvor sikkerhedsidentifikatoren (60') er afledt af sikkerhedsstatusdata som er indeholdt i tag'en og/eller indhold i et brugerhukommelsesområde i tag'en.
4. Tagskriver (30) ifølge ethvert af de foregående krav, hvor i det mindste en del af sikkerhedsidentifikatoren (60') er skrevet integreret til dataene på tag'en, hvor omprogrammering af tag'en ændrer eller sletter sikkerhedsidentifikatoren.
5. Tagskriver (30) ifølge krav 3 eller 4, hvor tag'en omfatter en unik identifikator, idet tagskriveren (30) er indrettet til at forbinde sikkerhedsidentifikatoren med den unikke identifikator i fjernlageret (40).
6. Tagskriver (30) ifølge krav 5, hvor den unikke identifikator er fysisk skrevet på én eller flere af tag'en og dennes indpakning og opnås fra tag'en og/eller indpakningen for skrivning af sikkerhedsidentifikatoren (60') til fjernlageret.
7. Tagskriver (30) ifølge ethvert af de foregående krav, hvor tagskriveren (30) yderligere er indrettet til at skrive data på tag'en, ud fra hvilke sikkerhedsidentifikatoren (60') afledes, til et back-up-datalager.
8. Tagskriver ifølge ethvert af de foregående krav, hvor tagskriveren (30) er indrettet til at anvende et delsæt af data på tag'en til at generere sikkerhedsidentifikatoren (60').
9. Tagskriver ifølge krav 8, hvor et mønster til at bestemme delsættet er indkodet for tag'en i et fjerndatalager, idet tagskriveren er indrettet til at genfinde mønsteret og anvende dette til at bestemme delsættet.
10. Tagskriver ifølge ethvert af de foregående krav, hvor tag'en er en RFID-tag.
11. Taglæser (20), kendetegnet ved, at taglæseren er indrettet til at læse data fra en hukommelse i en programmerbar tag (60) og generere en sikkerhedsidentifikator ud fra de læste data, idet taglæseren er indrettet til at sammenligne sikkerhedsidentifikatoren med en på forhånd beregnet sikkerhedsidentifikator for tag'en for at authentificere dataene i hukommelsen, hvilken på forhånd beregnet sikkerhedsidentifikator er lagret i et datalager (40) fjernt fra tag'en, hvor sikkerhedsidentifikatoren og den tidligere lagrede sikkerhedsidentifikator genereres ud fra data i tag'en, ved ændring af forudbestemte dele af data i tag'en genereres en anden sikkerhedsidentifikator, for derved at forårsage fejlende authentifikation.
12. Taglæser (20) ifølge krav 11, hvor tag'en har en unik identifikator, taglæseren er indrettet til at anvende den unikke identifikator til at genfinde den tidligere beregnede sikkerhedsidentifikator fra et fjerndatalager.
13. Taglæser (20) ifølge krav 12, hvor den unikke identifikator er fysisk skrevet på tag'en eller dennes indpakning, idet læseren omfatter en brugerinterface til at modtage den unikke identifikator.
14. Fremgangsmåde til skrivning til en programerbar tag, kendetegnet ved: generering af en sikkerhedsidentifikator under skrivning af data til tag'en, hvilken sikkerhedsidentifikator er afhængig af én eller flere af de data, som skrives, data allerede foreliggende på tag'en, metadata knyttet til dataene, tag'en og/eller skrivningen af dataene; lagring af sikkerhedsidentifikatoren i et fjerndatalager for fremtidig authentifikation af tag'en og sikkerhedsidentifikatoren; og gendannelse af sikkerhedsidentifikatoren ud fra data på tag'en og sammenligning af den gendannede sikkerhedsidentifikator med den lagrede sikkerhedsidentifikator i fjerndatalageretforauthentifikation af tag'en, hvor sikkerhedsidentifikatoren er ikke gendannelig efter ændring af forudbestemte dele af dataene i tag'en.
