Outguess 0.25/4/2023 The median anonymity set size was 2, meaning that half of the combinations of town date of birth gender in our data set either unambiguously identified an individual (Dutch citizen), or a group of only 2 individuals. We also included this one (tables 2 and 3 in the paper): Guido van ‘t Noordende, Cees de Laat and I studied registry office (GBA) data of 2.7 million Dutch citizens (~16% of the total population) to explore their identifiability by various quasi-identifiers consisting of partial or full postal code, partial or full date of birth and gender. UPDATE : I suddenly realize that A Study on the Re-Identifiability of Dutch Citizens (.pdf) presented at HotPETS 2010 is relevant here. Disclosing SSN, bank account numbers, credit card numbers and DigiD credentials probably remains a bad idea. In a sense, our representatives function as guinea pigs for testing assumptions about the risk associated with disclosing personal data - or rather, at least with disclosing this particular personal data. more information is needed (SSN, bank account number), or multifactor authentication requires possession of token …because this personal info is, by itself, insufficient to compromise accounts?.…because this personal info was not used as password or answer to a security question?.you know they are customer/employee/student at X but you don’t know their username for logging in to X …because their personal logins/names are unknown?. ![]() you don’t know they use Gmail, which bank, insurance, webshops. …because their personal subscriptions/service-usage is unknown?.…because this particular knowledge does not pose a threat?.With personal data being readily available, these high-profile targets surely must have already been victim (although maybe not be aware of it) of password-guessing and social engineering attacks?.I hope these public figures don’t use that information as password or answer to security question in their private life.When stumbling upon that file, the following thoughts came to mind: (past) affiliations w/foundations, associations.Some of the personal information it contains (not all values are present for all representatives): The Dutch House of Representatives provides information about all 150 representatives in a single XML file: ( mirror of today’s copy also in Google-cache, but not ). ![]() Politicians are public figures and therefore have reduced reasonable expectations of privacy. cgi-bin/pdcsns.cgi?user=&dir=/9202000/g/&filename=/9202000/t5.sns&via=direct&v01=25910Ĭ:Documents and Settingsu0072s1Local SettingsTemporary Internet Filesu0072s1Local Settingsu00a110Local SettingsLocal Settingsu00g5m0Local SettingsTemporary Internet FilesOLK12wetsuwior1tog00.htm N:AutocadMedewerker TVDBStrooiroutes Berkenwoude (1) H:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA2006 NICS Operations Report PDF.wpd V:SHAREDNICS SHAREDEDASDRAFTSKisnerOPS 20072007 Operations Report PDF.wpd ![]() V:SHAREDNICS SHAREDEDASDRAFTSKisnerOPS 2008FINAL OPs 2008Copy of 2008 NICS OPERATIONS REPORT PDF.wpd Sfgvp12FEBCOBiaProjectenZeusZeuswerkODPPwerkChrisLogo´sdefensie.wmf, sfgvp12FEBCOBiaProjectenZeusZeuswerkODPPwerkChrisLogo´sdefensie.wmf, sfgvp12FEBCOBiaProjectenZeusZeuswerkODPPwerkChrisLogo´sdefensie.wmf G:Realisatie en BeheerTeam Vastgoed en ProjectenStedenbouwKimAlgemeenkomgrenzenkomgrenzen Layout1 (1) Financiële werkinstructiesWerkmap Gerard3TekentjesLogo defensie.gifį:dataProjectenCivTecGroenBomenbeleidsplanBomenbeleidsplan 25-10-2010 Totaal (1) U:wp51wp51verlof tbsgesteldeverlof tbs gestelde 7-7-2010.wpd Sk1ntdata03homedir$MRoosDesktopTekening deel 1.xps Tante-eshome$LienekeSdatapdfHeffingsverordening Marktgelden Zeeburg 2009, tabel 2009.d… VAF0002groups03$COAlHDPDPLMAPMPmm100 Projecten190 Business Proces Redesign296Fase 11a-04-Digitaliseren formulierenPi Digitale formulierenkastLogo defensie.gif Furthermore, these are some network/directory paths found in Title and Hyperlinks tags:
