Cory Doctorow skriver en kolumn i The Guardian om problemen med filtrering pÄ nÀtet. Tydligen finns det en aktuell debatt om nÀtporr och vad de brittiska internetleverantörerna ska tvingas göra för att förhindra att minderÄriga tar del av den.
Doctorow har tvÄ relevanta invÀndningar. Den ena om att hur svÄrt det Àr att göra de tekniska lösningarna felfria och hur stora konsekvenser det blir av att bara göra fel en gÄng av hundra. NÀtet Àr sÄ stort att siffrorna ÀndÄ blir enorma:
âThink, for a moment, of what it means to have a 99% accuracy rate when it comes to judging a medium that carries billions of publications.
Consider a hypothetical internet of a mere 20bn documents that is comprised one half âadultâ content, and one half âchild-safeâ content. A 1% misclassification rate applied to 20bn documents means 200m documents will be misclassified. Thatâs 100m legitimate documents that would be blocked by the government because of human error, and 100m adult documents that the filter does not touch and that any schoolkid can find."
Den andra invÀndningen Àr att det alltid gÄr att ta sig runt den hÀr typen av spÀrrar:
âWhatâs more, as Hillier was quick to remind me, kids are pretty technologically sophisticated. Kids whose parents rely on this filter will discover quickly that their kids have no trouble evading it. As I discovered on my tour, kids know how to search for open proxies on the internet and to use them to beat the filters. Unfortunately, by driving kids to these filters, we put them at risk of surveillance from another group of unaccountable strangers, as the proxy-operators have the ability to see (and even to interfere with) the kidsâ traffic."
