Captcha staat voor \"Completely Automated Public Turing Test to Tell Computers and Humans Apart\" (Volledig geautomatiseerde openbare turingtest om computers en mensen uit elkaar te houden). Maar waar komt Captcha vandaan en hoe is het in de loop van de tijd tot stand gekomen? In dit artikel geven we een blik op de geschiedenis van Captcha's.<\/h5>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>De oorsprong van Captcha's<\/strong><\/h3>\n\n\n\n<p>Die Entwicklung von Captchas geht zur\u00fcck auf das Jahr 1997, wenn der Computerwissenschaftler Mark D. Lillibridge am Carnegie Mellon University eine L\u00f6sung zur Bek\u00e4mpfung von Spam in Online-Foren suchte. Hij stelde dat herk\u00f6mmliche Captcha's, zoals die Erkennung von verzerrten Buchstaben und Zahlen, von Spammern leicht umgangen werden konnten, indem sie optische Zeichenerkennungssoftware einsetzten. Lillibridge ontwikkelde hiervoor een nieuwe Captcha, die gebaseerd is op afbeeldingen van Tieren, die de gebruiker kan gebruiken om zijn mannelijke identiteit te achterhalen. Dit Captcha-systeem werd \"Animal Species Image Recognition\" genoemd.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Ontwikkeling van tekst-basierten Captcha's<\/strong><\/h3>\n\n\n\n<p>In de daaropvolgende jaren waren tekstgebaseerde Captcha's geloviger, omdat ze eenvoudig te implementeren waren en door de meeste gebruikers eenvoudig te verwijderen waren. Die Captcha's verwenden verzerrte Buchstaben und Zahlen, die der Benutzer manuell eingeben muss, um seine Identit\u00e4t zu beweisen. Deze methode werd aangeduid als \"Reverse Turing Test\", omdat de gebruiker moest weten dat hij een mens was, als hij een opdracht uitvoerde die door een computer niet kon worden uitgevoerd.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Verbeteringen van Captcha's in de loop van de tijd<\/strong><\/h3>\n\n\n\n<p>Met de zunehmenden Verbreitung von Captchas wurden auch die Versuche von Spammern und automatisierten Angriffen immer ausgefeilter. Daarom werden er in de loop van de tijd meer verbeteringen aangebracht om de werking van Captchas te verbeteren. Een voorbeeld hiervan zijn audiogebaseerde Captchas, die ontwikkeld werden om gebruikers met Sehbehinderungen de mogelijkheid te bieden Captchas te l\u00f6sen.<\/p>\n\n\n\n<p>In 2009 werd reCaptcha ontwikkeld, een Captcha-systeem dat is ontwikkeld door Google. Dit systeem maakte gebruik van de macht van de mensheid om boeken te digitaliseren, zodat gebruikers Captcha's kregen die uit verzerrten woorden en zinnen bestonden, die door optische zeichenerkenningssoftware niet konden worden herkend. Als een Benutzer de Captcha erfolgreich gel\u00f6st heeft, werd het woord of de zin in een tekst omgezet, die gebruikt werd voor de digitalisering van boeken.<\/p>\n\n\n\n<p>In het jaar 2014 ontwikkelde Google een nieuw Captcha-systeem namens \"No Captcha reCaptcha\", dat slechts een eenvoudige klik of een zoekopdracht van de gebruiker vereist om te zien of hij een mens is. Dit systeem maakt gebruik van fortschrittliche Technologien wie Machine Learning en Analyse von Benutzerverhalten, um zu erkennen, ob der Benutzer tats\u00e4chlich ein Mensch ist oder nicht.<\/p>\n\n\n\n<p>Hoe die Zukunft der Captcha aussehen zal, leest u hier: Die Zukunft von Captcha's: Wie werden die Captcha's der Zukunft funktionieren?<\/p>\n\n\n\n<p>Unsere Captcha-L\u00f6sung wurde mit Hilfe modernster Technologien entwickelt, um Spam und Missbrauch effektiv zu verhindern, ist au\u00dferdem benutzerfreundlich und verursacht keinerlei Probleme f\u00fcr bestimmte Benutzergruppen durch l\u00e4stige R\u00e4tsel oder andere Aufgaben, die zu l\u00f6sen sind.
