In response to complaints from many quarters and also to strengthen authentication processes and security on the Internet, certificate authorities and browser formed in 2006, an industry association called the CA / Browser Forum that created the specifications of a new type of certificate, called "Extended Validation (EV)". In this case, the CA performs a candidate's enhanced analysis to increase the level of confidence in the company. The browser display is improved and it is easy to see the difference immediately. This is an example of EV Certificate:
OU = MarketWare EV SSL Certificate * Powered by Comodo
OU = "Provided by Marketware - Soluções para Mercados Digitais, Lda."
O = "Marketware - Solucoes para Mercados Digitais, Lda."
Object Identifier (2 5 4 9) = R. Olavo D Eca Leal 4 b
L = Lisboa
ST = Lisboa
Object Identifier (2 5 4 17) = 1600-306
C = PT
In this example, it is clear that the certificate (and the site) belong to Marketware - Solutions for Digital Markets, Lda, Lisbon, Portugal This information was verified by the CA through an analysis that included the examination of corporate documents, verification of individual identity of the candidate and the information query on a third-party database.
Also, all browsers provide visual cues (typically a padlock or green address bar) to indicate that the site uses an EV certificate. This makes it much easier for consumers to know that the site's identity was widely verified. All browsers show the organization's name to the left or right of the URL. The figure below shows how the EV certificates are displayed in popular browsers. Improved analysis makes it much more difficult to obtain EV Certificates.
Thus, EV Certificates help establish the legitimacy of a company that claims to operate a website and provide a way that can be used to help treat problems related to phishing, malware and other forms of online identity fraud.
