The first prototype of this system, dubbed Vipul’s Razor, was released as an open source project in 1998.3
In 2001, along with a major update (Razor2), VIPUL VED PRAKASH and ADAM O’DONNELL cofounded Cloudmark to work on the technology in a dedicated setting.
Today, the collaborative classifier that underlies Razor2 and all of Cloudmark’s products is known as the CNC (Cloudmark Network Classifier), a reputation metric analyzer that ensures the integrity of user-submitted feedback by modeling historical consensus and disagreement in the recipient community. The goal of the CNC is to ascertain the disposition of report (spam/legit) based on the first few reports, so only a few reporters have to train the classifier for a new spam attack, thus significantly reducing the overall training cost.
