Age verification system

An Adult Verification System is a computing system used by a website to confirm that the user attempting to access their website is of the age required (usually by law) to view the website's content, which could include sex, nudity, violence or bad language. The Adult Verification System is usually provided by a third-party company. In that way the same company can provide adult verification for multiple websites, thus becoming more user friendly.

In 1999, Adult Verification Systems were at the centre of a police crackdown on internet users viewing child pornography, known as Operation Ore, in which web users using their credit cards to verify their age were identified by their financial records when the company which stored the data, Landslide Inc., went into liquidation.
