( CNN ) -- Google says it will spend $ 5 million on an effort to wipe pictures of child sexual abuse from the Web and another $ 2 million to research more effective ways to find , report and eradicate the images . `` The Internet has been a tremendous force for good -- increasing access to information , improving people 's ability to communicate and driving economic growth , '' Jacqueline Fuller , the director of Google Giving , said in a blog post . `` But like the physical world , there are dark corners on the web where criminal behavior exists . '' Part of the $ 5 million will go to established child-protection groups that have been partnering with Google to fight the problem . They include the National Center for Missing and Exploited Children and the Internet Watch Foundation . The Web giant also is creating the Child Protection Technology Fund to develop more efficient ways to fight child porn . Recently , Google has begun using `` fingerprinting '' of child sex-abuse images , Fuller said . It will help law enforcement , Web companies and advocates find and remove the images , as well as prosecute the people who posted them , Google says . `` We 're in the business of making information widely available , but there 's certain 'information ' that should never be created or found , '' Fuller wrote . `` We can do a lot to ensure it 's not available online -- and that when people try to share this disgusting content they are caught and prosecuted . '' Since 2008 , Google has been using technology to tag images , helping the company find them anywhere else they may appear on the Web . Among other things , Google can make sure images or Web pages do not appear in search results . In 2006 , the company joined Microsoft , Aol , Time , Time Warner ( CNN 's parent company ) and others in a Technology Coalition , targeting child abuse on the Web , and has donated hardware and software to groups around the world fighting child sex abuse . The company , which jealously protects details on how its search algorithms and other processes work , did not immediately respond to a message seeking more details about how its new initiative will work and what additional efforts may be on the way . According to the National Center for Missing and Exploited Children , the group 's tip line received 17.3 million images and videos of suspected child abuse in 2011 . That was four times what the group received in 2007 .
Google spent a total of $ 7 million to speed up fight against child porn . Search Engine 's ` ` fingerprinting '' helps find images , and those who post them . Child Protection Technology continues to pay for new tools .
