Students have been literally searching nudity pictures in Google Docs or Slides all the time, touching many school administrators’ and teachers’ nerves. Image searching is a ubiquitous feature in Google Apps (Docs, Sheets, Slides, Forms and Drawings). According to an old report by Mary Meeker in 2014, 1.8 billion images are uploaded every day. It’s not unlikely to find pornography or bloody images nowadays. To comply with the Children’s Internet Protection Act (CIPA) law, admins have to move these contents away from students. How could we prevent students from searching unintended images in Google apps?
While there are other web filtering vendors like OpenDNS / Cisco that can filter malicious or porn sites plus enforce Google SafeSearch for you, admins still notice pornography slipped through the loophole of firewalls. Why? It’s because the image searching results in Docs come from the same server (encrypted-tbn0.gstatic.com) as the normal Google Image Search, blocking the domains / urls won’t prevent students from seeing the thumbnails or even the image itself. On the other hand, it’s strange that Google returns inappropriate image in the Docs that the normal Google Image Search doesn’t.
This article shows how Safe Doc blocks the image search feature to protect students from searching inappropriate images. It removes the image searching feature completely in Google Docs, Sheets, Slides, Forms and Drawings. In this way, students will no longer search random images from the web but use the whitelisted images. The way may not sound dedicated, but it ensures 100% security.
