Technical Detail

Every browser talks about private browsing in a different way.  So we’ve looked around for a simple, impartial and authoritative approach to the subject, and discovered that Stanford, a leading US University, wrote a report in 2010 entitled “An Analysis of Private Browsing Modes in Modern Browsers”

Here is the key table from that report that compares the type of data that is left accessible after a private browsing session in Firefox, Safari, Chrome and Internet Explorer; and we’ve added a column on the end describing Wipeout’s capability.

A “no” or an “n/a” is good; because it means the data is not accessible (“no”), or the browser doesn’t offer that function (“n/a”) so there’s nothing to wipe out.  A “Yes” means that some data is left accessible after the private browsing; albeit it may not be that important.

The reason that all the browsers have a Yes rating for Downloaded items is because the user is choosing to override the private browser by downloading a file to their computer.

Client Certs are not that relevant to “for fun” private browsing as they are mainly used to authenticate users on Corporate Websites.  And SSL security certificates are either auto-accepted by Windows and stored anonymously (“Trusted Certs”), or the user has a choice whether to accept (“Custom Certs”).

Wipeout also removes Flash Cookies (Flash Local Shared Objects), and cleans Index.dat files that refer to deleted temporary internet files.

And although we don’t expect your mates to be forensic experts; to ensure files of all types are thoroughly deleted, Wipeout uses a method of deletion that first overwrites the entire file contents with zeros; then with ones; and then with random data. It then renames the file multiple times to obscure filename records, and finally deletes the file.

Please remember that Wipeout is for those embarrassing moments; the cringe-worthy occasions when friends, family and workmates stumble across stuff you really didn’t want them to see. However if the stakes are high, and your job or family or financial security depends on it; or if you’re looking to break the law; then Wipeout and other free private browsers are not for you.  Read more.

While this computer won’t have a record of your browsing history, your internet service provider or employer can still track the pages you visit.
