According to Yahoo.com, the encrypted Google search is beneficial for individuals and businesses to ensure sensitive information isn’t exposed to snoops.
All surfers need to do is type “https” at the beginning of the URL instead of “http.” This sets up an encrypted pipe between the browser and Google so that any search traffic is kept between the user and Google.
Because Google still has a record of the search, it’s not completely private. But many users and businesses still trust in Google’s reputation, which is based on the “do no evil” motto, and trust that the company won’t do anything to violate that trust.
Besides searches that can’t be intercepted, another benefit for businesses is that searches conducted via Google encrypted search are not archived in history and won’t appear in the autofill during a subsequent search, which present a much larger risk of intentional exposure of search terms and cache data stored locally on the computer.
Google encrypted search doesn’t store information on searches regarding research and development, confidential intellectual property, upcoming product or service announcements or other information not intended for unauthorized consumption, so there is no risk of someone finding it.
The beta of Google’s encrypted search only works with the core search functionality, not images, videos or maps. It also doesn’t keep the browser history clear of URLs that are entered directly, as opposed to Google search.
