In the blog post that Google published regarding its collecting of WiFi data, Alan Eustace, Senior VP, Engineering & Research at Google made an announcement that many seem to have not noticed due to the much more important main issue. However, it is still interesting nonetheless. The announcement is that Google will start offering encrypted search from next week.
This is what Alan Eustace wrote in that blog post:
Earlier this year, we encrypted Gmail for all our users, and next week we will start offering an encrypted version of Google Search.
Other than this sentence, Google has not any other announcement regarding this and has reportedly denied any comments on how the encrypted search will work. However this means that the next time you google something through an open WiFi, you can atleast get some data security.
