A Google patent could mean that you never again have to remember to switch to incognito mode when searching for presents for your wife (other uses for incognito mode are available). The patent was applied for in 2011 and granted this week.
The patent describes a method by which your browser (presumably Chrome) can work out whether privacy is required “based on the plurality of identifiers.” A diagram in the patent application shows that the browser would analyze the URL, metadata and page content in order to determine whether incognito mode may be appropriate.
The sole example given curiously doesn’t mention browsing online stores for gifts.
Metadata that identifies adult content may automatically trigger that webpage [to] be opened in the privacy mode.
