Google has denied that it tracks people using Incognito mode in the Chrome web browser, after a study suggested the search giant could use its vast web presence to do so. Incognito mode claims to offer web users the ability to browse privately in Chrome without Google collecting their browsing history, cookies, site data or other online data. A study by Professor Douglas Schmidt, a researcher at Vanderbilt University in Tennessee, discovered that Google could retroactively link someone's incognito mode activity to the account information from Google-owned services, like Gmail and YouTube. Professor Schmidt explained in the study: "While such data is collected with user-anonymous identifiers, Google has the ability to connect this collected information with a user's personal credentials stored in their Google Account." There are a lot of Easter Eggs hidden in Chrome, and more and more are discovered each year.
