The new policy has a number of different changes compared to the current policy. For instance, Google may acquire information about your hardware models, processor amongst other information something not specifically covered previously. Google has attempted to resolve some of these concerns by restricting other sites using their advertising services from gaining your Google related information. Information security has also considerbly been tightened more specifically including a new "safe browsing feature" and verification steps. Lastly, encryption via SSL is used by Google to secure a connection between you and Google.
Google Dashboard is a tool users possess in order to limit, review and control information displayed and saved by Google. Through an "Ads Preferences Manager" Google will have only a certain amount of information about your searches. The Data Liberation Front for example, is a engineering team from Google that allows you to move or delete any personal information available to Google from use of their services.
