Abstract: The present invention relates to systems and methods for anonymously personalizing web content to a particular user. The methods and systems may include listening for requests including code and tags that stand for personalized information. Once a request is identified, the personal information for the user corresponding to the tags of the request may be masked by generating anonymized personalization elements. These anonymized personalization elements are elements in a web browser which are enabled to display the personal information from a different domain without allowing front-end scripting on the containing document to get access to the personal information. The anonymized personalization elements may be an iframe, in some embodiments. Lastly, an output, including the anonymized personalization elements, is returned.
