Abstract
Methods and systems provide for resolving domain names by employing a proxy server between the client device and the resolving server. The methods and systems may maintain user privacy by the proxy receiving the client identity and an encrypted domain name. After substituting an arbitrary query identifier for the client identity in the resolution request, the proxy forwards the anonymized resolution request to the resolving server. In return the proxy receives an encrypted internet protocol (IP) address with the arbitrary query identifier, which the proxy associates with the client identity and forwards the encrypted IP address to the client for decrypting. Methods and systems provide for receiving an assessment of a full uniform resource locator (URL) in a browser session in advance of the browser accessing the URL. Methods and systems further prevent the re-use of passwords.
