Hidden Metadata

Classification Key : Exterior Security, Information Disclosure


Any metadata associated with the data traffic in the network reveals information about the originator of that data packet. The packet headers are used for information routing in forward and reverse direction. The information in the packet headers like IP addresses reveal private information about sender’s identity and their location. How can the meta-data associated with the data content be hidden?


Obfuscate the metadata associated with the data. For the web browsing domain, create a middleman between the request sender and the recipient that strips off identity-revealing meta-data from the packet headers. The sender submits the request to the middleman that acts as a proxy. It submits the request to the recipient on behalf of the sender, but removes the values from the tags.
