The Domain Name System (DNS) introduced in 1985 has been a security risk because it allowed internet users' online browsing activities to be tracked and analyzed. Despite many protocols developed to encrypt DNS for the protection of user privacy, websites visited by users can still be identified with high accuracy based on gathered traffic pattern information.

The invention here is an algorithm that incorporates a novel obfuscation method to websites, as demonstrated, encrypted with a DNS-over-HTTPS protocol.

This new algorithm/method reduces the accuracy of traffic analysis from 97% to 7-9%.
