Proxy server automatically modifies network resources to protect client devices
A recently granted patent (Publication Number: US12001504B2) discloses a method implemented in a proxy server to modify Internet responses. The method involves receiving requests from client devices, retrieving network resources from origin servers, detecting threats such as malware or elements to be obfuscated, and automatically modifying the content before transmitting it back to the clients. The modifications include replacing sensitive information like email addresses with obfuscation scripts to prevent direct readability by bots. The patent also covers scenarios where server-side defined modifications are applied to exclude or obfuscate specific content based on administrator-defined rules.
Furthermore, the patent details the functionality of the proxy server, which includes a processor and memory to execute the instructions for modifying Internet responses. The server is capable of detecting threats, such as malware, in retrieved network resources and automatically applying modifications to protect client devices. Additionally, the server can identify elements like phone numbers, addresses, and credit card numbers to be obfuscated using obfuscation scripts. The patent also highlights the ability of the server to handle requests from multiple client devices and modify content based on predefined rules, ensuring a secure and privacy-enhancing browsing experience for users.
