US Patent 12111915 Security-enhanced file open and download

A method of downloading or opening a file in response to a user input made through an application running in the computer system, includes the steps of detecting by the application that the user input is to download or open a file, issuing a request by the application to a file sanitation server to sanitize the file to remove embedded codes in the file and return the sanitized file, and upon receiving the sanitized file by the application, saving the sanitized file in a folder where the sanitized file can be opened.
