Latest Patents

One of Weichao Dai's latest patents is titled "Protection of interprocess communications in a computer." This invention involves using a protected temporary file for communication between processes running on a host operating system. The file access operation is monitored to ensure that only authorized processes can write messages to the temporary file. This mechanism allows intended processes to read and act on the messages securely.

Another significant patent is "File backup to combat ransomware." This invention monitors operating system events to detect suspicious file change requests.
