With a total of 2 patents, Eastman has demonstrated his expertise and innovative thinking in developing solutions that enhance data management and security.

Latest Patents

One of Eastman's latest patents is the "Secure block read and write protocol for remotely stored files." This invention involves a file transfer system that includes a client and a server capable of updating portions of a file stored on the server. The system allows for the uploading of file portions before the file is specified on the client side. The files are stored in raw format at both the client and server, preserving the block list mapping. This protocol is designed to compress and encrypt transferred data, enabling partial file writes while maintaining current bandwidth usage. The write request data structure includes additional features such as flags and fields to ensure reliable transmission of partial file data.

Another significant patent by Eastman is related to "File operations with multiple level file locking techniques." This invention provides file systems with improved locking capabilities. An application on a client workstation communicates through a client driver to a server that interfaces with a metadata database containing locking information about the files. The client driver manages lock and unlock requests for write locks or read locks with intent to write. The server performs read operations and read locking transparently using the metadata database, ensuring efficient file operations.
