Latest Patents

One of Landwerth's latest patents focuses on software provenance validation. This innovation reports whether a validation binary matches the source code, resources, and other components, as well as the compiler, runtime, operating system, and other contextual elements specified in a provenance manifest for a release binary. The patent outlines how part context checksums, software versions, tool parameters, and other aspects of a build are checked. It also details how certification signatures, timestamps, and certain version differences may be ignored for validation purposes. The provenance manifest can include other provenance manifests, including binary rewrite manifests, and may be stored in a debugger file with symbol information or separately. Partial matches can be reported, providing details on what matches or does not match. Once the provenance of a binary is validated, the source code can be analyzed for vulnerabilities, thereby enhancing software supply chain security.

Another significant patent by Landwerth involves trimming unused dependencies using a package graph and module graph. This technique allows for the identification of dependencies that are not utilized during the execution of an application. By traversing the package graph and module graph, a version of the application can be configured to include only the dependencies that are used, optimizing the application for deployment.
