Latest Patents

One of Ladd's latest patents involves using a zero-knowledge proof to verify that a website visitor is a legitimate human user. In this invention, a client device receives a challenge request from a server to prove that internet traffic was initiated by a human user through verifying a physical interaction with a hardware component. The client device prompts the user to perform this interaction, and upon confirmation, generates a zero-knowledge proof of the attestation signature for server verification. This process ensures that the requested content is only delivered after the server validates the proof.

Another significant patent focuses on establishing a cryptographic tunnel between two endpoints, where the private key used during the tunnel establishment is remotely located. In this scenario, a responder device receives a request from an initiator device to initiate a cryptographic tunnel. The responder device does not contain a static private key but instead communicates with a key server to obtain the necessary keys for secure data transmission. This innovative approach enhances the security of data exchanges over cryptographic tunnels.
