Latest Patents

One of Ban's latest patents is titled "Location confirmation using crowdsourced wireless fingerprints." This invention discloses various embodiments for generating location confirmation models using crowdsourced wireless fingerprints. The technology allows for the generation and association of wireless fingerprints with specific locations during events that require proximity. The collected wireless fingerprints can be analyzed periodically to detect changes in the wireless infrastructure at a given location. If a previously generated location confirmation model is deemed invalid, outdated wireless fingerprints can be removed, and an updated model can be created using current data.

Another notable patent is "Privacy-preserving identity-validated transactions." This invention focuses on anonymously validating the identities of multiple parties involved in a transaction. The system is designed to determine if its location is within a specified proximity threshold and to transmit an arrival indication to a remote computing device. It also facilitates the receipt of an encryption key from the remote device, which is then used to validate the location of a client device.
