More Secure VPN Tunnel (NOA): U.S. Patent plus European Patent Application

The Virtual Private Network (VPN) has been around for over 20 years and is a common method of connecting your PC or mobile device with an outside network. A VPN Tunnel connects your smartphone, laptop, computer or tablet to an outside network, but keeps your IP address hidden and encrypts all the data you generate. By connecting to websites through a VPN tunnel – and not directly – government agencies, hackers and others cannot track your online activity or even view your IP address! A VPN tunnel is useful when one is logging onto the Internet using public Wi-Fi at hotels, airports, coffee shops, libraries and other public places.

This patent takes the VPN Tunnel to the next level by enabling more secure initial and continuous authentication of the connection. The patent uses USB hardware to route all VPN traffic through the device, enabling easier set-up and administration with higher security, and the option to use biometric or other authentication hardware. VPN software, certificates, credentials and sensors are stored on the device, allowing for greater security and manageability. This patented device continuously authenticates the presence of the user via biometrics or a second device which can be a smartphone, smartwatch, NFC ring or a custom device using Quick Response (QR) Codes, Near-Field Communication (NFC) or Bluetooth Low Energy (LE) proximity authentication to activate or deactivate the VPN tunnel.

U.S. Patent No. 10,412,070 for a “Method and apparatus of implementing a VPN tunnel” is part of a portfolio that also includes European Patent Application 3472719. Any current supplier of VPN Tunnel services or equipment will be able to take its product offerings to the next generation and leapfrog the technology and product offerings of all of its competitors!

Secure VoIP Voice, IM, Video, SMS and P2P (Lesavich): U.S. Patent No. 7,852,831

VoIP (or Voice over Internet Protocol) is now a common, less expensive and more adaptable alternative to conventional telephone service. You can do more via VoIP (like send data and video) than you can do – or at least do easily – with a conventional landline telephone.

This patent covers the foundational concept behind securely sending voice calls as well as video, IM (instant messaging), SMS (short message service) and P2P (peer-to-peer) communications over the Internet and other communications networks such as a PSTN (public switched telephone network) to and from any network device, and do so while maintaining privacy, security and quality of service for the users on both ends. FXO (Foreign Exchange Office) and FXS (Foreign Exchange Solution) interfaces are included in the patent, making international VoIP calls possible! The invention covered by this patent enables a network device to function as an IP PBX (private branch exchange) or a private VoIP gateway, and to provide and control VoIP voice communications without using other public or private VoIP gateways or VoIP servers or devices. And VoIP hardware and software components are covered in this most comprehensive patent for both wired and wireless VoIP communications.

U.S. Patent No. 7,852,831 for "Method and system for providing private virtual secure Voice over Internet Protocol communications" is both robust and foundational. The patent has 15 Claims, a 2005 Priority Date, a Patent Term Adjustment of 1,387 days, and over 200 Forward Citations! It would be a strategic acquisition for any company providing VoIP services including VoIP voice and video calling services similar to Skype and Facetime.
