RealMe is a software suite that uses an image-based public key infrastructure (PKI) that embeds cryptographic information in a digital image and then exchanges pieces of that image between a user and a Web application to accomplish a strong, bi-directional multi-factor authentication. This technology combines steganography with applied cryptography, and results in a secure yet low-cost solution for Web sites that exchange confidential information with their users.
ecca-proxy is a Web proxy server that transparently handles Eccentric Authentication key and certificate management. Eccentric Authentication is a protocol designed to make using client certificates easy, secure, and private. The proxy handles the difficult cryptographic details and provides an easy to use interface to the user.
