ProofMark™ uses public-key (asymmetric) cryptography – trusted worldwide – in a totally new way. Our Transient Key technology removes the necessity for long-term protection of private keys in a public/private key pair. The private key is used for a relatively short period of time (an Interval) to generate signatures, and is then destroyed. The use of cross-certification across multiple servers provides a widely witnessed and distributed proof model that is less expensive, easier to manage yet more robust than old-style CA-based hierarchical schemes.

High-velocity, commercial-strength global infrastructures need irrefutable activity and identity documentation. Therefore, transaction processing is intrinsic to ProofMark's technology architecture.

ProofMark's innovative approach to cryptographically signing transactions complements existing PKI architectures, while eliminating the need for a the trusted third party. While identity-based models can provide documentation of who participated in an online event, ProofMark's transaction processing model adds the documentation of what and when - providing a full three dimensions of records proof.

ProofMark's distributed and decentralized architecture allows clients to implement robust solutions while making successful attacks on the enterprise much more difficult. Our distributed solution eliminates exposures associated with the need to maintain the secrecy of RSA private keys. Furthermore, each individual ProofMark is self-contained and verifiable by all involved participants without requiring a trusted third party. The result is a solution that addresses the needs of even the highest-value and highest colume transaction exchanges.
