The Strength of User Vs. System Signing
No one should use a safe that multiple individuals have a key to. System signing based solutions should be avoided to prevent the significant problems that can arise from repudiation issues. Instead, a solution that is easy-to-deploy, verifies signer authenticity, and requires virtually zero-management should be implemented. The CoSign digital signature solution is designed to accomplish all of these things, for a significantly lower cost than a consumer will pay for other digital signature solutions.
