Signer Authentication

Strong identity verification on any device. BlueInk can capture a selfie, a drivers license picture, SMS pin, and more. Know you who your signers are with virtually irrefutable proof of identity.

Strong & Flexible Authentication Options

With configurable authentication for each signer, you can require the right level of identity verification for each document and each signer. All identity verification events are captured in the Certificate of Evidence – a stand alone, cryptographically secured audit trail of the signing process.
