4. A system, comprising: at least one computing device that implements one or more services, wherein the one or more services: receive, from a signatory, a request to generate a signature for a document, wherein the signatory is associated with multiple sets of credentials, wherein a first set of credentials is associated with a first duress level, and wherein a second set of credentials is associated with a second duress level; obtain a document identifier for the document, the document identifier derived based at least in part from document contents; obtain a token identifier for the at least one computing device, wherein the token identifier is registered with an identity registrar and authorized by the identity registrar to generate signatures, and wherein the token identifier comprises a first private key corresponding to a first public key and a second private key corresponding to a second public key; generate a first signature based at least in part on the document identifier, the first set of credentials, and the identity verification identifier, wherein the first signature is based at least in part on encrypting the document identifier using the first private key; determine that the generated first signature is not a match to the received signature of the signatory; generate a second signature based at least in part on the document identifier, the second set of credentials, and the identity verification identifier, wherein the second signature is based at least in part on encrypting the document identifier using the second private key; determine that the generated second signature is a match to the received signature of the signatory; and perform an action in accordance with a duress level associated with the second set of credentials, wherein the action is one or more of hiding information associated with a first account, displaying information associated with a second account, notifying security personnel of a security incident indicated by the duress level, sending a message indicating an occurrence of the duress level, indicating the occurrence of the duress level in a data store, or repudiating transactions associated with the document.

The system of claim 4 , wherein: the multiple sets of credentials include multiple sets of biometric data associated with the signatory; at least one set of the multiple sets of biometric data includes one or more of fingerprint data or finger movement data that indicates an occurrence of a sanctioned signing event; and at least another set of biometric data includes one or more of fingerprint data or finger movement data that indicates an occurrence of an unsanctioned signing event.
