Some embodiments include receiving, at the high trust signature mobile device, a signature request regarding a document that requires a high trust digital signature. The signature request includes a one-time signer authentication code. The document that requires the high trust digital signature is displayed on the mobile device. Then a plurality of signer verification elements is obtained. Obtaining a plurality of signer verification elements includes obtaining from the signer a signer-specific password. Furthermore, it includes automatically applying the one-time signer authentication code obtained from the signature request. Then the signature request is replied to by providing the plurality of signer verification elements to a server system for verification. Once the signer verification elements are validated, the high trust signature is applied to the document. ## Claims ### Claim 1 A method, comprising: at a mobile device having one or more processors and memory storing one or more programs configured for execution by the one or more processors: receiving, from an external device, a signature request regarding a document that requires a high trust digital signature by a signer associated with the mobile device, the signature request including an access link to an authentication form; in response to (i) user selection of the access link and (ii) user input to provide required authentication elements, including a signer-specific username and signer-specific password, displaying the document on a user interface of the mobile device; receiving user input in the user interface to supply a digital signature; embedding the digital signature into the document; and returning the document, with the embedded digital signature, to the external device. ### Claim 2 (depends on 1) The method of claim 1, wherein the required authentication elements further comprise a reason for signing specified by the signer. ### Claim 3 (depends on 1) The method of claim 1, wherein the required authentication elements further comprise biometric information of the signer. ### Claim 4 (depends on 1) The method of claim 1, wherein the required authentication elements further comprise, when the signer has not received previous signature requests, an image of the signer captured from a camera on the mobile device, and the document is displayed on the mobile device only after receiving approval from an administrative operator viewing the image. ### Claim 5 (depends on 4) The method of claim 4, wherein the administrative operator views the signer as well as the evidence of identity in a live video communication. ### Claim 6 (depends on 1) The method of claim 1, wherein: the required authentication elements are validated by a cloud-based validation service; and upon obtaining validation, the digital signature is embedded into the document. ### Claim 7 (depends on 1) The method of claim 1, wherein displaying the document on the user interface of the mobile device includes designating a specific location in the document for the digital signature, the method further comprising receiving the user input at the specific location. ### Claim 8 (depends on 7) The method of claim 7, wherein the specific location includes a specified page within the document. ### Claim 9 (depends on 8) The method of claim 8, wherein the specific location includes a specified position on the specified page. ### Claim 10 A mobile device, comprising: one or more processors; memory; and one or more programs stored in the memory, the one or more programs comprising instructions for: receiving, from an external device, a signature request regarding a document that requires a high trust digital signature by a signer associated with the mobile device, the signature request including an access link to an authentication form; in response to (i) user selection of the access link and (ii) user input to provide required authentication elements, including a signer-specific username and signer-specific password, displaying the document on a user interface of the mobile device; receiving user input in the user interface to supply a digital signature; embedding the digital signature into the document; and returning the document, with the embedded digital signature, to the external device. ### Claim 11 (depends on 10) The mobile device of claim 10, wherein the required authentication elements further comprise a reason for signing specified by the signer. ### Claim 12 (depends on 10) The mobile device of claim 10, wherein the required authentication elements further comprise biometric information of the signer. ### Claim 13 (depends on 10) The mobile device of claim 10, wherein the required authentication elements further comprise, when the signer has not received previous signature requests, an image of the signer captured from a camera on the mobile device, and the document is displayed on the mobile device only after receiving approval from an administrative operator viewing the image. ### Claim 14 (depends on 13) The mobile device of claim 13, wherein the administrative operator views the signer as well as the evidence of identity in a live video communication. ### Claim 15 (depends on 10) The mobile device of claim 10, wherein: the required authentication elements are validated by a cloud-based validation service; and upon obtaining validation, the digital signature is embedded into the document. ### Claim 16 (depends on 10) The mobile device of claim 10, wherein displaying the document on the user interface of the mobile device includes designating a specific location in the document for the digital signature, the one or more programs further comprising instructions for receiving the user input at the specific location. ### Claim 17 (depends on 16) The mobile device of claim 16, wherein the specific location includes a specified page within the document. ### Claim 18 (depends on 17) The mobile device of claim 17, wherein the specific location includes a specified position on the specified page.
