Abstract

This disclosure introduces digital signature systems having dynamically validated, multi-level signature seals. An exemplary digital signature system includes a multi-level signature seal with an attestation and machine-readable code configured to direct a user, upon scanning or selecting the machine-readable code, to a validation portal for the attestation. The validation portal includes an artifact graphically indicating a current validation status of the attestation and a validation link configured to direct the user, upon selection, to multi-level signature data for the seal. A user dashboard is provided to allow the conveyor of the seal to manually validate and invalidate the attestation. The user dashboard includes a scans widget that, upon selection, directs a user to a scan details informational view for the seal.

Claims (34)

1 . A computer system including one or more processors, a memory, and a bus that couples the one or more processors including the memory to each other, the memory stores one or programs to define a digital signature system comprising:

a multi-level signature seal comprising:

an attestation for a document made by a conveyor; and

machine-readable code configured to direct a user, upon scanning or selecting the machine-readable code, to a validation portal for the attestation;

the validation portal comprising:

an artifact graphically indicating a current validation status of the attestation; and

a validation link configured to direct the user, upon selection, to multi-level signature data comprising static information that is available in the document, static information that is not available in the document, and dynamic information that is not available in the document; and

a user dashboard configured to allow the conveyor to manually validate and invalidate the attestation, the user dashboard comprising a scans widget that, upon selection, directs the user to a scan details informational view.

2 . The computer system of claim 1 , wherein the scan details informational view comprises a scan count widget depicting at least one of a total number of unique scans of the multi-level signature seal and a total number of scans of the multi-level signature seal.

3 . The computer system of claim 1 , wherein the scan details informational view comprises a list of entities that have verified the attestation of the multi-level signature seal.

4 . The computer system of claim 3 , wherein the scan details informational view further comprises one or more of location information and contact information for each respective entity on the list of entities.

5 . The computer system of claim 3 , wherein the scan details informational view further comprises one or more of a scan date and a scan location for each respective entity on the list of entities.

6 . The computer system of claim 3 , wherein the scan details informational view further comprises a notification status field.

7 . The computer system of claim 6 , wherein the notification status field comprises a dynamic field that allows a user to choose a notification option.

8 . The computer system of claim 6 , wherein, upon selection of a first notification option, the digital signature system provides the user with a notification update, using a predetermined contact method, if the conveyor changes a seal status of the document.

9 . The computer system of claim 1 , wherein the attestation comprises at least one of a seal, a stamp, and a certification made on authority of the conveyor.

10 . The computer system of claim 1 , wherein the machine-readable code comprises a barcode or quick response (QR) code.

11 . A method for a digital signature system, the method comprising:

providing a multi-level signature seal comprising:

an attestation for a document made by a conveyor; and

machine-readable code configured to direct a user, upon scanning or selecting the machine-readable code, to a validation portal for the attestation;

providing the validation portal comprising:

an artifact graphically indicating a current validation status of the attestation; and

a validation link configured to direct the user, upon selection, to multi-level signature data comprising static information that is available in the document, static information that is not available in the document, and dynamic information that is not available in the document; and

providing a user dashboard configured to allow the conveyor to manually validate and invalidate the attestation, the user dashboard comprising a scans widget that, upon selection, directs the user to a scan details informational view.

12 . The method of claim 11 , wherein the scan details informational view comprises a scan count widget depicting at least one of a total number of unique scans of the multi-level signature seal and a total number of scans of the multi-level signature seal.

13 . The method of claim 11 , wherein the scan details informational view comprises a list of entities that have verified the attestation of the multi-level signature seal.

14 . The method of claim 13 , wherein the scan details informational view further comprises one or more of location information and contact information for each respective entity on the list of entities.

15 . The method of claim 13 , wherein the scan details informational view further comprises one or more of a scan date and a scan location for each respective entity on the list of entities.

16 . The method of claim 13 , wherein the scan details informational view further comprises a notification status field.

17 . The method of claim 16 , wherein the notification status field comprises a dynamic field that allows a user to choose a notification option.

18 . The method of claim 16 , wherein, upon selection of a first notification option, the digital signature system provides the user with a notification update, using a predetermined contact method, if the conveyor changes a seal status of the document.

19 . The method of claim 11 , wherein the attestation comprises at least one of a seal, a stamp, and a certification made on authority of the conveyor.

20 . The method of claim 11 , wherein the machine-readable code comprises a barcode or quick response (QR) code.
