Abstract

A system and method for enabling electronic signing of an unsigned electronic document over the internet or similar network. Responsive to receipt of document and signer information from a document sender, a document execution server makes available to all signer users over a network, the unsigned electronic document, together with signature fields in the document. The document execution server receives over the network, from one or more of the signer users, signature data representative of signer user signatures associated with the respective signature fields of the unsigned electronic document. Responsive to receipt of the signature data from one or more of the signer users, the document execution server generates a signed electronic document corresponding to the unsigned electronic document.

Claims

1. A method for enabling electronic signing of an unsigned electronic document over a network, wherein the unsigned electronic document includes content displayable to one or more signer users as text and/or graphics on one or more pages, and one or more signature fields at one or more locations on the pages, wherein the signature fields are adapted to receive a signature of one of said signer users, comprising the steps of:

(a) receiving over the network the unsigned electronic document from a document sender via a document execution server together with signer party data representative of the identities of one or more signer users who are to sign the unsigned electronic document,

(b) making available the unsigned electronic document to all signer users over the network via said document execution server together with a dynamic online signature entry pad associated with each signature field in the unsigned electronic document, said dynamic online signature entry pad also made available over the network via said document execution server,

(c) receiving signature data over the network from one or more of the signer users via said document execution server, the signature data representative of one or more biometric actions by the respective signer users corresponding to entry of signer user signatures to the dynamic signature entry pads associated with the respective signature fields of the unsigned electronic document, and

(d) generating a signed electronic document corresponding to the unsigned electronic document in response to receipt of the signature data from one or more of the signer users, wherein the signed electronic document includes information representative of the signatures of the signer users, and wherein the signed electronic document is displayable to signer users with the text and/or graphic content and signature fields of the unsigned electronic document and a graphical representation of the received signature data in the respective signature fields.

2. The method according to claim 1, comprising a further step of:

establishing the unsigned electronic document received over the network from the document execution server to be web-ready following step (a) and prior to step (b) using said document execution server.

3. The method according to claim 1 wherein the document sender is one of said signer users.

4. The method according to claim 1 wherein the document sender is other than one of said signer users.

5. The method according to claim 1 comprising further steps of:

(e) generating authentication data associated with the received signature data from the respective signer users using the document execution server, wherein the authentication data is not changeable by any party, and

(f) storing the authentication data in association with the signed electronic document using the document execution server.

6. The method according to claim 5 comprising a further step of:

(g) irreversibly coupling the authentication data with the signed electronic document using the document execution server.

7. The method according to claim 1 comprising a further step of:

sending copies of the signed electronic document to the signer users via the document execution server.

8. The method according to claim 1 comprising a further step of:

modifying the unsigned document via the document execution server before step (b) to include flag data interpretable by the respective signer users to successively identify to the respective signer users and the signature fields in the unsigned electronic document which require entry of their signature in the dynamic signature entry pads associated with each signature field in the unsigned electronic document, whereby the modified unsigned electronic document is made available to the respective signer users in step B.

9. The method according to claim 1 comprising a further step of:

generating summary data for each signer user via the document execution server in conjunction with step (b), the summary data interpretable by each signer user to identify the locations in the unsigned electronic document requiring signature by the respective signer users, and sending the summary data to the respective signer users.

10. The method according to claim 1 wherein graphical representation of the signature data received over the network in the respective signature data fields of the signed electronic document for the signer users matches the signatures of the respective signer users.

11. The method according to claim 1 wherein the signer party data representative of the identities of the signer users includes email addresses for one or more of the signer users.

12. The method according to claim 1 wherein the signer party data representative the of identities of the signer users includes SMS addresses for one or more of the signer users.

13. The method according to claim 1 wherein the signer party data representative of the identities of the signer users includes fax numbers for one or more of the signer users.

14. The method according to claim 1 wherein the signer party data representative of the identities of the signer users includes third party server addresses for one or more of the signer users.

15. The method according to claim 1 wherein at least one biometric action corresponds to a free-form signature effected by one of said signer users.

16. The method according to claim 1 wherein at least one biometric action corresponds to a retina scan effected by one of said signer users.

17. The method according to claim 1 wherein at least one biometric action corresponds to an iris scan effected by one of said signer users.

18. The method according to claim 1 wherein at least one biometric action corresponds to one or more fingerprints effected by one of said signer users.

19. The method according to claim 1 wherein the network is the Internet.
