Editing Electronic signature (section)

==In contract law==
Since well before the [[American Civil War]] began in 1861, [[morse code]] was used to send messages electrically via the telegraph. Some of these messages were agreements to terms that were intended as enforceable [[contract]]s. An early acceptance of the enforceability of telegraphic messages as electronic signatures came from a [[New Hampshire Supreme Court]] case, Howley v. Whipple, in 1869.<ref>Howley v. Whipple, 48 N.H. 487, 488 (1869)</ref><ref>{{cite web|url=http://crawls-wm.us.archive.org/katrina/20051022073309/http://www.cato.org/speeches/sp-ss031799.html#1b |website=Cato Institute |first1= Solveig |last1=Singleton  |date= March 17, 1999 |title=Privacy Issues In Federal Systems: A Constitutional Perspective |access-date=2015-03-06 |url-status=dead |archive-url=https://web.archive.org/web/20200503153712/http://crawls-wm.us.archive.org/katrina/20051022073309/http://www.cato.org/speeches/sp-ss031799.html#1b |archive-date= May 3, 2020 }}</ref>

In the 1980s, many companies and even some individuals began using fax machines for high-priority or time-sensitive delivery of documents. Although the original signature on  the original document was on paper, the image of the signature and its transmission was electronic.<ref name="ib">{{cite web |url=http://www.isaacbowman.com/the-history-of-electronic-signature-laws |title=The History of Electronic Signature Laws |publisher=Isaac Bowman |date=March 16, 2009 |access-date=2015-03-06 |archive-url=https://web.archive.org/web/20150311072559/http://www.isaacbowman.com/the-history-of-electronic-signature-laws |archive-date=2015-03-11 |url-status=dead }}</ref>

Courts in various jurisdictions have decided that enforceable legality of electronic signatures can include agreements made by email, entering a [[personal identification number]] (PIN) into a bank [[Automated teller machine|ATM]], signing a credit or debit slip with a digital pen pad device (an application of [[graphics tablet]] technology) at a [[point of sale]], installing software with a [[clickwrap]] [[software license agreement]] on the package, and signing electronic documents online.

The first agreement signed electronically by two sovereign nations was a Joint Communiqué recognizing the growing importance of the promotion of electronic commerce, signed by the United States and Ireland in 1998.<ref>{{Cite web |date=September 1998 |title=International Law In Brief |url=http://www.asil.org/ilib/ilib0104.htm#04 |url-status=dead |archive-url=https://web.archive.org/web/20120331012531/http://www.asil.org/ilib0104.cfm |archive-date=Mar 31, 2012 |website=American Society of International Law}}</ref>

In 1996 the [[United Nations]] published the UNCITRAL Model Law on Electronic Commerce.<ref>{{cite web |url=http://www.uncitral.org/pdf/english/texts/electcom/05-89450_Ebook.pdf |title=UNCITRAL : Model Law on Electronic Commerce with Guide to Enactment 1996 with additional article 5 ''bis'' as adopted in 1998 |date=1999 |publisher=UNCITRAL |access-date=2015-03-06 |archive-date=2012-09-12 |archive-url=https://web.archive.org/web/20120912143439/http://www.uncitral.org/pdf/english/texts/electcom/05-89450_Ebook.pdf |url-status=dead }}</ref> Article 7 of the UNCITRAL Model Law on Electronic Commerce was highly influential in the development of electronic signature laws around the world, including in the US.<ref>{{cite web|url=http://www.unidroit.org/english/publications/review/articles/2000-4-gabriel-e.pdf|title=The New United States Uniform Electronic Transactions Act: Substantive Provisions, Drafting History and Comparison to the UNCITRAL Model Law on Electronic Commerce|last1=Gabriel|first1=Henry|publisher=International Institute for the Unification of Private Law |access-date=30 April 2011|archive-date=September 29, 2011|archive-url=https://web.archive.org/web/20110929055237/http://www.unidroit.org/english/publications/review/articles/2000-4-gabriel-e.pdf|url-status=live}}</ref> In 2001, UNCITRAL concluded work on a dedicated text, the UNCITRAL Model Law on Electronic Signatures,<ref>{{cite web |url=http://www.uncitral.org/pdf/english/texts/electcom/ml-elecsig-e.pdf |title=UNCITRAL : Model Law on Electronic Signatures with Guide to Enactment 2001 |publisher=UNCITRAL |date=2002 |access-date=2015-03-06 |archive-date=2012-08-02 |archive-url=https://web.archive.org/web/20120802172559/http://www.uncitral.org/pdf/english/texts/electcom/ml-elecsig-e.pdf |url-status=dead }}</ref> which has been adopted in some 30 jurisdictions.<ref>{{cite web |url=http://www.uncitral.org/uncitral/en/uncitral_texts/electronic_commerce/2001Model_status.html |title=Status - UNCITRAL Model Law on Electronic Signatures (2001) |publisher=UNCITRAL |access-date=2015-03-06 |archive-date=February 22, 2014 |archive-url=https://web.archive.org/web/20140222040526/http://www.uncitral.org/uncitral/en/uncitral_texts/electronic_commerce/2001Model_status.html |url-status=dead }}</ref> Article 9, paragraph 3 of the [[United Nations Convention on the Use of Electronic Communications in International Contracts]], 2005, which establishes a mechanism for functional equivalence between electronic and handwritten signatures at the international level as well as for the cross-border recognition. The latest UNCITRAL text dealing with electronic signatures is article 16 of the UNCITRAL Model Law on the Use and Cross-border Recognition of Identity Management and Trust Services (2022).

Canadian law ([[Personal Information Protection and Electronic Documents Act|PIPEDA]]) attempts to clarify the situation by first defining a generic electronic signature as "a signature that consists of one or more letters, characters, numbers or other symbols in digital form incorporated in, attached to or associated with an electronic document," then defining a secure electronic signature as an electronic signature with specific properties. PIPEDA's secure electronic signature regulations refine the definition as being a digital signature applied and verified in a specific manner.<ref>[http://laws.justice.gc.ca/en/showtdm/cr/SOR-2005-30//?showtoc=&instrumentnumber=SOR-2005-30] {{webarchive|url=https://web.archive.org/web/20110605050917/http://laws.justice.gc.ca/en/showtdm/cr/SOR-2005-30//?showtoc=&instrumentnumber=SOR-2005-30|date=June 5, 2011}}</ref>

In the [[European Union]], EU [[Regulation (European Union)|Regulation]] No 910/2014 on electronic identification and trust services for electronic transactions in the European [[European Single Market|internal market]] ([[eIDAS]]) sets the legal frame for electronic signatures. It repeals [[Directive (European Union)|Directive]] 1999/93/EC.<ref name="eIDAS_Reference" /> The current and applicable version of eIDAS was published by the [[European Parliament]] and the [[European Council]] on July 23, 2014. Following Article 25 (1) of the eIDAS regulation, an [[advanced electronic signature]] shall “not be denied legal effect and admissibility as evidence in legal proceedings". However it will reach a higher [[Relevance (law)|probative value]] when enhanced to the level of a [[qualified electronic signature]]. By requiring the use of a [[Secure signature creation device|qualified electronic signature creation device]]<ref>eIDAS regulation Article 3 (12)</ref> and being based on a certificate that has been issued by a qualified trust service provider, the upgraded advanced signature then carries according to Article 25 (2) of the eIDAS Regulation the same legal value as a handwritten signature.<ref name="eIDAS_Reference" /><ref name="Turner-AdvancedESig">{{cite web|last1=Turner|first1=Dawn M.|title=Advanced Electronic Signatures for eIDAS|url=http://www.cryptomathic.com/news-events/blog/advanced-electronic-signatures|publisher=Cryptomathic|access-date=7 June 2016|archive-date=June 30, 2016|archive-url=https://web.archive.org/web/20160630080430/http://www.cryptomathic.com/news-events/blog/advanced-electronic-signatures|url-status=live}}</ref> However, this is only regulated in the European Union and similarly through [[ZertES]] in [[Switzerland]].

The U.S. Code defines an electronic signature for the purpose of US law as "an electronic sound, symbol, or process, attached to or logically associated with a contract or other record and executed or adopted by a person with the intent to sign the record."<ref name="US ESIGN Act of 2000">{{cite web |url=http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=106_cong_public_laws&docid=f:publ229.106.pdf |title=Public Law 106-229 : June 30, 2000 : Electronic Signatures in Global and National Commerce act |publisher=Frwebgate.access.gpo.gov |access-date=2015-03-06 |archive-date=May 22, 2011 |archive-url=https://web.archive.org/web/20110522212411/http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=106_cong_public_laws&docid=f:publ229.106.pdf |url-status=live }}</ref> It may be an electronic transmission of the document which contains the signature, as in the case of [[facsimile]] transmissions, or it may be encoded message, such as [[telegraphy]] using [[Morse code]].

In the United States, the definition of what qualifies as an electronic signature is wide and is set out in the [[Uniform Electronic Transactions Act]] ("UETA") released by the National Conference of Commissioners on Uniform State Laws (NCCUSL) in 1999.<ref>{{cite web |url=http://www.law.upenn.edu/bll/ulc/fnact99/1990s/ueta99.htm |title=Biddle Law Library: Library: • Penn Law |publisher=Law.upenn.edu |access-date=2015-03-06 |archive-url=https://web.archive.org/web/20140814230534/https://www.law.upenn.edu/bll/ulc/fnact99/1990s/ueta99.htm |archive-date=2014-08-14 |url-status=dead }}</ref> It was influenced by [[American Bar Association|ABA]] committee white papers and the uniform law promulgated by NCCUSL. Under UETA, the term means "an electronic sound, symbol, or process, attached to or logically associated with a record and executed or adopted by a person with the intent to sign the record."
