2
Key E-Signature Laws
  • United States
  • Uniform Electronic Transactions Act (UETA)
  • Electronic Signatures in Global and National
    Commerce Act (E-SIGN)
  • European Union
  • Electronic Signatures Directive
  • International Treaty
  • 2005 United Nations Convention on the Use of
    Electronic Communications in International
    Contracts (UN
    E-Contracting Convention)

3
The UN E-Contracting Convention
  • Negotiated 2002-2005 at UNCITRAL
  • Approved by United Nations in November 2005
  • Currently open for signature and ratification
  • Central African Republic, Lebanon, and Senegal
    signed to date
  • Signing ceremony July 2006 at UN
  • Applies to B2B international transactions
  • Non-regulatory approach to
  • remove barriers to international e-commerce
  • provide legal certainty

4
E-Contracting Convention Summary
  • Legal recognition of e-commerce
  • Cant deny enforceability due to electronic form
  • Definition of e-signature
  • E-records and e-signatures satisfy
  • Writing signature requirements
  • Originality requirement
  • Recognition of automated contracts
  • Rules for time and place of sending and receipt
    of messages
  • Rules for human input errors
  • Freedom of contract

5
How Should We Sign an Electronic Document?
Options (1)
  • Digitized handwritten signature
  • e.g.,
  • Typed name of a person
  • e.g., /s/ James Bond
  • Secret code for a person
  • e.g., a PIN number 007
  • Any symbol
  • e.g., X, ?
  • A mouse click
  • e.g.,

How Should We Sign an Electronic Document?
Options (2)
  • Biometric data
  • A fingerprint
  • A retinal scan
  • A voice print
  • A digital signature

E-Signatures
  • Are We Asking the
  • Wrong Question?

8
But How You Sign is Not the Key IssueThe Real
Issues are . . .
  • Identifying who signed (or
    who clicked)
  • Even an X on paper can comply with legal
    signing requirements
  • Ensuring document not altered
  • In other words, is the signed document
    trustworthy?
  • Security -- the missing element in
    e-signature discussions

9
Key Requirements for Trust
  • Authenticity
  • Who really signed the document?
  • Integrity
  • Has the document/signature been altered?
  • Since it was signed?
  • Since it was sent-- e.g., in transmission?
  • Since it was received --e.g., while in storage?
  • Nonrepudiation
  • Evidentiary issues ensuring the signer cannot

  • Falsely deny signing the document
  • Falsely deny the contents of the document

10
Comparison of Requirements for a Valid
E-Signature
  • U.S.
  • Symbol or process
  • Attached
  • Intent
  • ________
  • ________
  • EU
  • Data
  • Attached
  • _________
  • Method of authentication
  • _________
  • UN
  • Method
  • _______
  • Intent
  • Identify signer
  • Reliability

11
The UN Approach
  • Long history of signature issue development at
    UNCITRAL
  • 1992-1996 Initial focus on identity and
    approval
  • 1997-2001 Shift to PKI focus
  • 2002-2005 Shift to reliability appropriate to
    the transaction
  • Ultimate focus on a reliable method to
    establish identity and intent
  • Security is required for enforceability!
  • Doesnt even use term signature
  • Option to prove up non-reliable signature

12
E-Signatures Deemed Reliable?
  • The standard formulation
  • Unique to the signer
  • Capable of independent verification
  • Under the signers sole control
  • Linked to the document signed such that any
    alteration of document or signature is
    detectable
  • But is this necessary or appropriate?
  • UNCITRAL moved away from this approach

13
Establishing Trust in a Signature
  • Trust can be derived from the type of signature
  • E.g., using a PKI digital signature for signing
    and/or digitally locking the document
  • Trust can be derived from the process used
  • E.g., careful authentication of the signer before
    he signs or clicks
  • E.g., carefully controlling access to the signed
    document

14
E-Signature Security Why Should You Care?
  • The level of security may determine
  • Validity of a signature or assent
  • Enforceability of a document
  • Authenticating the source
  • Verifying the integrity
  • Validity of a transaction
  • Admissibility of electronic evidence

15
Security as a Precondition to Admissibility
  • An interesting recent case
  • American Express v. Vinhee (9th Cir.)
  • Electronic records not admissible without
    evidence of adequate security

16
The Key to Electronic Signatures and
E-Transactions
  • PROCESS and
  • SECURITY!
