ESIGN Act vs. eIDAS Compliance
The US Framework: ESIGN & UETA
The ESIGN Act (2000) and UETA provide the legal backbone for e-signatures in the United States. They establish that a signature cannot be denied legal effect solely because it is in electronic form. IUSign captures 'intent to sign' and mandatory consent as required by 15 U.S.C. § 7001.
The EU Standard: eIDAS
eIDAS (Electronic Identification, Authentication and Trust Services) is the EU regulation. It defines three levels: Simple, Advanced (AES), and Qualified (QES). IUSign's SHA-256 chaining and multi-factor authentication align with Advanced Electronic Signature requirements.
