Not every guest walking through your door is going to be switched-on. Some won’t read the fine print. Others will click through anything just to get to the fun part. That’s exactly why your waiver process needs to be airtight: every security measure in place, every question foolproofed, and full compliance with E-Sign law.
In fact, regulators and insurers constantly watch how you deliver information to customers and how you prove they understood it. So E-Sign law isn’t a box-ticking exercise, and e-signatures, digital signatures, and digital watermarks are not the same thing. Confuse them, and you could expose your business.
What is E-Sign Law?
Most companies rely on e-signatures. In the US, the Electronic Signatures in Global and National Commerce Act (ESIGN) protects them, defining an electronic signature as “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” (15 U.S. Code § 7006).
Insurers like them too. After all, unlike paper, digital records don’t get damaged, get lost, or wash away in the rain, and you can search them instantly.
Three ways to secure an electronic document
There are three main ways to validate an electronic document.
1. Electronic signature
Wherewolf customers use this one every day. It shows the signer approved the document’s contents, and, paired with details like date of birth, email, and name, it confirms who they are. The US E-Sign Act protects it.
2. Digital signature
This uses cryptography to prove no one tampered with a document since signing. Usually, a third-party digital certificate or stamp validates the document’s integrity, so it’s about the software, not the signer.
3. Digital watermark
A watermark embeds identifying code directly into a file to show who owns it. Businesses typically use it to protect intellectual property and prevent copyright infringement, though it can also show a file hasn’t been altered post-signature. The US Digital Millennium Copyright Act (DMCA) defines it as “a set of data embedded in a digital work which identifies the work and/or its copyright owner or provides other information about the work” (17 U.S. Code § 512).
These terms are not interchangeable
An electronic signature proves the signer approved and intended to sign. Meanwhile, a digital signature protects the document’s integrity rather than the signer’s intent. A digital watermark, on the other hand, protects ownership. Since no one actions it, it says nothing about anyone’s agreement.
A real-world stakes test: Florida’s SB 606
Florida’s Fish and Wildlife Conservation Commission passed SB 606 to tighten up boating safety education compliance (Fla. Stat. § 327.395). Since January 1, 2023, operators must deliver pre-rental safety instruction to renters, and “the statement form must be signed by the individual providing the instruction.”
Here’s the catch: the ESIGN Act requires that whoever is signing, guest or instructor, actually reviews the document first. So if you slap a signature or watermark on before that review happens, even to speed things up, you violate the ESIGN Act. That’s a liability risk to your entire operation.
Put plainly, you can’t pre-stamp a waiver before someone reads it, and you can’t declare in advance that they understood and agreed. Under SB 606, the instructor’s co-signature exists specifically to prove the renter understood the safety briefing.
Wherewolf is the only digital waiver system that lets both guests and instructors co-sign a document only after they’ve reviewed it, so you stay fully compliant with the ESIGN Act. Request a demo to see it in action.
