What is an Electronic Signature (e-Signature)?
An electronic signature makes electronic records and signatures as trustworthy and legally binding as their paper equivalents, embedding the signer's identity and the date and time of signing directly into the record in a way that cannot be repudiated later.
A compliant electronic signature must be linked uniquely to one individual, requiring controls such as a unique user ID and password or other authentication method, and must never be reusable by or reassignable to another individual under any circumstances.
Beyond identity, electronic signatures must also convey intent, clearly showing whether the signature represents an approval, a review, an authorship confirmation, or another specific action, so the meaning of the signature is unambiguous to anyone reviewing the record later.
Why is an Electronic Signature (e-Signature) important?
Electronic signatures allow organizations to move away from paper-based approval processes without sacrificing the legal and regulatory standing that a handwritten signature traditionally provided.
Because electronic signatures are tied to audit trails and unique user attribution, they create strong accountability, making it possible to prove who approved a specific record and when, even years after the fact.
Compliant electronic signatures also speed up business processes significantly, since approvals can happen remotely and immediately rather than waiting for a physical document to be signed and routed.
How does an Electronic Signature (e-Signature) work?
A typical compliant electronic signature process includes:
- Identity verification. Confirm the signer's identity through unique credentials.
- Signature application. Capture the signature along with the date, time and meaning of the action.
- Non-repudiation controls. Ensure the signature cannot later be denied by the signer.
- Audit trail linkage. Connect the signature event to the broader audit trail for the record.
- Record binding. Permanently link the signature to the specific record it approves.
- Retention. Retain signature records for as long as the underlying record requires.
Electronic Signature vs. Handwritten Signature
| Comparison | Electronic Signature | Handwritten Signature |
|---|---|---|
| Attribution evidence | Unique login, timestamp, audit trail | Physical signature comparison |
| Speed | Immediate, remote approval possible | Requires physical document routing |
Real-world examples of an Electronic Signature (e-Signature)
A quality manager electronically approves a document revision, with the system capturing their unique identity, the exact timestamp, and the specific meaning of "approved" tied to that record.
A pharmaceutical company uses electronic signatures to approve batch records remotely, eliminating the delay of physically routing paper documents between departments.
An auditor reviewing an approval record confirms the electronic signature is uniquely attributable to a specific individual, supporting the record's regulatory standing during an inspection.
Regulations and standards related to an Electronic Signature (e-Signature)
FDA 21 CFR Part 11 establishes the requirements for electronic signatures to be considered trustworthy and equivalent to handwritten signatures, including unique attribution to an individual, appropriate authentication controls, and protections against repudiation.
Electronic signatures also support the broader ALCOA+ data integrity framework, particularly the attributable and original principles, since a compliant signature clearly identifies who took a specific action on a specific record.

Common mistakes with an Electronic Signature (e-Signature)
Common mistakes include allowing electronic signature credentials to be shared or reused across individuals, directly violating the requirement that a signature be uniquely attributable to one person.
Other problems include failing to clearly convey the meaning of a signature, such as whether it represents approval versus simple review, leaving ambiguity about what the signer actually attested to.
