What Is an Electronic Notarial Seal? How Digital Seals Replace Physical Stamps
An electronic notarial seal is the digital equivalent of the traditional physical notarial seal (rubber stamp) used by notary publics. Under A.M. No. 24-10-14-SC, an Electronic Notary Public (ENP) applies their electronic notarial seal to documents as part of the e-notarization process, certifying that the notarial act was properly performed.
How It Works
The electronic notarial seal is a cryptographically secured digital marker applied to the electronic document. Unlike a physical rubber stamp that can be reproduced or forged, the electronic seal:
- Is generated using PKI-based cryptography
- Is unique to the specific ENP who applies it
- Is bound to the specific document (cannot be copied to another document)
- Includes metadata such as the date, time, and reference number of the notarial act
- Can be independently verified against the Supreme Court’s centralized database
Why Electronic Seals Are More Secure
Physical notarial seals have a well-documented fraud problem in the Philippines. There have been multiple SC rulings on cases involving fraudulent notarial seals – physical rubber stamps can be duplicated, stolen, or used by unauthorized persons.
| Security Aspect | Physical Notarial Seal | Electronic Notarial Seal |
|---|---|---|
| Duplication | Easy (rubber stamp can be copied) | Near impossible (cryptographic) |
| Unauthorized use | Possible (seal can be stolen) | Protected by private key + ENF access |
| Verification | Visual inspection only | Cryptographic + SC database verification |
| Tamper detection | Difficult | Automatic (any alteration breaks the seal) |
| Audit trail | None | Complete timestamped record |
Verification
Any party can verify an electronic notarial seal by:
- Checking the digital signature embedded in the seal against the ENP’s public certificate
- Verifying the notarial act reference number against the SC’s centralized database
- Confirming the document audit trail for integrity
This verification capability does not exist with physical seals, where the only option is visual comparison – an inherently unreliable method.
Legal Basis
The electronic notarial seal is authorized by A.M. No. 24-10-14-SC and carries the same legal effect as a physical notarial seal. The cryptographic technology underlying the seal draws its legal validity from RA 8792.
