# A Digital Seal Should Carry the Same Trust as a Physical One

[See all articles](https://cpcs-scip.ca/carillon-information-security-blog)

Professional associations have spent decades protecting the use of seals and signatures. A member cannot hand their physical seal to a colleague and ask them to authenticate work on their behalf. A photocopy of a sealed page would not, by itself, establish that the recipient holds the original.

An association does not need to operate a certificate authority to bring those principles into the digital world. It can set the requirements for professional eligibility, control and verification, then select a provider capable of meeting them.

An image of a seal and handwritten signature can make a PDF look authentic, but the images alone cannot show who applied them or whether the file changed afterward. If an association is considering a digital signing service for members, preserving the meaning of its seal is a better starting point than reproducing its appearance.

## What should the service demonstrate?

Requirements already used by professional associations offer a practical model:

- Professional eligibility: Only authorized members can obtain and use a credential associated with the association’s designation or seal.
- Association oversight: The association can suspend or withdraw that authorization when a member’s status changes.
- Individual control: The credential remains under the professional’s control, with safeguards against use by someone else.
- Verifiable documents: Recipients can check who signed and whether the signed content changed.
- Established technology: The provider uses public-key infrastructure and standards-based certificates, such as X.509.
- Practical fit: Members can use the service with their document software, and recipients can see the relevant seal, signature and date.
- Dependable service: The provider has the experience, support and resources to maintain the program over time.
  
  The association defines who is authorized, how status changes are handled and what assurance a recipient should receive. The provider supplies the technology and service to put those decisions into practice.
  
  Moving from paper to PDF should not reduce confidence in a professional seal. Done well, it gives the recipient something paper could not: a way to verify the signer and the integrity of the digital original.
