How to Share Digital Signature: A Complete Guide with Local Compliance Emphasis

In today’s digital-first world, digital signatures are transforming the way we sign and share documents. Whether you’re signing a contract, approving an invoice, or authorizing internal documentation, digital signatures provide a secure, legally-recognized, and efficient solution. However, for many users—especially in regions like Hong Kong and Southeast Asia—questions still remain about how to properly share a digital signature while complying with local electronic transaction laws.

This guide provides a comprehensive answer to the question: “How to share digital signature?” While ensuring your digital interactions are secure and fully compliant with regional regulations.

What Is a Digital Signature?

Before diving into the “how,” it’s important to clarify what a digital signature is. A digital signature is a form of electronic signature that uses encryption and public key infrastructure (PKI) to verify the integrity and authenticity of digital documents. Unlike basic electronic signatures (e.g., typing your name or inserting a scanned image), digital signatures meet stricter legal and technical standards.

In regions such as Hong Kong, digital signatures are recognized under the Electronic Transactions Ordinance (Cap. 553), which ensures that digitally signed documents have the same legal standing as handwritten ones, provided certain conditions are met.

📌 Note: In jurisdictions like Singapore, Malaysia, and Thailand, local laws such as the Electronic Transactions Act and their respective digital signature laws govern the use of digital signatures. Always ensure the service provider you use complies with these standards.

Step-by-Step: How to Share a Digital Signature

Here’s a simple step-by-step process for sharing a digital signature efficiently and securely.

Step 1: Create Your Digital Signature

You can generate a digital signature using a reputable digital signature provider. These platforms typically guide users through creating a verified signature using cryptographic techniques.

Some trusted providers include eSignGlobal, which offers regionalized options for users needing to comply with Hong Kong’s Electronic Transactions Ordinance or Southeast Asia’s equivalent regulations.

Step 2: Digitally Sign the Document

Once your digital signature is created:

• Upload the document to your chosen platform.
• Select the area where the signature should appear.
• Use the secure signing tools to affix your digital signature.
• Verify that the platform supports tamper-proof timestamping and audit trails.

Step 3: Encrypt and Secure the Signed Document

To protect your signed document before sharing, ensure it is encrypted. Most digital signing platforms automatically apply encryption and security protocols.

Platforms like eSignGlobal offer tamper-evidence technology, secure certificate authorities (CAs), and region-specific validation to meet both international and local digital compliance standards.

Step 4: Share via Secure Means

Depending on your workflow, you may use one of the following secure sharing methods:

• Email (Encrypted): Use secure email encryption tools like Outlook’s built-in encryption or G Suite.
• Cloud Storage: Services like Google Drive, Dropbox, or OneDrive—enabled with restricted access settings—are popular.
• E-signature Platforms: Sharing directly via platforms like eSignGlobal enables secure transmission and audits.

Step 5: Confirm Receipt and Authentication

Ensure the recipient can verify the signature using their own software or the same e-signature platform. Many services allow recipients to view verification details such as issuer, certificate chain, and timestamp.

This step is often required for documents that require compliance with Hong Kong’s Cap.553 or Singapore’s Cybersecurity Act.

What About Legal Validity?

One of the significant advantages of a digital signature is its legal recognition in many countries and regions. In Asia-Pacific, the following local regulations apply:

• Hong Kong: Electronic Transactions Ordinance (Cap. 553) supports digital signatures backed by recognized certificate authorities.
• Singapore: Recognized under the Electronic Transactions Act.
• Malaysia: Governed by the Digital Signature Act 1997.
• Thailand: Electronic Transactions Act B.E. 2544 (2001).

Ensuring your digital signature provider complies with these acts is vital for your signed documents to hold up in court or during audits.
