What is a Public Digital Signature? Should It Replace Handwritten Signatures?

The boom in demand for cross-border transactions, coupled with the rise of electronic transactions, is encouraging many managers to use public digital signatures instead of traditional handwritten ones. Especially as digitalization and technology increasingly dominate every aspect of life, public digital signatures have become a crucial and necessary part of a business’s electronic signing activities. So, what is a public digital signature? Is it recognized by the state? What is the registration procedure? 1Office will help you answer all these questions in the article below.

What is a public digital signature?

According to Decree No. 26/2007/ND-CP, Article 3, Clause 8, the definition of a public digital signature is clearly stated: “A public digital signature is a digital signature created by a subscriber using a digital certificate issued to the subscriber by a public digital signature certification service provider.”  

Simply put, a public digital signature is a type of digital signature that uses a USB token provided by a digital certification service provider for an individual to prove the authenticity of an electronic message or document. 

A public digital signature is created and distributed through a digital signature management system, which uses a key pair, consisting of a private key and a public key. The private key is kept secret and used only for signing and decrypting, while the public key is made publicly available to verify the signature. When a document is signed with the private key, the recipient can use the public key to verify the authenticity of that signature, ensuring that the message has not been altered during transmission.

Legal validity of public digital signatures

Public digital signatures licensed by the Ministry of Information and Communications are legally guaranteed and protected by law. By using encryption technology that ensures a high level of security, this digital signature represents the individual and has the same validity as their handwritten signature.

A public digital signature certificate issued by a service provider licensed by the Ministry of Information and Communications allows users to apply them in signing various transactions and different types of contracts, such as labor contracts, commercial contracts, service contracts, etc. In the event of a dispute, the digital signature user’s rights will be protected by the legal system, provided they comply with legal regulations when conducting the transaction.

Why should businesses use public digital signatures?

Amid the trend of digitizing administrative procedures, businesses need to quickly adopt new technologies to optimize operational efficiency by streamlining traditional paperwork. Besides convenience and time savings, digital signatures also play an important role in:

Supporting online tax declaration activities

Most tax declaration and payment procedures can now be conveniently performed online. However, to carry out these transactions, businesses need to use a digital signature registered with the tax authorities. By using a digital signature, all tax-related transactions become simpler and more secure.

Simplifying the contract signing process

When signing electronic contracts, all parties involved need to confirm the agreement with a digital signature. Businesses using digital signatures can easily sign a large number of contracts, helping to save costs and shorten the process time.

Saving budget, time, and money

Businesses no longer need to invest heavily in personnel when integrating public digital signatures into their contract signing and tax transaction processes. Printing costs are significantly reduced, and implementation time is also shortened.

Ensuring legal validity

A public digital signature is considered to have a value equivalent to a handwritten signature and the company’s seal. Signing electronic documents with this type of signature not only ensures legal validity but also helps protect the rights of all parties involved.

Data security

The security of a digital signature is significantly higher because it can ensure a closed data information system, helping to secure all transactions and documents. A digital signature helps prevent fraud and signature forgery, and it can also serve as evidence in case of a dispute between two parties.

Aligning with international integration trends

In the context of global economic integration and the digitalization of all business aspects, the public digital signature is an important and useful tool that helps businesses adapt to this trend. Using digital signatures to sign contracts remotely will help businesses be more flexible in their business cooperation processes and have more opportunities for development with foreign partners.
