What is digital signing?

Digital signing, also known as electronic signature, refers to the process by which a person electronically agrees to the contents of a digital document or an electronic transaction. It provides a digital equivalent of a handwritten signature on paper and has the same legal value as a traditional signature.

Digital signing uses cryptographic techniques to ensure the integrity, authenticity and non-reproducibility of the signed document. It uses digital certificates, encryption and hashing algorithms to ensure that the document cannot be altered and that the identity of the signer can be verified.

There are several digital signing methods, including:

1. Digital signature: This is a specific form of electronic signature where a unique digital code is generated and added to the document. This code is created using a private key associated with the signer. Verifying the digital signature requires the use of the associated public key.

2. Biometric Signature: In this case, a person's signature is captured using a biometric device, such as a touchscreen or pen pad. The biometric data of the signature is then associated with the digital document.

3. Token-based signature: This uses a physical device, such as a smart card or USB token, that can generate and store a digital signature. The device contains the signer's private key and is used to place the signature electronically.

Digital signing offers several advantages over traditional paper signatures. It is faster, easier and does not require the physical presence of the parties involved. It also reduces the risk of forgery and provides better traceability and archiving of signed documents. In addition, digital signing can improve the efficiency of business processes, as documents can be exchanged and approved electronically without the need for physical copies.

The use of digital signatures is increasingly accepted and supported by laws and regulations in many countries around the world. It is important to note that the legal recognition of digital signatures may vary depending on the specific legal context and the country in which the signing takes place.
