There are mainly three types of electronic signatures. • Simple Electronic Signature (SES) • Advanced Electronic Signature (AES) • Qualified Electronic Signature (QES) Simple Electronic Signature (SES) A SES is the most basic form of digital signature, where a signature is created using an electronic means such as typing in a name or clicking a button to indicate acceptance of terms. SES does not use encryption or any advanced security mechanisms to protect the authenticity and integrity of the document. Advanced Electronic Signature (AES) An AES is a digital signature that meets certain legal requirements to be considered equivalent to a physical signature. It is created using cryptographic techniques to ensure the integrity and authenticity of the signed document. Esignature also provides non-repudiation, meaning the signer cannot deny having signed the document. Qualified Electronic Signature (QES) A QES is the highest level of digital signature that meets the strictest legal requirements for electronic signatures. It is created using a secure signature creation device (SSCD) that is certified by a trusted authority. QES provides the highest level of security, integrity, and authenticity, and is legally equivalent to a handwritten signature. Electronic signature is a convenient and efficient way to sign documents electronically. The type of electronic signature that you choose depends on the level of security and authenticity that you require. Simple electronic signatures are easy to use but are less secure than advanced electronic signatures, while qualified electronic signatures provide the highest level of security and are legally equivalent to a handwritten signature. Biometric signatures are the most secure type of electronic signature, but they require special hardware and may not be practical for all types of documents.
