![]() To protect the integrity of the signature, PKI requires that the keys be created, conducted, and saved in a secure manner, and If the public key can’t decrypt the signature (via the cipherįrom which the keys were created), it means the signature isn’t Jane’s, or has been changed since it was signed. Receives the document also receives a copy of Jane’s public key. If the document changes after signing, the digital signature is invalidated.Īs an example, Jane signs an agreement to sell a timeshare using her private key. Marked with the time that the document was signed. The resulting encrypted data is the digital signature. ![]() The mathematical algorithm acts like a cipher, creating data matching the signed document,Ĭalled a hash, and encrypting that data. ![]() When a signer electronically signs a document, the signature is created using the signer’s private key, which is always One key is public, and one key is private. To use a mathematical algorithm to generate two long numbers, called keys. Such as DocuSign, follow a specific protocol called Public Key Infrastructure, or In addition, some industries also support specific standards that are based on digitalĭigital signatures, like handwritten signatures, are unique to each signer. Regulation, there are two levels of digital signatures: Advanced Electronic Signature (AES) and Qualified Electronic Technology, including many countries in the European Union, South America, and Asia. In particular, the use of digital signature technology for e-signatures varies significantly between countries thatįollow open, technology-neutral e-signature laws, including the United States, United Kingdom, Canada, and Australia,Īnd those that follow tiered eSignature models that prefer locally defined standards that are based on digital signature However, there are differences in purpose, technical implementation, geographical use, andĪcceptance of digital signatures versus other types of e-signatures. The category includes digital signatures, which are a specific technology implementation of electronic signatures.īoth digital signatures and other e-signature solutions allow you to sign documents and authenticate the signer. The broad category of electronic signatures (e-signatures) encompasses many types of electronic signatures. What’s the difference between a digital signature and an electronic signature?Ī digital signature is a type of electronic signature that requires a more rigorous level of identity assurance
