Adobe Acrobat Sign FAQ (original) (raw)
Types of electronic signatures and seals available from Adobe include:
- Basic signatures - A basic signature is the simplest form of an electronic signature where the signer is primarily identified via an e-mail address. This type of signature may also include some additional signer authentication such as a one-time password (OTP) sent to a mobile phone. Basic signatures may be created by typing a name in a signature field, using an image of a handwritten signature, or by drawing on a touch screen.
- Verified signatures - A verified signature is an electronic signature that is created after the signer’s identity is verified or re-confirmed by a trusted 3rd party during the signing process. Verified signatures may include a wide range of identification experiences and levels of assurance (LoA), but all require the signer to engage with an identity provider (IdP) such as a bank, government, or other identity provider. Verified signatures are supported by a Signer Identification Report (SIR), which includes details from the IdP on a successful signer identification.
- Digital signatures - A digital signature is a more secure electronic signature that is generated using a digital certificate and cryptographically bound to the document using public key infrastructure (PKI). The digital certificate is unique to the signer and obtained from a trusted 3rd party such as a trust service provider (TSP) or certificate authority (CA) after verification of the signer’s identity.
- Cloud signatures - A cloud signature is a digital signature where the signer’s digital certificate is managed by a trust service provider (TSP) in the cloud. Cloud signatures rely on the global open standard created by the Cloud Signature Consortium (CSC). Compared to a traditional digital signature applied using a physical smart card or USB token, a cloud signature makes it easy to apply trusted digital signatures directly from a mobile device or a Web browser.
- Electronic seal - An electronic seal or e-seal is used by a legal entity such as a business or organization to certify the origin, authenticity, and integrity of documents. Electronic seals may provide strong legal evidence that the document has not been altered and originated from the entity identified by the digital sealing certificate.
