eSign API Compliance and Security in Accounting Operations

Accounting operations are required to deliver information to consumers in written form, which can be electronic if it aligns with the ESIGN Act’s guidelines. Under the ESIGN Act, consumers must provide their consent electronically in a manner that demonstrates their ability to access the information in the provided format. 

Financial institutions are advised to keep records of this consent process to comply with consumer laws and regulations. Failing to secure proper consent can significantly affect an accounting operation’s legal compliance.

Authentication and Identity Verification

  • Authentication options include biometrics or an OTP from the e-KYC provider.
  • Offers easy access to legally recognized digital signatures.
  • It complies with e-authentication guidelines and has secure signing processes handled by the eSign provider’s server.
  • Services are provided by licensed Certifying Authorities, ensuring trust and legality.
  • Enhances security by generating and deleting each user’s private key on a Hardware Security Module after one use.

Encryption and Data Protection Features

For encryption and decryption, the person who creates the digital signature uses a private key to encrypt signature-related data. The only way to decrypt that data is with the signer’s public key. 

If the recipient can’t open the document with the signer’s public key, that indicates there’s a problem with the document or the signature. This is how digital signatures are authenticated.

Regulatory Standards Supported by E-Signature API

For an electronic signature to be legally binding under the ESIGN Act, it is recommended that all electronic signature workflows include the following five elements:

  • Intent to sign,
  • Consent to do business electronically,
  • Opt-out clause,
  • Signed copies,
  • Record retention.
