The term "eSignature" (electronic signature) is a broad concept encompassing all types of methods used to sign electronic documents. It serves as the digital counterpart to handwritten signatures and is used for authentication and legal assurance in electronic business processes. There are different levels of eSignatures, each varying in security and legal validity:
The digital signature is a technical implementation of AES or QES, using cryptographic methods (such as asymmetric encryption) to ensure document authenticity and integrity.
Document Upload: Providing documents for electronic signing in formats like PDF or DOCX.
Signature Generation: Applying the desired type of signature (simple, advanced, qualified).
Identity Verification: Integration of verification methods (e.g., eID, VideoIdent, SMS-TAN), depending on the required level.
Digital Signature Technology: Using cryptographic methods to generate and validate signatures.
Multi-step Signing Workflows: Supporting signature sequences involving multiple signers across locations.
Timestamping: Legally valid logging of the exact time of signature.
Integrity Checks: Ensuring that signed documents remain unchanged after signing.
Compliant Archiving: Tamper-proof storage and audit trail of all signing activities.
System Integration: API-based connectivity with ERP, CRM, DMS, or contract management systems.
Notifications & Reminders: Automated alerts about pending or completed signing processes.
A software company has project contracts signed by customers using a qualified eSignature.
An HR team sends employment contracts electronically for signing with identity verification.
A supplier agreement is signed in a digital, multi-party workflow.
A managing director uses a signature platform with timestamping to legally approve annual reports.
An integrated CRM system automatically triggers signature requests for new customer agreements.
