Digital Signatures (CoSign) Solution

Digital signatures

Digital signature solutions produce legally enforceable electronic records, closing the gap towards going fully paperless by completely eliminating the need to print documents for signing. Digital (secure, electronic) signatures enable the replacement of slow and expensive paper-based approval processes with a fast, low-cost, and completely automated process. By enabling a fully automated workflow, digital signatures reduce the expense and time that paper-based signatures require.

Digital Signature Technology

The system uses the following components:
  • Signer’s Identity: the signer’s ID is embedded in the signed document.
  • Signer’s Intent: a combination of 2nd ID-challenge and Reason Code.
  • Document Integrity: Data cannot be changed without being invalidated.

Key Benefits

Expedite Processes: speed up business processes by eliminating slow, paper-based approvals.

Reduce Costs: associated with printing, scanning, archiving, routing and replacing lost documents.

Industry and Legal Compliance: specifically designed to protect document integrity, the CoSign digital signature solution assists in compliance with numerous regulations including ESIGN, EU directives and VAT law, HIPAA (and JCAHO), the FDA’S 21 CFR Part 11, USDA, and the Sarbanes-Oxley Act. The solution allows personal as well as organisational reporting.

Seal Document: CoSign's design ensures that anyone can verify the signature and content integrity of a signed document anywhere, at any time, with a simple click – and it allows multiple signatures to be placed on a document (one after another) while maintaining the document’s integrity. In addition, its reporting capability is in line with audit requirements.

Go Green: Digital signature solutions save a considerable amount in paper and emissions by enabling organisations to go completely paperless. Trees are saved by eliminating the need for paper-based processes such as faxing, printing, scanning and archiving. Emissions are reduced by eradicating the need to ship documents by land or by air.
