YOUR REQUIREMENTS

The most important aspect when selecting a signature solution and provider is your requirements, which can include:
  • What legal value do you want your signed documents to have?
  • Should all signed documents have the same legal value?
  • Do you want to integrate with your existing Business Applications?
  • Which cost per signature is acceptable?
  • How can your signatories practically be identified?
  • How securely are your signatories identified?
  • Is the data to be signed strictly confidential or very sensitive?
  • etc.
There are a number aspects that needs to be considered and most organisations have different requirements. Comfact can assist you in investigating how your specific requirements can be fulfilled - contact us.

A SIGNATURE

Signature services normally provide similar results in a digitally signed document according to a signature format. The eIDAS Regulation defines a number of signature formats such as XAdES-LT, PAdES-LTA, CAdES-B, etc. and there are 13 available formats. These formats are very technical and the only difference between them is how the PKI digital signature is packaged.

You normally do not need to decide on which signature format to use, but you need to decide on the types of documents that you accept e.g. PDF or XML.

An aspect that you must consider carefully is that of how a signer has been identified and authenticated in order to be authorized to sign.

LEGAL SUSTAINABILITY

Different solutions provide various levels of legal sustainability when evaluating who signed what, how, and when. It is important to choose the solution that provides the required level of legal sustainability.

Important aspects to consider when choosing a solution are that the signature:

  • uniquely identifies the signatory (who)
  • exactly defines the information that is signed (what)
  • clearly provides the intent of the signatory (why)
  • states how the signature was created (how)

LEVELS OF ASSURANCE

Comfact provides different alternatives in our signature services in order to fulfill customers’ requirements. It is possible to use different levels of sustainability for different types of documents so that, for example, documents with a higher importance are signed with a stronger signature.


One important aspect of selecting a signature service is assigning a degree of confidence in a claimed identity. For example, eIDAS includes three levels of assurance: High, Substantial, and Low. The following examples show how currently available identities map to these levels.


How do you choose which level of assurance you want to use? It is basically for you to decide which probative value you want your signatures to have. A High level provides a high probative value whereas a Low level has a low probative value.

INFORMATION SECURITY
Confidentiality
Unauthorized disclosure of information during a signature process can have serious effects on the involved parties. Comfact Signature has been designed to protect customers’ information from unauthorized disclosure.
Integrity
Comfact Signature is designed to prevent the unauthorized modification or destruction of information. Any modification of information during the signature process is restricted and only allowed under certain circumstances.
Availability
Comfact Signature is developed to provide very high availability. Many of the underlying services, such as sending email and SMS messages as well as timestamps have more than two separate alternatives. Comfact IT infrastructure is also redundant to ensure high availability
