Combine the advantages of simple signatures with secure cryptography with proTECTr

Although the electronic signature represents a secure method for proving the origin of documents, it is not recognizable at first glance. Therefore, proTECTr always combines it with a simple signature that can be inserted into PDF documents. Alternatively, it is possible to initial individual pages with an abbreviation. This also makes it visually clear that the documents are electronically signed.

proTECTr signature forms

proTECTr offers a range of options for signing digitally. Which form is the right one is decided by the acceptance of the parties involved. Only if the written form is required, the qualified electronic signature must always be used.

To make the differences clear, the cryptographic forms of the electronic signature are separated conceptually:

Simple electronic signature

Simple & Quick to use

A simple signature is simple and quick to use. For example, it can consist of a textual name in an e-mail or a scanned signature. The simple electronic signature is the weakest form of signature because it can be executed without identity verification. This means that it cannot be clearly assigned to a person or the signatory. Therefore, this type of signature should only be used when there is a low legal risk, such as for the following documents:

  • General business relations
  • Documentation
  • Internal protocols
  • PDF with scanned signature

Advanced electronic signature

Clear assignment

The advanced electronic signature enables the signatory to be identified and is uniquely assigned to the signatory. It must be created with a unique, secret signature key to which only the holder has access. The advanced signature therefore offers a higher level of evidential value and security than the simple signature. Thus, this signature can be used for the following documents:

  • Data privacy statements
  • Permanent employment contracts (without digital evidence)
  • Insurance applications
  • SEPA mandates
  • Powers of attorney
  • Non-disclosure agreements

Qualified electronic signature

highest evidential value

The qualified electronic signature offers the highest evidential value for digital signatures and is thus equivalent to a handwritten signature. This level of security requires the identity of the person signing to be verified, for example via video or bank ident. After successful verification, a certified trust service provider creates an electronic certificate with the name of the signer. With this certificate and a signature creation device (QSCD), the signer can trigger a qualified signature.

The qualified signature can thus replace a handwritten signature and be used for documents where a written form requirement is necessary, such as:

  • Clause on the limitation of the term of employment contracts (fixed-term employment contracts)
  • Unlimited employment contracts (with digital evidence value)
  • Guarantees
  • Life insurance policies
