With proTECTr you can create legally valid and EU-wide recognized qualified1 electronic signatures as a replacement for your handwritten signature directly in the browser. Sign important documents conveniently with a click of the mouse and without an additional signature card or card reader.
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 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:

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:
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:
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:
