The digital signature (or e-signature, eSignature, etc.) has become an indispensable tool for companies and individuals to manage documents in a more efficient and environmentally friendly way. In this article, we provide a starting point for anyone who wants to bring an old process - signing documents - up to date.
A digital signature is a secure and efficient method of signing contracts in a digital environment as an alternative to handwritten signatures.
The digital signature works like a human fingerprint, as each document has its own unique electronic fingerprint. No other document can have the same digital signature. If a digital document is "sealed" with a signature, it can be proven that
Digital signatures are already used in many industries for a wide variety of applications.
Only a signature that can also be verified by an approved online verification service (e.g. Acrobat Reader, RTR, or directly in sproof sign) can be classified as legally compliant.
A scanned image of a handwritten signature does not create a legally signed document and is not legally valid!
The eIDAS Regulation regulates for Europe how documents can be signed in a legally valid and verifiable manner. You can find out more here.
Applying a valid digital signature to a (PDF) document is a technically complex process that runs unobtrusively in the background when digitally signing a document.
A correct digital signature therefore differs significantly from simply inserting a scanned handwritten signature.
A valid digital signature allows subsequent changes to the document to be recognized. This is not the case when simply inserting images.
This is how digital proof of intent works with a signature platform:
First, you upload your document online via your account on a signature platform. The document is converted into a PDF document.
For the signature itself, you need a digital certificate that proves your identity as the signatory. This is created for you when you register on a signature platform. If you want to sign with the highest standard, the qualified electronic signature , this step is carried out by a state-recognized certification authority .
With a signature platform, you have the option of customizing your signature (similar to the handwritten version) and creating your own signature style.
In the final step, the entire contract, including the attached signatures, is cryptographically encrypted. A so-called hash value is generated. The contract becomes forgery-proof and verifiable.
The attached signatures have the highest probative value and can no longer be forged.
Of course, the signed contracts can be downloaded, sent or saved anywhere.
In principle, many file formats can also be digitally signed. However, in order for the applied digital signature to be unalterable, each document must first be converted into a PDF document. As is well known, PDF documents can no longer be changed (unlike docx documents, for example). Digital signature platforms automatically convert many file formats into a correct PDF document, usually when the document is uploaded.
There are various ways to obtain a digital signature.
As already explained, the creation of a digital signature is the central element of a digital signature platform. Established and well-known solutions are, for example, DocuSign , AdobeSign or newer European solutions such as sproof sign or yousign, which have also specialized specifically for use in European companies.
An advanced electronic signature is created for you when you register.
Many providers also equip users with a qualified electronic signature, which is deeply integrated into the application itself. In addition to the high evidentiary value of this signature standard, you benefit from the many options for customizing your signature process.
In Austria, more than 50% of citizens already have a cell phone signature. This is issued by public authorities and complies with the qualified electronic signature standard.
A valid contract is concluded when both parties express their consent. The legislator generally leaves it up to the contracting parties to decide whether they conclude a contract verbally, in writing or electronically. This is known as freedom of form.
If you opt for a digital signature solution, you have the advantage that all signatures are integrated into the PDF file in an unalterable and forgery-proof manner.
There are only very few exceptions where electronic signatures are still excluded by law, despite constant amendments to the law. One example: a will.
Either way, it is necessary to select the right e-signature standard depending on the contract.
Three standards have been established for this, which are defined in the eIDAS Regulation and serve as a legal framework.
The qualified electronic signature (QES) meets the highest quality criteria and is legally 100% equivalent to a handwritten signature.
As the legal implications can vary widely, factors such as implementation costs, ease of use (customer experience), legislation, company policies and the assessed business risk will usually determine which method should be used in a particular situation.
You can use the following decision guide to help you.
Two factors therefore influence the choice of the right standard for the electronic signature:
The advantages of a digital signature platform are that you can
European signature providers have mostly focused on the two highest digital signature standards.
sproof sign is an expert in the field of qualified electronic signatures (QES) in particular.
The term "scanned signature" means that it is a digital image of a handwritten signature. The original paper signature is converted into a digital format (.jpg, .doc, .pdf etc.) using a scanner or camera.
In principle, such scanned signatures are valid as long as no written form is required for the corresponding declaration of intent.
A signed copy is not legally valid as the signatory cannot be identified and consent cannot be proven.
A scanned signature is easy to forge so that the recipient of the signed contract can easily copy it (#SnippingTool #Screenshot). It is obvious that this is not legal.
A scanned signature has no probative value in court, as it is only a copy of your original signature. Without proof of how the signature was made, it is considered a mere copy and not an authentic signature. For this reason, it is invalid, especially in business transactions.
The terms "electronic signature" and "digital signature" can easily be confused. The terms are often used interchangeably, but strictly speaking they are not the same thing.
An electronic signature (or e-signature) is a method of concluding a legal agreement in a digital environment. It is, so to speak, the digital equivalent of signing a paper document.
While the electronic signature proves the consent of the signatory of the document, the digital signature is proof of the authenticity of the document itself. This means that the combination of document and signature has been technically designed and encrypted in such a way that the contract is forgery-proof. The terms thus merge or work together in such a way that a digital agreement becomes verifiable and legally enforceable.
