Digital signatures are like electronic “fingerprints.” In the form of a coded message, the digital signature securely associates a signer with a document in a recorded transaction. Digital signatures use a standard, accepted format, called Public Key Infrastructure (PKI), to provide the highest levels of security and universal acceptance. They are a specific signature technology implementation of electronic signature (eSignature).

Digital signatures, like handwritten signatures, are unique to each signer. Digital signature solution providers, such as DocuSign, follow a specific protocol, called PKI. PKI requires the provider to use a mathematical algorithm to generate two long numbers, called keys. One key is public, and one key is private.

When a signer electronically signs a document, the signature is created using the signer’s private key, which is always securely kept by the signer. The mathematical algorithm acts like a cipher, creating data matching the signed document, called a hash, and encrypting that data. The resulting encrypted data is the digital signature. The signature is also marked with the time that the document was signed. If the document changes after signing, the digital signature is invalidated.

As an example, Jane signs an agreement to sell a timeshare using her private key. The buyer receives the document. The buyer who receives the document also receives a copy of Jane’s public key. If the public key can’t decrypt the signature (via the cipher from which the keys were created), it means the signature isn’t Jane’s, or has been changed since it was signed. The signature is then considered invalid.

To protect the integrity of the signature, PKI requires that the keys be created, conducted, and saved in a secure manner, and often requires the services of a reliable Certificate Authority (CA). Digital signature providers, like DocuSign, meet PKI requirements for safe digital signing.

What’s the difference between a digital signature and an electronic signature?

The broad category of electronic signatures (eSignatures) encompasses many types of electronic signatures. The category includes digital signatures, which are a specific technology implementation of electronic signatures. Both digital signatures and other eSignature solutions allow you to sign documents and authenticate the signer. However, there are differences in purpose, technical implementation, geographical use, and legal and cultural acceptance of digital signatures versus other types of eSignatures.

In particular, the use of digital signature technology for eSignatures varies significantly between countries that follow open, technology-neutral eSignature laws, including the United States, United Kingdom, Canada, and Australia, and those that follow tiered eSignature models that prefer locally defined standards that are based on digital signature technology, including many countries in the European Union, South America, and Asia. In addition, some industries also support specific standards that are based on digital signature technology.

How to create an electronic signature in Word

Most individuals and organizations use Word to create documents. Given the platform’s global popularity, the e-signature has become a more efficient form of getting approval and verification compared to wet ink signatures. Electronic signatures remove the requisite to print and send hardcopies before getting approvals.

Creating electronic signatures in Word is easy and can be applied in version 2007 up to the latest version, Office 365. Follow these steps to create e-signatures in Word:

Place the cursor on your desired signature line or location.

Go to the Insert Tab and click on “Signature Line.” Other versions of Word may require you to click “Signature List” under Text.

Complete the necessary details such as Suggested Signer and Title. The signature line will appear.

Right-click on the signature line and click “Sign.” You may:

Select the image of your chosen signature;

Type a printed version of the signature;

Or draw a signature in a touchscreen device.

While electronic signatures promote efficiency and convenience in verifying documents and maintaining legal binding, the security and integrity of the document can still be questioned as validation is not performed on those signatures. These challenges are addressed by digital signatures.

6 steps to create a scanned digital signature

There are multiple ways you can go about creating a scanned digital signature, and it doesn’t have to be difficult or time-consuming.

Here are six steps you can take to create a scanned digital signature.

1. Sign the document

The first step is to simply sign a piece of paper with your handwritten signature. It’s a good idea to make the signature larger than you normally would because the digital format will likely shrink down. It’s also a good idea to create several signatures, so you have a few to choose from.

2. Scan the document

Once you’ve signed the piece of paper, you can scan the document. You’ll want to pay attention to the document resolution, or DPI.

Scanned images with a higher DPI will look more realistic, so it’s a good idea to choose a DPI of 600 or higher. You should always aim to have too many pixels as opposed to too few because this will help preserve the quality of the image.

3. Crop the image

Once you’ve scanned the signature and chosen the one that you think looks best, you’ll want to crop the image.

You may also need to adjust and move the signature so that it’s level on a horizontal signature line.

4. Paste the image in a new document

Once you’ve cropped the image of your signature, you can save it in a new document with a transparent background. You can edit the image file with a magic wand to remove any white that is still inside the document.

5. Save the file as a PNG

Next, you’ll want to save the file as a PNG. If the signature is saved as a PNG, it can easily be uploaded into most eSignature software. PNG files support transparency which makes them good for text and drawings. And it will protect the quality of the image better than JPG files.

6. Use the signature on contracts and documents

Now that you’ve saved the scanned digital signature, it will always be available for you to upload to contracts and other documents. This will help you sign documents and close deals faster.

Some people also like to add their scanned digital signature to their email signature for a more personal touch. Just make sure you send a few test emails so you know it looks the way you want it to.

Conclusion

A digital signature is a form of an electronic signature. It has a solid foundation and legally it is the same as a handwritten signature. The process also comes with several benefits, starting from cost-cutting to time-saving. It is simply designed to reduce labor while improving the infrastructure at the same. It is much more likely that sectors like healthcare, legal departments, military, financial sectors are using digital signatures and they are benefitting from it. So, it is wise for any organization to use an efficient digital signature from providers like MSBDocs.

The MSB Docs – Digital Signature implementation is simple, cost-effective, and will provide an additional level of security for any signed document. With the use of MSBDocs digital signature software workflow will get better and enhance the safety and revenue at the same time.
