Biometric Signature

Biometric signature is an electronic signature method used to sign documents using a special device, i.e. a tablet with a digital pen. This signature captures graphometric data including signing speed, pressure and pen movement angles.

This data is unique to each person and forms a biometric profile that helps ensuring the authenticity of the signature.

A biometric signature is a handwritten signature on a device screen that captures unique signing data, such as pressure and speed. In contrast, an electronic signature is a digital signature created using encryption and linked to a certificate.

A biometric signature visually resembles a handwritten signature but in digital form, whereas an electronic signature is typically invisible and verified through a system.

Electronic signatures are ideal for remote signing, while biometric signatures are used in physical environments, such as customer service locations.

Biometric signatures include a variety of methods to verify person’s identity using unique physical or behavioural traits such as fingerprints, facial recognition, voice recognition and graphometric analysis of writing movements.

Graphometric signature is a specific technology that captures dynamic data from handwritten signatures, such as pen tilt angles, pressure and accelerations.

Although it may not be technically accurate to apply the term “biometric signature” to a graphometric signature, Elpako uses the term because of its easy recognition and clarity.

It is important to note that Elpako’s biometric signature is, in fact, a writing motion analysis that captures graphometric data. This allows a more effective delivery of this technology to the users and to ensure its clarity.

Template creation is a useful feature enabling you to quickly and easily prepare documents that can be filled in by customers when they come for a live service. Document templates can completely replace all paper documents.

Templates ensure:

  • Time-saving: once created, a template can be used many times.
  • Consistency: all documents have the same format and structure.
  • Flexibility: the fillable fields can be easily moved around and customised, as needed.

Templates are created using a drag-and-drop feature and include:

  • Text
  • Numbers
  • Email address
  • Date
  • Selecting from a dropdown list
  • Radio button
  • Checkbox
  • A picture (e.g. a photograph of a personal identification document or an additional document taken with a tablet)

This facilitates managing of your documents efficiently and ensures their smooth completion.

Assistance mode are tools that help both the administrator and the client to work on the same document at the same time but on different screens. This means that the administrator and the client can see and complete the same document at the same time, but on their own screens.

These features also include a wizard animation that helps the client understand how to fill out the document correctly. The wizard guides the client through the fill-in process, indicating what information needs to be entered and ensuring that everything is done correctly and smoothly.

The assistance mode are very useful in avoiding errors and ensuring that all data is entered correctly.

The Elpako platform works on all tablets with an electronic stylus that support Android, Windows, iOS or Linux operating systems. The manufacturer or technical specifications of the tablet doesn’t really matter, as long as it meets the above criteria and can connect to the internet.

Qualified electronic signature

Electronic signature is a legally valid means of signing and electronic identification of a legal or natural person governed by the laws of the Republic of Lithuania. Documents signed with an electronic signature bear the same legal standing as paper documents signed in the traditional (handwritten) manner.

It is widely used for signing various electronic documents (letters, contracts), connecting to electronic government gateways, banks or electronic service systems of other institutions.

The legal regulation of all electronic signatures, electronic seals and timestamps is laid down in the Regulation (EU) No 910/2014 of the European Parliament and of the Council on electronic identification and trust services for electronic transactions in the internal market (hereinafter referred to as the eIDAS Regulation).

The legal regulation of eIDAS in Lithuania is also regulated by the Law on Electronic Identification and Trust Services for Electronic Transactions, which regulates the legal effect of electronic signature, electronic seal, electronic timestamp and trust services, obligations of trust service providers and users, terms of and procedure for suspension and revocation of qualified certificates for electronic signature, electronic seal or certificates for website authentication, and supervision of trust service providers.

Qualified electronic signatures are considered to be the ultimate security tool.

Only official providers on the EU trust services list can issue a qualified electronic signature certificate. A document signed with a qualified e-signature has the same legal standing as a hand-signed document. The regulation and legislation regulating this signature is the uniform across the EU, while compliance at national level is supervised and enforced by each EU country independently.

In Elpako, documents can only be signed with a qualified electronic signature, which has the same legal effect as a handwritten paper document. It is important to note that the requirements for a qualified electronic signature are identical in all EU countries, therefore, documents signed in Elpako are legally valid not only in Lithuania, but also throughout the European Union.

Elpako’s qualified electronic signature ensures the highest data security. This electronic signature is fully compliant with the trust measures listed in the European Union’s list of trust service providers. The security of the signature is also guaranteed by a surety bond issued by an insurance company.

In Lithuania, electronic signatures are already considered an indispensable part of personal and professional comfort by natural and legal persons.

Electronic documents signed at the touch of a button create a new user experience and allow unrestricted access to all the benefits of the digital space.

It also actively contributes to the conservation of natural resources by eliminating paper documents and saving time spent travelling to exchange documents.

Signing up takes just a few minutes and is very simple:

1. Verify your identity with Smart-ID, Mobile-ID (m-signature), USB stick or ID card. Confirm your e-mail address when you register.

2. Upload the document you want and sign with a qualified electronic signature with: Smart-ID, Mobile-ID (m-signature), USB stick or ID card.

Done! Your documents are signed!

Elpako works with ADOC, PDF, PDF-LT and ASiC specification documents that can be signed with a qualified electronic signature.

The most universal and popular format is PDF, which is recognised throughout the European Union.

ADOC is an electronic repository or container for electronically signed electronic documents. After signing, the Elpako user can download the signed document. Documents signed in Elpako (for example, a contract or an application) take the extension “.adoc”, i.e., a container containing the signed documents, the data related to the document and the e-signature.

The ADOC format is convenient in that the user can place files of different formats in this container, such as .docx, .xlsx, .pptx, .ppsx, .odp, ; .pdf” .tif., .tiff, .jpg, .jpeg, jfif, .png, .odt, and.ods.

The ADOC format is widely used in Lithuanian public sector institutions, as it meets the requirements of the Specification of Electronic Documents Signed by Electronic Signature ADOC-V1.0 approved by the Department of Archives under the Government of the Republic of Lithuania. The documents drawn up in Elpako fully meet these requirements.

Signing documents in ADOC is fast, convenient and efficient. Elpako makes it possible for users to view ADOC documents and e-signature data that can be verified in real time.

The ASiC document format is an electronic document format used in other European Union countries. This type of document, just like the ADOC, can contain multiple files that are signed. When preparing this type of document, it should be verified whether the recipient will be able to accept this type of document, as not all parties are able to read and handle these document types.

The FOR INDIVIDUALS plan is designed for a single user (for personal or work-related needs).

The FOR TEAMS plan is intended for more than one user. Team members can share, sign and check documents among themselves. They can also assign the right to manage and catalogue documents.

This error appears when a document is sent to an email address that doesn’t match the one you’re logged into on https://app.elpako.lt.

When the sender initiates the signing process, the system immediately indicates whether the recipient is registered on the Elpako platform:

  • If only the email address is shown, the user is either not registered or the address is incorrect.

  • If the full name appears in uppercase letters, the user is registered and the signing process will proceed successfully.

If you received the document for signing:

Contact the sender and ask them to resend the document using the same email address you used to log in to the Elpako platform.

If you initiated the signing process yourself:

  1. Go to “My Documents.”

  2. Open the document and remove the incorrect email address (three dots → “Remove”).

  3. Enter the correct email address – the one registered to the recipient’s Elpako account.

  4. Re-initiate the signing process.

When the system recognizes the user, their name will appear in uppercase letters in the invitation – this confirms that everything is set up correctly and signing will be successful.

Still seeing the same error message?

If you still receive the message “The email address in the invitation does not match your Elpako login,” even after entering the correct email, follow these steps:

  1. The sender (or you, if you initiated the signing) must delete the existing document.
    This clears outdated data that might be interfering with the signing process.

  2. Start a new signing process and ensure the correct email address is used – the one the recipient is logged into at https://app.elpako.lt.

  3. Confirm that the recipient is registered in the system and that their name appears in uppercase letters in the invitation – this confirms successful recognition by the system.

Once these steps are completed, the signing process should proceed smoothly.
