The SignaturiX solution is based on the idea of an electronic handwritten signature, i.e. in addition to the features of an ordinary (graphic) signature,
it has biometric and graphical information to identify its authenticity.
signature is made on devices equipped with a touch screen and, depending on their type,
apart from the image of the signature itself, contains a number of parameters used in the analysis of authenticity.

  • “The total printing costs and operating costs associated with this area can consume up to 10% of the company's revenues...”
  • "According to the report prepared for OKI, 1/3 of European companies are planning to implement the electronic document flow in the near future."
  • "Time spent by employees related to document handling (processing, searching, updating) is about 10-20% of working time"



Thanks to the SignaturiX solution, we save on the costs of printing, sending and storing documents.


Advanced electronic signature compatible with eIDAS. Submission of a signature using SignaturiX is sufficient for written form.


Each signed document is protected against content change, signature replacement or unauthorized use.


Delivery, retrieval and archiving of signed documents is much faster than in the case of a paper version, and there will also never be any mistakes that may appear on the paper version.


By eliminating paper versions of documents we contribute to environmental protection.
Availability and convenience regardless of equipment
To use SignaturiX, the user does not need to install any additional software. All you need is a web browser and a connection to the SignaturiX server. As a result, almost every workstation (tablet, 2in1 device, smartphone, laptop computer or signpad computer) with appropriate technical parameters can instantly turn into a biometric document signing tool. Users do not have to download new software versions - they always work on one, current version.
Solution integrity
It guarantees that the content of every PDF document signed using SignaturiX is inseparably connected with the signatures it contains. The signature on the document contains a time stamp downloaded from the certified time server. The signature biometric is stored in an encrypted form inside the document and can be used for the graphical verification of the person submitting the signature.
Document security
The SignaturiX system is installed in the infrastructure of the Ordering Party. Unlike other solutions (based on the cloud solutions in particular), you can be sure that no document or sensitive data (biometrics of the signer included) leave your internal infrastructure at any stage of the process. SignaturiX software is a proprietary solution of Monolit IT – Polish engineers, programmers and IT security specialists.
Dedicated Customer Service functionality
The system provides functionality dedicatedo to customer service stations. With its help employee can display a digital document for signing without sharing the workstation’s screen to the client. Thanks to synchronization, content edition is visible on both devices, giving the possibility of cooperation on one document. The synchronization mode gives the employee full control over the document signing process without blocking the workstation.
Document editor
SignaturiX also has an extensive PDF document editor. Using it you can prepare forms or templates of documents completed and signed within the framework of electronic documents workflow.

What is SignaturiX?
SignaturiX is a system for handwritten electronic signature. The main purpose of the system is to reduce paper usage by replacing printed documents with their electronic form – a PDF file signed in accordance with ISO standard and PAdES (PDF Advanced Electronic Signatures). The signature is made with a stylus on a device equipped with a touch screen. Depending on the type of device, a set of unique characteristics for every person is saved. Those parameters can be used for the analysis of signature authenticity.
What is an electronic signature?
Within the meaning of eIDAS (Art. 3.10), ‘electronic signature’ means data in electronic form which is attached to or logically associated with other data in electronic form and which is used by the signatory to sign;. There are three types of electronic signatures: ordinary, advanced and qualified. An ordinary signature is merely a declaration of identity of the author made under a document in electronic form, for example name, surname, facsimile signature, etc.
What is and advanced electronic signature?
An advanced signature, thanks to the application of appropriate technical means, is additionally uniquely linked to the document and the signatory, which allows the identification of the signatory, and for any subsequent change of data to be detectable. A qualified signature is a special type of advanced signature, created using a qualified device and based on a qualified certificate.
Is SignaturiX a qualified signature?
SignaturiX is an advanced electronic signature that utilizes qualified trust services such as a qualified electronic seal and a qualified time stamp. As a result, it possesses almost all the advantages of a qualified signature, while being free of its limitations, such as the need for a prior issuance of a certificate and the use of qualified devices.
What is a biometric electronic signature?
It is an electronic signature in which the data used as a signature are linked to the biometric characteristics of the person making the signature, such as stylus position, signing speed, acceleration, pressure applied and their variation over time.
How does SignaturiX work?
SignaturiX is a server software installed in the client's infrastructure. Through SignaturiX API, internal domain systems send documents for signature. The system presents the document and optionally allows to fill it with additional information. After signing, the biometric data are encrypted and signed PDF file is created. It is signed with an electronic seal and a time stamp is placed. Everyone can verify the signature and integrity of the content at any place and time using popular free PDF viewing software, for example Adobe Reader. This way, any subsequent change in the document is easily detectable. In contrary to cloud-based solutions, documents never leave the customer's internal infrastructure.
What do I need to use SignaturiX?
Web browser and a touch device with a stylus (e.g. signpad, tablet, mobile phone or laptop) is enough for SignaturiX’s biometric signing. SignaturiX also enables signing without a stylus (signing with a finger or mouse). In this case, the collected biometric data are incomplete or the signature does not contain them at all, preserving only the image - an ordinary signature. SignaturiX software is installed on the server side of the client's infrastructure.
What security features does SignaturiX have?
SignaturiX has a number of security features to ensure that the document is integrally linked to the signature, and its content and biometric data of the signature do not fall into the wrong hands. Numerous security features include: protection against unauthorized access to the system, protection against unauthorized changes or substitution of the document displayed for signing, protection against CSRF attacks, protection against intercepting biometric data of the signature, protection against copying biometric data of the signature between documents, and cryptographic API protection for integration with other systems. Additionally, thanks to the provided security service, we guarantee a secure storage of the private key necessary to decrypt the biometric data. This key never leaves the hardware security module HSM (Hardware Security Module) where it has been generated.
Does SignaturiX automatically verify signatures online?
Due to security reasons, SignaturiX does not verify signatures online at the time of signing. The SignaturiX system does not store biometric data and is not capable of decrypting them.
Where is the biometric data stored?
Encrypted biometric data is stored only in the signed document (PDF file). Decrypting requires a key that is securely stored in the HSM (Hardware Security Module). Access to decrypted biometrics is restricted to persons authorized by the court in a given case, e.g. a court expert (graphologist).
What happens if the authenticity of the signature is questioned?
As an additional service, we safely generate and store the biometric decryption key. We also enable state authorities such as courts and court experts to use dedicated software for decryption and export of biometric data from a document, as well as software for analysing biometric signatures. This process is designed to ensure that Monolit IT does not process the analyzed documents or biometric data contained in them at any stage of the procedure. The private key necessary to decrypt the biometric data of the signature never leaves the HSM, therefore it is not transferred anywhere and is never compromised.
What kind of documents can I sign with SignaturiX?
SignaturiX allows you to sign any documents, contracts, consents or statements in PDF format. Before signing the document, the content of the file is presented to the user and after signing it, the content of the document is inseparably connected with this signature, which is additionally confirmed by a qualified certificate of an electronic seal. Documents signed biometrically and sealed with a qualified electronic seal retain full legal force and evidential value.
What is a written form?
This is a special documentary form specified in Article 78 § 1. "In order to maintain the written form of a legal act, it is sufficient to sign the document containing the content of the declaration of will by hand." Signature made with SignaturiX is sufficient for maintaining the written form.
