Digital Signing systems

Solutions > Digital Signing systems

All of us realize the Green Revolution, which is mentioned everywhere. Technological developments cause public outlook changes, and what in the past seemed impossible can easily be done today.
The quantity of paper that we produce/receive daily is excessive, the effort and occupation surrounding paper is a burden and very expensive to all sectors.

Legislation of the Electronic Signature Law, 5761-2001 allows us to send and receive most of the current documents that we are familiar with directly to electronic mailboxes, and instead of filing them in folders and storing them in boxes, they can be digitally signed and stored in a digital archive, and thus save endless time, money and resources.
In accordance with streamlining the organizations and institutions, and according to the public’s needs, Comda, in cooperation with its subsidiary ComSign – the certificate authority (CA), has developed the ComsignTrust system. This system is built on the basis of the PKI infrastructure, is designated to electronically sending files signed by authorized electronic signature, as well as signing an organization’s existing files and storing them in secure electronic archives.

ComsignTrust exclusive added value, which differentiates it from other similar systems in the market, is the quality of its components which fully comply with the Electronic Signature Law and the legal demands for the signing methods which are required for the authorized signature (received legal admissibility), which are supplied to a system by ComSign – the CA. Its uniqueness is that the document signed by an authorized electronic signature is guaranteed as secure and cannot be forged, and accordingly, it is accepted as a legal original document.

Many enterprises have adopted the Comsign Trust solution, applying it and streamline themselves, both financially and image-wise. For example, the cellular phone companies offer their customers the option to receive their monthly invoices by email instead of regular mail. 

E-Sealing Advantages:

 Convenience in sending and receiving signed documents.
 Paper use reduction.
 Absolute protection of the document’s accuracy (cannot be changed after signature).
 Absolute signatory authentication, without the possibility of forgery.
 Quick document delivery.
 Significant financial saving.

Our electronic signature application system allows applying electronic signing to information files in various formats, and in this way achieving the following:

 Creating trust in the document producer and sender’s identity, and that of the person who authorized the information (performed by each position holder signing electronically)
 Protecting the document’s completeness – preventing unknown changes and authorizing information (performed by electronic signing)
 Creating trust in the time that the document was signed (performed by an electronic signing)
 Protecting the information secrecy and preventing information leakage to unauthorized entities (performed by encryption)
 Protecting information access and change rights (by Office document access and change rights management tools)

The system includes a number of built-in solutions in order to implement the aforementioned requirements. Among them are:

 Increased protection of Windows or Unix files – creating a protected container that allows electronic signing, information about the signing time, organizational authorization management and encryption
 Increased protection to PDF and Office documents – adding abilities to implement organizational authorization regulations, information and encryption reading/changing permission
 Increased protection for all applications based on a Web, Microsoft or CAPI server.

Creating long-term “evidence” by creating an archive for files and libraries

Organizations are required to create “evidence” of the credibility of various types of information, whether in order to adhere to official laws and regulations, or for internal organizational requirements.

The system’s solution is the simple user-friendly ability to perform electronic signing and encryption of a file in any format (including data and picture files, such as TIFF). After signing, an archive document is received, resembling a ZIP file, which can be checked and the identity of the users involved in creating, changing and authorizing the file can be verified. In addition, encryption and information about the time the document was created and changed can also be integrated.

Protection for PDF documents, as well as Word and Excel forms

The existing ability to perform transactions between different organizations electronically is blocked by legal and regulator obstructions. This prevents many organizations from signing contracts, price quotes, invoices, various types of report, etc. electronically.
There is a need for technological tools which allow authenticating information reliability and completeness, and preventing denial. Remember that these documents must be kept for a very long time. Therefore, authentication ability should also be ensured years after signing.
The solution contains an applicative plug-in with the ability to sign PDF documents, as well as Word and Excel forms. The outcome is a visual symbol showing that electronic signing was performed, which can be checked easily. A number of signatures can be applied to the same document/form, signing which includes the signature time can be performed, and the organization’s logo or personal signature samples can be integrated.

Adding the ability to implement authorization to read/change Office documents

Almost all organizations worldwide are based on Office documents for creating and distributing organizational information, some of which is defined as extremely sensitive. Sensitive document creators would generally like very much to limiting those who can see the information in the document.
In addition, there is a need to prevent the ability of these entities to change the document, print it, cut and paste information contained in it and even prevent the ability to open the document after a certain date.
Comda’s electronic signature application system contains exclusive options to protect an original document that can be accessed within or outside the organization. The document will continue to look like a regular Office document, but authentication of the entities accessing it will be performed (by integration with the organizational active directory, using a password, electronic certificate, etc.). Document encryption is performed by a 256-bit AES algorithm. After encryption, changing, printing, cutting and pasting, opening after a certain time, etc. can be prevented.

Advanced user authentication ability

Using digital certificates requires the ability to check it at any stage and during any procedure.
The digital signature solution contains an advanced designated plug-in for Windows operating systems and applications, for immediately checking using CRL or OCSP. This component can be installed simply and the user interface is via a small balloon window, which contains the information regarding the certificate validity. This solution is Identrus certified and supports CAPI based applications.

Advanced protection server for services and applications requiring electronic signatures

When transferring data files, in certain cases a central server is required. This central server must contain Web-based user access ability, as well as standard access which organization users are familiar with.

The solution contains an advanced protection server, which allows central file signing, and sending them to external entities as email messages or HTTP pages.

This system provides a perfect solution and is tailored according to the customer’s needs.
