The client needed a tool that would enable the electronic signing of documents for all parties involved at CPK.

As SOFTIQ, we acted as a subcontractor in collaboration with EUVIC. We created part of the system for a wider range of changes.

The biggest challenge was to develop a tool that was simple and intuitive to use. A solution had to be developed that works efficiently with 250 users working simultaneously and can process 30 Mb files. The application works by specifying a list of people and defining the order in which they should sign documents. Multiple documents can be signed within a single workflow. Both a non-qualified signature issued by an internal authorisation authority and a qualified signature can be used for signing. The DSS (Digital Signature Service (europa.eu)) component was used for this purpose.

The system is designed for four users:

• System administrators - system administration functions
• Coordinators - defining and managing document circulation
• Internal users - persons directly related to the CPK who are able to submit and initial the circulation documents with qualified and non-qualified signatures
• External users - contractors and all other CPK stakeholders. These persons can only use a qualified signature.

System administrators, coordinators and internal users have access to the internal application, which is integrated into CPK's Active Directory system.
External users use a publicly accessible external application to which they are given temporary access by receiving an email with an access link.
We have used open source technologies and a DSS component to build the system.

The project was carried out according to the waterfall method in standard phases:

• Phase I: Analysis
• Phase II: Project
• Phase III: Implementation
• Phase IV: Test
• Phase V: Implementation and workshops

The project lasted 6 months, of which the analysis phase took about 6 weeks. A detailed prototype of the system was then developed together with the customer

SignFlow supports CPK in its daily work, which involves a large number of documents in such a large organisation. The tool, which supports the electronic signing of documents, has an impact on the efficiency of the organisation's work, shortens the processing time and significantly reduces costs.
