Projects

1. Reporting features for the application UserBooster Professional

Projected and developed a module for adding build-in and custom reporting capability to the UserBooster Professional product of maxcrc GmbH.

Designed a reporting module to be able to offer build-in reporting system, capability to extend the reporting capabilities without changing the main software. Also a background function, scheduled by a Windows Service allows the user to repeatly generate the reports, on a scheduled basis.

2. NS-API plug-in for authentication

Change an HTTP request, before it reaches the customer's web application layer, in order to implement a certain method of authentication.

To prevent a change in the Web Application, it was implemented an alternative authentication method, directed on a NS-API based plug-in of the Sun Microsystems company. Changes were accompanied by a performance test.

3. Empirum Digital Rights Management (DRM)

The product is a big collection of DRM tools. DRM-Internet consists of two parts, first is a virtual drive which ca store data and only allows certain applications to read and write files on the drives. The second part is a software rent shop. Customers are paying not for a classical "eternal" license, but for the time of usage. DRM-LAN is a system designed for corporate usage, it disallows usage of certain Applications (like games), even if they are renamed.

The NT-device driver was developed with Microsoft Visual C++ and DDK (Driver Developer Kit). If a customer buys and downloads an MP3 file, but his/her usage license only allows hearing of the song then the user will not be able to save the file to the classical hard disk, therefore he/she will be unable to re-distribute it. The MP3 file will reside on the special drive, where only the MP3 player application can read. The software rent shop makes an internal change to each EXE file which is offered for renting. This change (code injection) computes the usage times together with a service running on customer side. The network surveillance module is a service that inspects the user processes. When a process is found in the "black-list" it will be immediately terminated.

4. rsync encrypted password file

Another security measure for rsync: encrypted password file.

An external DLL/so, loaded dynamically from rsync, to decrypt the passwords stored in the file. The target was to keep the number of needed changes in the open source rsync project as small as possible; therefore the whole functionality was implemented outside the project, in an extern dynamical loaded library.

8. Dependency checker

A quite big number of software packages have dependencies. The application checks the consistency of each dependency, and then chencks the consistency of the installation requests for each computer in the managed network.

The dependencies are defined in the following format: Tax2005 needs (Adobe Acrobat Reader 6.0 or Adobe Acrobat Reader 5.0) and MDAC and not Tax2004. The program checks if the invalid dependencies are defined, like package P1 needs package P2 and package P2 should not be installed together with P1. It also checks the installation orders, for each computer or organisational unit, if all dependencies are satisfied.

10. Crystal Reports Integration

Application printer capability over Crystal Reports

Crystal Reports was integrated in Empirum Pro, a console management tool developed by matrix42 AG. To demonstrate the integration capability, more reports were developed, regarding hardware inventory, software licensing and installation reports. Also, the customers can build their own reports or can hire matrix42 consultants to write the reports for them. The product functions with MS-SQL and Oracle, using ODBC. The integration was presented at CeBIT 2002.
