Quick Start Guide

PeriCAT is an Java application which runs on Linux, OS X and Windows systems. The only requirement is a Java 7 installation. Execute the .jar file with your operating system specific method (Windows: double-click, Linux/OS X: java -jar PeriCAT.jar).

It follows a short PeriCAT step by step guide.

1.Start the tool. You will see three main tabs. Open the information encapsulation tab.

2.Decide which are the carrier and which are the payload files; In most cases the carrier consists of the “DO” files, and the payload encompasses all metadata. Add the files to the tool.

3.Switch to the scenario tab: (Using the scenario tab is optional and can be skipped, if you know which algorithm do you want to use)

a. Create a new profile. Enter a profile name and add a meaningful description.

b. Complete the user scenario questionnaire. Exclude criteria which are not relevant for your scenario. Read the tooltips for a further description of a criterion. Adjust the sliders to weight the criteria. Observe high score changes while you adjust the sliders.

c. Save your scenario. Investigate the high score, especially the IE techniques with the lowest distance to your scenario. Choose one of the suggested techniques, and click the “use this technique” button. The tool will switch back to the encapsulation tab.

4.Your chosen IE technique is preselected. If it is displayed in red, it can’t be used for the dataset. Consider to choose another algorithm.

5.If the IE technique has configuration options, a configuration interface will be shown. Configure the algorithm, if necessary.

6.Be sure that the encapsulation option “Use selected algorithm” is selected.

7.Press the encapsulate button. The results will be shown in an output panel at the bottom of the encapsulation tab.

8.For decapsulation switch to the decapsulation tab. Your encapsulated information are shown here as option to be decapsulated. If the tool was closed, you have to add the file manually with the add button. Select them.

9.Select the algorithm, which you used for encapsulation. This will save a lot of time, which the tool would need to guess the used algorithm.

10.Press the decapsulation button. The original files should be shown at the output panel of the Decapsulation tab.

11.Select one of the output files, to get some further information.

12.Close the tool. This is the end of the tutorial.
