Encrypt Your Stream in IBM SPSS Modeler

To improve your experience using IBM SPSS Modeler, the Version 1 SPSS experts have created various Tech Tips. This Tech Tip shows how to encrypt your stream in IBM SPSS Modeler. 

IBM SPSS Modeler is an extensive predictive analytics platform designed to bring predictive intelligence to decisions made by individuals, groups, systems, and the enterprise. Modeler has an easy-to-use drag-and-drop user interface with a complete set of tools for accessing data, data examination, preparation, modelling, evaluation, and deployment.  

IBM SPSS Modeler users have a complete toolset to build predictive models from start to finish. Modeler uses node-based, visual programming. Users pick nodes from palettes and place them on the stream canvas. Once nodes have been placed on the stream canvas and edited, they can be linked to form a stream. A stream represents a flow of data through several operations (nodes) to a destination that can be in the form of output (either text or chart), a model, or the export of data to another format (e.g., a database).  

The stream is the complete set of steps to build a predictive model. Encrypt your stream in Modeler to protect data, data examination, preparation, modelling steps, and information. Encryption also ensures that only approved users can access the stream. Go to the File menu and select Save Stream As to encrypt a stream. This will open the Save Stream As window. At the bottom of the window is the option to use Encryption. Click on the Options button. The Encryption Options window will open. Tick Encrypt this file and enter a password. Ensure that you read the Warning message. Click OK. Then save the stream. When you reopen the stream, you will need to enter a password. Once you enter a password, the stream will open.
