Example - Creating Token Data Elements

This example shows how to create numeric tokenization data element that is used to tokenize numerical data.

To create a structured data element:

1. On the ESA Web UI, navigate to Policy Management > Data Elements & Masks > Data Elements.

2. Click Add New Data Element.

   The New Data Element screen appears.

3. Select Structured from Type.

4. Type a unique name for the data element in the Name textbox.

   The maximum length of the data element name is 55 characters.

5. Type the description for the data element in the Description textbox.

6. Select the protection method from the Method drop-down. In this example, select Tokenization.

7. Select the tokenization data type from the Data Type drop down. In this example, select Numeric (0-9).

   For more information about the different data types, refer to the Protection Methods Reference Guide.

8. Select the tokenizer from the Tokenizer drop-down.

   For more information about the different token elements, refer to the Protection Methods Reference Guide.

9. If the Tokenizer should leave characters in clear, then set the number of characters from left and from right in the From Left and From Right text boxes.

   For more information on the maximum and minimum input values for these fields, refer to the section Minimum and Maximum Input Length in the Protection Methods Reference Guide.

10. If the token length needs to be equal to the provided input, then select the Preserve length check box.

11. If you select the Preserve length option, then you can also choose the behavior for short data tokenization in the Allow Short Data drop-down.

    If you require short data tokenization with existing data that was previously not protected using short data enabled data element, then you must do the following:

    1. Unprotect the existing data with the old data element.
    2. Create a new data element that is enabled with short data.
    3. Reprotect the unprotected data with the new short data enabled data element. For more information about length preservation and short data tokenization, refer to section Length Preserving and Short Data Tokenization in Protection Methods Reference Guide.

12. Click Save.

A message Data Element has been saved successfully appears.
