Create a Fingerprint

You can create and use fingerprints for structured data or unstructured data. Structured, or Exact Data Matching (EDM) fingerprints, allow you to monitor your organizations in a row and column format typically extracted from a database in CSV format. Unstructured or Index Document Matching (IDM) fingerprints work by content matching indexed documents and images. Once your data is fingerprinted, you can add a DLP Policy rule to leverage that indexed data. 

Create a Structured Data Fingerprint

  1. Choose Policy > DLP Policies > Fingerprints. 
  2. Click Create New Fingerprint > Structured Data Fingerprint.
  3. Fingerprint Name. Enter a name for the Fingerprint. 
  4. Source File. Enter the path to the source file that holds the data you want to fingerprint. For example:
  5. Folder Path to Locally Generated Hashed Files. Enter the path to the folder where your locally generated hashed files are stored. Space allocated for this should be about 10–20% of the size of data to be fingerprinted. For example:
  6. Column Separator. Select the delimiter that separates the columns of your source file: either Comma, Tab, or Pipe.  
  7. First row of file contains column names. Activate this checkbox if the first row of your source file contains column names. 
  8. Column. If the field names aren't automatically detected, enter the first Field Name for your source file. Then select the Field Type from the menu. Selections include:
    • Alphabetic. Alphabetic characters. 
    • Number. Numbers supported with decimals.
    • Alphanumeric. Alphanumeric characters. 
    • Zip Code. ##### or #####-####
    • Email. LOCAL_SUBPART ('.' LOCAL_SUBPART)* '@' DOMAIN_SUBPART ('.' DOMAIN_SUBPART)*;
    • Date. ##/##/#### or ##-##-####
    • Phone. (###)###-#### or ###-###-####
    • Credit Card Number. CCNs formatted with decimals, spaces, or underscores, separated by pipes or semicolons. 
    • Social Security Number. ###-##-####, or ### ## ####, or ###.##.###, separated by pipes or semicolons. 
    • Identifier. Letters and numbers with hyphens and decimals. 
    • Generic. Used for exact cell match. 
    • Do Not Index. Select this Field Type to mark the column as Do Not Index. (This option is available with DLP Integrator 4.1 and later.)
  9. Click + to add as many Columns as required. 
  10. Click Save. 

The new Structured Data Fingerprint is created and appears on the Fingerprint page. Next, generate an index.

Create an Unstructured Data Fingerprint

  1. Choose Policy > DLP Policies > Fingerprints. 
  2. Click Create New Fingerprint > Unstructured Data Fingerprint. 
  3. Fingerprint Name. Enter a name for the Fingerprint. 
  4. Machine Path. Enter the path to the computer that holds the files you want to fingerprint. Click + to add more paths, if necessary. For example:
  5. Folder Path to Locally Generated Hashed Files. Enter the path to the folder where your locally generated hashed files are stored. Space allocated for this should be about 10–20% of the size of input paths/folders. For example:
  6. File Type Exclusions. Enter any file types to be excluded. (Archive files such as ZIP files are automatically excluded.)
  7. Click Save. 

The new Unstructured Data Fingerprint is created and appears on the Fingerprint page. Next, generate an index.
