Getting To Know ACME Corporation

ACME Corporation is starting out on their data privacy and compliance journey. One of ACME Corporation's goals is to search across the company's network to determine all data storage locations that contain customer information and to ensure these storage locations are adequately protected.

As customer information is always associated with a unique customer ID, ACME Corporation has built a custom GLASS data type to search for customer ID numbers.

What's in a Customer ID?

ACME Corporation's customer ID numbers can fall into two categories: (i) regional, or (ii) worldwide.

The format for customer IDs are as follows:

• Regional: <ccTLD><9-digit serial number><check digit>
  
• Worldwide: WW<YYMMDD><5-digit serial number><check digit>
  

Where:

ACME Corporation expects a customer ID number to only be bounded by non-alphanumeric characters on either side to be valid.

ACME Corporation also identified a set of words (in various supported languages) that can commonly be found within a certain range of a customer ID number. These are known as contextual keywords. For example:

• In English: cust id, custid, customer
• In English and French: client
• In French: cliente
• In German: kunde
• In Korean: 고객

Customer ID GLASS Data Type

Using GLASS Studio, ACME Corporation built two versions of the custom data type to search for customer ID numbers:

• Relaxed version
  • Custom data type name: ACME_CUSTOMER_ID_RELAXED
• Robust version
  • Custom data type name: ACME_CUSTOMER_ID_ROBUST

For a breakdown of how to build these two data types, see Building and Defining GLASS Patterns and GLASS Examples for more information.

Customer ID GLASS Data Type (Relaxed)

As the structure of the customer ID numbers are fairly unique, this version only searches for the customer ID in data storage locations.

MAP 'DAY_OF_MONTH_LOOKUP' 1-31

            (RANGE DIGIT TIMES 2 REQUIRE 'DAY_OF_MONTH_LOOKUP') \

        RANGE DIGIT \
      ) CHECK 'PASSPORTMOD10' \
    ) \
  ) BOUND NONALNUM \
)

Customer ID GLASS Data Type (Robust)

The Robust version of the data type enhances the Relaxed version by searching for customer IDs and specific context (e.g. customer, cliente) surrounding the customer ID numbers for greater pattern matching accuracy.

MAP 'DAY_OF_MONTH_LOOKUP' 1-31
MAP 'MONTH_OF_YEAR_LOOKUP' 1-12
MAP NOCASE 'ACME_CUST_ID_CCTLD' 'AU', 'IE', 'KR', 'SG', 'UK', 'US'
MAP NOCASE 'ACME_CUST_ID_CONTEXTS' 'cust id', 'custid', 'customer', 'client', 'cliente', 'kunde', '고객'
