Your company outsourced the development of the customer relationship management system. The software development vendor requests customer profiles for stress testing. To simulate the real stress and performance, which of the following is the best testing data?
A. Large amount of actual customer data
B. Small amount of anonymized customer data
C. Large amount of pseudo-anonymized customer data
D. Small amount of tokenized customer data
Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.
My suggested answer is C. Large amount of pseudo-anonymized customer data.
Stress testing needs a large amount of data to gradually increase the system load to observe system performance over time.
Personal data or PII shall not be used as test data in testing. Personal data can be used for testing only if it is anonymized or pseudo-anonymized.
Article 4 (1) ‘personal data’ means any information relating to an identified or identifiable natural person (‘data subject’); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person;
Article 4 (5) ‘pseudonymisation’ means the processing of personal data in such a manner that the personal data can no longer be attributed to a specific data subject without the use of additional information, provided that such additional information is kept separately and is subject to technical and organisational measures to ensure that the personal data are not attributed to an identified or identifiable natural person.
Pseudonymization is also known as tokenization, and can be configured to provide token data that matches the field type and expected data value, allowing even legacy databases to maintain structure.
