Question #: 83
Topic #: 2

[All Professional Cloud Security Engineer Questions]

Your company conducts clinical trials and needs to analyze the results of a recent study that are stored in BigQuery. The interval when the medicine was taken contains start and stop dates The interval data is critical to the analysis, but specific dates may identify a particular batch and introduce bias You need to obfuscate the start and end dates for each row and preserve the interval data.

What should you do?

AUse bucketing to shift values to a predetermined date based on the initial value.

BExtract the date using TimePartConfig from each date field and append a random month and year

CUse date shifting with the context set to the unique ID of the test subject

DUse the FFX mode of format preserving encryption (FPE) and maintain data consistency

Show Suggested Answer

Suggested Answer: A

'Date shifting techniques randomly shift a set of dates but preserve the sequence and duration of a period of time. Shifting dates is usually done in context to an individual or an entity. That is, each individual's dates are shifted by an amount of time that is unique to that individual.'

D is the clear winner here. Format preserving encryption is the way to go - keep the data useful while staying anonymous. Boom, problem solved!

That's true, FPE allows us to obfuscate the dates while preserving the interval data for analysis.

B just sounds like a mess. Randomly appending months and years? No thanks, I'll stick with D and keep my sanity.

I like the idea of bucketing in A, but it might not be precise enough for the clinical trial data. D seems the most robust solution.

C is interesting, but using the test subject ID for date shifting could still reveal sensitive information. I'd prefer a more generic approach.
