Handling sensitive data

In certain data-sensitive contexts (for instance, private health records), sharing a report that includes a sample would violate privacy constraints. The following configuration shorthand groups together various options so that only aggregate information is provided in the report and no individual records are shown:

report = df.profile_report(sensitive=True)

Additionally, pandas-profiling does not send data to external services, making it suitable for private data.

Sample and duplicates

Explicitly showing a dataset\'as sample and duplicate rows can be disabled, to guarantee the report does not directly leak any data:

report = df.profile_report(duplicates=None, samples=None)

Alternatively, it is possible to still show a sample but The following snippet demonstrates how to generate the report but using mock/synthetic data in the dataset sample sections. Note that the name and caption keys are optional.

# Replace with the sample you'd like to present in the report (can be from a mock or synthetic data generator)
sample_custom_data = pd.DataFrame()
sample_description = "Disclaimer: the following sample consists of synthetic data following the format of the underlying dataset."

report = df.profile_report(
    sample={
        "name": "Mock data sample",
        "data": sample_custom_data,
        "caption": sample_description,
    }
)

Warning

Be aware when using pandas.read_csv with sensitive data such as phone numbers. pandas' type guessing will by default coerce phone numbers such as 0612345678 to numeric. This leads to information leakage through aggregates (min, max, quantiles). To prevent this from happening, keep the string representation.

pd.read_csv("filename.csv", dtype={"phone": str})

Note that the type detection is hard. That is why visions, a type system to help developers solve these cases, was developed.
