Cloud Data Loss Prevention (Cloud DLP) ist jetzt Teil des Schutzes sensibler Daten. Der API-Name bleibt unverändert: Cloud Data Loss Prevention API (DLP API). Informationen zu den Diensten, die den Datenschutz enthalten, finden Sie
in dieser Übersicht.

"""Uses the Data Loss Prevention API to analyze a file for protected data.
Args:
project: The Google Cloud project id to use as a parent resource.
filename: The path to the file to inspect.
info_types: A list of strings representing info types to look for.
A full list of info type categories can be fetched from the API.
min_likelihood: A string representing the minimum likelihood threshold
that constitutes a match. One of: 'LIKELIHOOD_UNSPECIFIED',
'VERY_UNLIKELY', 'UNLIKELY', 'POSSIBLE', 'LIKELY', 'VERY_LIKELY'.
max_findings: The maximum number of findings to report; 0 = no maximum.
include_quote: Boolean for whether to display a quote of the detected
information in the results.
mime_type: The MIME type of the file. If not specified, the type is
inferred via the Python standard library's mimetypes module.
Returns:
None; the response from the API is printed to the terminal.
