Cloud Data Loss Prevention (Cloud DLP) is now a part of Sensitive Data Protection. The API name remains the same: Cloud Data Loss Prevention API (DLP API). For information about the services that make up Sensitive Data Protection, see Sensitive Data Protection overview.

דוגמאות להסרת פרטי זיהוי מנתונים בטבלה

בעזרת Sensitive Data Protection אפשר לזהות, לסווג ולהסיר פרטי זיהוי של מידע אישי רגיש בנתונים מובְנים. כשמסירים את פרטי הזיהוי מתוכן בטבלה, המבנה והעמודות מספקים ל-Sensitive Data Protection רמזים נוספים שיכולים לעזור לו לספק תוצאות טובות יותר בתרחישי שימוש מסוימים. לדוגמה, אתם יכולים לסרוק עמודה אחת כדי לחפש סוג נתונים מסוים במקום את כל מבנה הטבלה.

במאמר הזה מוסבר איך להגדיר הסרת פרטי זיהוי של מידע אישי רגיש בטקסט מובנה. הסרת פרטי הזיהוי מופעלת באמצעות טרנספורמציות של רשומות. הטרנספורמציות האלה מוחלות על ערכים בנתוני טקסט בטבלה שמזוהים כ-infoType ספציפי, או על עמודה שלמה של נתונים בטבלה.

בנושא הזה מופיעות גם דוגמאות לטרנספורמציות של נתונים בטבלה באמצעות שיטת הגיבוב הקריפטוגרפי. שיטות הטרנספורמציה הקריפטוגרפיות הן ייחודיות כי הן דורשות מפתח קריפטוגרפי.

אפשר להוסיף את ה-JSON שמופיע בדוגמאות הבאות לכל בקשה של הסרת פרטי הזיהוי במאפיין "deidentifyConfig" (DeidentifyConfig). כדי לנסות את קובץ ה-JSON לדוגמה ב-APIs Explorer, לוחצים על הקישור "APIs Explorer example".

שינוי עמודה בלי בדיקה

כדי לשנות עמודה ספציפית שהתוכן שלה כבר ידוע, אפשר לדלג על הבדיקה ולציין את השינוי ישירות. בדוגמה שאחרי הטבלה, העמודה HAPPINESS SCORE מחולקת לקטגוריות במרווחים של 10.

    """Uses the Data Loss Prevention API to de-identify sensitive data in a
    table by replacing them with fixed size bucket ranges.
    Args:
        project: The Google Cloud project id to use as a parent resource.
        table_data: Dictionary representing table data.
        deid_content_list: A list of fields in table to de-identify.
        bucket_size: Size of each bucket for fixed sized bucketing
            (except for minimum and maximum buckets). So if ``bucketing_lower_bound`` = 10,
            ``bucketing_upper_bound`` = 89, and ``bucket_size`` = 10, then the
            following buckets would be used: -10, 10-20, 20-30, 30-40,
            40-50, 50-60, 60-70, 70-80, 80-89, 89+.
       bucketing_lower_bound: Lower bound value of buckets.
       bucketing_upper_bound:  Upper bound value of buckets.

    Returns:
       De-identified table is returned;
       the response from the API is also printed to the terminal.

שינוי ממצאים באמצעות טרנספורמציה של גיבוב קריפטוגרפי

בדוגמאות הבאות ב-JSON, נעשה שימוש בטרנספורמציות של infoType כדי להורות ל-DLP API לבדוק את כל מבנה הטבלה ולאתר infoTypes ספציפיים, ואז להצפין את הערכים התואמים באמצעות CryptoKey זמני.

בדוגמה הבאה מוצגת הסרת פרטי הזיהוי של שני סוגי מידע באמצעות טרנספורמציה של גיבוב קריפטוגרפי.

שינוי הממצאים באמצעות שתי טרנספורמציות נפרדות של גיבוב קריפטוגרפי

בדוגמה הזו מוסבר איך להשתמש במפתחות קריפטוגרפיים שונים בטרנספורמציות שונות, במסגרת הגדרה אחת של הסרת פרטי הזיהוי. קודם כל, מצהירים על טרנספורמציה של השדה userid. הטרנספורמציה הזו לא כוללת טרנספורמציות של infoType, ולכן השדה "userid" בכל שורה עובר טרנספורמציה, בלי קשר לסוג הנתונים שלו. אחר כך, מצהירים על טרנספורמציה נוספת של שדה, הפעם בשדה comments.

קלט:

userid	תגובות
user1@example.org	כתובת האימייל שלי היא user1@example.org ומספר הטלפון שלי הוא 858-555-0222
abbyabernathy1	מזהה המשתמש שלי הוא abbyabernathy1 וכתובת האימייל שלי היא aabernathy@example.com
