צנזור מידע אישי רגיש מטקסט

‫Sensitive Data Protection יכול לצנזר או להסתיר מידע אישי רגיש ממחרוזת טקסט. אפשר להזין מידע טקסטואלי ל-API באמצעות JSON over HTTP, או להשתמש באחת מספריות הלקוח כדי לעשות זאת באמצעות כמה שפות תכנות פופולריות.

ה-API‏ projects.content.deidentify מקבל את הארגומנטים הבאים:

מחרוזת טקסט.
טקסט של placeholder שיחליף כל מידע אישי רגיש שזוהה. בדוגמה הזו, הנתונים מוחלפים ב-infoType התואם שלהם.
רשימה של infoTypes אחד או יותר שרוצים לצנזר.

הפונקציה Sensitive Data Protection מחזירה את המחרוזת עם מידע אישי רגיש שמוחלף על ידי ה-פלייסהולדר שבחרתם.
