Memeriksa data sensitif pada gambar

Perlindungan Data Sensitif dapat mendeteksi dan mengklasifikasikan data sensitif dalam gambar. Dengan menggunakan pendeteksi infoType dan pengenalan karakter optik (OCR), Perlindungan Data Sensitif memeriksa teks berenkode base64, mendeteksi data sensitif dalam teks, lalu menampilkan lokasi data sensitif yang terdeteksi.

Catatan: Perlindungan Data Sensitif dapat memeriksa banyak jenis gambar untuk mendeteksi data sensitif, termasuk JPEG, BMP, PNG, dan SVG. Perlindungan Data Sensitif juga dapat memeriksa format file lain seperti PDF, DOCX, XLSX, dan PPTX, tetapi dapat menghasilkan temuan campuran—termasuk offset byte dan kotak pembatas—bergantung pada isi setiap file tertentu. Untuk informasi selengkapnya, lihat Jenis file yang didukung.

Pemeriksaan file menggunakan metode yang dijelaskan dalam topik ini bergantung pada batas ukuran file. Untuk file yang lebih besar, pertimbangkan untuk menggunakan Perlindungan Data Sensitif untuk memindai repositori penyimpanan yang berisi file. Untuk mempelajari lebih lanjut batas ukuran file dan Perlindungan Data Sensitif, lihat Batas penggunaan.

Jika gambar ditetapkan sebagai input, Perlindungan Data Sensitif mendeteksi data sensitif dalam gambar. Output operasi pemeriksaan mencakup infoTypes yang ditemukan, kemungkinan kecocokan, serta nilai koordinat piksel dan panjang yang menunjukkan area tempat Perlindungan Data Sensitif menemukan data sensitif. Koordinat di sudut kiri bawah gambar adalah (0,0).

Memeriksa gambar untuk semua infoType default

Untuk memeriksa data sensitif pada gambar, kirimkan gambar berenkode base64 ke metode content.inspect DLP API. Kecuali Anda menentukan jenis informasi tertentu (infoTypes) yang akan ditelusuri, Perlindungan Data Sensitif akan menelusuri infoType yang paling umum.

Catatan: Untuk mempelajari cara mengenkode gambar menggunakan base64 menggunakan OS atau alat bahasa pemrograman bawaan, lihat encoding Base64 dalam dokumentasi Cloud Vision.

Untuk memeriksa image untuk infoType default:

1. Mengenkode gambar sebagai base64.
2. Kirim permintaan ke metode content.inspect DLP API. Permintaan hanya perlu berisi image berenkode base64 jika Anda ingin memeriksa infoType default.

Misalnya, perhatikan gambar berikut. Gambar ini adalah contoh {i>file<i} gambar standar yang dihasilkan dari pemindaian dokumen kertas.

Gambar asli (klik untuk memperbesar).

Untuk memeriksa infoType default pada gambar ini, kirim permintaan berikut ke metode content.inspect DLP API:

Perlindungan Data Sensitif telah menemukan infoType berikut, meskipun keyakinan kecocokannya untuk setiap info bervariasi:

• Nomor telepon (mungkin tidak)
• Nomor Jaminan Sosial AS (sangat mungkin)
• Alamat email (kemungkinan)
• Nomor telepon (mungkin)
• Tanggal (kemungkinan)

Jika Anda menggambar setiap kotak pembatas pada gambar, bentuknya akan terlihat seperti berikut. Perhatikan bahwa Perlindungan Data Sensitif sering menggunakan beberapa kotak untuk menunjukkan tempat satu instance data sensitif berada dalam gambar.

Kotak pembatas yang ditempatkan di atas gambar (klik untuk memperbesar).

Perhatikan bahwa, selain mendeteksi nomor Jaminan Sosial yang ditulis tangan, alamat email, dan nomor telepon, Perlindungan Data Sensitif juga mendeteksi tahun tersebut. Dengan asumsi bahwa itu bukan perilaku yang optimal, contoh berikutnya menunjukkan cara memeriksa infoType tertentu saja.

Memeriksa gambar untuk infoType tertentu

Jika Anda ingin memeriksa gambar hanya untuk jenis data sensitif tertentu, tentukan infoType bawaan yang sesuai.

Catatan: Anda juga dapat memeriksa data yang cocok dengan deteksi infoType kustom.

Untuk memeriksa infoType tertentu pada gambar:

1. Mengenkode gambar sebagai base64.
2. Kirim permintaan ke metode content.inspect DLP API. Permintaan harus mencakup:
   • Gambar berenkode base64.
   • Satu atau beberapa pendeteksi infoType.

Pertimbangkan gambar asli dari bagian sebelumnya. Untuk memeriksa nomor Jaminan Sosial, alamat email, dan nomor telepon AS saja, kirim JSON berikut ke metode content.inspect DLP API:

Penting: Kode pada halaman ini mengharuskan Anda menyiapkan klien Perlindungan Data Sensitif terlebih dahulu. Untuk mengetahui informasi selengkapnya tentang penginstalan dan pembuatan klien Perlindungan Data Sensitif, lihat Library klien Perlindungan Data Sensitif. (Mengirim JSON ke endpoint REST Perlindungan Data Sensitif tidak memerlukan library klien.)

• macOS: base64 -i input.jpg -o output.txt
• Windows: C:> Base64.exe -e input.jpg > output.txt
• PowerShell: [Convert]::ToBase64String([IO.File]::ReadAllBytes("./input.jpg")) > output.txt
