Menyamarkan data sensitif dari gambar

Sensitive Data Protection dapat menyamarkan teks sensitif dari gambar. Dengan menggunakan detektor infoType dan Cloud Vision, Sensitive Data Protection memeriksa teks dalam gambar, mendeteksi data sensitif dalam teks, lalu menampilkan gambar dengan data sensitif yang cocok yang disamarkan oleh persegi panjang buram.

Misalnya, perhatikan gambar "sebelum" dan "setelah" berikut. Gambar asli adalah contoh file gambar standar yang dihasilkan dari pemindaian dokumen kertas. Dalam contoh ini, Perlindungan Data Sensitif telah dikonfigurasi untuk menyamarkan nomor Jaminan Sosial, alamat email, dan nomor telepon Amerika Serikat menggunakan persegi panjang dengan warna berbeda, bergantung pada konten.

Gambar sebelum dan sesudah disamarkan (klik untuk memperbesar).

1. Gambar yang dipindai sebelum penyamaran gambar
2. Gambar yang dipindai setelah penyamaran gambar

Batasan dan pertimbangan

Pertimbangkan poin-poin berikut saat menyamarkan konten dari gambar.

Jenis file yang didukung

Sensitive Data Protection dapat menyamarkan data sensitif dari banyak jenis gambar, termasuk JPEG, BMP, dan PNG. Untuk mengetahui informasi selengkapnya, lihat Jenis file yang didukung.

Penyamaran konten tidak didukung untuk file SVG, PDF, XLSX, PPTX, atau DOCX.

Menemukan batas

Saat menyamarkan data dari gambar, batas penemuan tidak berlaku. Hal ini dapat menyebabkan hasil yang tidak terduga atau berpotensi tidak konsisten, dengan hanya beberapa data yang disamarkan. Jika Anda menyertakan FindingLimits dalam permintaan, Perlindungan Data Sensitif akan menghasilkan error.

Sebelum memulai

1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

2. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   Go to project selector

3. Make sure that billing is enabled for your Google Cloud project.

4. Enable the DLP API.

Menyamarkan semua infoType default dari gambar

Untuk menyamarkan data sensitif dari gambar, kirimkan gambar ke metode image.redact DLP API. Kecuali jika Anda menentukan jenis informasi tertentu (infoTypes) untuk ditelusuri, Sensitive Data Protection akan menelusuri infoType yang paling umum.

Untuk menyamarkan infoTypes default dari gambar, lakukan hal berikut:

1. Enkode gambar sebagai string base64.

   Jika Anda berencana menggunakan salah satu library klien Sensitive Data Protection untuk melakukan tugas ini, lewati langkah ini.

2. Kirim permintaan ke metode image.redact.

   Jika Anda ingin menyamarkan infoTypes default, permintaan hanya memerlukan gambar yang dienkode base64.

Misalnya, perhatikan gambar berikut. Ini adalah contoh file gambar standar yang dihasilkan dari pemindaian dokumen kertas.

Gambar asli yang tidak disamarkan (klik untuk memperbesar).

Untuk menyamarkan infoTypes default dari gambar ini, kirim permintaan berikut ke metode image.redact DLP API:

REST

Penting: Sebelum mengirim permintaan ini ke REST API, gunakan utilitas base64 untuk mengenkode gambar menjadi data teks ASCII, lalu ganti placeholder [BASE64-ENCODED-IMAGE] dengan teks yang dienkode base64. Sebagian besar lingkungan pengembangan berisi utilitas base64 native. Untuk mengenkode file gambar:

• Linux: base64 input.jpg > output.txt
• 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

{
  "byteItem": {
    "data": "[BASE64-ENCODED-IMAGE]",
    "type": "IMAGE_JPEG"
  }
}

Sensitive Data Protection menampilkan hal berikut:

    {
      "redactedImage": "[BASE64-ENCODED-IMAGE]"
    }

Mendekode gambar yang dienkode base64.

Gambar yang dihasilkan akan terlihat seperti berikut:

Gambar yang disamarkan, semua infoTypes (klik untuk memperbesar).

Perhatikan bahwa selain menyamarkan nomor Jaminan Sosial yang ditulis tangan, alamat email, dan nomor telepon, Perlindungan Data Sensitif juga menyamarkan tahun. Bagian berikutnya menunjukkan cara menyamarkan infoTypes tertentu saja.

Tips: Bersama dengan gambar yang dihasilkan, Anda dapat mendapatkan laporan nilai panjang dan koordinat piksel yang menunjukkan area tempat kotak penyamaran digambar. Ini adalah informasi yang sama dengan yang ditampilkan pemeriksaan gambar. Untuk mengaktifkan fungsi ini, tetapkan includeFindings ke true dalam permintaan Anda ke image.redact.

Menyamarkan infoType tertentu dari gambar

Jika Anda hanya ingin menyamarkan data sensitif tertentu dari gambar, tentukan infoTypes bawaan yang sesuai.

Catatan: Anda juga dapat menyamarkan data yang cocok dengan detektor infoType kustom.

Untuk menyamarkan infoTypes tertentu dari gambar, kirim permintaan ke metode image.redact DLP API. Permintaan harus menyertakan hal berikut:

• Gambar.
• Satu atau beberapa pendeteksi infoType.

Pertimbangkan gambar asli dari bagian sebelumnya. Untuk menyamarkan hanya nomor Jaminan Sosial, alamat email, dan nomor telepon Amerika Serikat, kirimkan JSON berikut ke metode image.redact DLP API:

REST

Penting: Sebelum mengirim permintaan ini, gunakan utilitas base64 untuk mengenkode gambar menjadi data teks ASCII, lalu ganti placeholder [BASE64-ENCODED-IMAGE] dengan teks yang dienkode base64. Sebagian besar lingkungan pengembangan berisi utilitas base64 native. Untuk mengenkode file gambar:

• Linux: base64 input.jpg > output.txt
• 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

    {
      "byteItem": {
        "data": "[BASE64-ENCODED-IMAGE]",
        "type": "IMAGE_JPEG"
      },
      "imageRedactionConfigs": [
        {
          "infoType": {

      ]
    }

Sensitive Data Protection menampilkan hal berikut:

    {
      "redactedImage": "[BASE64-ENCODED-IMAGE]"
    }

Mendekode gambar yang dienkode base64.

Gambar yang dihasilkan akan terlihat seperti berikut:

Gambar yang disamarkan, tiga infoTypes (klik untuk memperbesar).

Anda dapat memberi kode warna pada informasi yang disamarkan berdasarkan infoType jika ingin mengetahui secara sekilas informasi yang telah disamarkan. Lihat bagian berikut untuk mengetahui informasi selengkapnya.

Menyamarkan infoType dari gambar dengan kode warna

Untuk memberi kode warna pada informasi yang disamarkan menurut infoType, Anda akan menyambungkan detektor infoType dengan nilai ruang warna RGB.

Untuk memberi kode warna infoTypes yang disamarkan dari gambar, kirim permintaan ke metode image.redact DLP API. Permintaan harus menyertakan hal berikut:

• Gambar.
• Satu atau beberapa detektor infoType, yang masing-masing diberi warna menggunakan nilai ruang warna RGB.

Catatan: Nilai ruang warna dinyatakan dalam tiga kromatikitas merah, hijau, dan biru. Setiap nilai antara 0 dan 1, inklusif. Jika Anda terbiasa mengekspresikan nilai kromatikitas RGB antara 0 dan 255, inklusif, Anda harus membagi setiap nilai dengan 255 sebelum menyertakannya dalam panggilan ke image.redact. Misalnya, nilai RGB ungu (77,26,153) akan menjadi sekitar (0,3,0,1,0,6).

Pertimbangkan gambar asli dari bagian pertama. Untuk menyamarkan nomor Jaminan Sosial Amerika Serikat dengan kotak ungu, alamat email dengan kotak hijau, dan nomor telepon dengan kotak oranye, kirim JSON berikut ke metode image.redact DLP API:

Penting: Kode di halaman ini mengharuskan Anda menyiapkan klien Perlindungan Data Sensitif terlebih dahulu.

Penting: Sebelum mengirim permintaan ini, gunakan utilitas base64 untuk mengenkode gambar menjadi data teks ASCII, lalu ganti placeholder [BASE64-ENCODED-IMAGE] dengan teks yang dienkode base64. Sebagian besar lingkungan pengembangan berisi utilitas base64 native. Untuk mengenkode file gambar:

• Linux: base64 input.jpg > output.txt
• 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

Mendekode gambar yang dienkode base64.

Gambar yang dihasilkan akan terlihat seperti berikut:

Gambar yang disamarkan, tiga infoTypes diberi kode warna (klik untuk memperbesar).

Menyamarkan semua teks dari gambar

Perlindungan Data Sensitif juga berisi opsi untuk menyamarkan semua teks yang terdeteksi dalam gambar.

Untuk menyamarkan semua teks dari gambar, kirim permintaan ke metode image.redact DLP API. Permintaan harus menyertakan hal berikut:

• Gambar.
• Opsi redactAllText ditetapkan ke true.

Catatan: Jika Anda menyertakan infoType dalam objek imageRedactionConfigs, Sensitive Data Protection akan mengabaikannya.

Pertimbangkan gambar asli dari bagian pertama. Untuk menyamarkan semua teks, kirim JSON berikut ke metode image.redact DLP API:

REST

Penting: Sebelum mengirim permintaan ini, gunakan utilitas base64 untuk mengenkode gambar menjadi data teks ASCII, lalu ganti placeholder [BASE64-ENCODED-IMAGE] dengan teks yang dienkode base64. Sebagian besar lingkungan pengembangan berisi utilitas base64 native. Untuk mengenkode file gambar:

• Linux: base64 input.jpg > output.txt
• 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

    {
      "byteItem": {
        "data": "[BASE64-ENCODED-IMAGE]",
        "type": "IMAGE_JPEG"
      },
      "imageRedactionConfigs": [
        {
          "redactAllText": true
        }
      ]
    }

Sensitive Data Protection menampilkan hal berikut:

    {
      "redactedImage": "[BASE64-ENCODED-IMAGE]"
    }

Mendekode gambar yang dienkode base64.

API menampilkan gambar yang sama dengan yang Anda berikan, tetapi teks apa pun yang diidentifikasi sebagai berisi informasi sensitif menurut kriteria Anda telah disamarkan.

Gambar yang dihasilkan akan terlihat seperti berikut:

Gambar yang disamarkan, semua teks (klik untuk memperbesar).
