Membuat pendeteksi kamus kustom reguler

Kamus kustom memberikan kemampuan sederhana tetapi efektif untuk mencocokkan daftar kata atau frasa. Anda dapat menggunakan kamus kustom sebagai pendeteksi atau sebagai daftar pengecualian untuk pendeteksi bawaan. Anda juga dapat menggunakan kamus kustom untuk meningkatkan pendeteksi infoType bawaan agar cocok dengan temuan tambahan.

Bagian ini menjelaskan cara membuat pendeteksi kamus kustom reguler dari daftar kata.

Anatomi pendeteksi infoType kustom kamus

Seperti yang diringkas dalam ringkasan API, untuk membuat detektor infoType kustom kamus, Anda menentukan objek CustomInfoType yang berisi hal berikut:

Nama yang ingin Anda berikan ke pendeteksi infoType kustom, dalam objek InfoType.
Nilai Likelihood opsional. Jika Anda menghapus kolom ini, kecocokan dengan item kamus akan menampilkan kemungkinan default VERY_LIKELY.
Objek DetectionRule opsional, atau aturan kata kunci. Aturan ini menyesuaikan kemungkinan temuan dalam jarak tertentu dari kata kunci yang ditentukan. Pelajari lebih lanjut aturan kata panas di Menyesuaikan kemungkinan pencocokan.
Nilai SensitivityScore opsional. Jika Anda menghapus kolom ini, kecocokan dengan item kamus akan menampilkan tingkat sensitivitas default HIGH.

Skor sensitivitas digunakan dalam profil data. Saat membuat profil data Anda, Perlindungan Data Sensitif menggunakan skor sensitivitas infoType untuk menghitung tingkat sensitivitas.
Dictionary, sebagai WordList yang berisi daftar kata yang akan dipindai atau CloudStoragePath ke satu file teks yang berisi daftar kata yang dibatasi baris baru yang akan dipindai.

Sebagai objek JSON, detektor infoType kustom kamus yang menyertakan semua komponen opsional akan terlihat seperti berikut. JSON ini menyertakan jalur ke file teks kamus yang disimpan di Cloud Storage. Untuk melihat daftar kata inline, lihat bagian Contoh, nanti dalam topik ini.

{
  "customInfoTypes":[
    {
      "infoType":{
        "name":"CUSTOM_INFOTYPE_NAME"
      },
      "likelihood":"LIKELIHOOD_LEVEL",
      "detectionRules":[
        {
          "hotwordRule":{
            HOTWORD_RULE
          }
        },
        ...
      ],
      "sensitivityScore":{
          "score": "SENSITIVITY_SCORE"
        },
      "dictionary":
      {
        "cloudStoragePath":
        {
          "path": "gs://PATH_TO_TXT_FILE"
        }
      }
    }
  ],
  ...
}

Detail pencocokan kamus

Berikut adalah panduan tentang cara Sensitive Data Protection mencocokkan kata dan frasa dalam kamus. Poin-poin ini berlaku untuk kamus kustom reguler dan besar:

Kata dalam kamus tidak peka huruf besar/kecil. Jika kamus Anda menyertakan Abby, kamus akan cocok dengan abby, ABBY, Abby, dan sebagainya.
Semua karakter—dalam kamus atau dalam konten yang akan dipindai—selain huruf, angka, dan karakter alfabet lainnya yang terdapat dalam Basic Multilingual Plane Unicode dianggap sebagai spasi kosong saat memindai kecocokan. Jika kamus Anda memindai Abby Abernathy, kamus akan cocok dengan abby abernathy, Abby, Abernathy, Abby (ABERNATHY), dan sebagainya.
Karakter yang mengelilingi kecocokan apa pun harus dari jenis yang berbeda (huruf atau angka) dengan karakter yang berdekatan dalam kata. Jika kamus Anda memindai Abi, kamus akan cocok dengan tiga karakter pertama Abi904, tetapi tidak dengan Abigail.
Kata kamus yang berisi karakter dalam Supplementary Multilingual Plane dari standar Unicode dapat menghasilkan temuan yang tidak terduga. Contoh karakter tersebut adalah emoji, simbol ilmiah, dan skrip historis.

Huruf, angka, dan karakter alfabet lainnya didefinisikan sebagai berikut:

Huruf: karakter dengan kategori umum Lu, Ll, Lt, Lm, atau Lo dalam spesifikasi Unicode
Angka: karakter dengan kategori umum Nd dalam spesifikasi Unicode
Karakter alfabet lainnya: karakter dengan kategori umum Nl dalam spesifikasi Unicode atau dengan properti kontributif Other_Alphabetic seperti yang ditentukan oleh Standar Unicode

Contoh

Daftar kata sederhana

Misalnya, Anda memiliki data yang menyertakan ruangan rumah sakit tempat pasien dirawat selama kunjungan. Lokasi ini mungkin dianggap sensitif dalam set data tertentu, tetapi bukan sesuatu yang akan terdeteksi oleh detektor bawaan Perlindungan Data Sensitif.

Kamar tercantum sebagai:

"RM-Orange"
"RM-Yellow"
"RM-Green"

Perlindungan Data Sensitif telah mengidentifikasi nomor kamar yang ditentukan dalam pesan WordList kamus kustom dengan benar. Perhatikan bahwa item bahkan cocok jika huruf besar/kecil dan tanda hubung (-) tidak ada, seperti pada contoh kedua, "rm green".

Output JSON:

Saat kita mengirim JSON ini ke content:deidentify, JSON akan menampilkan respons JSON berikut:

{
  "item":{
    "value":"jack@example.org accessed customer record of [EMAIL_ADDRESS]"
  },
  "overview":{
    "transformedBytes":"17",
    "transformationSummaries":[
      {
        "infoType":{
          "name":"EMAIL_ADDRESS"
        },
        "transformation":{
          "replaceWithInfoTypeConfig":{

          }
        },
        "results":[
          {
            "count":"1",
            "code":"SUCCESS"
          }
        ],
        "transformedBytes":"17"
      }
    ]
  }
}

Output telah mengidentifikasi user1@example.com dengan benar sebagai cocok dengan pendeteksi infoType EMAIL_ADDRESS dan jack@example.org sebagai cocok dengan pendeteksi infoType kustom DEVELOPER_EMAIL. Perhatikan bahwa karena kita memilih untuk hanya mengubah EMAIL_ADDRESS, jack@example.org dibiarkan apa adanya.

Memperkuat pendeteksi infotype bawaan

Pertimbangkan skenario saat detektor infoType bawaan tidak menampilkan nilai yang benar. Misalnya, Anda ingin menampilkan kecocokan pada nama orang, tetapi detector PERSON_NAME bawaan Sensitive Data Protection gagal menampilkan kecocokan pada beberapa nama orang yang umum di set data Anda.

Dengan Sensitive Data Protection, Anda dapat meningkatkan kemampuan detektor infoType bawaan dengan menyertakan detektor bawaan dalam deklarasi untuk detektor infoType kustom, seperti yang ditunjukkan dalam contoh berikut. Cuplikan ini mengilustrasikan cara mengonfigurasi Perlindungan Data Sensitif sehingga pendeteksi infoType bawaan PERSON_NAME juga akan cocok dengan nama "Quasimodo:"
