Ispezione delle immagini per l'individuazione di dati sensibili

Sensitive Data Protection può rilevare e classificare i dati sensibili all'interno di un'immagine. Utilizzando i rivelatori di infoType e il riconoscimento ottico dei caratteri (OCR), la funzionalità di protezione dei dati sensibili ispeziona un'immagine codificata in base64 per rilevare il testo, rileva i dati sensibili all'interno del testo e restituisce le posizioni di eventuali dati sensibili rilevati.

Data un'immagine come input, Sensitive Data Protection rileva i dati sensibili nell'immagine. L'output di un'operazione di ispezione include gli infoTypes trovati, la probabilità della corrispondenza e i valori di lunghezza e coordinata dei pixel che indicano le aree in cui la Protezione dei dati sensibili ha trovato i dati sensibili. Le coordinate nell'angolo inferiore sinistro di un'immagine sono (0,0).

Ispezione di un'immagine per tutti gli infoType predefiniti

Per ispezionare un'immagine alla ricerca di dati sensibili, invia un'immagine con codifica base64 al metodo content.inspect dell'API DLP. A meno che non specifichi tipi di informazioni specifici (infoTypes) da cercare, Sensitive Data Protection cercherà gli infoType più comuni.

Per ispezionare un'immagine alla ricerca di infoType predefiniti:

  1. Codifica l'immagine in base64.
  2. Invia una richiesta al metodo content.inspect dell'API DLP. La richiesta deve contenere solo l'immagine con codifica base64 se vuoi controllare gli infoType predefiniti.

Ad esempio, considera l'immagine seguente. Questa immagine è un esempio di un tipico file immagine generato dalla scansione di un documento cartaceo.

Sensitive Data Protection ha trovato i seguenti infoType, anche se la confidenza della corrispondenza per ciascuno varia:

  • Un numero di telefono (improbabile)
  • Un numero di previdenza sociale statunitense (molto probabile)
  • Un indirizzo email (probabile)
  • Un numero di telefono (possibile)
  • Una data (probabile)

Se disegnassi ciascuno dei riquadri di delimitazione sull'immagine, il risultato sarebbe simile al seguente. Tieni presente che la protezione dei dati sensibili utilizza spesso più caselle per indicare dove si trova una singola istanza di dati sensibili nell'immagine.

Riquadri di delimitazione sovrapposti all'immagine.
Riquadri di delimitazione sovrapposti all'immagine (fai clic per ingrandire).

Tieni presente che, oltre a rilevare il codice fiscale, l'indirizzo email e il numero di telefono scritti a mano, la funzionalità Protezione dei dati sensibili ha rilevato anche l'anno. Supponendo che questo non sia un comportamento ottimale, l'esempio seguente mostra come eseguire l'ispezione solo per determinati infoType.

Ispezione di un'immagine per l'individuazione di infoType specifici

Se vuoi ispezionare un'immagine solo per determinati tipi di dati sensibili, specifica gli infoType integrati corrispondenti.

Per ispezionare un'immagine alla ricerca di infoType specifici:

  1. Codifica l'immagine in base64.
  2. Invia una richiesta al metodo content.inspect dell'API DLP. La richiesta deve includere:

Considera l'immagine originale della sezione precedente. Per eseguire l'ispezione solo per codice fiscali, indirizzi email e numeri di telefono degli Stati Uniti, invia il seguente JSON al metodo content.inspect dell'API DLP:
