Document Intelligence Identity document (ID) model combines Optical Character Recognition (OCR) with deep learning models to analyze and extract key information from identity documents. The API analyzes identity documents (including the following) and returns a structured JSON data representation.

Region Document types
Worldwide Passport Book, Passport Card
United States Driver License, Identification Card, Residency Permit (Green card), Social Security Card, Military ID
Europe Driver License, Identification Card, Residency Permit
India Driver License, PAN Card, Aadhaar Card
Canada Driver License, Identification Card, Residency Permit (Maple Card)
Australia Driver License, Photo Card, Key-pass ID (including digital version)

Document Intelligence can analyze and extract information from government-issued identification documents (IDs) using its prebuilt IDs model. It combines our powerful Optical Character Recognition (OCR) capabilities with ID recognition capabilities to extract key information from Worldwide Passports and U.S. Driver's Licenses (all 50 states and D.C.). The IDs API extracts key information from these identity documents, such as first name, surname, date of birth, document number, and more. This API is available in the Document Intelligence v2.1 as a cloud service.

Identity document processing

Identity document processing involves extracting data from identity documents either manually or by using OCR-based technology. ID document processing is an important step in any business operation that requires proof of identity. Examples include customer verification in banks and other financial institutions, mortgage applications, medical visits, claim processing, hospitality industry, and more. Individuals provide some proof of their identity via driver licenses, passports, and other similar documents so that the business can efficiently verify them before providing services and benefits.

Data extraction

The prebuilt IDs service extracts the key values from worldwide passports and U.S. Driver's Licenses and returns them in an organized structured JSON response.

ID document model data extraction

Extract data, including name, birth date, and expiration date, from ID documents. You need the following resources:

  • An Azure subscription—you can create one for free.

  • A Document Intelligence instance in the Azure portal. You can use the free pricing tier (F0) to try the service. After your resource deploys, select Go to resource to get your key and endpoint.

Note

Document Intelligence Studio is available with v3.1 and v3.0 APIs and later versions.

  1. On the Document Intelligence Studio home page, select Identity documents.

  2. You can analyze the sample invoice or upload your own files.

  3. Select the Run analysis button and, if necessary, configure the Analyze options:

  6. In the Document Intelligence service endpoint field, paste the endpoint that you obtained with your Document Intelligence subscription.

  7. In the key field, paste the key you obtained from your Document Intelligence resource.

    Screenshot of select document type dropdown menu.

  8. Select Run analysis. The Document Intelligence Sample Labeling tool calls the Analyze Prebuilt API and analyzes the document.

  9. View the results - see the key-value pairs extracted, line items, highlighted text extracted, and tables detected.

  10. Download the JSON output file to view the detailed results.

    • The "readResults" node contains every line of text with its respective bounding box placement on the page.
    • The "selectionMarks" node shows every selection mark (checkbox, radio mark) and whether its status is selected or unselected.
    • The "pageResults" section includes the tables extracted. For each table, Document Intelligence extracts the text, row, and column index, row and column spanning, bounding box, and more.
    • The "documentResults" field contains key/value pairs information and line items information for the most relevant parts of the document.

Note

The Sample Labeling tool does not support the BMP file format. This is a limitation of the tool not the Document Intelligence Service.
