Zero-Trust Web ID Scanning for Chilean Identity Documents: Secure KYC with No Data Exposure

Chile’s business services are moving steadily into digital channels. As a result, more customer onboarding and KYC processes now begin in a browser. In this environment, personal data security is increasingly becoming a central design requirement, alongside speed and ease of KYC.

Recent global incidents show what can happen when large collections of identity documents are held in remote systems. In September 2026, IDScan.net acknowledged unauthorized access to data stored in customer accounts in its cloud, and 170 million scanned identity documents were offered for sale. This case demonstrates the risk created when document images are transferred to and retained by external parties. In this blog post, we explain how OCR Studio’s Zero-Trust web ID scanner captures and extracts data from Chilean ID cards, passports, and driver’s licenses directly in the browser, without sending ID images and data to third parties.

How Zero-Trust ID Scanning Reduces Exposure in Onboarding and KYC

Zero-Trust ID scanning starts with a simple rule: no external party should be trusted to receive a customer’s identity document. In a cloud workflow, a browser sends the image to a remote provider, which scans it and returns the extracted fields. This adds a third party and an avoidable transfer of highly sensitive information.

OCR Studio’s ID card and passport scanner performs ID OCR in the browser, so the capture, scanning, and data extraction take place 100% locally:

• The full document image and extracted fields are not sent to an external OCR provider;
• No third party needs custody of the document to complete the scan;
• The business has fewer vendors and data transfers to map, govern, and monitor.

What’s more important, an incident at an external OCR provider cannot expose documents that were never transferred to it.

This architecture supports a clearer approach to Chilean data protection law. Chilean Law No. 19628 remains the applicable personal data statute, and Article 11 requires those responsible for stored personal data to protect it with due care. Law No. 21719 adds explicit duties covering purpose limitation, proportionality, security, and data protection by design and by default. Keeping the ID OCR stage on the user’s device reduces unnecessary transfers and copies, while making vendor oversight, retention rules, and data-flow documentation simpler.

Why Client-Side Web ID OCR Is Faster and Safer Than Cloud APIs

A cloud OCR API depends on remote handling. The browser uploads an image, the provider receives and scans it, and the result goes back over the network. Every ID scan relies on a data transfer and an external endpoint. The upload and response also add delay, especially on mobile connections or with high-resolution images.

OCR Studio’s client-side Web ID OCR runs inside the webpage that is already opened. The customer uses a phone camera or uploads an image, and the browser produces structured fields locally. For the ID scanning stage, this provides zero data exposure to an external scanning service. Here’s how OCR Studio’s web ID scanner outperforms cloud OCR APIs:

Area	Cloud OCR API	OCR Studio’s client-side Web ID scanner
Document route	The browser uploads the document to remote infrastructure	The document stays on the user’s device within a single browser session
External access	A third-party provider receives the image and extracted fields	No external party receives the image or extracted data
Response time	Upload, remote computation, and the return response add network delay	The ID scanning workflow is near-instant as local computation removes the upload and return round trip
Onboarding experience	Can be slow and inconvenient as the scan depends on external services, which adds delay	Smooth user experience as the customer stays on the business’s webpage and installs no additional plugin

For a business, local data extraction reduces manual entry and the errors that come with typing names, dates, document numbers, or RUN/RUT values. The structured result can populate the company’s KYC form immediately, subject to the company’s own rules for which fields it needs and submits. Near-instant ID capture and no corrections reduce the time and effort required for onboarding, which can help more customers complete the process instead of abandoning it. Businesses can assess this experience in the OCR Studio’s Web Demo, which runs in desktop and mobile browsers without installation or registration.

OCR Studio’s Zero-Trust Web Approach to Chilean Documents

OCR Studio brings its ID scanning technology into the browser without transmitting ID images and sensitive data to any external parties. 

The solution provides the coverage and capture capabilities required for both Chilean and international onboarding processes:

• More than 4,000 document templates cover identity documents issued around the world;
• ID OCR supports more than 100 languages and multiple writing systems, including complex scripts;
• Web-Native OCR runs fully on-device in modern desktop and mobile browsers;
• The ID scanner handles real-world images affected by blur, glare, shadows, low resolution, perspective distortion, or an unexpected angle.
• Document-specific templates extract structured fields from ID cards, passports, driver’s licenses, including the data from machine-readable zones, barcodes, and multi-sided documents.

OCR Studio scans supported generations of Chilean identity documents within the same workflow, combines data from both sides of an ID card, and keeps the RUN/RUT separate from the individual card number. For Chile, this coverage is important because businesses may receive both the ID cards and passports introduced in December 2024 and earlier documents that remain valid until they expire.

FAQ

1. What does Zero-Trust Web ID scanning mean?

It means that the browser completes document capture, ID scanning, and data extraction on the user’s device, without trusting any external party. The document image and extracted fields are not sent to third-party providers, crowdsourcing platforms, or human operators. 

2. Which Chilean identity documents can OCR Studio scan?

OCR Studio supports Chilean national ID cards, passports, and driver’s licenses. It can handle current and earlier layouts, read machine-readable zones and barcodes where present, combine fields from both sides of a card, and return the result in a consistent structure.

3. Can the scanner distinguish a RUN or RUT from the ID card number?

Yes. Chilean documents can contain identifiers with different business meanings, and OCR Studio’s document-specific templates distinguish them. The templates keep the RUN/RUT, including its check digit, separate from the individual card number so that each value can be placed in the correct KYC field.

4. How does client-side ID OCR support compliance with Chilean data protection law?

It removes an unnecessary third-party transfer from the ID scanning stage and keeps the full document out of external OCR infrastructure. This supports data minimization, security, and protection by design.

5. Does the customer need to install an application or leave the website?

No. Customers do not need to install an application or leave the website. OCR Studio’s Web SDK runs inside desktop or mobile browsers and can be embedded in the company’s existing onboarding page. Customers can use their device camera or an image file, receive the scan result quickly, and continue in the same KYC process.
