Scan and Process Image Files with OCR

Optical Character Recognition (OCR) engine extracts text from image files. The Skyhigh Security DLP engine uses best -in-class OCR to extract supported image files. This extracted text is then compared against predefined classification definitions, allowing for the effective classification of content and Data Loss Prevention (DLP) policies can be applied to manage and remediate files as needed. You can use policies and classifications to detect violations and trigger incident alerts. OCR and Classification are available for both Skyhigh Security Service Edge or Skyhigh CASB.

OCR scanning works with all Skyhigh DLP-supported languages and most Western and Asian languages.

Integrating OCR engine in DLP framework allows:

Enhanced DLP Protection. OCR significantly extends DLP protection for sensitive documents including tax paperwork, passports, credit card information, or any other personally identifiable data. This protection extends to images uploaded to the cloud or shared as images including screenshots and handwritten formats, addressing potential vulnerabilities by safeguarding confidential content, even in scenarios where users are restricted from copying and pasting data. 

Evaluation and Compliance. The OCR engine evaluates extracted text based on the match rule criteria defined in the DLP policies. 

• Example 1: When a credit card image is processed, the OCR engine extracts the card number and checks it against the classifications and conditions specified in the DLP policy. This ensures compliance and helps prevent data leaks.
• Example 2: If sections of a design document are encountered as images—whether as standalone images or embedded within another file—the text is extracted and compared against the established fingerprint to detect and prevent data leaks.

Seamless Integration with Existing Policies. No modifications to existing DLP policies are required when utilizing OCR. The established rules, exception criteria, and response rules are applicable to images, ensuring a seamless integration of OCR technology into the DLP framework.

If you purchase the OCR feature, it is enabled by default for Skyhigh Security Service Edge or Skyhigh CASB DLP policies. You can also disable the feature to avoid a slowdown. For details, see Configure OCR.
