Explainer: What is OCR, and how does it work? | Biometric Update

Optical Character Recognition (OCR) transforms printed text into machine-readable data, solving the inherent limitations of editing and searching image files. This capability is critical in an era of increasing digitalization, where businesses must efficiently process vast amounts of information originally captured on print media. By eliminating manual intervention, OCR enables seamless data conversion, allowing organizations to analyze, store, and manage documents with greater speed and accuracy. The technology functions by scanning documents and using software to distinguish characters from backgrounds through specific algorithms. These systems identify text either by matching patterns against stored fonts or by extracting distinct visual features from glyphs. This automated analysis allows for the precise conversion of visual text into digital formats, supporting the automation of form completion and streamlining operational workflows across various industries without requiring human oversight. This article is highly relevant to open data as it highlights the foundational role of OCR in making unstructured physical records accessible for digital analytics. By converting static images into queryable text, OCR facilitates the integration of traditionally inaccessible information into open datasets. This enhances transparency and efficiency in sectors like biometric identity verification, ensuring that diverse data sources can be uniformly analyzed and shared within open ecosystems.
