Showcase Initiates Testing of Advanced Masking Technology Using LLM in ProTech AI-OCR

Showcase Introduces Next-Generation Masking Technology



In a bid to enhance its image analysis service, ProTech AI-OCR, Showcase, a company based in Minato, Tokyo, has announced the commencement of a proof-of-concept for a cutting-edge masking technology that incorporates large language models (LLM). This innovative approach aims to significantly improve the accuracy of data masking for sensitive information contained within various documents.

ProTech AI-OCR utilizes AI-driven machine learning to automatically mask personal and confidential information found in documents. Previously, when the masking accuracy was insufficient, the company would individually train new patterns to enhance this accuracy. However, with diversifying document formats specific to each municipality and business, as well as the need for context-based information judgment, the conventional learning-based OCR faced notable challenges.

To address these issues, Showcase has focused on research and development utilizing LLMs, which enhance the capability to understand context in information identification and masking. As a result, they have achieved a solution that can accurately mask unstructured documents, overcoming the limitations of prior methods. Their technology has demonstrated the ability to automatically mask a wide array of information with high accuracy, regardless of document format or image quality.

Currently, this innovative technology is being tested in select municipalities, specifically for masking purposes related to credit card numbers, to streamline operations and elevate information management strategies. Showcase aims to further improve precision and expand the application scope of this technology, promoting efficient and secure information management solutions across diverse sectors.

Beyond Text Recognition: The Power of ProTech AI-OCR


ProTech AI-OCR isn’t just limited to text parsing; it can accurately read and digitize text from a variety of image types, including identification documents like driver's licenses, business cards, receipts, and handwritten forms such as application and medical questionnaires, achieving over 99% accuracy. This automation of traditionally labor-intensive data entry processes reduces operational time and costs.
