Title: The Innovative Mind of Walter R. Bender

Introduction

Walter R. Bender, based in Auburndale, MA, is a notable inventor with a remarkable portfolio consisting of nine patents. His innovative work has significantly impacted the fields of data hiding in printed images, showcasing his expertise and creativity in leveraging technology for practical applications.

Latest Patents

Among his latest patents, Bender has developed a "Method and apparatus for data hiding in printed images." This invention introduces a technique for embedding a mark within a printed image, enabling interpretation by an economical printing system. By altering the values of a characteristic parameter in specific portions of the host image, confined to a thread—essentially a small region of contiguous points—this method allows effective embedding without compromising the overall quality of the printed material.

Another significant patent is the "Method and apparatus for multi-bit zoned data hiding in printed images." This technique involves embedding a tracking number as a series of bits within a printed image. Bender's approach alters characteristic parameter values at a set of pseudo-random locations designated for each bit within an embedding zone. The alterations lead to discernible changes in the expectation value of mathematical functions of these values. A marker bit, encoded with higher certainty than others, assists in zone orientation during decoding, enhancing the reliability of tracking number detection through the Patchtrack approach.
