Introduction

Eric Metois is a notable inventor based in Somerville, MA (US), recognized for his contributions to the field of signal processing. With a total of five patents to his name, he has made significant advancements in the methods and apparatuses used for detecting processing stages applied to signals.

Latest Patents

One of his latest patents is titled "Method and apparatus for detecting processing stages applied to a signal." This invention focuses on determining the amount of processing that has been applied to a watermarked signal. The system utilizes a steganographic signal that includes an original signal and an embedded fragile watermark. The fragile watermark is characterized by low energy and high redundancy compared to a robust watermark. The steganographic signal is communicated over a distribution channel to a decoder, which measures the presence of the fragile watermark and estimates its fragility profile. This allows for an assessment of the processing the signal has undergone, which may include A/D and D/A conversions, resampling, and perceptual compression.

Another significant patent by Metois is "Apparatus and method for embedding and extracting information in analog signals using distributed signal features." This invention provides methods for embedding digital data into an analog host signal. It calculates a distributed signal feature of the cover signal in a specific domain and modifies the cover signal accordingly to encode information symbols. The extraction of information symbols is achieved through the reverse process.
