Title: Okan Ersoy: Innovator in Information Security and Imaging Technologies

Introduction

Okan Ersoy is a prominent inventor based in West Lafayette, IN (US), known for his contributions to the fields of information security and imaging technologies. With a total of 8 patents, he has made significant advancements that enhance the efficiency and security of data processing.

Latest Patents

One of his latest patents is titled "Totagraphy: coherent diffractive/digital information reconstruction by iterative phase recovery using reference wave." This innovative process produces a totagram through an iterative spectral phase recovery method, which allows for complete information recovery using special masks and a reference beam. The incorporation of these special masking systems reduces computation time, the number of masks, and the number of iterations required. By adding a reference wave to the iterative process, Okan has improved phase recovery systems and helped prevent phase wrapping. The reference wave is strategically added on-axis to ensure a well-controlled amplitude, enhancing the overall effectiveness of the system.

Another notable patent focuses on "Encryption and decryption using phase recovery." This invention includes methods and systems designed to improve the information security of an input signal. The process involves encrypting the input signal through a series of transformations, which are executed concurrently. Each sequence involves performing a discrete Fourier transform on the input signal while preserving its amplitude information. The input signal is then ciphered based on a unique key corresponding to each sequence, ensuring that the recreation of the input signal requires all encrypted data signals and their respective keys.
