IR Frequency Region: Fingerprint Region

IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the C=O, C=N, and C=C occur between 1600–1850 cm−1.

Double Resonance Techniques: Overview

Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.
Spin decoupling is usually achieved by...

This study enhances biometric encryption security by proposing a new method to prevent known-plaintext attacks on double random phase encoding (DRPE). The technique secures fingerprint data and ensures accurate system verification.

Area of Science:

  • Cryptography
  • Biometrics
  • Image Processing

Background:

  • Double Random Phase Encoding (DRPE) allows biometrics to serve as cipher keys for data encryption.
  • DRPE is susceptible to known-plaintext attacks (KPAs) that can compromise security.

Purpose of the Study:

  • To investigate the vulnerability of DRPE using fingerprints as cipher keys to KPAs.
  • To propose a novel method to prevent KPAs in DRPE-based biometric encryption.

Main Methods:

  • Computational experiments were conducted to assess DRPE's vulnerability to KPAs.
  • A new method was developed that modifies the encrypted image's amplitude component to prevent phase retrieval.
  • The proposed method was tested for its effectiveness in preventing key estimation and fingerprint restoration.
