Biometrics Takes Off—Fight Between Privacy and Aviation Security Wages On

In the last two decades, the Department of Homeland Security (DHS) has implemented a variety of new screening and identity verification methods in U.S. airports through its various agencies such as the Transportation Security Administration (TSA) and Customs and Border Protection (CBP). In particular, biometric technology has become a focal point of aviation security advances. TSA, CBP, and even private companies have started using fingerprint, iris, and facial scans to verify travelers’ identities, not only to enhance security but also to improve the travel experience. This Comment examines how DHS, its agencies, and private companies are using biometric technology for aviation security. It then considers the most common privacy concerns raised by the expanded use of biometric technology: data breaches, function creep, and data sharing. As biometric technology is new and continually developing, the scope and extent of privacy threats cannot be completely quantified. However, a combination of new legislation, technological solutions, and independent oversight may be an effective way to protect both biometric data and traveler privacy while maintaining the benefits of enhanced security

THE INFRARED SPECTRA OF MATRIX ISOLATED ALKALI METAL HYDROXIDES

Author Institution: National Bureau of Standards, Washington, D.C.The infrared spectra of matrix isolated RbOH, RbOD, NaOH, and NaOD have been observed. Both the alkali metal oxygen stretch, $\nu_{1}$, and the bending mode, $\nu_{2}$, have been assigned for each species. Combination of the results of this study with the microwave measurements for RbOH and RbOD indicates an essentially linear structure for these species. The isotope shift observed for NaOH coupled with reasonable bond lengths indicates an equilibrium configuration of NaOH which probably does not deviate significantly from linearity. These results are consistent with our previously reported results for CsOH

THE REACTION OF LITHIUM WITH CICN: THE INFRARED SPECTRUM OF MATRIX ISOLATED LiCN.

Author Institution: National Bureau of Standards, Washington D.C.The infrared spectra of species obtained from the reactions of lithium atoms with ClCN have been observed in a low temperature argon matrix. With the help of isotopic substitution the spectral features can be interpreted to yield vibrational frequencies of LiCN and LiNC

INFRARED MATRIX SPECTRA OF LITHIUM FLUORIDE.

Author Institution: National Bureau of Standards; National Bureau of Standards, National Institutes of HealthEvidence for a linear dimer $Li_{2}F_{2}$ has been obtained by extending the spectral measurements for matrix isolated lithium fluoride into the far infrared region. The vapors from solid $^{6}LiF, ^{7}LiF$, and $^{6}LiF/^{7}LiF$ mixtures were deposited in argon matrices at liquid hydrogen temperatures. Vibrational assignments were made on the basis of the following linear species: $^{6}Li_{2}F_{2}, ^{7}LiF_{2}, ^{6,7}Li_{2}F_{2}$ and $^{7,6}Li_{2}F_{2}$. Although the specific geometry of the dimer could not be determined, a normal coordinate analysis supported the spectral interpretation of a linear structure $(C_{\infty v})$

INFRARED MATRIX SPECTRA OF CsOH.

Author Institution: National Bureau of StandardsInfrared spectra of matrix isolated CsOH and CsOD have been observed. Vibrational assignments have been made for both species. The results are consistent with a linear model for CsOH and CsOD. Some preliminary data for RbOH will also be presented
