Forensic Science - Encyclopedia of Law and Economics @ 2021-01-01
Forensic science applies natural, physical, and social sciences to resolve legal matters. The term forensics has been attached to many different fields: economics, anthropology, dentistry, pathology, toxicology, entomology, psychology, accounting, engineering, and computer forensics. Forensic evidence is gathered, examined, evaluated, interpreted, and presented to make sense of an event and provide investigatory leads. Various classification schemes exist for forensic evidence, with some forms of evidence falling under more than one scheme. Rules of evidence differ between jurisdictions, even between countries that share similar legal traditions. This makes the sharing of evidence between countries particularly problematic, at times rendering this evidence inadmissible in national courts. Several measures have been proposed and organizations created to strengthen forensic science and promote best practices for practitioners, researchers, and academicians in the field.

Fluorescence Lifetime Imaging - Handbook of Photonics for Biomedical Engineering @ 2021-01-01
Fluorescence lifetime imaging (FLIM) is a key fluorescence microscopy technique to map the environment and interaction of fluorescent probes. It can report on photophysical events that are difficult or impossible to observe by fluorescence intensity imaging, because FLIM is largely independent of the local fluorophore concentration and excitation intensity. Many FLIM applications relevant for biology concern the identification of Förster resonance energy transfer (FRET) to study protein interactions and conformational changes. In addition, FLIM has been used to image viscosity, temperature, pH, refractive index, and ion and oxygen concentrations, all at the cellular level. The basic principles and recent advances in the application of FLIM, FLIM instrumentation, molecular probe, and FLIM detector development will be discussed.

Security and Trust - Secure and Trustworthy Cyberphysical Microfluidic Biochips @ 2020-01-01
Cyberphysical microfluidic biochip (CPMB) designers have enough difficulty simply getting their devices to function and scale. As such, security and trust has not been a major design consideration. However, missteps by related industries suggest that it would be shortsighted to ignore security and trust. This chapter argues for the importance of security and trust designed specifically for CPMBs. First, the factors contributing to the insecurity of CPMBs are discussed and analyzed. Then, a taxonomy of threat models and attack outcomes are described. Extensive example scenarios of microfluidic application areas are provided to vividly illustrate how security and trust issues are already prevalent. The chapter closes by making a strong case for hardware-based security and summarizes the concepts in several tables.

Mitigation: Tamper-Mitigating Routing Fabrics - Secure and Trustworthy Cyberphysical Microfluidic Biochips @ 2020-01-01
Intuitively, a biochip designed for a single function is physically unable to realize an undesired operation. On the other hand, a reconfigurable biochip could be configured in a way that is not only undesirable, but potentially destructive. This chapter introduces the concept of a tamper-mitigating routing fabric, which is a reconfigurable biochip technology that is designed in such a way that the effects of control signal tampering are probabilistically less severe or controlled. Both routing fabric analysis and synthesis techniques are developed and then applied to a DNA barcoding application.
 
A Robust Speech Encryption System Based on DNA Addition and Chaotic Maps - Intelligent Systems Design and Applications @ 2020-01-01
Encryption is one of the most important methods for providing data security mainly for an end to end protection of data transmitted across the networks. In this paper, we proposed a speech encryption algorithm based on DNA addition and chaotic maps for secure speech communication. The algorithm deals with sampled speech signal that is given as input which is divided into four segments of equal duration. During successive levels of iteration, the speech segment is permuted and substituted with different chaotic mapping techniques such as sine mapping, henon mapping, logistic mapping and tent mapping. After performing the permutation and substitution all the segments are combined and encoded as a sequence of DNA’s denoted by X. The DNA sequence X and DNA sequence Y obtained using henon mapping are summed up together using DNA addition operation. Finally, the speech encryption is obtained as the result using DNA decoding. The correlation co-efficient test, Signal to noise ratio test and Peak Signal to Noise Ratio test provides better analysis of the proposed system. The algorithm also provides a better simulation result and also helps in resisting the brute force attacks and differential attacks.
