August 6, 2020
Location: Access Grid---All SPACT Campuses
The development of novel security materials plays an essential role in fighting against counterfeiting to protect the health, the economy, and national security. The intrinsic advantages of surface enhanced Raman scattering (SERS) technique allow to prepare complicate nanocomposite materials with fingerprint characteristic spectra. These materials can be used as anti-counterfeiting labels which can have high level security information and enormous encoding volume. In this talk, I will first give an introduction on the SERS technique. The main part will be an overview on the recent publications using these SERS labels for anticounterfeiting application. Later, I will also discuss our research activities on the development of anticounterfeiting SERS inks using gold nanostars.

Security Fibers: Strategies for Optimization
July 27, 2020
Location: Access Grid---All SPACT Campuses
Security fibers and planchettes are among the oldest anti-counterfeiting technologies and remain popular today for security paper substrates. However, determining whether security fibers are appropriate for a particular document is only a starting point in the design process, and might even be considered a subordinate question to the design considerations that can support or inhibit the effectiveness of a security fiber implementation, or, equally, the implementation of any security feature technology. This presentation explores considerations for security fiber deployments, to include visible and UV fiber color, shape and size, proprietary and commercial fibers, the role of fibers in substrate uniqueness, user ergonomics and other technology and design variables associated with this class of security feature.

Anti-counterfeiting with Liquid Crystal-Generated Unclonable Patterns
July 27, 2017
Location: Access Grid--All SPACT Campuses
Liquid crystals—well known for their successful commercial application in displays—have unique optical properties, among them the ability to reflect light selectively and dependent on the viewing angle: look at the liquid crystal along one direction and it appears strongly red, tilt the sample and it looks blue. By producing a sample with spheres of such liquid crystal, an intricate pattern can be generated, which changes dynamically as different sample areas are illuminated, and which contains additional hidden information thanks to its well-defined polarization state. Moreover, since the spheres are arranged in a random fashion, we believe that each pattern is unique in a way that is out of control of the producer, to the extent that even the manufacturer of the original would not be able to make a copy. In an interdisciplinary research thrust at the University of Luxembourg, involving computer and materials scientists, we are exploring the potential of using such liquid crystal sphere samples for secure authentication tokens, which can be produced at high throughput at low cost and be integrated into valuable objects to prove their authenticity. In the presentation, the basic principles of the technique and the current state of the research will be presented.

On the forensic contribution of micro-Raman spectroscopy to the chemical characterization of inkjet printer inks—an investigative approach
July 20, 2017
Location: Access Grid---All SPACT campuses
The application of micro Raman spectroscopy to characterize and discriminate colored inkjet printer inks is discussed. From a forensic science perspective, spectroscopic data are typically obtained to evaluate similarities between questioned specimens and reference samples to address questions about their source. Suspected objects (i.e., printers) are not always available to conduct such comparative examinations. In this project, the potential of the Raman technique is explored to evaluate its suitability to produce investigative leads in cases where a suspected printer needs to be developed. The factors that make such an approach successful for an investigative goal will be discussed. The Criminal Investigative Division, Treasury Obligations Section of the United States Secret Service, provided the samples for this study. In the context of their investigations on counterfeited banknotes, USSS specialists have observed that more than 60% of all counterfeit banknotes are produced using this inkjet printing technology. The overall goal is to investigate if Raman data gathered from the three microscopic colored spots (i.e., cyan, magenta, and yellow) of inkjet printed documents constitute, all together, a chemical signature sufficiently discriminating to provide reliable investigative leads in a time-effective and non-destructive manner. During this research it is expected to develop a statistical approach that can be reliably and objectively differentiate between samples from different sources based on minor spectral differences and to evaluate if different color spots from the same source can be treated as independent pieces of information. This study will also compare to the traditional method of thin layer chromatography to inform questioned document examiners about the complementarities between the two approaches.

Application of Functional Data Analysis to Chemical Data ~ Comparison, Classification and Database Search of Forensic Ink Chromatograms
July 9, 2015
Location: Access Grid All SPACT campuses
Ink examination is used in a variety of criminal investigations. Types of ink examination include identification, comparison, and dating. In this presentation, we concentrate on the identification and comparison of ink samples. Identifying ink samples is a very complex problem. Not only are there many types of inks in existence, but ink with the same formula can be used in multiple models of pens from multiple brands and manufacturers. Other problems can affect the comparison between ink samples, such as the degradation of ink samples due to time and other environmental factors.
Mathematical algorithms have already been developed to automatically compare an ink sample with other samples in a database with the goal of determining the brands, models, and years of manufacture of pens that could have produced the sample. Most often these algorithms assume some multivariate distribution of the ink characteristics and use some data reduction technique to show that inks can be differentiated in quasi-ideal situations. In this presentation, we propose a new approach to mathematically describe ink samples using functional data analysis. This method does not make any assumption on the data and can account for less than ideal samples.
Functional data analysis is a fairly new statistical method which deals with data of functional nature. Such data often arises during chromatographic or spectroscopic analysis of material of forensic interest, where the data is represented as a function of time. In this particular case, we characterize the chromatograms of ink samples produced by High Performance Thin Layer Chromatography as functions of time and wavelength. We built and tested several algorithms to register multiple ink samples that were analyzed at different times, or by different analysts, into a common space, compare ink samples using a metric of similarity, and to use these comparisons to cluster large databases of inks. Our algorithms can readily be implemented to search an unknown ink sample and retrieve a list of ink samples most similar to the ink sample in question. Finally, we note that similar algorithms can be developed for most forensic chromatographic or spectroscopic applications.

With the Increasing Incidence of Counterfeiting and Simulation of Goods, Why is it so Hard to Sell Security?
April 17, 2015
Location: Access Grid (all SPACT campuses)
Law enforcement and border management agencies around the world have clearly demonstrated the increasing incidence of both counterfeiting and simulation of material goods. The financial impact of these is enormous, as is the risk to product brands. Despite this evidence, product manufacturers and brand owners remain a difficult sell when it comes to incorporation of security features into product of packaging.
I will discuss some of the factors that contribute to this apparent conundrum from both sides of the issue – as a technical leader in a security business and as a technical leader of a product business, both within 3M. While I don’t pretend to have the answers to all questions, I hope to convey information that will help build an understanding of the business issues and therefore help the SPACT team plan to address the business issues as they address the technical issues when developing security solutions.

Touchscreen-based User Authentication Using Hand Biometrics
March 6, 2015
Location: Access Grid (all SPACT campuses)
User authentication plays an indispensable role in protecting computer systems and applications, but the development of touchscreen hardware and the user habit change post requirements for new authentication methods. Based on an extensive study of touchscreen hardware and biometric patterns, we present a robust user authentication scheme using biometric features of touch gestures. Discriminative features are extracted from the touch-point data, and used in statistical analysis for verification. We tested our scheme in a variety of experiments that involved multiple volunteers to perform various gestures. The analysis of experimental results and user feedback indicate that the new scheme delivers comprehensive measurements and accurate pattern classification for user authentication.

Hansen Solubility Parameters for Development of Optically Variable Security Inks
November 7, 2014
Location: Access Grid (all SPACT campuses)
Modern security inks incorporate nanoparticles with novel properties to increase the complexity of a security ink for the purpose of preventing counterfeit production. Typically the nanoparticles used are dispersed in a polymer matrix to form a mechanically robust device while maintaining the unique properties of said nanoparticles. Dispersing nanoparticles in a given ink has typically relied on generically matching the polarity of the nanoparticle capping agent to that of the polymer and solvents used to print the ink. This research focused on identifying a quantitative approach to dispersing nanoparticles through characterizing the Hansen Solubility Parameters (HSPs) of various nanoparticles synthesized for security inks. Once HSPs were obtained, solvents and polymers were chosen to form an optimal security ink. The printed nanoparticle film microstructure was varied by controlling the ink HSPs throughout evaporation to form continuous, discontinuous, and disrupted film microstructures. Finally, an optically variable ink was produced as a proof of concept.

Porous Wall Hollow Glass Microspheres…..New Materials for New Applications in Energy, Environmental Remediation, Defense and Medicine
September 18, 2014
Location: Access Grid: All SPACT Campuses
A new class of materials, called Porous Wall Hollow Glass Microspheres (PWHGMs), was developed at the Savannah River National Laboratory. These tiny glass micro-balloons are about one-half the diameter of a human hair and can range in size from 2 to 100 microns. The thin outer shells are about one micron thick and what makes these microspheres one-of-a-kind is that the team has been able to induce and control an interconnected, through-wall porosity, on a scale of 100 to 1,000 Angstroms. This porosity is then used to fill the microspheres with a variety of materials, including solids, liquids and gases, which result in unique composites having a variety of unique properties. This microsphere technology has been involved in more than a dozen different programs and applications in areas of energy, environmental remediation, defense and in medicine. PWHGMs have been patented, licensed, and are now being advanced for commercialization in various areas and disciplines, at the Applied Research Center of SC.

Photon Activation Analysis and its Potential Forensic, Authentication and Security Applications
July 30, 2014
Location: Access Grid: All SPACT campuses
Nuclear activation analysis using neutrons, charged particles and photons has a long history, with many applications in environmental, cultural and forensic disciplines. Each has their respective relative advantages, depending on the application. In the case of photons from electron-beam bremsstrahlung, advantages which may enable forensic and materials/parts authentication and security applications. These include (a) high penetrability, enabling analysis of
larger objects that are nearly uniformly activated, (b) non-destructive analysis of high-value or irreplaceable objects and materials, (c) production of shorter activation half-lives that enable more rapid return of objects and materials to their owners and (d) highly-directional beams that could readily function in industrial settings. These particular advantages have only been partially exploited. There remain many important applications that have never been fully explored or exploited. Among these are (i) industrial, criminal and arms-control forensics, (ii) authentication applications in medicine and industry, (iii) provenance applications archaeology, paleontology and museum sciences, (iv) contraband attribution and interdiction, (v) mining and hazardous/precious waste assay, (vi) environmental studies in pollution fate and transport and (vii) nuclear non-proliferation. This talk will focus on opportunities and potential of some these applications and the state of the art in these areas.

Security Printing Technologies, Competing with Zero
July 15, 2014
Location: Access Grid: All SPACT campuses
Security Printing technologies are enabled by variable data printing (VDP) available on all modern presses. When considering any security printing approach, you must be ready to potentially compete with zero—that is, zero incremental cost for security. The broad set of VDP based security printing approaches will be outlined in this talk, along with the ecosystem in which they function. I will show that zero cost is not always the optimum solution.

Multimedia Authentication and Forensics
February 14, 2014
Location: Access Grid (all SPACT campuses)
Product counterfeiting is a well-known problem, which has done significant damage to the production and distribution of physical goods for a very long time. In the past decade, the use of multimedia applications has significantly increased because of the advance in network bandwidth and storage capacity, and the use of smartphone makes rich-content applications further penetrate into daily life. Due to the ubiquitous availability of editing software for digital media, manipulation skills of digital media have been simplified and spreading extensively, which weakens our traditional trust to the integrity of digital media. Nowadays, forgery and piracy have become the major challenges to the applications of digital media. Therefore, various types of technologies have been developed to protect both physical and virtual products and counteract these growing threats. In this talk, I will introduce some vulnerabilities and potential attacks on digital media, and then discuss some mainstream approaches to authenticate digital media and protect its integrity. Furthermore, I will also talk about the some digital forensic research on analysis of fake and tampered media to reveal some trace and evidence for law enforcement and justice. Although this talk will mainly focus on digital media, some discussed solutions are also applicable to printed labels and tags.
