description: The chemical properties of high-z galaxies provide important information to constrain galaxy evolutionary scenarios. However, widely-used metallicity diagnostics based on rest-frame optical emission lines are not usable for heavily dust-enshrouded galaxies (such as Sub-Millimeter Galaxies; SMGs), especially at z>3. Here we focus on the flux ratio of the far-infrared fine-structure emission lines [NII]205um and [CII]158um to assess the metallicity of high-z SMGs. Through ALMA cycle 0 observations, we have detected the [NII]205um emission in a strongly [CII]-emitting SMG, LESS J033229.4-275619 at z=4.76. The velocity-integrated [NII]/[CII] flux ratio is 0.043 +/- 0.008. This is the first measurement of the [NII]/[CII] flux ratio in high-z galaxies, and the inferred flux ratio is similar to the ratio observed in the nearby universe (~0.02-0.07). The velocity-integrated flux ratio and photoionization models suggest that the metallicity in this SMG is consistent with solar, implying the chemical evolution has progressed very rapidly in this system at z=4.76. We also obtain a tight upper limit on the CO(12-11) transition, which translates into CO(12-11)/CO(2-1) <3.8 (3 sigma). This suggests that the molecular gas clouds in LESS J033229.4-275619 are not affected significantly by the radiation field emitted by the AGN in this system.

Charge and orbital order in frustrated Pb3Mn7O15
Creators: name: Kimber, Simon A. J.
Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: The candidate magnetoelectric Pb3Mn7O15 has a structure consisting of 1/3 filled Kagome layers linked by ribbons of edge-sharing octahedra in the stacking direction. Previous reports have indicated a complex hexagonal-orthorhombic structural transition upon cooling to room temperature, although its origins are uncertain. Here both structures are revisited using a combination of neutron and synchrotron X-ray diffraction data. Large shifts of oxygen positions are detected which show that the interlayer sites and those which occupy voids in the kagome lattice are trivially charge ordered in both phases. The symmetry breaking is found to occur due to Mn3+ orbital ordering on the ribbon sites and charge ordering of the sub-set of layer sites which make up a Kagome network.

The governance of failure: An anatomy of corporate bankruptcy in Japan

description: The broad trade-offs facing bankruptcy policy are, of course, not uniquely American. In this paper, we survey the Japanese corporate bankruptcy system, and present a comprehensive empirical analysis as to how it works in practice. Our framework for analysis is a variation on a theme of transaction cost economics: instruments of bankruptcy policy should effect a discriminating alignment between firms and the institutions governing failure, one which grants the services of legally centralized recontracting to those cases that warrant it, while maintaining incentive-intensity in private ordering for the others. (Williamson, 1985; 1989) This paper, through the examination of bankruptcy statistics, and the analysis of bankruptcy laws, courts and other institutions governing business failure in Japan, presents the Japanese system as a case study of corporate bankruptcy policy and institutional design.

description: The paper gives an artificial neural network (ANN) approach to time series modeling, the data being instance versus notes (characterized by pitch) depicting the structure of a North Indian raga, namely, Bageshree. Respecting the sentiments of the artists' community, the paper argues why it is more ethical to model a structure than try and "manufacture" an artist by training the neural network to copy performances of artists. Indian Classical Music centers on the ragas, where emotion and devotion are both important and neither can be substituted by such "calculated artistry" which the ANN generated copies are ultimately up to.

The obtained results are in good agreement with experimental facts collected on herbertsmithite ZnCu3(OH)6Cl2 and on heavy-fermion metals, and allow us to predict a new scaling in magnetic fields in the dynamic susceptibility. Under the application of strong magnetic fields quantum spin liquid becomes completely polarized. We show that this polarization can be viewed as a manifestation of gapped excitations when investigating the spin-lattice relaxation rate.

description: The Catalogue of Wooden Figures is the first of a series of online catalogues aimed at presenting the corpus of wooden, stone and bronze sculptures kept in the Collection of Egyptian Antiquities of the Museum of Fine Arts, Budapest. Although scholarly research has been continuously carried out on the highlights of the collection since the 1940s, and results have been regularly published in the Bulletin du Musée Hongrois des Beaux-Arts, and recently in Egyptian Artefacts of the Museum of Fine Arts Budapest (2013), a comprehensive study has not yet been completed on the subject.

Along with launching this online series, the Department of Egyptian Antiquities intends to create an open-access, easily searchable database of the catalogued object groups. In addition to the basic data of the objects (inv. no., photo, object name, measures, material and condition, description, classification/function, date, origin, provenance, bibliography, analogies/parallels), a short description (using keywords) and the full bibliography of the objects are also included. Furthermore, the objects are classified according to their most probable original context in which they had been used in Antiquity (Classification/Function). Each catalogue item is supplemented with a list of analogies/parallels found in printed publications or on various websites of Egyptian collections.
The collaboration with Dr. Éva Liptay, Chief Curator, started in 2012; in particular I studied the collection of Osiris and Ptah-Sokar-Osiris figures and contributed as a subject matter expert and consultant to the catalogue.

description: AdS5 X S5 and its pp-wave limit are self-dual under transformations involving eight fermionic T-dualities, a property which accounts for symmetries seen in scattering amplitudes in N=4 super-Yang-Mills. Despite strong evidence for similar symmetries in the amplitudes of three-dimensional N=6 ABJM theory, a corresponding self-duality in the dual geometry AdS4 X CP3 currently eludes us. Here, working with the type IIA pp-wave limit of AdS4 X CP3 preserving twenty four supercharges, we show that the pp-wave is self-dual with respect to eight commuting fermionic T-dualities and not the six expected. In addition, we show the same symmetry can be found in a superposition pp-wave and a generic pp-wave with twenty and sixteen unbroken supersymmetries respectively, strongly suggesting that self-duality under fermionic T-duality may be a symmetry of all pp-waves.

Herd Behavior, the "Penguin Effect", and the Suppression of Informational Diffusion: An Analysis of Informational Externalities and Payoff Interdependency
Creators: name: Choi, Jay Pil
Publisher: name: Columbia University
Year: 1994
Subjects: Economics

description: This paper analyzes a technology adoption process in which the effect of informational spillover interacts with network externalities. It is shown that the interplay of informational externalities and payoff interdependency induces risk averse and clustering behavior in the technology adoption process. our analysis differs from the herd behavior literature in focusing on how the herd behavior of subsequent users influences the initial adoption decision. The mechanism through which herd behavior is generated is also quite different. herd behavior in this paper stems from each agent's desire to inhibit the revelation of new information which can be used in a way detrimental to her, rather than from each others agent's effort to free -ride on information contained in the decisions made by predecessors. Finally, the model suggests a new perspective on standard-setting committees. Their role is to limit deliberately the effects of information flows, rather than to serve as a forum for exchange of information and negotiation.

The anatomy of a memory : insights into how information is stored in the brain

description: How we learn and remember are questions that have been central to three intellectual disciplines: philosophy, psychology and biology. Until the nineteenth century, the study of learning and memory was restricted largely to the domain of philosophy. Later, this theoretical approach was gradually replaced by more experimental studies, initially in psychology and then in biology. The questions posed by these two disciplines concerning learning and memory storage began to converge, and today psychologists and biologists have joined forces to open up the “black box” to study how the brain and behavior allows us to learn and have memories.
Metamorphic Runtime Checking of Non-Testable Programs
Creators: name: Murphy, Christian
name: Kaiser, Gail E.
Publisher: name: Columbia University
Year: 2009
Subjects: Computer science

description: Challenges arise in assuring the quality of applications that do not have test oracles, i.e., for which it is difficult or impossible to know that the correct output should be for arbitrary input. Recently, metamorphic testing has been shown to be a simple yet effective technique in addressing the quality assurance of these so-called "non-testable programs". In metamorphic testing, existing test case input is modified to produce new test cases in such a manner that, when given the new input, the function should produce an output that can easily be computed based on the original output. That is, if input x produces output f(x), then we create input x' such that we can predict f(x') based on f(x); if the application does not produce the expected output, then a defect must exist, and either f(x) or f(x') (or both) is wrong. Previously we have presented an approach called "Automated Metamorphic System Testing", in which metamorphic testing is conducted automatically as the program executes. In the approach, metamorphic properties of the entire application are specified, and then checked after execution is complete. Here, we improve upon that work by presenting a technique in which the metamorphic properties of individual functions are used, allowing for the specification of more complex properties and enabling finer-grained runtime checking. Our goal is to demonstrate that such an approach will be more effective than one based on specifying metamorphic properties at the system level, and is also feasible for use in the deployment environment. This technique, called Metamorphic Runtime Checking, is a system testing approach in which the metamorphic properties of individual functions are automatically checked during the program's execution. The tester is able to easily specify the functions' properties so that metamorphic testing can be conducted in a running application, allowing the tests to execute using real input data and in the context of real system states, without affecting those states. We also describe an implementation framework called Columbus, and present the results of empirical studies that demonstrate that checking the metamorphic properties of individual functions increases the effectiveness of the approach in detecting defects, with minimal performance impact.

Do Converters Facilitate the Transition to a New Technology?: A Dynamic Analysis of Coverters
Creators: name: Choi, Jay Pil
Publisher: name: Columbia University
Year: 1994
Subjects: Economics

description: This paper analyzes the process of transition in standards between incompatible technologies when converters are available. Contrary to a common presumption that converters facilitate the transition from an old technology to an otherwise incompatible new technology, I find circumstances in which the possibility of transition is blockaded by the existence of converters. When there are changes in the adoption behavior due to the existence of converters, I also analyze the welfare consequences of the changes in the adoption regimes. In the welfare analysis of converters, a distinction is made between ex ante and ex post efficiency.

description: Single crystal neutron diffraction studies have been performed on the S = 3/2 kagome staircase compound Co3V2O8 with a magnetic field applied along the magnetization easy-axis (H || a). Previous zero field measurements [Y. Chen, et al., Phys. Rev. B 74, 014430 (2006)] reported a rich variety of magnetic phases, with a ferromagnetic ground state as well as incommensurate, transversely polarized spin density wave (SDW) phases (with a propagation vector of k = (0 delta 0)) interspersed with multiple commensurate lock-in transitions. The magnetic phase diagram with H || a adds further complexity. For small applied fields, H = 0.05 T, the commensurate lock-in phases are destabilized in favor of the incommensurate SDW, while slightly larger applied fields restore the commensurate lock-in phase with delta = 1/2 and yield a new commensurate phase with delta = 2/5. For all measurements in an applied field, higher-order scattering is observed that corresponds to the second-harmonic.

First principle study of the thermal conductance in graphene nanoribbon with vacancy and substitutional silicon defect

description: The thermal conductance in graphene nanoribbon with a vacancy or silicon point defect (substitution of C by Si atom) is investigated by non-equilibrium Green's function (NEGF) formalism combined with first-principle calculations density-functional theory with local density approximation. An efficient correction to the force constant matrix is presented to solve the conflict between the long-range character of the {\it ab initio} approach and the first-nearest-neighboring character of the NEGF scheme. In nanoribbon with a vacancy defect, the thermal conductance is very sensitive to the position of the vacancy defect. A vacancy defect situated at the center of the nanoribbon generates a saddle-like surface, which greatly reduces the thermal conductance by strong scattering to all phonon modes; while an edge vacancy defect only results in a further reconstruction of the edge and slightly reduces the thermal conductance. For the Si defect, the position of the defect plays no role for the value of the thermal conductance, since the defective region is limited within a narrow area around the defect center.

The Philosophy of Locational Competition
Creators: name: Findlay, Ronald E.
Publisher: name: Columbia University
Year: 1994
Subjects: Economics

description: "While Standortswettbewerb may be a familiar term in the German economics literature, with a long tradition in location theory going back to von Thunen and Losch, its English counterpart "locational competition" does not ring any bells, at least to me. One possible meaning, it would seem, is the choice of sites by firms at which to locate various production or marketing facilities to maximize their profits, given what their competitors are doing. It would thus constitute the geographical dimension of competition between oligopolists and as such would bring into play the full panoply of the location theorist's exotic arsenal of hexagons, isodapones, and whatever else have you. Somehow I do not think that this is what Professor Horst Siebert had in mind when he invited me to write a paper on this subject, which is the theme of our conference. What he appears to want us to understand by this phrase is rather competition between nations, not firms, to attract within their borders as much as possible of global pools of internationally mobile factors, thus raising the incomes of complementary immobile factors confined within those borders. In any case, this is the sense in which I will interpret the term in this paper."

description: The first part of this paper is concerned with uniqueness to inverse time-harmonic elastic  scattering from bounded rigid obstacles in two dimensions. It is proved that a connected polygonal obstacle can be uniquely identified by the far-field pattern  corresponding to a single elastic plane wave. Our approach is based on a new reflection principle for the first boundary value problem of the Navier equation.  In the second part, we propose a revisited factorization method to recover a rigid elastic body with a single far-field pattern.
Kinematic patterning of flaps, taps and rhotics in English
Creators: name: Derrick, Donald
Publisher: name: University of British Columbia
Year: 2011

description: Psychological researchers have found evidence for speech planning down to the syllable, with some evidence for planning at the level of the phoneme (Levelt, 1989) or feature (Bernhardt and Stemberger, 1998). Speech scientists who examine coarticulation argue for no speech planning (Saltzman and Munhall, 1989), or limited planning (Whalen, 1990). I provide evidence for subphonemic speech planning based on B/M ultrasound to measure tongue shape and motion, identifying four categorical variants of flap/- taps (‘T’) in North American English, [alveolar taps ([ɾ↕]), down-flaps ([ɾ↘]), up-flaps ([ɾ↖]), and postalveolar taps ([ɾ⃡])], and two broad categories of rhotic vowels (‘R’) [tongue tip-up rhotics ([ɻ̩]) and tongue tip-down rhotics ([ɹ̩])], even across repetitions of the same utterance in identical phonetic contexts. I explain the pattern of variation in terms of hypothesized constraints on rapid articulation. These include articulatory conflicts (Gick and Wilson, 2006) between segments that require an articulator to be in two places at once, and the end-state comfort effect (Rosenbaum et al., 1992), where an articulator begins a complex sequence in an awkward position in order to end comfortably. Speakers who can repeat syllables quickly are more likely to avoid articulatory conflicts during normal speech production. Speakers who repeat syllables more slowly produce ‘T’ variants involving fewer changes in motion, sometimes forcing non-rhotic vowels in the middle of ‘T’ sequences to become rhotacized in exchange for canonical vowels at the end. These results provide evidence for planning across syllable, morpheme and word boundaries. Other hypothesized constraints on speech planning such as gravity and tissue elasticity are also examined, and demonstrate a mismatch between the number of distinct articulatory actions and the number of phoneme units in a given speech sequence. The results support a theory of subphonemic speech planning that takes into account potential upcoming articulatory conflicts, a person’s motor skills, and the effects of gravity and elasticity.
A Case Study in Distributed Deployment of Embedded Software for Camera Networks

description: We present an embedded software application for the real-time estimation of building occupancy using a network of video cameras. We analyze a series of alternative decompositions of the main application tasks and profile each of them by running the corresponding embedded software on three different processors. Based on the profiling measures, we build various alternative embedded platforms by combining different embedded processors, memory modules and network interfaces. In particular, we consider the choice of two possible network technologies: ARCnet and Ethernet. After deriving an analytical model of the network costs, we use it to complete an exploration of the design space as we scale the number of video cameras in an hypothetical building. We compare our results with those obtained for two real buildings of different characteristics. We conclude discussing the results of our case study in the broader context of other camera-network applications.
Competition Among Institutions

Publisher: name: Columbia University
Year: 1992
Subjects: Economics

description: Economic theory offers two different approaches to the analysis of group formation and the role of institutions. The general equilibrium approach explores the influence of the economic environment on the formation of groups. The game theoretic approach runs in the opposite direction; it explores the influence of institutions on economic outcomes. To integrate these approaches we consider situations in which institutions must compete for members. Our focus is on the fundamental interaction between memberships and policies. The policy that an institution adopts depends on its membership, while its membership depends on the policies of all the institutions. We provide the basic elements for a theory of competition among institutions: an abstract definition of an institution and the corresponding equilibrium concepts. We demonstrate by example, the possibility that equilibrium may not exist. In the absence of a general existence result, we pursue three different avenues. We begin with existence results based on maximization of a utilitarian social welfare function. This places strong restrictions on the decision-making process, although it covers a number of interesting political applications. This is followed by a continuity-based approach. Although quite general, it relies critically on an assumption that the institutions have certain idiosyncratic features. To handle cases without idiosyncrasies, we turn to an algebraic approach. Although existence is established, the result depends on the dimensionality of the problem. Together, these avenues provide a broad class of models for which equilibrium exists, covering cases with multiple dimensions, multiple institutions, and general institutional decision-making processes.
International Emission Permits: Equity and Efficiency

description: Not all possible distributions of a given total of emission permits are compatible with the attainment of first-best Pareto efficiency. In fact, of the infinitely many ways of distributing a given total of permits between a fixed number of parties, only a finite number can lead to efficiency. We can therefore evaluate permit allocations not only in terms of their equity, but also in terms of their efficiency. If there are no other redistributive instruments in the policy environment, the traditional orthogonality of equity and efficiency does not hold here. This has important implications for arguments about the initial international distribution of entitlements to produce carbon dioxide.
Different types of the dimensional crossover in the quasi-one-dimensional spinless fermion systems

Year: 2011
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: It is known that many-body correlations qualitatively modify the properties of a one-dimensional metal. However, for a quasi-one-dimensional metal these correlations are suppressed, at least partially. We study conditions under which the one-dimensional effects significantly influence the dimensional crossover of a quasi-one-dimensional metal. It is proved (i) that even a system with very high anisotropy of the single-particle hopping might behave on both sides of the crossover as an ordinary weakly non-ideal Fermi gas. Further, (ii) to demonstrate well-developed signatures of one-dimensional correlations the system must have extremely (exponentially) high anisotropy. Between cases (i) and (ii) an intermediate regime lies: (iii) the one-dimensional phenomena affect the two-particle susceptibilities, but do not reveal themselves in single-particle quantities. Unlike the normal state properties, (iv) the ordering transition is always very sensitive to the anisotropy: the mean field theory quickly becomes invalid as the anisotropy increases. An expression for the transition temperature is derived. The attributes (i-iv) are used to classify the weakly interacting quasi-one-dimensional fermion systems.

description: In borocarbide ErNi$_2$B$_2$C the phase transition to the commensurate spin density wave at 2.3 K leaves 1/20 part of Ising-like Er spins practically free. Vortices polarize these spins nonuniformly and repolarize them when moving. At a low spin relaxation rate and at low bias currents vortices carrying magnetic polarization clouds become polaron-like and their velocities are determined by the effective drag coefficient which is significantly bigger than the Bardeen-Stephen (BS) one. As current increases, at a critical current $J_c$ vortices release polarization clouds and the velocity as well as the voltage in the I-V characteristics jump to values corresponding to the BS drag coefficient. The nonuniform components of the magnetic field and magnetization drop as velocity increases resulting in weaker polarization and discontinuous dynamic dissociation depinning transition. As current decreases, on the way back, vortices are retrapped by polarization clouds at the current $J_r

description: This paper uses pooled 1971, 1981, and 1986 Canadian census data to evaluate the extent to which (1) the earnings of Canadian immigrants at the time of immigration fall short of the earnings of comparable Canadian-Born Individuals, and (2) immigrants' earnings grow more rapidly over time than those of the Canadian-born. Variations in the labor market assimilation of immigrants according to their gender and country of origin are also analyzed. The results suggest that recent immigrant cohorts have had more difficulty being assimilated into the Canadian labor market than earlier ones, an apparent consequence of recent changes in Canadian immigration policy, labor market discrimination against visible minorities, and the prolonged recession of the early 1980s.

US-Japan trade friction and its dilemmas for US policy

description: Trade frictions between the United States and Japan go back well over a century. While the form and substance of these problems have changed significantly since the time of Commodore Perry, the size and technological dynamism of the contemporary Japanese economy present US policymakers with a unique set of challenges. Bergsten and Noland (1993) group these challenges into four categories: microeconomic, structural, macroeconomic, and systemic. The focus of this paper is on the policy problems posed by the microeconomic and structural differences in the two economies, both because these are the most controversial intellectually and well and the most sensitive politically, at least in the United States. Moreover, this paper is exclusively on the Japan-related aspects of these problems, for reasons of both brevity and the presumed interests of the audience of this volume. This is certainly not to say that policies and practices in Japan are the source of all of the problems in the bilateral relationship: a persuasive case can probably be made that much of the tension in the bilateral relationship stems from anxiety in the US over declining competitiveness which is largely a domestic issue. Nonetheless, this paper focuses on Japan-related concerns. The structure of the paper is to first examine the issue of Japanese uniqueness (which provides the justification for a Japan-specific policy), then evaluates the significance of this issue for the US economy. The paper then moves toward a more normative analysis, examining possible alternative policy approaches, and concludes with a discussion of current US policy toward Japan.

description: We consider a random graph G(n,p) whose vertex set V has been randomly embedded in the unit square and whose edges are given weight equal to the geometric distance between their end vertices. Then each pair {u,v} of vertices have a distance in the weighted graph, and a Euclidean distance. The stretch factor of the embedded graph is defined as the maximum ratio of these two distances, over all u,v in V. We give upper and lower bounds on the stretch factor (holding asymptotically almost surely), and show that for p not too close to 0 or 1, these bounds are best possible in a certain sense. Our results imply that the stretch factor is bounded with probability tending to 1 if and only if n(1-p) tends to 0, answering a question of O'Rourke.

description: In this communication with computer simulation we evaluate simple cubic random-site percolation thresholds for neighbourhoods including the nearest neighbours (NN), the next-nearest neighbours (2NN) and the next-next-nearest neighbours (3NN). Our estimations base on finite-size scaling analysis of the percolation probability vs. site occupation probability plots. The Hoshen--Kopelman algorithm has been applied for cluster labelling. The calculated thresholds are 0.1372(1), 0.1420(1), 0.0976(1), 0.1991(1), 0.1036(1), 0.2455(1) for (NN + 2NN), (NN + 3NN), (NN + 2NN + 3NN), 2NN, (2NN + 3NN), 3NN neighbourhoods, respectively. In contrast to the results obtained for a square lattice the calculated percolation thresholds decrease monotonically with the site coordination number z, at least for our inspected neighbourhoods.

description:
Water is an essential nutrient that has primarily been considered in terms of its physiological necessity. But reliable access to water in sufficient quantities and quality is also critical for many nutrition-related behaviors and activities, including growing and cooking diverse foods. Given growing challenges to water availability and safety, including climate change, pollution, and infrastructure degradation, a broader conceptualization of water and its diverse uses is needed to sustainably achieve global nutrition targets. Therefore, we review empirical and qualitative evidence describing the linkages between water security (the reliable availability, accessibility, and quality of water for all household uses) and nutrition. Primary linkages include water security for drinking, food production and preparation, infant and young child feeding, and limiting exposure to pathogens and environmental toxins. We then identify knowledge gaps within each linkage and propose a research agenda for studying water security and nutrition going forward, including the concurrent quantification of both food and water availability, accessibility, use, and stability. By making explicit the connections between water security and nutritional well-being, we aim to promote greater collaboration between the nutrition and water, sanitation, and hygiene sectors. Interdisciplinary policies and programs that holistically address the water-nutrition nexus, versus those that focus on water and nutrition independently, are likely to significantly advance our ability to ensure equitable access to healthy foods and safe water for all.

description: Statistical inference is often simplified by sample-splitting. This simplification comes at the cost of the introduction of randomness that is not native to the data. We propose a simple procedure for sequentially aggregating statistics constructed with multiple splits of the same sample. The user specifies a bound and a nominal error rate. If the procedure is implemented twice on the same data, the nominal error rate approximates the chance that the results differ by more than the bound. We provide a non-asymptotic analysis of the accuracy of the nominal error rate and illustrate the application of the procedure to several widely applied statistical methods.

description: We discuss entanglement and critical properties of the spin-3/2 XXZ chain in its entire gapless region. Employing density-matrix renormalization group calculations combined with different methods based on level spectroscopy, correlation functions and entanglement entropies, we determine the sound velocity and the Luttinger parameter of the model as a function of the anisotropy parameter. Then, we focus on entanglement properties by systematically studying the behavior of Rényi entropies under both open and periodic boundary conditions, providing further evidence of recent findings about entanglement entropies of excited states in conformal field theory.

F3ildCrypt: End-to-End Protection of Sensitive Information in Web Services

description: The frequency and severity of recent intrusions involving data theft and leakages has shown that online users' trust, voluntary or not, in the ability of third parties to protect their sensitive data is often unfounded. Data may be exposed anywhere along a corporation's web pipeline, from the outward-facing web servers to the back-end databases. Additionally, in service-oriented architectures (SOAs), data may also be exposed as they transit between SOAs. For example, credit card numbers may be leaked during transmission to or handling by transaction-clearing intermediaries. We present F3ildCrypt, a system that provides end-to-end protection of data across a web pipeline and between SOAs. Sensitive data are protected from their origin (the user's browser) to their legitimate final destination. To that end, F3ildCrypt exploits browser scripting to enable application- and merchant-aware handling of sensitive data. Such techniques have traditionally been considered a security risk; to our knowledge, this is one of the first uses of web scripting that enhances overall security. F3ildCrypt uses proxy re-encryption to re-target messages as they enter and cross SOA boundaries, and uses XACML, the XML-based access control language, to define protection policies. Our approach scales well in the number of public key operations required for web clients and does not reveal proprietary details of the logical enterprise network (because of the application of proxy re-encryption). We evaluate F3ildCrypt and show an additional cost of 40 to 150 ms when making sensitive transactions from the web browser, and a processing rate of 100 to 140 XML fields/second on the server. We believe such costs to be a reasonable tradeoff for increased sensitive-data confidentiality.
