Backward Private Searchable Symmetric Encryption with Improved Locality

Searchable symmetric encryption (SSE) enables clients to outsource their encrypted documents into a remote server and allows them to search the outsourced data efficiently without violating the privacy of the documents and search queries. Dynamic SSE schemes (DSSE) include performing update queries, where documents can be added or removed at the expense of leaking more information to the server. Two important privacy notions are addressed in DSSE schemes: forward and backward privacy. The first one prevents associating the newly added documents with previously issued search queries. While the second one ensures that the deleted documents cannot be linked with subsequent search queries. Backward has three formal types of leakage ordered from strong to weak security: Type-I, Type-II, and Type-III. In this paper, we propose a new DSSE scheme that achieves Type-II backward and forward privacy by generating fresh keys for each search query and preventing the server from learning the underlying operation (del or add) included in update query. Our scheme improves I/O performance and search cost. We implement our scheme and compare its efficiency against the most efficient backward privacy DSSE schemes in the literature of the same leakage: MITRA and MITRA*. Results show that our scheme outperforms the previous schemes in terms of efficiency in dynamic environments. In our experiments, the server takes 699ms to search and return (100,000) results.
STUDYING CONNECTIVITY BETWEEN TIME-SERIES USING AN INTERACTIVE APPLICATION

Connectivity is a complex concept whose meaning varies for each domain.In a broad sense, it is possible to divide the connectivity in two main groups: physical and statistical.The former represents whether there is a physical link connecting the elements, like the telephone line, while the latter indicates a relation between the dynamics of the elements, as the number of sales and the income of a company.In several scientific fields, including economics, physics and neuroscience, the statistical connectivity is computed based on the analysis of time-series.Several different methods can be applied on the data, using different features of the signals, like covariance and frequency, to estimate the connectivity, yielding different results and interpretations.The covariance indicates if two elements follow the same dynamics, i.e., if they increase or decrease at the same time.On the other hand, the frequency is related to the time required for the elements to change, which can be daily in the case of the tides, or milliseconds if referred to the computations in a microchip.A third factor is the directionality, with one element depending on the other, but not in the opposite case.This work proposes an interactive computer-based application to generate a three-node network and estimate its connectivity following different approaches.We describe how the application is structured, from the selection of the parameters to the interpretation of the output results, detailing the skills in connectivity that can be developed by the students.

Progressive Class-Based Expansion Learning for Image Classification

In this paper, we propose a novel image process scheme called class-based expansion learning for image classification, which aims at improving the supervision-stimulation frequency for the samples of the confusing classes. Class-based expansion learning takes a bottom-up growing strategy in a class-based expansion optimization fashion, which pays more attention to the quality of learning the fine-grained classification boundaries for the preferentially selected classes. Besides, we develop a class confusion criterion to select the confusing class preferentially for training. In this way, the classification boundaries of the confusing classes are frequently stimulated, resulting in a fine-grained form. Experimental results demonstrate the effectiveness of the proposed scheme on several benchmarks.

Gamification Analysis in Ui And Ux for Parking Spot Apps

Advances in personal computing and information technology have been updated and published online or via mobile devices. Consequently, we must consider interaction as a fundamental complement of representation in cartography and visualization. The user interface (UI) / UX (user experience) describes a series of concepts, guidelines and workflows to critically reflect on the design and use of an interactive, map- based or other product. This entry presents the basic concepts of UI / UX design that is important for cartography and visualization, focusing on issues related to visual design. First, a fundamental distinction is made between the use of an interface as a tool and the broader experience of an interaction, a distinction that separates UI design and UX design. The phases of the Norman interaction framework are not a different form of interaction structure. Finally, three dimensions of the user interface design are described: the fundamental interaction operators that form the basic blocks of the interfaces, the interface styles that these primitive operators implement and the recommendations for the visual design of an interface.
