High-dimensional classification and attribute-based forecasting
… with higher prediction accuracy than the method based on the assumption of independent observations. The second part of this thesis develops a new forecasting approach for large-scale datasets associated with a large number of predictor categories and with predictor structures. The new approach, …

A Lightweight Attribute-Based Access Control System for IoT.
The evolution of the Internet of things (IoT) has made a significant impact on our daily and professional life. Home and office automation are now even easier with the implementation of IoT. Multiple sensors are connected to monitor the production line, or to control an unmanned environment is now …

Towards Practical and Secure Decentralized Attribute -Based Authorization Systems
We first show that existing ABAC theory does not properly account for the asynchronous nature of open systems, which allows attackers to subvert these systems by forcing decisions to be made using inconsistent system states. To address this, we develop provably-secure and lightweight consistency …

Interactively Guiding Semi-Supervised Clustering via Attribute-based Explanations
… In this work, we propose to use image attributes as a modality for the user to provide more informative cues. In particular, the clustering algorithm iteratively and actively queries a user with an image pair. Instead of the user simply providing a must-link/cannot-link constraint for …

Efficient Ciphertext-policy Attribute Based Encryption for Cloud-Based Access Control
… such access control using Ciphertext-policy attribute based encryption (CP-ABE) that can enforce data owners’ access policies to achieve such cryptographic access control and tackle the majority of those concerns. However, some challenges are still outstanding due to the complexity of …

A case study on an attribute-based design method selection framework
… the effectiveness of using the concept of attributes or properties to identify, compare, and select methods for the design of aerospace systems. Growing product development cost trends for these complex systems have been alarming to the aerospace industry. To curb rising development costs …

Context-Aware Attribute-Based Techniques for Data Security and Access Control in Mobile Cloud Environment
… smart mobile devices to host various Cloud-based services such as Google apps, Instagram, and Facebook. Recent developments in smart devices‟ hardware and software provide seamless interaction between the users and devices. As a result, in contrast to the traditional user, the mobile user in …

A Dynamic Attribute-Based Load Shedding and Data Recovery Scheme for Data Stream Management Systems
… a new approach for shedding the less informative attribute data from a data stream with a fixed schema to maintain a data rate lesser than the network channels capacity. A scheme for shedding attributes, instead of tuples, becomes imperative in stream data where the data for one of the attributes …

Farmland Conservation Easement Valuation Using an Attribute-based Choice Survey: Comparing Preferences within the United States, Georgia, Ohio and Maine
… existence of farmland. Through the data from an attribute-based choice survey (conducted in four geographic areas) the willingness-to-pay (WTP) of the public to preserve farmland that exhibited certain attributes, was estimated. The attributes included different use (grain, hay, vegetable, …

CITE Suitability : an exploration of product evaluation methodologies for developing world technologies
… implemented, and compared. The first is an attribute-based product evaluation, in the style of Consumer Reports, in which all products under evaluation are subjected to a standardized set of laboratory tests designed to differentiate among products in key performance areas. The second is a …

Frontiers in Lattice Cryptography and Program Obfuscation
… contribution is the construction of a deniable attribute-based encryption scheme from lattices. A deniable encryption scheme is secure against not only eavesdropping attacks as required by semantic security, but also stronger coercion attacks performed after the fact. An attribute-based …

Mezőgazdasági táblák talajheterogenitás vizsgálata Sentinel 2 NDVI adatok felhasználásával
… képeket. A térinformatikai adatbázis adataiból „Attribute based clustering” modulját felhasználva 40x futtatott k-közép (k-mean) eljárással három csoportot (klasztert) képeztünk az adatokból. Az NDVI értékek középérték összehasonlítását legkisebb szignifikáns különbség (LSD) módszerével végeztem, …

Face Verification with Veridical and Caricatured Images using Prominent Attributes
… networks has led to a shift in focus away from attribute-based representations, further complicating the matching process. In this thesis, we introduce a classification protocol for prominent facial feature recognition along with a verification protocol for matching celebrity veridical images to …

The design and implementation of a relational interface for the multi-lingual database system
… model followed by the specification of a model -based data language. Thus, the database system is restricted to a single data model and a specific data language. An alternative to this traditional approach to database—system development is the multi-lingual database system (MLDS) . This …

Arcana: Private tweets on a public microblog platform
… system, which utilizes CP-ABE (Ciphertext Policy Attribute based encryption), allowing the user to select followers based on predefined attributes. Through simple installation and pre-setting, the user can encrypt and decrypt tweets conveniently and can avoid the fear of information leakage.

Individual and Holistic Information Processing
… process information individually, or with an attribute based approach. A preliminary study tested the averaging and additive effects of information processing and served as the foundation for two subsequent explorations. The first examined cultural differences in information processing through …

Cryptographically enforced access control for user data in untrusted clouds
… to support rich, legacy web applications. Using attribute-based encryption, Sieve allows users to define intuitive, understandable access policies that are cryptographically enforceable. Using key homomorphism, Sieve can re-encrypt user data on storage providers in situ, revoking decryption keys …
