Local Differential Privacy
Local differential privacy (LDP) is a model of differential privacy with the added requirement that if an adversary has access to the personal responses of an individual in the database, that adversary will still be unable to learn much of the user's personal data. This is contrasted with global differential privacy, a model of differential privacy that incorporates a central aggregator with access to the raw data. Local differential privacy (LDP) is an approach to mitigate the concern of data fusion and analysis techniques used to expose individuals to attacks and disclosures. LDP is a well-known privacy model for distributed architectures that aims to provide privacy guarantees for each user while collecting and analyzing data, protecting from privacy leaks for the client and server. LDP has been widely adopted to alleviate contemporary privacy concerns in the era of big data. History The randomized response survey technique proposed by Stanley L. Warner in 1965 is frequen ...

Differential Privacy
Differential privacy (DP) is a mathematically rigorous framework for releasing statistical information about datasets while protecting the privacy of individual data subjects. It enables a data holder to share aggregate patterns of the group while limiting information that is leaked about specific individuals. This is done by injecting carefully calibrated noise into statistical computations such that the utility of the statistic is preserved while provably limiting what can be inferred about any individual in the dataset. Another way to describe differential privacy is as a constraint on the algorithms used to publish aggregate information about a statistical database which limits the disclosure of private information of records in the database. For example, differentially private algorithms are used by some government agencies to publish demographic information or other statistical aggregates while ensuring confidentiality of survey responses, and by companies to collect informa ...

Geopositioning
Geopositioning is the process of determining or estimating the geographic position of an object or a person. Geopositioning yields a set of geographic coordinates (such as latitude and longitude) in a given map datum. Geographic positions may also be expressed indirectly, as a distance in linear referencing or as a bearing and range from a known landmark. In turn, positions can determine a meaningful location, such as a street address. Geoposition is sometimes referred to as ''geolocation'', and the process of geopositioning may also be described as ''geo-localization''. Specific instances include: * animal geotracking, the process of inferring the location of animals over time; * positioning system, the mechanisms for the determination of geographic positions in general; * internet geolocation, geolocating a device connected to the internet; * and mobile phone tracking. Geofencing ''Geofencing'' involves creating a virtual geographic boundary (a geofence), enabling software ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traffic Management
Traffic management is a key branch within logistics. It concerns the planning, control and purchasing of transport services needed to physically move vehicles (for example aircraft, road vehicles, rolling stock and watercraft) and freight. Traffic management is implemented by people working with different job titles in different branches: * Within freight and cargo logistics: traffic manager, assessment of hazardous and awkward materials, carrier choice and fees, demurrage, documentation, expediting, freight consolidation, insurance, reconsignment and tracking * Within air traffic management: air traffic controller * Within rail traffic management: rail traffic controller, train dispatcher or signalman * Within road traffic management: traffic controller See also * Air traffic control Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and ...

Internet Of Vehicles
Internet of vehicles (IoV) is a network of vehicles equipped with sensors, software, and the technologies that mediate between these with the aim of connecting & exchanging data over the Internet according to agreed standards. IoV evolved from Vehicular Ad Hoc Networks ("VANET", a category of mobile ad hoc network used for communication between vehicles and roadside systems), and is expected to ultimately evolve into an "Internet of autonomous vehicles". It is expected that IoV will be one of the enablers for an autonomous, connected, electric, and shared (ACES) Future Mobility. Road vehicles as a product category depend upon numerous technology categories from real-time analytics to commodity sensors and embedded systems. For these to operate in symphony the IoV ecosystem is dependent upon modern infrastructure and architectures that distribute computational burden across multiple processing units in a network. In the consumer market, IoV technology is most typically referenced in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloud Server
A virtual private server (VPS) or virtual dedicated server (VDS) is a virtual machine sold as a service by an Internet hosting company. A virtual private server runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes, it is functionally equivalent to a dedicated physical server and, being software-defined, can be created and configured more easily. A virtual server costs less than an equivalent physical server. However, as virtual servers share the underlying physical hardware with other VPS, performance may be lower depending on the workload of any other executing virtual machines. Virtualization The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Aggregation
Data aggregation is the compiling of information from databases with intent to prepare combined datasets for data processing. Description The United States Geological Survey explains that, “when data are well documented, you know how and where to look for information and the results you return will be what you expect.” The source information for data aggregation may originate from public records and criminal databases. The information is packaged into aggregate reports and then sold to businesses, as well as to local, state, and government agencies. This information can also be useful for marketing purposes. In the United States, many data brokers' activities fall under the Fair Credit Reporting Act (FCRA) which regulates consumer reporting agencies. The agencies then gather and package personal information into consumer reports that are sold to creditors, employers, insurer Insurance is a means of protection from financial loss in which, in exchange for a fee, a party ...

Outsourcing
Outsourcing is a business practice in which companies use external providers to carry out business processes that would otherwise be handled internally. Outsourcing sometimes involves transferring employees and assets from one firm to another. The term ''outsourcing'', which came from the phrase ''outside resourcing'', originated no later than 1981 at a time when industrial jobs in the United States were being moved overseas, contributing to the economic and cultural collapse of small, industrial towns. In some contexts, the term smartsourcing is also used. The concept, which ''The Economist'' says has "made its presence felt since the time of the Second World War", often involves the contracting out of a business process (e.g., payroll processing, claims processing), operational, and/or non-core functions, such as manufacturing, facility management, call center/call center support. The practice of handing over control of public services to private enterprises ( privatiz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Health Industry
The healthcare industry (also called the medical industry or health economy) is an aggregation and integration of sectors within the economic system that provides goods and services to treat patients with curative, preventive, rehabilitative, and palliative care. It encompasses the creation and commercialization of products and services conducive to the preservation and restoration of well-being. The contemporary healthcare sector comprises three fundamental facets, namely services, products, and finance. It can be further subdivided into numerous sectors and categories and relies on interdisciplinary teams of highly skilled professionals and paraprofessionals to address the healthcare requirements of both individuals and communities.HEALTH PROFESSIONS [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federated Learning
Federated learning (also known as collaborative learning) is a machine learning technique in a setting where multiple entities (often called clients) collaboratively train a model while keeping their data Decentralized computing, decentralized, rather than centrally stored. A defining characteristic of federated learning is data Homogeneity and heterogeneity (statistics), heterogeneity. Because client data is decentralized, data samples held by each client may not be Independent and identically distributed random variables, independently and identically distributed. Federated learning is generally concerned with and motivated by issues such as Information Privacy, data privacy, data minimization, and data access rights. Its applications involve a variety of research areas including Arms industry, defence, telecommunications, the Internet of things, and Pharmaceutical industry, pharmaceuticals.

Eigenface
An eigenface ( ) is the name given to a set of eigenvectors when used in the computer vision problem of human face recognition. The approach of using eigenfaces for recognition was developed by Sirovich and Kirby and used by Matthew Turk and Alex Pentland in face classification. The eigenvectors are derived from the covariance matrix of the probability distribution over the high-dimensional vector space of face images. The eigenfaces themselves form a basis set of all images used to construct the covariance matrix. This produces dimension reduction by allowing the smaller set of basis images to represent the original training images. Classification can be achieved by comparing how faces are represented by the basis set. History The eigenface approach began with a search for a low-dimensional representation of face images. Sirovich and Kirby showed that principal component analysis could be used on a collection of face images to form a set of basis features. These basis ima ...

Biometric
Biometrics are body measurements and calculations related to human characteristics and features. Biometric authentication (or realistic authentication) is used in computer science as a form of identification and access control. It is also used to identify individuals in groups that are under surveillance. Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals. Biometric identifiers are often categorized as physiological characteristics which are related to the shape of the body. Examples include, but are not limited to fingerprint, palm veins, face recognition, DNA, palm print, hand geometry, iris recognition, retina, odor/scent, voice, shape of ears and gait. Behavioral characteristics are related to the pattern of behavior of a person, including but not limited to mouse movement, typing rhythm, gait, signature, voice, and behavioral profiling.
