EigenTrust
EigenTrust algorithm is a reputation management algorithm for peer-to-peer networks, developed by Sep Kamvar, Mario Schlosser, and Hector Garcia-Molina. The algorithm provides each peer in the network a unique global trust value based on the peer's history of uploads and thus aims to reduce the number of inauthentic files in a P2P network. It has been cited by approximately 3853 other articles according to Google Scholar. Overview Peer-to-peer systems available today (like Gnutella) are open, often anonymous and lack accountability. Hence a user with malicious intent can introduce into the peer-to-peer network resources that may be inauthentic, corrupted or malicious ( Malware). This reflects poorly on the credibility of current peer-to-peer systems. A research team from Stanford provides a reputation management system, where each peer in the system has a unique global trust value based on the peer's history of uploads. Any peer requesting resources will be able to access the tru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reputation Management
Reputation management, originally a public relations term, refers to the influencing, controlling, enhancing, or concealing of an individual's or group's reputation. The growth of the internet and social media led to growth of reputation management companies, with search results as a core part of a client's reputation. Online reputation management, sometimes abbreviated as ORM, focuses on the management of product and service search engine results. Ethical grey areas include mug shot removal sites, astroturfing customer review sites, censoring complaints, and using search engine optimization tactics to influence results. In other cases, the ethical lines are clear; some reputation management companies are closely connected to websites that publish unverified and libelous statements about people. Such unethical companies charge thousands of dollars to remove these posts – temporarily – from their websites. This field of public relations has developed extensively, with ...

Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific Computational problem, problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can perform automated deductions (referred to as automated reasoning) and use mathematical and logical tests to divert the code execution through various routes (referred to as automated decision-making). Using human characteristics as descriptors of machines in metaphorical ways was already practiced by Alan Turing with terms such as "memory", "search" and "stimulus". In contrast, a Heuristic (computer science), heuristic is an approach to problem solving that may not be fully specified or may not guarantee correct or optimal results, especially in problem domains where there is no well-defined correct or optimal result. As an effective method, an algorithm ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peer-to-peer
Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the network. They are said to form a peer-to-peer network of nodes. Peers make a portion of their resources, such as processing power, disk storage or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts. Peers are both suppliers and consumers of resources, in contrast to the traditional client–server model in which the consumption and supply of resources are divided. While P2P systems had previously been used in many application domains, the architecture was popularized by the file sharing system Napster, originally released in 1999. The concept has inspired new structures and philosophies in many areas of human interaction. In such social contexts, peer-to-peer as a meme refers to the egalitarian so ...

Héctor García Molina
Hector () is an English, French, Scottish, and Spanish given name. The name is derived from the name of Hektor, a legendary Trojan champion who was killed by the Greek Achilles. The name ''Hektor'' is probably derived from the Greek ''ékhein'', meaning "to have", "to hold", "to check", "restrain". In Scotland, the name ''Hector'' is sometimes an anglicised form of the Scottish Gaelic ''Eachann'', and the pet form ''Heckie'' is sometimes used. The name of Sir Ector, the foster father of King Arthur, is also a variant of the same. Etymology In Greek, is a derivative of the verb ἔχειν ''ékhein'', archaic form * grc, ἕχειν, hékhein, label=none ('to have' or 'to hold'), from Proto-Indo-European *'' seɡ́ʰ-'' ('to hold'). , or as found in Aeolic poetry, is also an epithet of Zeus in his capacity as 'he who holds verything together. Hector's name could thus be taken to mean 'holding fast'. Cognates *Irish: ''Eachtar'' *Italian: ''Ettore'' *Portuguese: ''Heitor'' *G ...
