Observational Study On Algorithms On The Social Networks

• Even with open installment some type of Smart card is normal for kids, poor people and the individuals who would prefer not to uncover their credit and platinum cards to the framework.

If you have ever bought something over the internet and used a credit card you may not have thought how secure is my information? Is this vendor someone I can trust with my credit card number? Will they inform me if my information is lost or stolen by them? These questions and many more can be answered by the Payment Card Industry Data Security Standard (PCI DSS). The PCI DSS compliance requirements are strictly enforced by the payment card brands to all merchants who transmit, store, or process credit card information. The main goals or objectives of PCI DSS are: build and maintain a secure network that is PCI compliant; protect cardholder data; maintain a vulnerability management program; implement strong access control measures; regularly

2) Barriers with sub-ordinates: These are due to reasons like the unwillingness to communicate any negative information since there is a fear that it may reflect on their performance. Hence such information, which

Proposed algorithm consider three types of nodes every type have different initial energy level. normal nodes have E_0 energy. m advanced nodes have a times energy more than normal nodes with E_0 (1+a) energy level. m_0 super nodes have b times energy more than normal nodes with E_0 (1+b) energy level, where a and b are energy factors. As N is the number of total nodes in network, then for number of normal nodes, advanced nodes and super nodes N(1-m) , Nm〖(1-m〗_0) and Nmm_0 in the network, respectively.

\newline Although the qualities of this method were competitive compared to those of other state-of-the-art methods, its efficiency and effectiveness was overshadowed by its computational time and space constraints thereby, limiting its application. To address this issue, Raymond et al. \cite{Raymond} extended \cite{Kashima}, proposing a fast and scalable algorithm for link propagation. This proposed algorithm utilizes matrix factorization and approximation techniques (such as the Cholesky and eigen-decomposition) to reduce the computational time and space required in solving linear equations in the Link Propagation. The proposed methods are also effective in link prediction on dynamic

Social networks are growing day by day. For modular representation of Graph $G(V,E)$ first phase of the design issue is to modularize the network having border nodes\cite{newman2006modularity}. Boarder nodes

to the measured data. Doing so may allow for further understanding concerning the possible errors

When online commerce first emerged, many consumers were wary of supplying their credit cards and giving their personal information to online stores. This led to the development of websites such as Paypal, which restricts the access a retailer has to one’s credit card number (Einstein). The threat of fraud has always been a worry for online consumers, but consumers face the same threats when shopping in a brick and mortar store (Chadwick).

The major routes of fraud which is contrary for merchants who sale and ship products are the mail and the internet as they affect legitimate mail-order and Internet merchants. The card should be present (called CNP, card not present) so the merchant can trust the issuer (or someone purporting to be so) issuers present their information in any way they

Card information was stolen by hackers and sold to others. Result in customer loss their money.

In the End make sure that you play your part wisely in keeping your Card information Safe. You already know what I am talking about.

Given the lack of ability to inspect merchandise before purchase, consumers are at higher risk of fraud than face-to-face transactions. Merchants also risk fraudulent purchases using stolen credit cards or fraudulent repudiation of the online purchase. However, merchants face less risk from physical theft by using a warehouse instead of a retail storefront. Secure Sockets Layer (SSL) encryption has generally solved the problem of credit card numbers being intercepted in transit between the consumer and the merchant. However, one must still trust the merchant and employees not to use the credit card information subsequently for their own purchases, and not to pass the information to others. Also, hackers might break into a merchant's web site and steal names, addresses and credit card numbers, although the Payment Card

Network theory is becoming more and more used within football to help teams analyse and change their style of play. It consists of a collection of nodes, with edges joining them that are weighted depending on how frequent a path is used. In football, the nodes represent the players of a team, the edges will be the passes between them and the weight will be the amount of passes between them. We will

Gossip-based algorithm plays a major part for distributing simple and efficient information in large networks. One of the examples of gossip-based algorithm is rumor –spreading model. It is also called as rumor mongering. It is introduced by Daley & Kendall (D K model) in the context of duplicated databases. The rumor spreading algorithm is an example of epidemic process. It is mainly used to examine in the view of mathematics. The algorithm follows synchronous rounds. The main aim of rumor spreading is to spread a rumor to all nodes in a social network in small no of rounds. At the beginning of the round, the information is sent to initial node known as start node. Then the information is sent to all nodes. The node having information will not accept to receive the information again. While executing the algorithm the graph and degree of nodes must be constant. In case of dynamic networks, an evolving graph is introduced to study the behavior of graph and nodes.

Very high dimensionality of the data, this requires the ability to deal with sparse data spaces or a method of dimensionality reduction.
