Essay On Blockchain

The cyber industry continues to innovate and offer new ways to help organizations stay secure and compliant. Over the past few months I've observed analyst, media and pundit coverage of three new cyber product categories - software defined segmentation, threat intelligence gateways and automated breach simulation. All three offer many new ways to increase the effectiveness and efficiency of your security programs. I will discuss each briefly and reference relevant Gula Tech Adventures portfolio companies in these new categories.

Bitcoin is an independent online system that uses features of both cash and online payment methods. Similar to the use of cash, Bitcoins allow the individuals to be anonymous with their transactions. The transaction is cryptographically signed to transfer the amount from one individual to another. At the same time these transactions are irreversible. This is similar to the no charge back risk that is found with credit cards. All Bitcoin transactions require a “third-party mediation: a global peer-to-peer network of participants validates and certifies all transactions” (Meiklejohn, et al., 2016). This decentralization entails each transaction of the entire system to be stored by each individual who uses Bitcoins. In 2012 this amounted to over three gigabits of compressed data (Meiklejohn, et al., 2016).

The message of its own is send by the attacker on the other end. This is done by avoiding to be noticed by the network. there are solutions provided to these type of problems. The solutions have prevented the attacks to a greater extent and have helped in maintaining the efficiency of the networks [6].

Blockchain technology innovation is proliferating in the hedge fund industry. Blockchain technology plays a primary role in front office and investment functions, in the securing of crypto assets, but also in private investment fund managers’ attempts to satisfy the growth expectations of clients. Although the use of blockchain technology in private investment fund strategies is still in its infancy, as it evolves and accelerates, the associated innovation benefits promise lasting change for the industry.

Hawala is a money transferring system that’s used in places such as the Middle East, North Africa, South Asia, and the idea is that a group of money brokers (Hawala dealers) rely solely on the honor system to transfer large amounts of money between two places, or people, without raising any red flags when it comes to law enforcement. As you can imagine, criminals have been able to take advantage of this system to escape traditional banking methods. Hawala is a method of transferring money without any actual movement of money to an intended destination. Hawala is subject to little or no paper and electronic trail because the system is solely based on the trust and honor of another human being and there is no traceable money from the

The history of electronic fund transfer and electronic banking are to a large extent ,closely interrelated with that of the automated banking systems and also the growth of the consumer financial service market now widely offered by banks.

The Silk Road began during the Han Dynasty around 202 B.C.E.-221 C.E., and lasted until around 1453 C.E., when the Ottoman Empire cut trade ties with the west. The Silk Road was a system of trade routes that connected empires across the Asia to the Mediterranean world, parts of Africa, and Europe. This extensive trade network received its name from the lucrative silk that came from China. Horses, ivory, grapes, metals, slaves, spices, textiles, wine, and other various items were traded through this network all over the ancient world, but the Silk Road traded more than material goods. Many ideas and technologies were shared among the empires connected by the Silk Road. Buddhist monks traveled along the road to India, sharing their beliefs with the Indian people. China shared gunpowder, paper-making, and printing with other civilizations. Astronomy, linguistics, and mathematics were also shared concepts that spread due to the Silk Road. The Silk Road is so historically significant due to its influence on commerce within the ancient world and its advancements of innovative ideas and technologies that were spread throughout all ancient civilizations.

Often there has been a need to protect information from 'prying eyes'. In the electronic age, information that could otherwise benefit or educate a group or individual can also be used against such groups or individuals. Industrial espionage among highly competitive businesses often requires that extensive security measures be put into place. And, those who wish to exercise their personal freedom, outside of the oppressive nature of governments, may also wish to encrypt certain information to avoid suffering the penalties of going against the wishes of those who attempt to control.

Present day transactions are considered to be "un-trusted" in terms of security, i.e. they are relatively easy to be hacked. We also have to consider the transfer of large amount of data through the network will give errors while transferring. Only single level of security is present in the existing systems [10]. Now days, hacking activities are growing day by day and hackers can easily hack important information and security is not sufficient to stop it. Though security status increased at a higher level but the major drawback of new status of security is cost, and became so costly. Hence we need better solutions which have good security level with lower cost.

Information systems can be classified into four types. These type are highly recognizable within an organization, mainly for its effectiveness in terms of interpreting information. Information systems are both manage by people such as analysts and automated systems such as databases servers, in a way they complement each other. Its aim is to assist and maintain the management, operation, and decision making of the organization’s day to day procedures.

To start off primarily, Bitcoin is a digital currency as opposed to physical currency that we’re accustomed to and use in our daily life. Straight off their site, Bitcoin is described as a pseudo-anonymous, P2P technology operating with no central authority or banks, it’s open-source, public, owned by no one and open for everybody to take part; but what does that all mean? “Bitcoin is the leader in a new generation of emerging currencies known as “cryptocurrencies” which aim to, among other things, facilitate the movement of money electronically while still maintaining a sense of privacy,” (Hobson)

Blockchain Technology supports a distributed ledger system and maintains a growing list of records that are confirmed by the participating people. In blockchain framework, each transaction is recorded in public ledger and stores the information of the transaction. In Current scenario, all the currency transactions between persons or entities are centralized and controlled by some other organizations (Interoperability team). Transferring money will needs bank and merchants who process the payments and they charge fee for each transaction. This is the common phenomenon in every domain and this complexity is simplified by Blockchain technology by creating decentralized environment where no interoperability team is required to control the

Two set of text images and one true sample image is taken for cryptography. In this proposed work these three images are encrypted into various shares through MATLAB, so that after compiling specific number of share the original image is visible. After encryption the performance analysis is done with the help of PSNR and MSE values.

It has the feature of ring signature that provides that provides you the safe and secure transaction. Transactions of Monero are always private.

Multi- User operating system (MUOS) is an operating system where one or more user can work at a same time without any disturbance by the other user. In this operating system users can do multiple task at a same time and browse more than one browser minimizing another. Some example of multi- user operating system are windows 8,
