Secure Bitcoin WalletGuler, Sevil January 2015 (has links)
Virtual currencies and mobile banking are technology advancements that are receiving increased attention in the global community because of their accessibility, convenience and speed. However, this popularity comes with growing security concerns, like increasing frequency of identity theft, leading to bigger problems which put user anonymity at risk. One possible solution for these problems is using cryptography to enhance security of Bitcoin or other decentralised digital currency systems and to decrease frequency of attacks on either communication channels or system storage. This report outlines various methods and solutions targeting these issues and aims to understand their effectiveness. It also describes Secure Bitcoin Wallet, standard Bitcoin transactions client, enhanced with various security features and services.

Understanding Adoption of Mobile Wallets : On Aged PopulationKoosha, Amirmohammad January 2018 (has links)
A mobile wallet is a mobile application that is intended to replace leather wallets. With high mobile and Internet penetration and increased life expectancy in developed economies, adoption of mobile wallets by the older population is becoming more important due to new trends. Therefore, this thesis aims to understand and increase adoption of mobile wallets in developed economies by the citizens between the ages of 50 to 75. Based on the mobile payment technology acceptance model (MPTAM) and an extensive literature review, a simplified model is suggested. Three sub-questions (on 1 - social influence, 2 - perceived security, trust and risks, and 3 – perceived ease of use) are proposed for further study, which has been suggested in the literature to have more importance for the targeted demography. An exploratory qualitative study based on in-depth semi-structured interviews was conducted. The findings show that social influence can have direct or indirect effects. Moreover, several factors were identified that seems to have impacts on the degree to which a content can influence people. In addition, perceived trust, security, and risks seem to be the most important impediment for the adoption of mobile wallets, especially for risk-averse people. Furthermore, perceived ease of use can improve the values that mobile wallets may provide. Perceived ease of use is more important for the targeted age group since some of the potential users in this age group has reduced learning and physical abilities. Finally, many implications of the findings and methods to improve the adoption of mobile wallets for the selected demography, i.e. restriction and customization, use of familiar design, use of strong brands, etc. are suggested.

使用圖碼技術於行動商務平台 / Apply Picture Code to Commerce Application何駿逸, Ho, Chun Yi Unknown Date (has links)
從過去的公元2000年所強調網路Dot Com時代來臨，資訊商務發展一路從電子錢包、電子商務、B2B、B2C、第三方支付、C2C、O2O..到近期的「行動支付」發展的角度上來看，因為網路的發達，無線網路覆蓋面積的增大，網路速度也不斷的提升，智慧型手機及行動裝置使用廣泛，讓整體消費市場由過去所重視的企業消費市場已大幅轉向重視個人的消費市場。
短短的這二、三年，因智慧型手機使用的普及，各種APP應用程式蓬勃發展，已徹底改變了人們的生活習慣，當人們想要獲取與傳遞資訊時，只要動動手指頭，馬上就可達成；相對的，人們對於智慧型手機行動裝置也越來越依賴。面對這一新的「動動手指頭的時代」發展與趨勢，加上個人消費者的使用與消費習慣改變，造就了消費市場巨幅的變化；企業更為爭取個人消費者的市場，作為企業競爭力之指標。從企業為爭取個人消費者的市場之發展趨勢來看，O2O （Online to Offline）更成為現代重要的營銷模式。
本研究的貢獻希望在於以便利商店繳交信用卡帳款為例得到之啟發，打造一個行動商務平台，藉由現代圖碼（Picture Code），即利用目前所常見使用的條碼，如：堆疊式二維條碼以及矩陣式二維條碼，結合現行還在開發之新技術，組合出更新，圖形更複雜且資料儲存量更大之圖碼當作介質，透過網路之連結，以現代資訊商務發展活動的應用模式為基礎，套用本研究之應用模型，作為對於個人使用者的身分驗證，以及個人消費者於現代資訊商務發展活動之「電子錢包」及「電子商務」、「第三方支付」乃至「C2C」在使用信用卡的應用上，透過使用智慧型手機或行動裝置，作為現代另一新的「行動支付」方法。同時，在完成商務交易活動後，又能結合O2O營銷模式，為使用或消費者個人帶來共多利益，也為商家創造出更多商機。 / From "Dot Com" network generation coming in 2000, the IT Business Development Activities from "Electronic Wallet", "e-commerce", "B2B", "B2C", "Third-party payment," "C2C", "O2O" to the recent "Mobile Payment" development, because the network developed, wireless network coverage area increases, network speed has also been improved, smart phones and mobile devices are popular, overall business market is focus on the individual consumer market now.
In this three years, smart phones use a variety of APP applications, it really has completely changed people's habits. When people want to capture and transmit some information, it just need to “move your fingers” as soon as you can reach. Also, people become increasingly dependent on smart phones and mobile devices. Face with this new "move your fingers time” developments trends and consumers’ consumption habits change, enterprise all want to increase the individual consumers’ market share and also as a business Indicators competitiveness. O2O （Online to Offline, Offline to Online） business model is more and more important to enterprise in the future.
This thesis investigates from a case study on credit card payment for bill in the convenience store to get an idea. Hope build up a mobile commerce platform and use the modern “Picture Code” that the current use of bar codes, such as Stacked 2D bar codes and two-dimensional matrix bar code and combined with the existing new technology still in development. The combination of updates, graphics and more complex and larger data storage capacity of the bar code to be the new “interface”.
Based on all application connect within Internet, we try to implement for all application according to development and innovation from this paper that to be a customer’s ID verification and “mobile payment” new model. Meanwhile, after transaction successfully, integrate the O2O business model to create more benefit for customer and more business opportunity for enterprise.

Rozbor a návrh aplikace pro digitální měnu Bitcoin / Analysis and implementation of application for digital currency BitcoinDRDÁK, František January 2015 (has links)
The thesis is focused on the topic of virtual cryptocurrency Bitcoin. The theoretical part is divided into several chapters. First of all, there is a chapter containing basic information about the currency's history, its development to the present, as well as principles of operation of this currency. Because it is a currency based on cryptographic principles next chapter summarizing cryptographic techniques, which is necessary to know for subsequent analysis of this currency. In other parts is elaborated a detailed analysis of the principles of Bitcoin. The main point of this analysis is a system of transactions, decentralized history, then joining the transactions into blocks and in the end creating blockchain. It also explains the principle of P2P networks. The practical part of this work focuses on the analysis and design of payment applications for mobile devices. There used open-source libraries such BitcoinJ. The application is developed in Java programming language with plugin for portable devices, which work under the operating system Android. For the purposes of analysis and design of graphical user interface is used UML diagrams. The specification of the UML diagrams was utilized by freely available graphics software and the result is also included in this work.

Blockchain Technology : a new domain for Cyber ForensicsRasool, Muhammad Ahsan, Muhammad Shafiq, Hafiz January 2018 (has links)
Traditional database with no prior security measures is becoming challenging in the era of data technology. Database storage on a central location with single point of failure and vulnerable to cyber attacks is getting exposed to big risk of being hacked with the evolution of powerful machines and modern hacking techniques. Since its commencement, the BlockChain technology has shown a promising performance for application buildup in diversed fields of life from cryptocurrency to smart contracts and decentralized applications. Although multiple studies on privacy, data confidentiality and security issues of BlockChain are performed but a systematic examination is still needs attention. In this thesis work we conduct a systematic study about the vulnerabilities of BlockChain system and review the security enhancement solutions that may point to a good future direction for further research into the area of BlockChain technology and its applications. Smart contracts are self-executable objects hosted on the 2nd generation blockchain like Ethereum, carry billions of SEK worth of cryptocoins and cannot be updated once deployed. Smart contracts are generally considered secure objects but the systematic analysis of technology and source code exposes a new class of vulnerabilities which are more likely an ethical aspect of programming than the software coding errors. Besides the literature review we empower our results with a static code analysis especially with the perspective of cyber forensics.

Exploratory study of market entry strategies for digital payment platformsMarcinkowska, Anna January 2018 (has links)
The digital payment industry has become one of the fastest evolving markets in the world, but in the wake of its rapid advancement, an ever increasing gap between academic theory and the actual reality of this market widens - and especially so when it comes to entry theory. It is widely acknowledged that the world is moving towards an ever more homogeneous economy, but despite the fact that payment preferences differ greatly from country to country - research on this subject continues to revolve mainly around localized efforts. But as historical inequalities between poor and rich societies continue to dissipate - learning from nations at the forefront of technological advancement increases the likelihood that the developed strategy becomes applicable to an increased number of countries. By selecting a nation most conducive to technological growth, the purpose of this report is to map the present dynamics in its digital payment industry using both recent and traditional market entry theory. However, studies geared towards globalized strategy formulation cannot be assumed as having guaranteed access to internal company-data at all times. So in order to facilitate such studies, the level of dependency on primary data required for conducting such research needs to be understood first, which is why the work in this report is constrained strictly to data of secondary nature. This, not only to further map the characteristics of this market, but also to see how open the market is to public inspection. Ultimately, the academic contribution becomes that of providing a road-map towards adapting currently available market entry theory to suit the rapidly evolving conditions of the digital payment industry from a global perspective and, when failing to do so, the aim is to also explore avenues for further research towards this end goal.

Legal and regulatory aspects of mobile financial servicesPerlman, Leon Joseph 11 1900 (has links)
The thesis deals with the emergence of bank and non-bank entities that provide a range of unique
transaction-based payment services broadly called Mobile Financial Services (MFS) to unbanked,
underserved and underbanked persons via mobile phones.
Models of MFS from Mobile Network Operators (MNOs), banks, combinations of MNOs and banks, and
independent Mobile Financial Services Providers are covered. Provision by non-banks of ‘bank-type’
services via mobile phones has been termed ‘transformational banking’ versus the ‘additive banking’
services from banks. All involve the concept of ‘branchless banking’ whereby ‘cash-in/cash out’ services
are provided through ‘agents.’
Funds for MFS payments may available through a Stored Value Product (SVP), particularly through a
Stored Value Account SVP variant offered by MNOs where value is stored as a redeemable fiat- or mobile
‘airtime’-based Store of Value.
The competitive, legal, technical and regulatory nature of non-bank versus bank MFS models is discussed,
in particular the impact of banking, payments, money laundering, telecommunications, e-commerce and
consumer protection laws. Whether funding mechanisms for SVPs may amount to deposit-taking such that
entities could be engaged in the ‘business of banking’ is discussed. The continued use of ‘deposit’ as the
traditional trigger for the ‘business of banking’ is investigated, alongside whether transaction and paymentcentric
MFS rises to the ‘business of banking.’
An extensive evaluation of ‘money’ based on the Orthodox and Claim School economic theories is
undertaken in relation to SVPs used in MFS, their legal associations and import, and whether they may be
deemed ‘money’ in law.
Consumer protection for MFS and payments generally through current statute, contract, and payment law
and common law condictiones are found to be wanting. Possible regulatory arbitrage in relation to MFS in
South African law is discussed.
The legal and regulatory regimes in the European Union, Kenya and the United States of America are
compared with South Africa. The need for a coordinated payments-specific law that has consumer
protections, enables proportional risk-based licensing of new non-bank providers of MFS, and allows for a
regulator for retail payments is recommended. The use of trust companies and trust accounts is
recommended for protection of user funds.
