In the emerging competitive and technological driven banking era, banks have to strive hard for retaining and enlarging their customer base. Electronic customer relationship management (E-CRM) is the combination of traditional CRM with the e-business applications marketplace. An E-CRM system provides financial institutions with the opportunity to establish individual and need oriented customer ...

Capital allocation for credit portfolios has two meanings. First, at portfolio level it means to determine capital as a buffer against an unexpected negative cash-flow resulting from credit losses. In this case, the allocation method can be specified by means of a risk measure. Its result is called economic capital of the portfolio. Second, at sub-portfolio or transaction level, capital allocat...

We hypothesize that the degree of public attention influences the price level of stocks in a systematic way. We employ a simple discounted cash flow model with adverse selection and fixed transaction costs that determine an endogenous bid-ask-spread. In the model, rational and risk neutral investors incorporate future trading conditions into their price setting behavior. These trading condition...

We propose a generic framework for the development of an off-line peer-to-peer electronic payment system with fixed-value electronic coins. The proposed scheme simulates the issuance, circulation and characteristics of conventional cash and satisfies important security, privacy and usability requirements, offering a comparative advantage over other existing solutions. We exploit the strong secu...

Data mining has been increasing as one of the chief key features of many security initiatives. Often, used as a means for detection of fraud, assessing risk as well. Data mining involves the use of data analysis tools to discover unknown, valid patterns as well as relationships in large data sets. Decades have seen a massive growth in the use of credit cards as a transactional medium. Data mini...

A 24-hour exchange market was created on the Web to trade political futures contracts using fictitious money. In this online market, a political futures contract is a futures contract which matures on the election day with a liquidation price determined by the percentage of votes a candidate receives on the election day. Continuous double auctions were implemented as the system for order storag...

The basic objective of this work is to construct an efficient and secure mechanism for mobile commerce applying the concept of financial cryptography and secure multi-party computation. The mechanism (MCM) is defined by various types of elements: a group of agents or players, actions, a finite set of inputs of each agent, a finite set of outcomes as defined by output function, a set of objectiv...

Bitcoin is a peer-to-peer electronic cash system largely used for online financial transactions. It gained popularity due to its anonymity, privacy, and comparatively low transaction cost. Its wallet heavily relies on Elliptic Curve Digital Signature Algorithm (ECDSA). Weaknesses in such algorithms can significantly affect the safety security of bitcoin wallets. In this paper, secure key manage...

We extend the Barth, Cram, and Nelson (2001) model with disaggregated accruals by investigating whether cash flow components (core and non-core cash flows) improve cash flow predictability. BCN investigate the role of accrual components in predicting future cash flows while this study extends their study by investigating the role of cash flow components. We propose a cash flow prediction model ...
