OAuth 2.0 and OpenID Connect are widely used authorization frameworks in the development of web applications. However, there are privacy concerns when using these frameworks because an authentication server can easily identify the URI of a website being accessed by a client. In this study, we proposed and implemented an authorization scheme that allows a client to conceal a URI from an authentication...
This study adopted the methods of Market Approach and Income Approach to assess enterprise value of two samples in auto-lamp industry. Financial data from 2008 to 2013 was utilized. The evaluation based date was 31 December 2013. Sensitivity Analysis Method was also used to comprehend the effect of each value driver to the promotion of enterprise value. The findings of this study were as follows:...
The purpose of this study is two folds, one is to investigate differences of human resources and operating performance between two different competitive strategies (positive strategy and conservative strategy) adopted by Taiwan public accounting firms, and the other is to examine effects of human resources on operating performance under the two different competitive strategies. Empirical data is collected...
A sensor network is one popular candidate for the fundamental backbone of IoT (Internet of Things). Among the key technologies involved in sensor networks, fault detection techniques are indispensable for maintaining the availability of sensor applications. Chen et. al. (2006) presented a distributed fault detection (DFD) scheme to identify hard faults, such as power failures, crash faults, etc.,...
The exponential increase of data consumption in mobile networks is putting a lot of strain in the core network part, resulting in more signaling overhead. The need for a flexible and scalable new core network is eminent. In this paper, we propose to leverage the concept of Software-Defined Networking into the LTE core network to produce a flat and efficient new architecture for mobile networks. The...
This paper aims at balancing the load of OFDMA small cell networks. Different with the existing works that define the load as the number of service user equipments or the occupied amount of resources, we model the load as the service ability of small cells. The system load balancing problem that adopts the max-min fairness measure is formulated as a lexicographical minimization problem whose solution...
Wireless Delay Tolerant Networks (DTNs) are designed for intermittently connected wireless nodes to communicate with each other. In a DTN, messages are copied, stored and forwarded to other nodes when connection is established between nodes. Various routing protocols are designed to improve message delivery probability in networks but a very few of them consider energy constraint of nodes. In this...
Vehicular Ad hoc Network (VANET), a subclass of mobile ad hoc networks (MANETs), is a promising approach for the intelligent transportation system (ITS). One of the challenges of VANET is unstable channel with high mobility, and a communication interruption due to a dead end. In order to improve the packet delivery rate and suppress the communication traffic, SRS method was proposed. In SRS, a route...
Developing an energy efficient routing protocol for underwater wireless sensor networks (UWSNs) is a challenging task due to long propagation delay, low bandwidth, high error probability, and most importantly limited energy. Unlike ter-restrial sensor networks, UWSN environment is harsh. Nodes are provided with limited energy. The replacement or charging of batteries is not an easy task. By minimizing...
As the automobile industry has recently adopted information technologies, the latter are being used to replace mechanical systems with electronically-controlled systems. Moreover, automobiles are evolving into smart cars or connected cars as they are connected to various IT devices and networks such as VANET (Vehicular Ad hoc NETwork). Although there were no concerns about the hacking of automobiles...
Anomaly detection is playing an increasingly important role in network security, and the ability to detect and process anomalies for big data in real-time is a difficult task. In this conditions, this paper presents a model which combine cloud computing with machine learning. Hadoop is a widely used open source cloud computing framework to big data. The traffic data stored in HDFS and processed by...
This study aimed to assess the enterprise value of tourism industry. Data of financial statement from 2009 to 2013 was analyzed with the base date on 31 December, 2013. Sensitivity Analysis Method was conducted to convey the effect of each value driver on the promotion of enterprise value. This study found that the fundamental value of Lion Travel agent was NT$ 71.25 while the stock price at the evaluated...
We have been studying the survivals and declines of old-established companies. Particularly, we have revealed that many of time-honored companies have increased their sales by online shop business. However, we think that there are some issues. Old-established companies may have different ways of implementing e-business depending on types and the scales of business. There may be differences between...
This paper examines how firms bundle infrastructure capability and innovation orientation to enhance the service innovation with IT support (SIIT) and its impact on firm's performance outcomes of market performance and financial performance. The result of data gathered from 127 hotel service firms in Vietnam suggest that the impact of SIIT on firm outcomes begins with infrastructure capabilities and...
The stocks of many family firms trading in Taiwan Stock Exchange are holding by the family members to control the company. This study was to investigate the SEO behavior of the family firms from the viewpoint of agency theory.
The purpose of the present study was to examine the relationship between workplace friendship and social loafing effect among employees in Certified Public Accounting (CPA) firms. Previous studies showed that workplace friendship has both positive and negative effects, meaning that there is an inconsistent relationship between workplace friendship and social loafing. The present study investigated...
In response to the open-door economic policy of China, companies in Taiwan have gradually relocated their production lines to China in order to decrease production costs and meet major market needs. Moreover, previous studies have examined whether businesses can continually earn excess profits by researching and developing new technology or products using their strong human resources. Therefore, the...
This study explores the value implications of integrating information technology with service innovation and its antecedents. Specifically, this study examines how a firm's e-service capability and complementary co-operation capability with partners are bundled to form e-service innovation that either maintain or gain a competitive advantage. The results of data gathered from 119 financial service...
In recent years, both of financial technologies and its services for mobile devices have been increased sharply. However, according to the case studies of mobile security, security threats have been increased too. Thus, for sustaining their services safe, security department of companies or bank institutes continuously research and develop to upgrade their service solutions. However, recent researches...
Previous researches show that investors are not completely rational. Overconfidence is one of the investors irrationalities that have drawn special attention from academics. This study adopts the method of [1] to investigate the relationship between the overconfidence and stock prices, risks and business cycle in the Taiwan stock market.
