Sharing copyrighted files without copyright holder's permission is illegal. But, a number of illegal file sharers using BitTorrent increase. However, it is difficult to find appropriate digital evidences and legal basis to punish them. And, there are no framework for digital investigation of illegal sharing using BitTorrent. Additionally, role of server in BitTorrent had been reduced than server in conventional P2P. So, It is difficult to apply investigation framework for illegal sharing using conventional P2P to investigation process of illegal sharing using BitTorrent. This paper proposes the methodology about punishing illegal sharer using BitTorrent by suggesting the digital investigation framework.

The advent of various smart devices like smart phones and tablets has triggered the changes in information systems of medical centers. Especially, diversifying devices of clients and the need for N-Screen services increase necessities for sharing effectively information in medical centers. However, developing and managing clients for each OS like iOS and Android cost high and make it hard to provide seamless service through multi devices. Also, in the aspect of security it is necessary to share information between clients and health information systems. In this paper, we develop a smart health information client based real-time health information sharing framework. The developed client is based on hybrid app, that enables to share information in real time between N devices through health information sharing framework and to adopted to developments of various clients.

Due to the wide growth and popularity of social network website, large numbers of users discover these social network sites are a place where they can be able to spend their leisure time sharing interests, sharing ideas freely, sharing personal experience, and also to search for new friends or partners. These websites give an opportunity for its users to socialize with new people and to keep in touch or reconnect with current or old friends and families across disperse continents, which traditionally replace the common traditional methods. These social network websites need accurate and careful investigations and findings on the usability issues for effective interactivity and more usability. However, little research might have previously invested on the usability of these social network websites. Therefore, we propose a new framework to study and test the usability of these social network sites. We namely call our framework "Interactivity". This framework will enable developers to assess the usability of the social network sites. It will provide an overview of the user's behavior while interacting in these social network websites. Performance of the framework will be performed using Camtasia software. This software will entirely capture the interactivity of users including the screen and the movements, which the screen and the motion of the user action will undergo to analysis at the end of our research.

The goal of this study is to see if there's a relationship between employees' ambidextrous behaviors and macro facilitators of organizational empowerment (such as control over workplace decisions, dynamic structural framework, and fluidity in information sharing) (exploration and exploitation). To acquire data, this study uses survey methods. A cross-sectional survey was done to collect information from academics at five large public sector universities in Pakistan's Balochistan province. Control over workplace decisions boosts academics' engagement in exploration and exploitation, while a dynamic structural framework merely increases their engagement in exploration, according to the findings based on data from 240 respondents (n = 240). The findings also show that information sharing flexibility has little effect on exploration and exploitation behaviors. In conclusion, the results of this study imply that organizational empowerment is critical for academics' ambidextrous behaviors to thrive. As a result, specific organizational facilitators of empowerment (such as control over workplace decisions and a dynamic structural framework) are advised in higher education institutions. This research is significant because it develops and tests a model that explains hitherto unexplored connections between macro facilitators of organizational empowerment and employees' ambidextrous behaviors. In addition, the research provides important insights for managerial practice and research.

The emerging of cloud data sharing can create great values, especially in multi-cloud environments. However, "data island" between different cloud service providers (CSPs) has drawn trust problem in data sharing, causing contradictions with the increasing sharing need of cloud data users. And how to ensure the data value for both data owner and data user before sharing, is another challenge limiting massive data sharing in the multi-cloud environments. To solve the problems above, we propose a Uniform Encoding and Parsing Framework (UEPF) with blockchain to support trustworthy and valuable data sharing. We design namespace-based unique identifier pair to support data description corresponding with data in multi-cloud, and build a blockchain-based data encoding protocol to manage the metadata with identifier pair in the blockchain ledger. To share data in multi-cloud, we build a data parsing protocol with smart contract to query and get the sharing cloud data efficiently. We also build identifier updating protocol to satisfy the dynamicity of data, and data check protocol to ensure the validity of data. Theoretical analysis and experiment results show that UEPF is pretty efficient.

Identity authentication sharing technology which allows many service providers to share the result of identity authentication of an identity provider provides several important advantages including high usability achieved by avoiding repeated registration of identity information to service providers and single sign-on, cost effectiveness of service providers achieved by outsourcing identity authentication services from identity providers, and privacy protection achieved by exposing identity information only to a limited number of controlled identity providers. However, in order for the identity authentication sharing technologies to be widely deployed in global Internet scale, the trustworthiness issue among the participating identity providers, service providers, and users should be resolved in advance. This paper firstly analyzes existing trust frameworks for identity authentication sharing. And then, based on the result of analysis, this paper proposes a dynamic and open trust framework for identity authentication sharing.

Several countries have built National Spatial Data Infrastructure (NSDI) for information sharing among various fields. One of the important factors of NSDI is framework data, which is the most commonly used geospatial data across various fields. Previous studies on the framework data suggest components based on frequency survey and case study. However, such research methods do not have objectivity in setting the components of the framework data. This research uses factor analysis with 104 medium-level layers from the most widely used National Base Map and 5 layers from the other sources including cadastre and aerial image. Each layer is scaled with usage level as four different patterns of 1) background data, 2) reference data, 3) base data, and 4) other data, respectively. The analysis results show that the layers are grouped into 5 to 7 factors according to the patterns. ANOVA reveals that the mean differences between the factors with high values and the other factors with low values under each pattern are statistically significant. Such high value factors under each pattern consist of similar layers, close to identical, with those under the other categories. This research proposes framework data system, including transportation, building, hydrography, elevation, administrative district, digital orthoimagery, geodetic control, and cadastral based on the analysis results. Proposed framework in this research will be a basis of establishing spatial data sharing system. For sharing proposed framework data in various fields, these data must be established and distributed as actual standard and also related future researches should be performed.
