In this proposal, we aim to enhance the security of systems accounts by improving the authentication techniques. We mainly intend to enhance the accuracy of the one-time passwords via including voice biometric and recognition techniques. The recognition will be performed on the server to avoid redirecting voice signatures by hackers. Further, to enhance the privacy of data and to ensure that the active user is legitimate, we propose to periodically update the activated sessions using a user-selected biometric factor. Finally, we recommend adding a pre-transaction re-authentication which will guarantee enhanced security for sensitive operations. The main novelty of this proposal is the use of the voice factor in the verification of the one-time password and the various levels of authentications for a full-security guarantee. The improvement provided by this proposal is mainly designed for sensitive applications. From conducted simulations, findings prove the efficiency of the proposed scheme in reducing the probability of hacking users' sessions.

The Internet of Things (IoT) applications are quickly spread in many fields. Blockchain methods (BC), defined as a distributed sharing mechanism, offer excellent support for IoT evolution. The BC provides a secure way for communication between IoT devices. However, the IoT environments are threatened by hacker attacks and malicious intrusions. The IoT applications security are faced with three challenges: intrusions and attacks detection, secure communication, and compressed storage information. This paper proposed a system based on double-blockchain to improve the communication transactions' safety and enhance the information compression method for the stored data. Information security is enhanced by using an Ellipse Curve Cryptography (ECC) considered in a double-blockchain case. The data compression is ensured by the Compressed Sensing (CS) method. The conducted experimentation reveals that the proposed method is more accurate in security and storage performance than previous related works.

Blockchain and its infrastructure technology have expanded rapidly in the last decade and are in high demand, but there is a lack of comprehensive studies on those platforms. Blockchain is a new technology based on the distributed digital ledger system. Decentralized trust is one of the key factors behind the blockchain-based system. Transparency of such a system is better than a conventional centralized ledger system. By using a blockchain-based transaction system, any business organization can harness key benefits like data integrity, confidentiality, and anonymity without involving any third party in control of the transactions. Since the blockchain is used in numerous applications and the horizon is expanding at an unprecedented pace. So, there is a need for an introducing and reviewing of blockchain platforms. In this paper, we have reported a review on existing contemporary blockchain platforms. In particular, From the existing studies, we have identified eighty blockchain platforms and the majority of them have a lack of technical details. To provide the researchers a comprehensive introducing on blockchain platforms to perform a broad guideline for future research and investment in the blockchain domain.

Arbitration is an essential methods of settlement for disputes in international commercial transaction. UNCITRAL Arbitration Rules have been in force after adoption in 1976. Over the 30 years, UNCITRAL Arbitration rules have been modeled for domestic and international arbitration institutes for setting and revision on their arbitration rules. UNCITRAL Committee has published the revised Arbitration Rules which entered into force after 15 August 2010. Therefore new version of arbitration rules are substituted for the previous version of UNCITRAL Arbitration Rules 1976 since its enforcement. The revised arbitration rules of UNCITRAL have been changed in various items for convergence with new trends and modern practices on arbitration including information communication and technology. The revision of arbitration rules focused on resolving problems in practice and codifying best practice to enhance the efficiency of arbitration conducted under the rules. There are considerable in a number of important respects on the removing the restricted in writing requirement for information technology, adapting the multiparties arbitration, joinder arbitration, truncated arbitral tribunal and adjustment in terms and condition and construction simply. Also a number of provisions have been refined, varied and clarified with new articles included. Conclusively the new revised arbitration rules fill a number of gaps which became apparent in the UNCITRAL Arbitration Rules 1976 to bring into line with new modern practices of international arbitration rules in international commercial disputes. This paper focus on the study the problems and inspired points on significant revised provisions and its considerable points in arbitration environment. This paper is approaching to the comparisons of UNCITRAL revised Arbitration Rules 2010 with previous Arbitration Rules 1976 of UNCITRAL and International Arbitration Rules 2011 of KCAB.

The purpose of this study aims to the implications by the introduction of TSU/BPO system as a instrument of trade settlement. Jointly with financial messaging provider SWIFT, the ICC Banking Commission has developed the URBPO to take into account the legitimate expectations of all relevant sectors. Once the goods have been shipped, the seller's bank uploads the shipping and logistics data to the TSU to be checked against the baseline. URBPO is the first ever set of standards in supply chain finance that governs BPO transactions worldwide. BPO enables banks to reduce the risks associated with international trade to the benefit of both buyers and sellers. A BPO is an irrevocable undertaking given by an Obliger Bank to a Recipient Bank to pay a specified amount under the condition of a successful electronic matching of data or acceptance of mismatches. The BPO should be viewed as an exercise in collaboration between trading partners and their banks. Drawings upon global standards and incorporating the benefits offered by letters of credit, the new instrument has the potential to benefit all parties in a trade transaction-and bring trade settlement into the 21st century.

Under the circumstance of increasing international trade volumes and limitation of customs human resources, it is necessary to shift the customs' revenue collection activities and audit method from a transaction-based approach to an account-based approach. Thus, in 1997, U.S. Customs services established the Account Management Program. The Account Management Program is designed to increase importer compliance and improve customer service through one-on-one interaction with business entities and a designated Customs representative(Account Manager). The Account Management Program is a comprehensive process that includes the following stages and activities ; selection of a potential Account, establishment of the Account, management of the Account. In 2009, Korea Customs service introduced and executed the Account Management Program. But owing to its early stages, Korea Customs service does not suggest effective direction of development of the AM program. So I can propose the following improvements of the Account Management Program in Korea. Firstly, the Account Managers have to be assigned more traders than AEOs(Authorized Economic Operators). Secondly, it is necessary that Customs service appoints part-time port Account Managers to help more traders to improve customs compliance. Thirdly, thought should be given as to Account can be expanded to encompass both small and medium enterprises(SME) by providing customs brokers managing their customs business on the behalf of the SME with the Account Managers. Lastly, Customs service has to establish performance measures and action plan for the Account Management Program.

There is no doubt that electronic commerce facilitates international trade and lower transaction cost and help firms make the best of the opportunities of market access. The comprehensive programs had been implemented to provide better electronic commerce environments by international organizations such as OECD, UNCITRAL, APEC and etc. Especially, WTO plays the most important role to implement efficient forms and rules on electronic commerce after Seattle 3rd Ministerial Conference. Member countries recognize the need to conduct the electronic commerce in compliance with the principles and rules of WTO. However, there are many issues to be solved such as the clarifications of concepts and definitions, the possibility of adaptation of technological neutrality In GATS, the Imposition of taxation in electronic commerce transactions and the methods of protecting copyright as well as trademark. The Implementation of concrete forms and rules of electronic commerce in the WTO will be influential to international trade as the member countries have to adapt them In their transactions. Considering that further discussion will be continued in GATS, we need to analyze the problems and strategies for electronic commerce.
