Objective: Service industry has become the most important industry among various economic activities, as the percentage of service related industry in advanced nations is over 60% of their GDP and the percentage of service industry in South Korea, a traditional manufacturing nation, now takes up over 60% of the entire economy. Background: Such industry paradigm shift has changed consumers from those that simply purchased products into groups of people that evaluate the companies that manufacture products, thereby further intensifying competition among companies and increasing the importance of integrated communication between companies and consumers. However, the excessive existence of sub-identities that have been developed for integrated management of the existing corporate identities, as well as the undifferentiated general management strategies by companies are creating confusion not only for consumers but also for various corporate interest parties. In addition, service identity strategy has become the most important strategy than any other sub-identity strategies in forming corporate identity at the increased importance of corporate service in the era of service industry. However, the current domestic circumstance is that the concept of service identity has not been well established through specific related studies. Method: Accordingly, the existing academic and field studies on the corporate identity(CI), brand identity(BI) and product identity(PI) used for the communication with consumers were reviewed in this study to establish and summarize the concept of service identity(SI) that appeared at the service economization. Results: The purpose is to examine the kind of change that could be brought about by SI for the corporate integrated identity strategy developed through the existing corporate, brand & product image in order to present a new direct in corporate identity strategy according to the industry paradigm shift through a SI centered new corporate identity framework. Conclusion: For preparing the new era of service industry, the corporate integrated identity strategy must be integrate with concept of service identity and which is essential to differential from other companies. Application: The proposed concept and framework of service identity on this paper will help to understand and clearly define why service identity is important factor of the new idea of corporate identities.

Openstack is widely used as a representative open-source infrastructure of the service (IaaS) platform. The Openstack Identity Service is a centralized approach component based on the token including the Memcached for cache, which is the in-memory key-value store. Token validation requests are concentrated on the centralized server as the number of differently encrypted tokens increases. This paper proposes the practical Byzantine fault tolerance (PBFT) blockchain-based Openstack Identity Service, which can improve the performance efficiency and reduce security vulnerabilities through a PBFT blockchain framework-based decentralized approach. The experiment conducted by using the Apache JMeter demonstrated that latency was improved by more than 33.99% and 72.57% in the PBFT blockchain-based Openstack Identity Service, compared to the Openstack Identity Service, for 500 and 1,000 differently encrypted tokens, respectively.

Identity authentication sharing technologies which allow many service providers to share the result of identity authentication of an identity provider receive high attention as alternatives for current problematic identity authentications in the next-generation Internet environment, since they can provide crucial advantages including high usability, cost effectiveness of service providers, and privacy protection. However, in order for the identity authentication sharing technologies to be widely deployed in global Internet scale, the interoperability problem among different identity authentication sharing protocols and the trustworthiness issue among the participating identity providers, service providers, and users should be resolved in advance. This paper firstly analyzes current status of the protocol interoperability issue and existing trust frameworks for identity authentication sharing. And then, based on the result of analysis, this paper proposes a next generation identity authentication sharing architecture for global Internet.

In this paper, we propose to improve the designation examination criteria of agencies that provide personal identity proofing based on the resident registration number (RRN), a 13-digit number uniquely assigned by the government to identify Korean citizens. In online commerce, etc., the personal identity proofing agency (PIPA) is a place where online users can prove their personal identity by presenting an alternative means instead of their RRN. The designation examination criteria for PIPAs established in 2012 is a revision of the relevant current laws, and there is a problem in applying the designation examination for alternative means of RRN as the current examination standard. Therefore, in this paper, we propose a method to make the current examination criteria applicable to the newly designated examination of the personal identity proofing service provider based on the current RRN alternative method. According to the current designation examination criteria, only those who satisfy all the examination criteria are designated as the PIPA. However, in reality, it is not in line with the purpose of regulatory reform to require that all examination criteria be satisfied. In the proposed method, it is proposed to apply the standard score system for designation of PIPAs, to make the law current, to secure legal compliance, and to establish a new examination standard to provide a new alternative means of personal identity proofing service. By applying the proposed method to the PIPA designation examination, various alternative means of RRN can be utilized in the online commerce service market.

As expanding of service robots into the human life, the needs of robots are increased. The experts group forecasted that the robot market would grow rapidly in a short time, robot companies should compete with others for prior occupation in a market. In this research, we proposed a framework of robot identity design based on building methods of product identity and developed a case study. Identity is one of the strategies to distinguish from competitors through managing image united. It is possible to apply this identity approach on robot area, which was used for making image of companies, brands, and products. In general, identity has visual, invisual features, which can be classified into three elements; Robot Philosophy, Functional Affordance, Family Look. Robot philosophy means the vision or philosophy of a company through robot development, functional affordance is a character or role to serve and family look includes visual design elements like as shape, color, material, graphic, behavior etc. We suggest that this guide will be applied to build identity of following series of a model, models of same service group and all models of a company or commercial space.

Each cloud service has numerous owners and tenants, so it is necessary to construct a privacy preserving identity management and access control mechanism for cloud computing. On one hand, cloud service providers (CSP) depend on tenant's identity information to enforce appropriate access control so that cloud resources are only accessed by the authorized tenants who are willing to pay. On the other hand, tenants wish to protect their personalized service access patterns, identity privacy information and accessing newfangled cloud services by on-demand ways within the scope of their permissions. There are many identity authentication and access control schemes to address these challenges to some degree, however, there are still some limitations. In this paper, we propose a new comprehensive approach, called Privacy pReserving Identity and Access Management scheme, referred to as PRIAM, which is able to satisfy all the desirable security requirements in cloud computing. The main contributions of the proposed PRIAM scheme are threefold. First, it leverages blind signature and hash chain to protect tenant's identity privacy and implement secure mutual authentication. Second, it employs the service-level agreements to provide flexible and on-demand access control for both tenants and cloud services. Third, it makes use of the BAN logic to formally verify the correctness of the proposed protocols. As a result, our proposed PRIAM scheme is suitable to cloud computing thanks to its simplicity, correctness, low overhead, and efficiency.
