(Headquarters: Nishi-ku, Osaka, President and CEO: Takashi Fujii, hereinafter referred to as "Sibilla"), which has high technological capabilities in the blockchain field. We are pleased to announce that the three companies will jointly develop a new credit information platform that utilizes blockchain technology and payment data.

■Background
With the advancement of information technology, we have entered an era in which large amounts of personal information are stored on the Internet. While it is predicted that the handling of personal information will continue to expand in the future, problems such as system failures, hacking by external criminals, and information leakage and falsification by internal criminals have become social issues. In addition, with the acceleration of the sharing economy, direct transactions between unknown individuals are rapidly increasing, and the credit information of individuals (transaction partners) is expected to become important in order to conduct safe and secure transactions. Due to these changes in the times, it is thought that there is a need not only for credit information that has been managed by traditional organizations such as financial institutions, but also for ``completely new types of information that can be used as credit information'' that are managed by non-financial institutions. Personal information management that ensures higher security, reliability, and traceability is required.

■About new initiatives
Insight has built a next-generation credit information platform that aggregates and manages multifaceted information by combining the know-how in rent payment agency that Insight has cultivated since its founding, lifestyle payment data such as electricity bills, real estate big data, and blockchain technology. Masu. This will allow users to easily prove their credibility that they have accumulated in their daily lives at any time, allowing them to receive more convenient services. In the first phase of development, scheduled to end at the end of January 2018, we will build a system that utilizes data storage on blockchain and data access using serverless architecture. This makes use of the features of blockchain technology such as tamper resistance, zero downtime, authentication based on encryption technology, data certification using electronic signatures, and data traceability, as well as the redundancy of the cloud, making it safe and secure. Highly available credit information management is achieved.

We have received comments from Microsoft Japan about the development of the credit information platform.

" Microsoft Japan Co., Ltd. welcomes the adoption of Microsoft Azure by Insight, SBT and Sibylla to develop a credit information platform that combines real estate big data and blockchain technology. We hope that this will not only enable the rapid construction of blockchains, but also accelerate the creation of next-generation credit information through data integration and analysis functions. We will continue to work with Insight, SBT, and Sibylla to provide innovative cloud environments that contribute to their customers' digital transformation."

■Future outlook
In addition to information management, in addition to the payment logs held by Insight, we also integrate real estate data and customer information held by real estate companies nationwide, open data held by the government, My Number information, and web services and mobile applications. We aim to build a new credit economic zone by integrating and analyzing social big data such as usage history and providing next-generation credit information.
