Kaula develops “Document Eigen Framework” to make Self-sovereign Private data stores


Kaula have been developing and introducing Factom and its unique autonomous blockchain for record managemen of any documents and data. Factom is so powerful and easy to use to build applications and to add blockchain capability to existing applications. Kaula applied Factom to access record management of  Japanese Security number system in local govenments.

Through this business Kaula has been noticed that we need some secured private data store of such as healthcare, academia, etc. It should be self-sovereign, managed by himself (herself) but not by any third parties, could be modified (corrected) and deleted (forgotten if case data were not longer required).
The above capability is so widely needed. We call it “Passports” and its embodyment is Medical Passport (for healthcare segment), Academia Passport, Govenment Passport and so on.

Kaula’s “Document Eigen Framework” (EDF)

Kaula develops “Document Eigen Framework” to easily build such Passports. Plese see the figure below.
Any access footprints, including creat, update and erase, are kept in Blockchain ( such as Factom) and it is anti-tamperd, transparent and auditable. The private data themselves are stored in any place accoring to user requirements, sometimes in local store, sometimes in public store with encryption. Passport ID is given to the personal, and SSO is coordinated.
It is self-sovereign, poratble, completely managed by the personal, and GDPR-compliant.
It addition, EDF supports “Trustee model” as well.

Document Eigen Framework

“Document Eigen Framework” will be soon available for application builders.

Business alliance between Kaula and AZAPA

Business alliance between Kaula, Inc. and AZAPA Co., Ltd. aiming to build blockchain technology and service in the automotive market

Kaula, Inc. (HQ in Chiyoda-ku, Tokyo, CEO: Katsuji Okamoto, hereinafter referred to as “KAULA”), a blockchain technology company, and AZAPA Co., Ltd., (HQ in Nagoya, Aichi-ken, CEO & President: Yasuhiro Kondo, hereinafter referred to as “AZAPA”), a leading company in the automotive field, have concluded a business tie-up. We will work on development of practical application services that increase economic values of data derived from automobiles by adapting the blockchain technology.

Background of the Alliance
A paradigm shift of the automotive market is near at our hand, especially due to China’s EV shift. Regulations on CO2 emission is being required around the world to solve serious air pollution problems, shifting from gasoline cars to electric cars is going on and EV battery management attracts attention now.
Battery is the heart of EV. It is the most expensive, heaviest and dangerous. KAULA and AZAPA together will make a new sharing economy around the battery to maximize its value and manage its life cycle, acquiring battery residual value data, distributing battery usage forecast using AI and writing them into the blockchain to guarantee authenticity and non-tampering.

Overview of BRVPS
The Battery Residual Value Prediction System (BRVPS) acquires data from BMS (Battery Management System) such as temperature, humidity, pressure, voltage, current, etc. in the battery unit and information from OBD (On-Board Diagnostics) and then stores them in the battery residual value forecast engine. BRVPS steadily executes AI/ML and writes the results to blockchain which EV/battery owners and users can access via cloud services. This enables you to extract the maximum battery value through freely accessing the present and future SOH (State of Health), including charging efficiency, and usage forecasts based on the past battery usage tendency.

The Next Deployment
Through cooperation with EV and battery manufacturers, we aim to develop new markets centering battery data. Implementing each step of EV and battery supply and demand balance, energy consumption planning, reservation, use and settlement, we accelerate the spread of EV and create additional services so that EV and battery owners and users can switch from consumers to prosumers.
In addition to the rising of global environmental consciousness, automatic driving and other technologies, newly services have been born and growing rapidly. We will broadly provide highly value-added services through KAULA’s blockchain technology and AZAPA’s automotive technology and network to build a new business model together.

Establishing a Consortium
We will set up a consortium to form an ecosystem, ahead of mega platform formers, to establish “IoT-blockchain based technology” aiming at a practical service model which covers from sensing to data utilization.
The paradigm shift surrounding automotive industry is progressing and closely related to the deepening of IoT, and the economic value of data obtained from automobiles has already been widely acknowledged. The current telematics, however, the type and granularity of acquired data are not standardized and its service is so limited. We will together promote applications created by utilizing data and their standardization including blockchain and security as backplane technologies.

Applying Blockchain to IoT ( ABC Strategy)

Kaula tries to apply Blockchain technology to Internet of things arena.
We see four technologies in the digital transformation recently emphasized. First of all, field data are gathered at IoT site. Because they are usually big data, they are processed as such. Next, the data should be analyzed by smarter algorithms (sometimes called as AI) to identify the essential factors, and then stored in Blockchain and shared by stakeholders in secured and non-tampering manner  to form applications. The following Figure 1 shows these four items and value transmission among them, which leads to data circulation and yields additional applications.

Figure 1. Four technologies in the digital transformation

Kaula thinks it important to process this value transmission in a connected and consistent manner because IoT application needs “total engineering” and because the four technologies are still treated separately.

Moreover, Kaula identifies that there are characteristic differences among AI and Blockchain which are applied to IoT applications. Blockchain is a technology to extend usages. While IoT enlarges of the physical world that we can treat, Blockchain enables new stakeholders to join in and share the value chaining. On the other hand, AI is a technology to make the data more valuable and more competitive. Figure 2 shows two axes; Deepening of solutions (A axis by AI) and Extension (BC axis by Blockchain) with their contour of solution value. Please note that the shape of the contour is concave.

An example is that data from IoT can be stored in safe and non-tampering to be used by new stakeholders with their business models. But Blockchain does not say anything, if the input data is true or not. Some data checking by AI which also sees other environmental data can add a value that the input data is true. (Revised)

“Usage record management system utilizing Factom’s blockchain solution”



Press release: a joint development with Atrris

Kaula Inc. and Atrris Corporation have formed a joint development of a usage record management system utilizing Factom’s blockchain solution

The initiative will retain record authenticity and tamper resistance to data processing of the Japanese social security system.

TOKYO, JAPAN (June 13, 2017) – Kaula Incorporated (Head office: Chiyoda-ku, Tokyo, Representative Director, Katsuji Okamoto), a blockchain platformer, is pleased to announce that Kaula and Atrris Co., Ltd. (Head office: Setagaya-ku, Tokyo, Representative Director, Masanori Yasumitsu), who has been developing personnel, payment, accounting and medical logistics systems, have agreed to jointly develop a “usage record management system” against data involved in the above applications using Factom blockchain. Using this system, you can retain authenticity and tamper resistance of log records generated when the Japanese social security system’s data is processed – when information is added, updated, deleted or retrieved in mission-critical applications. Kaula and Atrris will also jointly promote business around the usage record management system.

Background of Collaboration

Recently, blockchain technology has received attention because of its great potential to drastically change the way we do business and the impact it will have on society. Blockchain has become the solution requested to achieve record authenticity or tamper resistance against processed results in mission-critical applications that Atrris develops. Kaula and Atrris have been investigating ways to conquer this requirement, where they use their knowledge combined with Factom’s blockchain technology, a data layer blockchain product, for use cases that office staff of local government access data of the Japanese social security number system. Now that Kaula and Atrris have completed a PoC (Proof of Concept) and confirmed that their jointly developed usage record management system can retain log record authenticity or tamper resistance, both companies will proceed to a next step of experimental proof with their customers, and then will apply the system to business applications.
In addition, by using Factom you can more securely and surely manage, track and audit various kinds of documents or records such as log records in general, loan records, securities or insurance contracts and medical data and others in a decentralized way than legacy centralized systems. Kaula and Atrris will widely and jointly promote the usage record management system to these business areas.

Note: Factom is a blockchain framework developed and provided by Factom, Inc. whose head office is located in Austin, TX, USA. Factom is on a mission to give the world’s systems authenticity. People and institutions today can solve hard problems and change the world for the better when they have a reliable framework to build upon.
