Main opinions from the members (summary)

Attachment 1: Status of Efforts to Install My Number Card Functions in iPhones

  • Speaker: You mentioned that the number of smartphone use in Recently, I feel that My Number Card is becoming an increasingly important part of the infrastructure, including health insurance cards and driver's licenses. However, there are many cases in which a certain number of online articles and comments have caused misunderstandings, so it is necessary to explain to the outside world. It is also necessary to explain to the general public, but if we do not carefully explain to experts who are familiar with the issue to some extent, there is a possibility that it will be misrepresented.
    • Secretariat: The system configuration and other details related to the smartphone are not disclosed at this time, but when the time comes when they can be disclosed, we will carefully explain them to the general public as a whole and to experts.
  • Speaker: You mentioned that the number of smartphone use in My Number Card and smartphones. In addition, JPKI built a signing electronic certification mechanism using GP-SE, but it is necessary to explain the background of adopting mdoc this time. It seems that it was adopted with an eye on future expandability (use of driver's license and health insurance card) and international standards, but I feel that it is necessary to publicize the background from this stage.
    • Secretariat: attributes, mdoc and OpenID for VC. We will create a document that briefly explains the background of adopting mdoc, its security, and how it will expand in the future, including international standards and European trends.
  • Speaker: You mentioned that the number of smartphone use in As you mentioned earlier, information should be as open as possible. For example, whether iPhones can be used for tax returns next spring is a matter of concern. In addition, convenience store use, driver's licenses, and health insurance cards will be important use cases in the future. My Number Card readers are already widely used in hospitals for health insurance cards. It was explained that coordination was being made between Ministry of Health, Labor and Welfare and verification test, but it was not possible to know when it would be time for Apple to respond. It is important to proceed with the story that smartphones can be installed in hospitals with the help of politics.
    • Secretariat: At present, we are aware that information about My Number Card on iPhones is not being provided to users. We aim to release the beta version of the specific certification or the usage flow and technical materials around the end of March. We will also improve the accuracy of the UI/UX image and use case assumption a little more, publish them as soon as possible, and fulfill our responsibility to inform the public. At hospitals, in addition to My Number Card, smartphones can be used as health insurance cards. We are currently preparing to use a general-purpose reader as an external device in addition to the card reader with facial recognition set in the hospital. Ministry of Health, Labor and Welfare has announced a schedule for verification test so that it can be used for both Androids and iPhones at an early stage when services equipped with My Number Card on iPhones start. Digital Agency also wants to make sure that people know about it, including support. As for e-Tax, Android-compatible services have started this spring, but we are considering whether iPhone-equipped My Number Card will be compatible next spring. We will coordinate diligently with National Tax Agency. Driver's licenses can be integrated with My Number Card's driver's licenses from March 24, but the timing has not been decided because the driver's licenses will be installed on smartphones separately. In cooperation with the Metropolitan Police Department, Priority Plan plans to install driver's licenses using this mdoc issuance management system.
  • Speaker: You mentioned that the number of smartphone use in I would like to know if there are differences in UI between Android and iPhone, or if there are no differences in general. I think that use cases using mdoc in the private sector are very important, but I think that it would be better for the private sector to regulate to some extent, such as plans to provide SDK and standardization of UX. I would like to ask if there are such plans or product arrangements.
    • Secretariat: There is currently a difference in the UI between Androids and iPhones. When developing the app this time, we reviewed the UI and made changes to it in accordance with Digital Agency's design guidelines. We plan to consider Androids based on these guidelines in the future. Regarding the provision of SDKs, etc., there are those provided by Apple Inc. and those prepared by Digital Agency for the face-to-face and non-face-to-face (online) versions. Although the contents differ between the face-to-face and non-face-to-face versions, we are preparing not only the software but also the specifications as a verification program under the Number Act.
  • Speaker: You mentioned that the number of smartphone use in Regarding the UX, I feel that it has become much easier to use compared to JPKI's Android-based version. On page 6 of Exhibit 2, it says that you need to enter your password, but I would like to ask how the UX is conducted when you want to use FaceID without entering your password.
    • Secretariat: user identification certificates online, but biometric authentication and 4 pin for smartphones are also available. Regarding the UI, Exhibit 1 explains the Mynaportal login method. Although FaceID login is set as the first primary method, users can select another method if they wish. When using FaceID, there is a button to log in with FaceID on the first screen of Mynaportal, and FaceID starts up immediately when you press the button. We will consider improving it in the future while listening to the voices of each company and citizens.
  • Speaker: You mentioned that the number of smartphone use in , in addition to health insurance cards and others, there was a guidance for private use. When private business operators perform identification and identity verification, various spoofing occurs in eKYC. Therefore, I would like to ask for every effort so that not only JPKI but also identity verification by private business operators using mdoc can be used very easily and safely. I think it will take time to prepare for the development of the competent ministerial ordinance, but the use in financial services in particular is highly expected. I would like to ask for every effort so that iPhone-equipped My Number Card using mdoc can be used in identity verification online as soon as possible.
    • Secretariat: eKYC include the Act on Prevention of Transfer of Criminal Proceeds and the Act on Prevention of Improper Use of Mobile Phones. There is a high risk of spoofing, such as copying, in non-face-to-face identity verification, but there are public comments on policies to eliminate it. The Act on Prevention of Improper Use of Mobile Phones, which is under the jurisdiction of Ministry of Internal Affairs and Communications, is expected to come into force in about a year, and the Act on Prevention of Transfer of Criminal Proceeds is expected to come into force in about two years. In addition to presentation by My Number Card and electronic signatures by My Number Card, the content of transmission of electromagnetic records as a substitute for cards is being studied. Public comments will be made in time for the release, and transmission of electromagnetic records as a substitute for cards will be promoted as one of the methods listed in the ministerial ordinance.
  • Speaker: You mentioned that the number of smartphone use in is as valid as a registered seal, so it should not be used lightly, but the situation is that it has not been communicated to the entire public. Looking at the operation screen on the app side, I feel uneasy that such a warning is not displayed anywhere. I recognize that it is better to have a screen transition so that I can warn and obtain approval before signing at least before entering a signature. I would like you to do your best to understand the people. I would like you to consider the direction of certification, etc., protection and risk perspectives, etc., including the point of the legislative fact of My Number Card.
    • Secretariat: Although the materials presented this time have been simplified and have caused misunderstanding, we are working with Ministry of Internal Affairs and Communications on "Other Services Screen" on page 9 of Exhibit 1 to clarify the subject of signatures and to take concrete measures as much as possible regarding the nature of validity equivalent to registered seals. Since it is currently under construction, we will consider and confirm it again based on Dr. Miyauchi's points.
  • Speaker: You mentioned that the number of smartphone use in In the case of face-to-face use, an mdoc reader is required, but it is usually assumed that an mdoc reader is certified and provided. If there are any policies on the provision and operation of such a reader, I would like to know. Regarding signature verification of mdoc, certificates must be provided, but I would also like to know about the handling policy in the case of mdoc.
    • Secretariat: Regarding the provision of certification for mdoc leaders, institutionally, Digital Agency will create a confirmation application and provide or certify it. In concrete terms, Digital Agency will formulate a corresponding library for the program. Digital Agency is in the process of establishing a certification procedure for businesses that want to build their own without using the library. We are in the process of establishing a procedure that will simplify the series of procedures such as the application method, NDA, and test environment, simplify the application procedure, implement the library correctly, and meet the requirements of the law. We plan to present a beta version in the near future. In this way, both face-to-face and non-face-to-face, we will have service providers thoroughly verify and confirm the applications required by the law, or confirm what kind of services they will use.
  • Speaker: You mentioned that the number of smartphone use in , a face photo is supposed to be scanned for facial recognition, but if a face photo is scanned, the face app is required, and the current My Number Card allows passwords or PINs to be set separately, so two passwords or PINs should be input.
    • Secretariat: for signatures are required to enter the electronic certification. The My Number itself can be used as a reference number when accessing the application for assistance in entering information on face sheets. Therefore, the method described in Appendix 1 was adopted.
  • Speaker: You mentioned that the number of smartphone use in In May 2023, when electronic certification in My Number Card was equipped with Android-based smartphones, Digital Agency asked telecommunications carriers through industry groups what to do if they lost or sold their devices. Telecommunications carriers, including MVNOs, make announcements when they lose or sell their devices by referring to the Digital Agency website. In the future, we would like you to make requests as soon as possible if you need to make additional responses to iPhones. In addition, as individual responses will continue to be made by referring to the Digital Agency website, we would like you to prepare contents so that iPhone users will not be confused.
    • Secretariat: We are grateful for the cooperation of mobile shops and websites regarding Androids. Regarding the installation of My Number on iPhones, we will revise leaflets and websites. We would like to ask for your continued cooperation in disseminating information, etc. We would like to ask you again.
  • Speaker: You mentioned that the number of smartphone use in There is an explanation that the explanatory materials will be divided into those for the general public and those for experts, and I think it is better to do so. On the other hand, there are cases where it is desirable not to necessarily say the explanation for experts to the general public. If you convey difficult content for experts to the general public, it may be interpreted in the opposite sense, as if you are blurring or hiding it. Please be careful because even if you use the same word or keyword, it may be understood differently.
    • Secretariat: and those for experts might be received differently. We would like to ask for your guidance on how to put together the explanations in concrete terms.
  • Speaker: You mentioned that the number of smartphone use in , we would like you to consider ways to communicate to the people in an easy-to-understand manner depending on the usage scenario, such as creating a video for health insurance cards that can be watched while waiting at medical institutions or dispensing pharmacies, etc., and for driver's licenses that can be watched while waiting for online reservations or renewals, etc.
    • Secretariat: Health Insurance Card is linked to Ministry of Health, Labor and Welfare and Driver License is linked to National Police Agency on a daily basis, so we would like to consider including the creation of an easy-to-understand video for the public.

Attachment 2: Operation at the time of occurrence of the Incident Information, etc.

Appendix 3: Operating Status of electronic certification Service for Android-based Smartphones

  • Speaker: You mentioned that the number of smartphone use in , haven't you aimed to eventually eliminate the need for paper certificates of residence, etc. by providing electronic certification? Please tell us your future position and direction.
    • Secretariat: The current Convenience Store Certificate Issuance Service, which is available late at night and on holidays, has been very well received. It has also reduced the paperwork at the counter, and the benefits are clearly increasing. It is a highly reputable service that is used in 10 million cases every year, and the number of users is increasing. However, while administrative agencies can link their My Number information in their backrooms, it is difficult to link private sector's backrooms, and it is difficult to roll it up. Regarding convenience store issuance, we are considering not only paper issuance but also digital issuance and digital attachment. You are aware that we need a direction that paper should be eliminated, but we would like to consider it while receiving guidance from not only the government but also the private digitalisation.
  • Speaker: You mentioned that the number of smartphone use in convenience store delivery services is low. If there is aggregate data on the number of Mynaportal logins using Smartphone JPKI, that number would be relatively high. It would be good to present data that can show that such smartphone use is effective.
    • Secretariat: At the next meeting, we will share information such as the number of logins using smartphones.
