Protecting Customer Information Protecting Customer Information

We rigorously manage and monitor security to safeguard customer information from leaks and cyberattacks and to provide our customers secure products and services.

Protecting personal information

SoftBank gives significant consideration to human rights with the handling of personal information in accordance with the Act on the Protection of Personal Information and other legal frameworks in Japan. We are a corporate member of an accredited personal information protection organization (Japan Data Communications Association) and adhere to the Personal Information Protection Guidelines for telecommunications businesses, taking the lead in protecting customer privacy.

Governance

The CISO, which is composed of members appointed by the Board of Directors, takes the role of the personal information protection officer to implement the Personal Information Protection Management System - Requirements (JISQ15001). When the personal information protection officer receives a request regarding personal information from an administrative authority, the officer is responsible for confirming the validity of the request. In accordance with laws and regulations, we obtain the consent of the individual concerned before providing the person’s information to a third party.

Personal Information
Protection Management System

In order to prevent personal information-related human rights violations, SoftBank follows the Personal Information Protection Management System, limiting the acquisition, use and provision of human rights-related information, and carrying out regular risk assessments regarding the appropriate use of such.

When a risk is detected, we take appropriate action and follow up by monitoring and making constant improvements to minimize the risk. If a human rights violation occurs in relation to personal information, we promptly investigate and implement necessary corrective actions. If a human rights violation occurs in relation to personal information as a result of providing that personal information to a third party, we take necessary measures, including, but not limited to, setting up a point of contact to offer remediation to the individual concerned.

Reports

There were no cases of complaints or violation of laws regarding personal information leaks in FY2019. SoftBank will provide notice on our website in the event that any violations of laws or regulations occur, such as leaks of personal information.

Rigorous
information management

Rigorous information management

SoftBank has established five-tiered security areas ranging from level 1 to 5 in our facilities, applying strict controls in accordance with each level. Levels 3 and above are considered “high-security areas.” Significantly important data, such as personal information and telecommunications secrets, are exclusively handled in these areas.

For example, in the Customer Support Center, which is designated as a high-security area, we strictly control security under the rules specifically designed for these areas, authorizing entry and exit to the facilities by security guards and passes, and keeping prohibited items from being brought in to the facilities.

Additionally, our operations fully adhere to ISO27001, the international standard for information security management systems. We undergo an external audit twice a year based on ISO27001 to confirm that our information security management is appropriately run, including compliance with our Privacy Policy.

Spam mail

To protect against malicious e-mails such as spam and fake bills unexpectedly sent to mobile phones or smartphones, we automatically examine the content of these e-mails based on our accumulated database of spam and provide our customers with spam filters that block the receipt of these kinds of e-mails. We have also set up a reporting center where our customers can report any spam e-mails they have received by simply forwarding them. When it is confirmed that they were sent from a SoftBank registered address, we may take strict measures against the address owner, including suspension or cancellation of our service.

Unauthorized access

There are increasing cases of malicious third parties gaining unauthorized access to personal information, such as bank account numbers, credit card numbers, and login IDs and passwords, after customer devices are infected with viruses or they access URLs in the bodies of e-mails. We are strengthening security to protect our customers' personal information by preventing stolen information from being used for unauthorized access to My SoftBank and My Y!mobile member sites, where they can manage their accounts.

Passcode

Customers can change their settings in such a way that the passcode they specified when signing the contract is required for logging into My SoftBank or My Y!mobile.
