Preventing Personal Information Leaks Through Stronger Security Measures and Trainings

DOCOMO handles customer information for 58 million individuals and corporations, so we put special emphasis on security measures that protect against information leaks.
Employees with access to systems that manage customer information are kept to the minimum and information that can be handled by any one employee is restricted. Moreover, biometric authenticationnotice1 is required every time a system is used and usage logs are checked on a regular basis. In addition, the information is managed under encryption, which renders it useless even if taken out without authorization.
In order to further raise the awareness of employees regarding protecting personal information on the basis of these measures, we provide training for all employees and executives, including short-term contract employees, at least once a year. Training is also held at least once a year for the docomo Shops, and every month we check to ensure that information management is being conducted appropriately.

  • notice1 Biometric authentication is a mechanism for confirming a person's identity using physical characteristics such as fingerprints, facial features, color and voice. It is generally more foolproof than regular passwords.

[TOPIC] First in Japan to Acquire ISO/IEC 27011 Security Certification

In September 2010 we became the first in Japan to acquire certification for ISO/IEC 27011, a security standard for mobile communication providers, together with the safety standard on information security in the telecommunications sector for operation and maintenance of the CiRCUS system that provides the i-mode service.
Being certified means that the i-mode service, which is used by some 48 million customers, is provided under a robust security framework that guards against cyber attacks, network congestion, spam email, hardware and application malfunctions and other threats. However, information security risks are changing every day, so we will continue improving and strengthening security as a leading mobile communications company.
