I. INTRODUCTION
It is required taking an action for security incidents since network connected devices such as
PCs, Tablets, Smart-phones grew as core platform of education and research on institutes. In addition,
computer supported education is advancing recently [1]. Education on security literacy to users is the
best way to prevent security incidents with understand and act of users such as phishing, information
leak, targeted mail attack, illegal access, piracy, because it is limited that security barrier such as
firewall, anti-virus scanner, intrusion detection.
A number of effort have been made in recent years to develop education on security literacy.
These include face-to-face education by ICT division of university [2], educational videos [3, 4], and
game-based interactive contents [5, 6, and 7].
This paper is presented on International Conference on Human Computing Education and Information
Management System ( ICHCEIMS 2016 ) – Sydney, Australia on March 27 – 28, 2016
However, unlike the efforts made in many ways, very little attention was given to the
standardization of education contents and the visualization to make evidence data. In addition, it is
not enough to provide education by Japanese and English since there are more than 130,000 foreign
students in Japan [8]. Furthermore, though education for security literacy should be viewed as a
continuing process, technical difficulty and cost to keep upto-date these contents was reported.
The goal of this study was to improve education for security literacy in university by developing
sustainable contents and its deployment. This paper deals with an on-line e-learning activity applied
our contents from 2011 to 2015.
E-Learning which is not restricted by learner's location or time limitation have been employed for that
purpose. The e-learning contents we have developed is multilingual, based on common security
guideline in Japan, and took sustainability into consideration. Additionally, a kind animation
character joins to help us. "GakuNin'' authentication federation-enabled CMS (Course Management
System) was used for deployment the elearning for "Cyberethics'' to nationwide universities.
Our project has been carried out standardization, visualization and multilingualization of education on
security literacy in japan since GakuNinMoodle (https://security-learning.nii.ac.jp/) and "Learn with
Princess Rin Rin: Cyberethics'' was accessed from 102 institutes such as Kyoto University, Gunma
University, National Institute of Technology. In addition, it was found that a way to improve a
performance of CMS under the situation of massive access and downloading learning log.
II. METHOD
Our "Cyberethics'' education e-leaning project aimed at to learn anytime, anywhere by
standard contents. The contents have two appealing characters, "Princess Rin Rin'' and "Chu-Kichi''
shown in Fig. 1. That is why our project called "Princess Rin Rin Project''. Our three development
principles are, (1) Standard and visible; (2) Multilingual; (3) Sustainable. The detail are as follows.

(1) Standard and visible: The contents based on Japanese standard security education material,
"The Sample Policies for Information Security Measures for Institutions of Higher Education''
provided by National Institute of Informatics [9]. Namely, it is not needed to re-define inside contents
since the contents based on "The Sample Policies". Our contents provides topics as in Table 1 with 10
chapters and final exam, and each chapter goes on as follows:

Dangermeter: Pre-quiz to remind yourself on security literacy. (Fig. 2)

A True Story: Familiar examples of information security incidents. (Fig. 3)

Basic Information: An instruction to keep safe on information literacy. (Fig. 4)
This paper is presented on International Conference on Human Computing Education and Information
Management System ( ICHCEIMS 2016 ) – Sydney, Australia on March 27 – 28, 2016

Quiz: Review exercises corresponds to each chapter. (Fig. 5)
Moreover, by employing SCORM (Sharable Content Object Reference Model) [10] content package
which is a collection of standard and specifications for web-based e-learning, developing in standard
is enabled. And another point of our project, also common open-source CMS Moodle [11], make
visibility by processing learning logs.
(2) Multilingual: Japanese, English, Chinese and Korean version are developed with considering
cultural differences. It is not just translation since direct-translation from Japanese mild text may not
be enough to make foreign students understand. For example, we revise not only text and voice but
also figure and movie. In addition, taking simple and clear content is made in production of English
version to enhance understanding for non-native English speakers.
(3) Sustainable: Revision within section or page is allowed by using HTML5 wrapped by
SCORM as contents structure, and computer-generated voice software. SCORM package is suitable
for keeping updated since it is made from separated files such as manifest (imsmanifest.xml) which
defines its structure and e-resources such as HTML, mp3. Also computer-generated voice software is
useful to make and edit multi-language voice. It has been popular in everyday use such as station and
airport broadcast, voice of telephone customer service office.
A nationwide e-learning on Cyberethics by GakuNinMoodle which can be accessed from federated
institutions in order to pursue not copy distribution, but centralized contents management, started at
November 2012. GakuNinMoodle is authentication-federated LMS as shown in Table 2, so that
GakuNin is authentication federation framework based on Shibboleth [12] middleware in Japan.
GakuNinMoodle extended from original moodle has features as follows:

III. RESLUT
Fig. 6 shows the login and the unique login attempts of GakuNinMoodle from September 2013 on.
GakuNinMoodle was used by 102 institutions (Public university: 32, Private University: 52, National
Institute of Technology: 52, other: 3) as of Sept. 5, 2015. Overall login and unique attempts are
90,283, 27,840 respectively.

From the result, user activities on GakuNinMoodle increase and vary with large number of
institutions and course completion request from institution to users. For example, Kyoto University
promotes to learn security literacy by "Learn with Princess Rin Rin'' on GakuNinMoodle for all the
newcomers including foreigners. They reported that 78% in 2013, 81% in 2014, 85% in 2015

Management System ( ICHCEIMS 2016 ) – Sydney, Australia on March 27 – 28, 2016
newcomers complete the contents. Another example, National Institute of Technology that have 52
campus in many parts of Japan joined GakuNin authentication federation in 2014 in order to use
GakuNinMoodle, and decided to take "Learn with Princess Rin Rin:
Cyberethics'' for all faculty member until Sept. 2014.
The daily CPU load average of GakuNinMoodle in 2014 academic year are plotted in Fig. 7. The
results shows that the CPU load average approaches "25'' and the system fails to continue service with
access from National Institute of Technology just before their deadline, Sept. 2014. The improvement
of server performance successfully applied in Oct. 2014 to work around for massive access the course
until Oct. 31 2014, extended deadline: change of child process creation of HTTP daemon,
optimization of database memory usage.
IV. DISCUSSION
The goal of this study was to improve education for security literacy in university by
developing sustainable contents and its deployment. This paper deals with an on-line e-learning
activity applied our contents from 2011 to 2015.
Our project has been carried out standardization, visualization and multilingualization of
education on security literacy in japan since GakuNinMoodle and "Learn with Princess Rin Rin:
Cyberethics'' was accessed from 102 institutes such as Kyoto University, Gunma University, National
Institute of Technology. In addition, it was found that a way to improve a performance of CMS under
the situation of massive access and downloading learning log.
This is in contrast to previous e-learning on security literacy in which, problems that is a not
standardized content, difficult to keep up-to-date, targeted not to foreign student, were reported. In
our project, the actual improvement of security literacy education by providing standardized,
sustainable, multi-language e-learning contents on GakuNinMoodle which can used for federated
institutions in Japan, to solve these problems were made.
Further work is underway to analyze learning record and system log to improve contents with
an idea that the best way to improve e-learning is consider learner's behavior.
In conclusion, our GakuNinMoodle and contents, "Learn with Princess Rin Rin: Cyberethics'' have
sufficient feature to improve for e-learning on security literacy in Japan.
V. CONCLUSION
E-Learning which is not restricted by learner's location or time limitation have been employed for that
purpose. The e-learning contents we have developed is multilingual, based on common security
guideline in Japan, and took sustainability into consideration. Additionally, a kind animation

character joins to help us. "GakuNin'' authentication federation-enabled CMS (Course Management
System) was used for deployment the elearning for "Cyberethics'' to nationwide universities.
Our project has been carried out standardization, visualization and multilingualization of education on
security literacy in japan since GakuNinMoodle and "Learn with Princess Rin Rin: Cyberethics'' was
accessed from 102 institutes such as Kyoto University, Gunma University, National Institute of
Technology. In addition, it was found that a way to improve a performance of CMS under the
situation of massive access and downloading learning log.
From the development and the deployment, we can conclude; 1. Employing e-learning with
standardized contents can be the solution for improvement of security literacy education in university.
2. Though foreign students can understand Japanese, multi-language education is important for
universities in Japan that takes on a large number of them. 3. It is recommended that sufficient server
resource, examined plan for running CMS to deploy e-learning nationwide successfully because
performance bottlenecks will easily arise under the situation that many concurrent access and a large
number of database queries are reported.
