Registration system of cloud campus by using android smart tablet

Recently the university is required to check exactly the record for attendance of their student, because Ministry of Education, Culture, Sports, Science and Technology in Japan imposes the ratio of attendance as approving credits. The chronic truancy students receive fewer hours of instruction and tend to cut classes. We know the chronic absenteeism is not the main reason of academic failure, but it remains one of many reasons of leaving school (Rothman2001). The relationship between student and university may be important factor for the problem of Chronic absenteeism, truancy and academic failure.

According to the change of social environment such as more relaxed education policy in Ministry of Education, Culture, Sports, Science, and Technology, it is required that university needs to be more student-centered and supportive of students with different needs.

Recently, the attendance management system (AMS) with Radio Frequency IDentification (RFID) technology has been developed as a part of Smart University (Mitchell et al.2003, Ueki et al.2005), which develops the educational infrastructure using high technologies, such as ICT. However, the reader/writer for Felica is too expensive to build the AMS. Furthermore, the reader/writer is set at each lecture room and the teacher cannot witness the student’s authentication of the ID card, so that, we may meet that one of friends instead of the person in question can answer the roll call for an absentee.

Near Field Communication (NFC) is one of international wireless communication protocols and data format in the communication. For example, the RFID standard is well known wireless data communication method. In Japan, Felica card is a popular way to identify the unique ID. NFC technology includes not only Felica but other type of IC chips. The Android OS 2.3 and the later can provide access to NFC functionality library. Although the Nexus series such as Nexus4, 7(2013) & 10 are not compatible with Mifare classic tags. However, they can detect the UID code of a tag. If we develop an application which has the ability to just detect a tag and read it’s UID code, and then launch settings/profiles/etc then we can still use Mifare Classic tags. Accordingly, we developed AMS Android application by using Nexus series with NFC (Ichimura and Kamada2013, Kamada and Ichimura2014a,b). Because Nexus 7 is a low cost smart tablet, a teacher can determine to use familiarly. Any teacher, who calls the roll at the class, can free from stress before the lecture. Especially, this paper describes the method of early discovery for chronic non-attenders by using NFC Bluetooth Handover between PC Linux and Android. The attendant records can be collected from different Nexus 7 and then the data are merged into a SQLite file. The system reports a summary sheet to operate with the trunk system in educational affairs section.

Our university has been developing the cloud campus service system to create or produce the information flow as a bridge between our university and the local community. The cloud service system provides to permit an efficient flow of knowledge and intellectual ability between communication network as flow of electronic information and as flow of interpersonal relationship. The system consists of Social Network Service (Kazu-fuku2011), File Sharing Service (Karlitschek et al.2012), Video Streaming Service (ViMP GmbH2010), and Video Conference Service (Wagner et al.2006).

The section Near field communication describes the RFID and NFC specification. In the section NFC attendance management system, the functions of our developed NFC Attendance Management System will be described. Also, NFC Bluetooth Handover between PC Linux and Android will be described. The section Cloud Campus System explains our developed cloud system with some kinds of open source software. In the section Registration system in smart tablet, we explain the software to register the cloud campus system by using NFC. In the section Conclusion, we describe the operation rules of the registration system to the cloud service system such as privacy protection.

In order to be more student-centered and supportive of students with different needs, the project of Smart University (Mitchell et al.2003) is underway in some universities.

Recently, the attendance management system (AMS) with RFID technology has been developed as a part of Smart University (Mitchell et al.2003), which develops the educational infrastructure using high technologies, such as ICT. However, the reader/writer for Felica is too expensive to build the AMS. Because the developing system with Felica requires the software library provided by the specified maker. The library is prohibited the use under the opensource software. Furthermore, the reader/writer is set at each lecture room and the teacher cannot witness the student’s authentication of the ID card, so that, we may meet that one of friends instead of ther person in question can answer the roll call for an absentee.

NFC reader/writer technology is equipped with the smartphone or smart tablet such as Google Nexus. The smart tablet can easily be carried around, so the student must be checked the attendance in the teacher’s presence. Therefore, the records in the system are correctly and the student becomes an earnest student to attend the lecture for real.

Figure4 shows the system overview of our developed AMS system and the system of educational affair’s section. The Nexus part is used to call the roll by teachers. The educational affairs section collects the data related to the absentee by connecting the Nexus to PC after the lecture. The data communication is via Bluetooth connection or the directed connection with microUSB. If the IC card reader/writer is equipped with the PC, data is transmitted automatically after the Peer-to-Peer connection with NFC authentication.

NFC bluetooth handover between PC linux and android

This section explains our developed connection software to realize the NFC Bluetooth Handover between PC Linux and Android smart tablet. For the developing an application software to read/write NFC tag, the NFC library corresponded to the kind of chip in the hardware of NFC reader/writer should be required.

We developed the application driver by using ‘Linux-NFC (Ortiz et al.2012)’ or ‘Romuald Conty2009’ because the chip in the ordinary NFC reader/writer is ‘pn533’ in Japan, called ‘RC-S370’. In the case, the use of ‘libnfc’ is an effective developing method. However, the production of RC-S370 has been stopped. Therefore, only next-generation model RC-S380 is available to develop the application driver for the NFC reader/writer. The libnfc for RC-S380 cannot be supplied the NFC library as open source software. As a result, only the nfcpy2014 leads to success in data communication between PC Linux and Android smart tablet as shown in Figure9 (See Additional file1).

The NFC Bluetooth Handover is one of methods of data communication between some devices and the method can enable the data communication without pairing of Bluetooth. The method exchanges the Bluetooth Mac address of two devices, both as close to the device each other. After the exchange of Mac address, actual data communication to the corresponded device will be executed. The advantage in the method can be used only the communication between NFC and Bluetooth. Of course, a more secure communication such as encrypted data will be required. However, the distance between the PC and the smart tablet in the system is limited within the small-scale size. Therefore, the reasons for no-encrypted data communication are as follows. 1) NFC communication is performed by an user’s explicit action such as the touch of cards. 2)The decryption for the encrypted data with the different encryption library will occur the error. Especially, the encryption/decryption system should use the same encryption algorithm, however, the library of Linux Java is not same as that of Android system. For the encryption of different devices, we should adjust some parameters of encryption algorithm in each device. The encrypted data communication has been succeeded, but the time till the end of file takes a long time.

The teachers can receive the list of student data from PC-Linux and vice versa by using the developed data communication system between PC Linux and Android tablet. Therefore, we can find the students with high absent rate and/or find the continuance of the absent students. If a student absents on every Thursday, he/she works at a part-time job on that day. If the other students absent at any first period classes, they oversleep every day. We can perceive the appearance of student who tends to be absent from school. He/she has the possibility for the school refusal.

The relationship between student and university may be important factor for the problem of Chronic absenteeism, truancy and academic failure. According to the change of social environment, it is required that university needs to be more student-centered and support of students with different demands. The NFC Attendance Management System can check the student’s attendance. We are going to mining the characteristics patterns of student behaviors from the collected data. Moreover, the teacher can form a relationship between teacher and student via the system.

A cloud system is categorized into the three following types:

The “Service” in SaaS is “the function of software”. That is, the service offers not the software itself but a function in the network. On the contrary, the term ‘SOA (Service Oriented Architecture)’ is a software architecture design on the construction of a grand scale computer system and the service in SOA means “the software parts for realizing service due to business model cases”. That is, it is a business component in the client-server model computers. Many developments in the field of computer architectures become to provide a great benefit in the computing forms and the data transmission speed in the Internet becomes faster for the last decade. Moreover, both virtualization and tools for the use of big data are realized in our daily life. All the advances in the environment has made it easier to serve and manage their own “Service infrastructure”. Therefore, because SaaS is related to PaaS and IaaS, we can summarize the cloud computing as a large category.

In order to use the cloud service, we use the Google cloud platform. However, the server must preserve the intellectual property of the document/contents and the privacy of the users to construct a Safe and Trusted ICT environment. Therefore, our team aims to separate the own documents and contents. To enable a user to comfortably utilize the server, we develop the authentication of the services for the single sign-on (SSO). The SSO provides a property of access control of multiple related, but independent software system.

Social network service

Recently we are familiar with the communication on the Social Network Service (SNS), which provides us various abilities under the construction of social community such as to communicate with friends, to talk a chat, to share photos, organize the event, and so on.

We constructed the Social Network Service system by using open source software called “OpenPNE (Kazu-fuku2011)”. It provides a full set of functions necessary for SNS including mobile phone. Figure10(a) shows the user’s connection list and time line.

However, the OpenPNE does not have the functions to sync and share the files from all devices such as computers, smartphone, and so on. Especially, the OpenPNE cannot allow to access the specified files to the specified users.

Many kinds of university courses that are open to the general public are planned every year. The university course gives an educational opportunity provided by colleges and universities to people who are not enrolled as regular students. In order to participate in the extention lectures of our university, the persons wishing to participate make request by a postal application. However, it is a state of being troublesome. In case of the receiving the application, the staff must pigeonhole the applications.

Figure11 shows the interface to register the NFC tag in the smartphone/smart tablet such as Nexus. If the user has Android smartphone/smart tablet with NFC reader/writer, he/she registers the personal information and the own NFC tag into the Cloud Campus System. The email address is the already prepared own Google ID. The password is not required to enter, because the password to authenticate the Google ID is used in the Cloud Campus System. The user logins in the SNS service and make a registration for the corresponding lecture, by using the event function of OpenPNE. The user presents the extension lecture and touches the registered NFC tag at the registration desk.

The relationship between student and university may be important factor for the problem of Chronic absenteeism, truancy and academic failure. According to the change of social environment, it is required that the teacher of university considers that the effective method of more student-centered and supportive of students with different needs.

In this paper, we developed AMS for university with NFC on Nexus. In this system, the teacher can form a relationship between teacher and student, because the teacher can recognize the faces displayed on Nexus when the student touch the ID card to it. Although many investigations are not implemented, absentees at almost classes decreased. We consider that the student has the consciousness of being observed.

Moreover, we have developed the connection software to realize the NFC Bluetooth Handover between PC Linux and Nexus. The software can transfer any encrypted database files between PC Linux and Nexus. So, the attendance situation collected from different Nexus is merged into a SQLite file and then, early discovery for chronic non-attenders are extracted in educational affairs section.
