• Voting Process with Blockchain Technology: Auditable Blockchain Voting System  
  by Aneta Poniszewska-Maranda, Micha? Pawlak, Jakub Guziur 
  Abstract: There exist many different electronic voting solutions and each has its own set of advantages and disadvantages. Most of the existing systems suffer from inadequate transparency and auditability. However, recently introduced blockchain technology may provide a solution to these problems. In this paper the Auditable Blockchain Voting System (ABVS) is presented. It combines existing voting approach and combines it with blockchain technology to create a supervised and remote internet voting system, which is transparent and audit capable. The paper describes the systems processes, components, model and results of initial testing.
  Keywords: e-voting; blockchain; e-voting system; audit; verification.
  
  
• Real-time Disease Detection and Analysis System using Social Media Contents  
  by Ok-Ran Jeong 
  Abstract: With the growth of social media, research that makes use of social media has become active. In particular, there are many studies that try to use social media as a sensor, because social media can generate information in real time from daily life to social issues such as disasters. Social media is also being used as a sensor for infectious disease surveillance in public health. However, there are challenges like efficient processing of large amounts of social media contents in real time and detecting disease accurately. We have developed a system that collects and processes social media contents in real time, detects and analyzes disease and visualizes the results. We build a workflow that enables real-time processing by efficiently gathering and building a model that can manage data and accurately detect disease. The system also provides intuitive and useful information to people by analyzing their opinions about diseases and visualizing the detected and analyzed information in real time. We have verified the effectiveness of the system.
  Keywords: disease analysis; disease surveillance; real-time detection; social media contents.
  
  
• Implementation and Evaluation of a Web-based Regional Culture Inheritance Support System  
  by Tomoyuki Ishida, Hengyi Li 
  Abstract: To disseminate and inherit regional culture, we have implemented a web-based regional culture inheritance support system that uses augmented reality (AR) technology based on location information. The proposed system provides its users with browsing and operating functions for digitized regional cultural content, a presentation function for this content linked with location information via a web-based geographic information system, and a superimposing function for media information using AR technology. This system offers generational inheritance of lost regional culture and information dissemination of regional culture. In addition, we implemented a simple and accessible web-based regional cultural content management system. In this study, to evaluate the effectiveness, operability, and applicability of as well as satisfaction with the proposed system, we administered a questionnaire survey to 52 subjects. High evaluations were confirmed for many items.
  Keywords: augmented reality; Web-GIS; regional culture; cultural properties; mobile application.

• Searchable Symmetric Encryption Based on the Inner Product for Cloud Storage
  by Jun Yang, Shujuan Li, Xiaodan Yan, Baihui Zhang, Baojiang Cui 
  Abstract: Searchable encryption enables the data owner to store their own data after encrypting them in the cloud. Searchable encryption also allows the client to search over the data without leaking any information about it. In this paper, we rst introduce a searchable symmetric encryption scheme based on the inner product: it is more ecient to compute the inner product of two vectors. In our construction, the parties can be Data Owners, Clients or the Cloud Server. The three parties communicate with each other through the inner product to achieve the goal that the client can search the data in the cloud without leaking any information on the data the owner stored in the cloud. We then perform a security analysis and performance evaluation, which show that our algorithm and construction are secure and ecient.
