A Design of Secure E-health Data Management System
Yvette E. Gelogo,Haeng-Kon Kim 보안공학연구지원센터(JSE) 2015 보안공학연구논문지 Vol.12 No.2
E-health is the delivery of health information, for health professionals and health consumers, through the internet. Nowadays internet-based system deployment is used in medical field due to advantages it has to offer. All the information like patient test results, diagnosis and others are stored in the database. In this paper we discuss the e-health data management system and proposed a security mechanism on how to secure the retrieving of the data in the database. Here proposed a scheme to authenticate the users and give them the right to access base on ser, role, session, permission, constraints and tasks.
Automatically Extracting Embedded Schemas from Regular Applications
Jinan Fiaidhi,Yvette E. Gelogo 인문사회과학기술융합학회 2012 예술인문사회융합멀티미디어논문지 Vol.2 No.1
A RDBMS is usually accessed using blocking drivers like JDBC/ODBC which require clients to block and wait for the result of each query they issue. An asynchronous database access mechanism would eliminate the need for such blocking and greatly improve client performance. Thread-Per-Connection and Thread Pooling are two methods currently being used to provide this asynchrony. This is inefficient since a lot of memory and computing power is spent in creating, scheduling and switching multiple threads. By these methods we cannot show how asynchronous database access can be achieved with a single thread using the Fork-Join mechanism which employs Future objects in Java. So, in this paper we propose an approach for automatically extracting embedded schemas from regular applications, e.g., written in java and automatically computing how schemas change as applications evolve. To showcase our approach, we perform a long-term schema evolution study. Our platform can be used for performing long-term, large-scale embedded schema evolution studies that are potentially beneficial to dynamic updating and schema evolution researchers.
