Data Mining - Concepts and Techniques.

The objective of this paper is to give a comprehensive introduction to applied cryptography with an engineer or computer scientist in mind. The emphasis is on the knowledge needed to create practical systems which supports integrity, confidentiality, or authenticity. Topics covered includes an introduction to the concepts in cryptography, attacks against cryptographic systems, key use and handling, random bit generation, encryption modes, and message authentication codes. Recommendations on algorithms and further reading is given in the end of the paper. This paper should make the reader able to build, understand and evaluate system descriptions and designs based on the cryptographic components described in the paper.

Thinking is as important as learning. It is one of important and effective learning approaches by recording and reflecting student's own learning attitude and learning performance and referring to others' learning portfolio daily. Although many of students know this approach, but seldom of them put this approach into action owing to the problem of preserving content of reflection and learning portfolio. In this paper, a networked learning reflection mechanism based on blog service is presented. Students can make their learning reflection and view others' with ease. An experiment was conducted at an Institute of Technology upon system completion. The experimental results show that there is a positive correlation between students' learning performance and attitude of learning reflection. It reveals that students who have better learning performance tend to make more reflection on their learning. More than 80% of students express this mechanism has positive affection on their learning.

The message complexity of decentralized commit protocols is studied. It is shown that O(kNN/sup 1/k/) messages are necessary if only k rounds of message interchanges are allowed. It is also shown that O(Nln N) is a message lower bound for any decentralized commit protocol. A class of decentralized commit protocols that need O(kNN/sup 1/k/) messages and use k rounds of message interchanges is proposed. If k=ln N, then a decentralized commit protocol that needs O(Nln N) messages only is obtained. The communication scheme is also used to derive some decentralized consensus protocols. >

Although blockchain technology was first introduced through Bitcoin, extending its usage to non-financial applications, such as managing academic records, is a new mission for recent research to balance the needs for increasing data privacy and the regular interaction among students and universities. In this paper, a design for a blockchain-based system, namely UniChain, for managing Electronic Academic Records (EARs) is proposed. UniChain is designed to improve the current management systems as it provides interoperable, secure, and effective access to EARs by students, universities, and other third parties, while keeping the students’ privacy. UniChain employs timed-based smart contracts for governing transactions and controlling access to EARs. It adopts advanced encryption techniques for providing further security. This work proposes a new incentive mechanism that leverages the degree of universities regarding their efforts on maintaining academic records and creating new blocks. Extensive experiments were conducted to evaluate the UniChain performance, and the results indicate the efficiency of the proposal in handling a large dataset at low latency.
