The objective of this fall 2008 ELEC 301 class project is to hide a binary message within a piece of audio without damaging perceptual sound quality. This Module is an abstract summary of the work done to meet that objective.

The purpose of this activity is to introduce students to the concept of binary coding as a language and its practical applications in digital and communication systems. This project is intended to give students a deeper appreciation for communication systems and an understanding of how binary symbols are used to transmit information.

Topics on the engineering of computer software and hardware systems: techniques for controlling complexity; strong modularity using client-server design, virtual memory, and threads; networks; atomicity and coordination of parallel activities; recovery and reliability; privacy, security, and encryption; and impact of computer systems on society. Case studies of working systems and readings from the current literature provide comparisons and contrasts. Two design projects. Students engage in extensive written communication exercises. Enrollment may be limited.

This Module details the conclusions reached about three different encoding and decoding algorithms used to hide digital data in audio for the fall 2008 ELEC 301 class project. For small amounts of noise, all three algorithms work effectively to encode binary data in many types of music.

This module details the algorithm used to decode digital data hidden in audio as part of the fall 2008 ELEC 301 class project.

This module details the primary three algorithms explored for encoding digital data in audio as part of the fall 2008 ELEC 301 class project.

The interaction between law, policy, and technology as they relate to the evolving controversies over control of the Internet. Topics include: intellectual property and copyright control, privacy and government surveillance, and freedom of expression and content control.

This course considers the interaction between law, policy, and technology as they relate to the evolving controversies over control of the Internet. In addition, there will be an in-depth treatment of privacy and the notion of "transparency" -- regulations and technologies that govern the use of information, as well as access to information. Topics explored will include: Legal Background for Regulation of the Internet Fourth Amendment Law and Electronic Surveillance Profiling, Data Mining, and the U.S. PATRIOT Act Technologies for Anonymity and Transparency, The Policy-Aware Web

This Module details the ideas that could be used to extend or improve the fall 2008 ELEC 301 class project on information hiding and audio watermarking.

This course focuses on the fundamentals of information security that are used in protecting both the information present in computer storage as well as information traveling over computer networks. Upon successful completion of this course, the student will be able to: explain the challenges and scope of information security; explain such basic security concepts as confidentiality, integrity, and availability, which are used frequently in the field of information security; explain the importance of cryptographic algorithms used in information security in the context of the overall information technology (IT) industry; identify and explain symmetric algorithms for encryption-based security of information; identify and explain public key-based asymmetric algorithms for encryption-based security of information; describe the access control mechanism used for user authentication and authorization; describe Secure Sockets Layer (SSL) as a common solution enabling security of many applications, including all Internet-based commerce; describe securing Internet Protocol (IP) communications by using Internet Protocol Security (IPSec); explain the importance of physical security and discuss ways to improve physical security of an enterprise; explain the use of such security tools as firewalls and intrusion prevention systems; explain malicious software issues, such as those brought forth by software-based viruses and worms; explain common software security issues, such as buffer overflow; describe the basic process of risk assessment in the context of overall IT security management.

This is a simple activity to visualize a communication system. In order to do this the students encode, decode, transmit, receive and store messages. They will use a code sheet and flashlight for this process. They will also maintain a storage sheet from which they can retrieve information as and when it is required.

This module details the "attacks" used to test the three methods of encryption (frequency, phase, and echo) and how they responded to deliberate external attempts to break them. This is a continuation of the fall 2008 ELEC 301 class project.

This module details the testing methods used to compare the three methods of encryption (frequency, phase, and echo) studied as part of the fall 2008 ELEC 301 class project.

This course is a student-presented seminar in combinatorics, graph theory, and discrete mathematics in general. Instruction and practice in written and oral communication is emphasized, with participants reading and presenting papers from recent mathematics literature and writing a final paper in a related topic.

This Module details the practical applications of information hiding and watermarking audio as studied in the fall 2008 ELEC 301 class project.

This course will expose you to the basic fundamentals of the Internet and Web protocols, the different architectures that Web-related applications use, and the programming languages that enable the development of Web applications. The student will also cover matters of security and reliability in the development of web applications via the use of transport encryption and authentication. Upon completion of this course, students will be able to: demonstrate an understanding of the Internet and Web Protocols; demonstrate an understanding of Client-Server Architecture; explain how Web Software works; demonstrate an understanding of Hypertext Markup Language (HTML) Programming concepts; demonstrate an understanding of basic JavaScript, AJAX, and Java Server Pages (JSP); demonstrate an understanding of Web Security and Encryption.
