Broad Band & Economy According to the study released by Connected Nation, A 7 percent increase in broadband adoption would: –create 2.4 million jobs across the U.S; –save $6.4 billion in vehicle mileage –U.S. residents would save 3.8 billion hours a year by conducting transactions online, at a cost-savings of $35.2 billion, according to the study. – U.S. is behind other nations – FCC chairman: Broadband access should be universal-- Wednesday, November 25, 2009 – bin/article.cgi?f=/n/a/2009/11/25/financial/f051435S42.DTL

B2C System Model

Channel Conflict For example, a manufacturing company may have a large, established dealer network. The channel conflict exists, when the companies tries to open another channel, such as an online store where customers can purchase goods directly from the company. This may alienate existing dealers, since they may feel that they are bypassed. Web presence without online store –Anthon Berg Chocolate

E-Learning Electronic learning or eLearning is a general term used to refer to computer-enhanced learning. Many higher education, for-profit institutions, now offer on-line classes. The Sloan report, based on a poll of academic leaders, says that students generally appear to be at least as satisfied with their on-line classes as they are with traditional ones. Example: GIS online course – p

Internet Security Authenticity: Is the sender/receiver of a message who they claim to be? Privacy: Are the contents of a message secret and only known to the sender and receiver? Integrity: Have the contents of a message been modified during transmission? Nonrepudiation: Can the sender of a message deny that they actually sent the message?

Encryption (Cryptography) Plain text: the original message in human- readable form. Ciphertext:the encrypted message Encryption algorithm: the mathematical formula used to encrypt the plain text. Key: the secret key used to encrypt and decrypt a message.

Public Key Encryption Uses two different keys: a public and a private key. Receiver’s public key must be delivered in advance. Sender uses receiver’s public key to encrypt the message and receiver uses private key to decrypt the message (Sender can be sure the receiver is the true receiver) Example: –RSA (Rivest, Shamir, and Adelman) algorithm with 512-bit to 1024-bit key. Note: Although the two keys are mathematically related, deriving one from the other is “computationally infeasible”.

Certificate A certificate is a digital document issued by a trusted third-party certificate authority (CA). A certificate contains records such as a serial number, user’s name, owner’s public key, name of CA, etc. Example of CA: VeriSign, U.S. Postal Service.

Online Transaction Security Protocol Secure Sockets Layer (SSL) –Developed by Netscape –SSL implements public key technology using the RSA algorithm and digital certificate to authenticate the server in a transaction and protect private information.

Tech heavyweights join OpenID Foundation board IBM, Google, Microsoft, Yahoo and VeriSign have joined the board of the OpenID Foundation, which puts consumers a little closer to being able to use a single sign-on when they surf the Web. It is simpler: People no longer have to remember multiple passwords or re-enter their personal information every time they visit a new site. It is also more secure because it protects against certain types of online attacks.
