Intellectual Property Rights
Question 1
Your uncle owns a sandwhich shop. He asks you to write an inventory program for him. You are glad to help him and do not charge for the program. The program works pretty well, and you discover later that your uncle has given copies to several friends who also operate small food shops. Do you believe you should be paid for copies?
Answer:
Given that situation, I believe I should have been paid for the copies given to other shop owners. Excluding the original program I gave willingly to my uncle, I deserve a payment from those who copied copied my program for my effort, time and skill in making the system. Though it is possible that my uncle assumed that the program is for free, that assumption is only true to him and not to other shop owners. The payment that should have been given to me could be in the form of money but necessarily. It acceptably be in the form of respect and acknowledgment. My uncle and those who copied the program could have at least informed me first and asked permission from me on copying the program and should have not simply invited themselves and copy my program.
Question 2
Read articles by Esther Dyson and Lance Rose from Wired (http://www.wired.com/wired.archive/3.07/dyson/html and http://www.wired.com/wired/archive/3.02/rose.if.html). Write a short essay telling which author's view about the future of intellectual property in "digital age" are more convincing to you and why.
Answer:
Reading the article of both Esther Dyson and Lance Rose, the idea and concept of Esther Dyson about the future of intellectual property in digital age convinced me more than the view of Lance Rose did.
I agree with Esther Dyson's view that gradually the contents in the Net will become free of charge and that IT companies will make money not out of the content itself but out of the follow-up products and services to the free product initially released . Other than that, her ideas about the business strategies on the Net holds true to the present state of e-commerce. Even software developers today tend to follow the trend of giving out their softwares and yet they still make some profit out of it. Big profit actually.
Esther Dyson seems to imply also that information security in the Net cost high and even higher in the near future. Complete confidentiality, copyrights and intellectual property will take so much time, money and effort to implement and maintain and on which I agree.

1. What is the important difference between the public-key cryptography and secret-key cryptography?
The major difference between the public-key cryptography and secret-key cryptography that distinguishes one from the other is the number of keys each uses and how they use it.
The major difference between the public-key cryptography and secret-key cryptography that distinguishes one from the other is the number of keys each uses and how they use it.
In a traditional cryptography, also known as secret-key cryptography or symmetric cryptography, a single key is used by both sender and receiver to encrypt and decrypt data. The key is kept private between the two involved in the communication. Both parties should agree on what key to use before starting the communication.
On the other hand, in a modern cryptography or public-key cryptography or asymmetric cryptography, two keys are used; a public key and a private key. This cryptography is more likely to be used on a data communication wherein the sender and receiver have not yet met or there is no agreement between the two on what key is to be used. The public key is a non-secret key known by those who will be sending a message to a user. It is used by sender to encrypt the data. On the contrary, the private key is only known to a user or the one who will receive the data thus allowing him alone to decrypt and read the message which ensures data integrity.
2. What kinds of information Echelon collects?
Based on some sites concerned with Echelon activities, Echelon collects huge amount of random data and just sort out the interesting stuff or data of used to them using keywords. Since it has been said that Echelon uses these data for national security, then, maybe we could assume the Echelon collects information such as criminal records, suspected terrorists/criminal communications, politics-related data, newly discovered technology or weaponry etc.
3. Describe at least three different kinds of uses of encryption that have social value. Indicate why the are valuable.

3. Describe at least three different kinds of uses of encryption that have social value. Indicate why the are valuable.
- Encryption secures private/personal information of an individual.
- Encryption secures the authenticity and integrity of the data transmitted.
- Encryption or encrypting of data serves as a reminder for everyone involved in data transmission to be responsible and careful enough in keeping or giving out information.
The three uses of encryption mentioned above are of great value for it determines how important an encryption could be and how greatly could it affect one’s personal and social being especially to a someone in the field of information technology.
