Database – Issue: Privacy vs Security


Explain the difference between data matching and data mining.

Data mining is the process of analyzing data from different perspectives and summarizing it into useful information and the data matching describes the efforts of a company to compare two sets of data. The data mining is for collecting the data and make inferences about it, and the data matching is compare the data collected between each other. 

Issue: security

Describe how data was lost in South Carolina tax databases.

The data wasn't lost, it was stolen by a Russian hacker. He used to hacked the financial information of all the people in the database and he sell the credit card numbers and personal information in a webpage. Depending of on the amount of money that the person have, it was the price of the information.


List the sensitive data that was lost in this security breach. How is this information going to be misused?

Credit card number
Tax returns
Debit card number
Bank number account
Social security number

Draw a conceptual map of database security breach. How is this information going to be misused?

DataBase Issue: Privacy



2.How does Target use data matching on its customers? Describe the information it uses.
It achieves all the products that the customer had been purchasing and with all that data collected they have 5 or more in common according to a pregnancy prediction.

3. Applying data mining, the article states that 25 products where identified to “predict pregnancy”. List some of these products that the article mentions.
Target noticed that woman that are waiting for a baby buy things like cocoa butter,supplements with calcium, magnesium and zinc,sanitizers, and other types like this.
4. Can you think of any other reason for a person to buy these products? Would you be offended that a company assumes that you (or a person in your family) have a condition based on the products you buy?
Sometimes I do buy this products like the cocoa butter, and supplements  and sanitizers. This products are completely normal for personal use, and if a pregnant woman buy this it doesn't mean that every woman buying this it's pregnant. I would not get offended if a company start sending coupons, but it would be awkward.
5. How did Target’s strategy changed when it found out that people were bothered about this?
They still send coupons about pregnancy and baby stuff but mixed with other coupons about different things like wine promotions, just to don't freak out the client.
6. Write a paragraph about the benefits and disadvantages for Target.
Target had create a good strategy for customers because if they send coupons to a pregnant woman when she needs them, she will definitely go buy there. That's a point for Target but if the woman is not pregnant and everything was just coincidence, many she will get offended for the “non-privacy” that the company is offering her. Also this could be in some way creepy for a woman that a company knows about their stage, and she could demand them for privacy rights.
7. What conclusion can you draw from Target’s reaction to the reporter’s plan to write this story?
Target didn't want to write this story. They think that if the customer knows that he had been “followed” and “spy” they would not want to shop there anymore, that's why they didn't want to publish this story.
8. Discuss if it is acceptable or not, that social networks collect data about their users’ interests, to enable them to sell more accurate advertising systems. (3 paragraphs)
The social network is always collecting data about their users, but sometimes it's optional for us to put it or not. One example of this is Facebook, you are not forced to publish everything, it depends on you. I personally think that is acceptable, but they have the obligation to respect the customer, if they collect data to do things like sending coupons to a pregnant woman they have to be aware that is not obvious.

The most important thing that a company should do is to protect the customer, if they don't expose the client everything would be fine because they would not feel damaged. Also a company have to give the client everything they need, in this case if a woman is pregnant and she needs pregnant stuff, the coupons would be fine for her because that's what she needs.

In conclusion I will say that it's acceptable for me to collect data of their users because it's a way to know them better and in some way please the client. Both sides are wining, the company is selling more but respecting the integrity of the client and the client is getting what he wants.

PRIVACY

2.Why is privacy important?
Privacy is important because it's your own right to be left alone.  No one have the right to public their life if they don't want to. Privacy helps the people to maintain  their autonomy and individuality from other people mouth.

3. What are the positive aspects of the police keeping a DNA database for suspects and victims?
The main positive thing is that if a suspect left DNA in the criminal scene, the police would already have the prove that he was the guilty one and the victim would be safe. And of course the justice would win.

4. What could be the negative aspects?
One negative aspect could be that someone that is innocent could be injure for something he didn't did just because they have samples of DNA.

5. Define data mining.
"Data mining, an interdisciplinary sub field of computer science, is the computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligencemachine learningstatistics, and database systems."

6. Discuss if it is acceptable or not, that social networks collect data about their users’ interests, to enable them to sell more accurate advertising systems.
 Yes it's acceptable because in order to know about the user they have to be supported with data about them, this benefits the user too because the social network can help him with the needs that he have. Of course everything has to be taken with respect for the client, and given that data should be optional.The social network is always collecting data about their users, but sometimes it's optional for us to put it or not.
