At week 11, we have learned a very interesting but serious topic, Privacy. In fact in this day and time, since the electronic technology has developed so fast and has overwhelmingly dominated people's lifestyle, personal information seemed would never be well secured. Some approaches may have directly or indirectly acquired people's privacy and might be distributed to anywhere in exchange for money or other goodwill. For example, the buyer loyalty plans, surveys, credit info, cookies... The objectives of those may not be just as simple as so-called "for your convenience" but also for other purposes that may infringe your rights. After all the above mentioned ones are optional, you can choose not to take them at all. Some other ways, however, require your personal info since they are not allowed to be kept private, such as hospital of birth, date of birth, gender, etc. These info can help identify a person quite thoroughly. Even in our campus, our UT mail has been contracted out to Microsoft. Our personal data may be shared or may appear on some certain lists. It also claimed that this may not infringe our rights. But really? Anyway, for us, we need to realize the importance of protecting our privacy. What we could do include many like, creating reliable passwords, updating security systems, encrypting.. Always be careful!
Besides privacy, we've also learned new things from Dr. Racket. The concepts of "flatten" and "depth" seemed confusing at first. But after watching the videos a couple of times and hearing the professor's explanations, I finally figured them out and did quite well in the quiz.
In summary, this is my favorite lecture of this semester. The topic of privacy is appealing to me.
