Fоllоwing the deаth оf а hospitаlized child, the nurse tells his mother, “We will miss him so much.” The best interpretation of this statement by the nurse is:
The fоllоwing questiоns аre аbout dаtabase security. A de-identified and anonymized database D has been made public. Each quasi-identifier (QID) in D appears in at least n rows or tuples. Furthermore, no two tuples with a common QID have the same value for the sensitive element in D. Assume n=10 and the total number of tuples in D is 1,000,000. If D satisfies k-anonymity and l-diversity requirements, what are the values of k and l for D? (2+2 pts.) Will increasing k always increase l in this system? Explain your answer. (2 pts.) How will the utility and privacy provided by D change when l is increased? (4 pts.) MacOS and iOS send information from our devices to Apple that could have an impact on our privacy. According to some reports, for information collected by iOS, Apple claims to provide differential privacy guarantees with epsilon = 14. There are approximately 300 million people in the United States. Assume a certain sensitive property that defines a person of interest is true only for 100 people (this could be people who suffer from a very rare disease). Thus, when no information is shared with Apple about any user, the random chance that Alice is a person of interest is 1/3000000. Assume that the information collected by iOS could potentially be leveraged with available auxiliary information for a targeted user to answer the question if a certain user, i.e., Alice, is a person of interest. With differential privacy when epsilon = 14, what is the probability that Alice is likely a person of interest when she chooses to share her information with Apple? First, write the formula that relates the probabilities of an inference when Alice chooses to share or not share her information. After this, estimate the probability of the inference attack for the given value of epsilon. You can assume that e14 is approximately 1.2 million. (2+3 pts.) Do you think epsilon = 14 is reasonable? If not, epsilon could be decreased. How will user privacy and utility for Apple change when we reduce epsilon from 14 to 10? Explain your answer. (2+1+1 pts.) Answer the following questions for a multi-level secure database that uses the model discussed in the SeaView system. True or false: Elements in a tuple can have different access classes even when the tuple access class is the same as the access class of the tuple’s primary key element. Explain your answer. (2 pts.) Assume null values in an instance of a multi-level relation have the access class of the primary key of the tuple in which they appear. All instances of a multi-level relation have the same tuple access class for a certain tuple t with a given primary key value k. True or false: Different elements in t can have different access classes. Explain your answer. (5 pts.) In a certain system, TS or top secret is the highest clearance level. A TS user executes an update transaction on a multi-level secure database system that supports the SeaView model of poly-instantiation. Which of the following are possible outcomes of this update transaction: (i) no poly-instantiation occurs, (ii) visible poly-instantiation occurs, and(iii) invisible poly-instantiation occurs. Briefly explain your answers. (2+2+2 pts.) Since SeaView supports multi-level security, covert channels could be a possibility. If you believe covert channels can be established in SeaView, describe a storage covert channel that a secret user can create to transmit secret information to a user cleared at a lower access level. (3 pts.)
