Which of the following is a potential privacy risk of Electronic Health Records (EHRs) (digital patient files used in hospitals)?

Which of the following is the biggest challenge in anonymizing health data (removing personal identifiers while keeping research useful)?

1

Which anonymization method provides the strongest mathematical privacy guarantee (ensures patient data cannot be reconstructed)?

A hospital releases anonymized patient records for research. The dataset includes patients' age, city, and rare disease history. A researcher cross-references this data with publicly available voter registration records and successfully identifies a patient. Which anonymization principle was most likely not configured properly?

שאלה #169069

		K-Anonymity – The dataset had too few individuals in each group, making identification easy.
		L-Diversity – The dataset included sensitive attributes that were too uniform within each group.
		T-Closeness – The distribution of sensitive attributes (disease type) was too different from the general population.
		Differential Privacy – Noise was not properly added to the dataset.

If each group (age, city, disease) contains only one or very few individuals, it becomes possible to uniquely identify someone by cross-referencing with other available data. Proper K-Anonymity would require ensuring that each unique combination of quasi-identifiers (age, city) appears in at least K instances to prevent reidentification.

A hospital releases anonymized patient records containing age, city, and a rare genetic condition. The dataset groups patients by age ranges (e.g., 30-40, 40-50), but in one city, only a single person aged 45 has the rare disease. A journalist cross-references voter registration records and easily identifies the patient. What anonymization principle was violated?

		K-Anonymity – The group size was too small, allowing unique identification.
		L-Diversity – The dataset lacked diversity in sensitive attributes.
		T-Closeness – The distribution of sensitive attributes was mismatched.
		Differential Privacy – Insufficient noise was added to prevent linkage attacks.

A pharmaceutical company shares a dataset with hospitals for research. The dataset is anonymized, grouping patients by age, city, and disease. However, in one city, all patients within a specific age range (50-60) have the same disease: HIV. A health insurance company analyzing this data determines that anyone aged 50-60 from that city is likely HIV-positive. Which anonymization principle was violated?

שאלה #169071

		K-Anonymity – The dataset contained too few individuals in each group.
		L-Diversity – The dataset lacked variety in the sensitive attribute (disease).
		T-Closeness – The distribution of sensitive attributes did not match the general population.
		Differential Privacy – The dataset did not include enough noise.

A government agency releases an anonymized dataset on heart disease. The dataset ensures each group contains multiple people (K-Anonymity) and different diseases (L-Diversity). However, in one small town, the percentage of patients with heart disease in the dataset is 80%, whereas in the general population, it is only 10%. A researcher analyzing the data realizes that most residents in that town likely have heart disease. What anonymization principle was violated?

שאלה #169072

		K-Anonymity – The group size was too small.
		L-Diversity – There was not enough variation in diseases.
		T-Closeness – The disease distribution in the dataset was too different from reality.
		Differential Privacy – The dataset failed to prevent reidentification with added noise.

Which of the following best describes a major risk when transmitting medical data between healthcare providers?

שאלה #169073

		Loss of patient trust due to redundant data entries
		Security vulnerabilities that could lead to data breaches
		Increased time required for manual data entry by doctors
		High electricity consumption by hospital data centers

Which of the following best describes the ‘fee-for-service’ (FFS) model in healthcare?

1

שאלה #169074

		Doctors receive a fixed salary regardless of patient visits
		Doctors are reimbursed based on the number of services performed
		Healthcare providers are paid based on patient health outcomes
		A fixed amount is paid per patient, regardless of services used

A hospital using a fee-for-service (FFS) model might have which of the following financial incentives?

1

שאלה #169075

		To minimize the number of procedures performed on patients
		To prioritize preventive care over reactive care
		To increase the number of billable procedures performed
		To focus on holistic patient health rather than specific treatments

מיין לפי

		Economic abuse by insurance companies.
		Hospitals losing financial incentives.
		Patients gaining access to their own records.
		Increased efficiency of healthcare delivery.

		Removing patient names and ID numbers is sufficient.
		Rare diseases + demographics can still reidentify patients.
		Anonymization makes research impossible.
		AI automatically anonymizes patient data.
