Personal Information Ethics
How is personal information analysed using computers?
-
Computers play a critical role in analysing personal information, particularly in areas such as healthcare, where medical records are involved
-
The process involves data gathering, storage, and analysis, where various technologies and techniques are implemented
Data mining
-
This involves extracting patterns from large data sets
-
In the healthcare context, it can help in predicting disease trends and identifying at-risk demographics
Machine learning
-
Machine learning algorithms can predict patient outcomes, assess risks, and personalize patient treatment plans based on past data
Artificial intelligence
-
AI is used to process large amounts of data and make predictions or recommendations
-
E.g. AI can analyse medical images to detect diseases or anomalies
Impact of analysing personal information
-
As computers become increasingly pivotal in managing and analysing personal information, such as medical records, there arise consequential moral, social, ethical, and cultural implications
-
These implications call for careful consideration and the establishment of comprehensive frameworks and guidelines to safeguard individuals’ rights and privacy
Moral implications
Consent & autonomy
-
From a moral standpoint, obtaining informed consent from individuals before gathering, storing, and analysing their personal information is crucial
-
Consent respects the autonomy of individuals to control information about themselves
Equity
-
There is a moral obligation to ensure that the benefits derived from analysing personal information, such as improved healthcare outcomes, are distributed equitably and do not disproportionately favour specific groups
Social implications
Privacy
-
Personal information, particularly health data, is sensitive
-
The use of computers to manage this data increases the risk of privacy breaches with significant social implications
Digital divide
-
The digital divide refers to the disparity between individuals who have access to technology and those who do not
-
The use of computers in managing health data may inadvertently exclude those who lack access to digital technology, leading to social inequity
Ethical implications
Data security
-
Given the sensitive nature of personal information, there is an ethical obligation to protect this data from breaches, theft, or misuse
Transparency & accountability
-
Organisations must be transparent about how personal information is used and be held accountable for any misuse of the data
-
This necessitates robust auditing mechanisms
Cultural implications
Cultural sensitivity
-
The use of personal information should respect cultural norms and practices
-
E.g. some cultures have specific beliefs about health and privacy that must be respected when gathering and analysing their health data
Representation
-
There is a risk that certain cultural groups may be underrepresented in data sets, leading to biased outcomes
-
Efforts must be made to ensure fair representation of all cultural groups in the data-gathering process
Case Study
AI screening breast cancer images
-
A Swedish study suggests that artificial intelligence (AI) can effectively read breast cancer screening images
-
The research, led by Lund University, found that AI could detect cancer at a rate similar to two radiologists
-
The study involved over 80,000 women, with AI-supported screening identifying cancer in 244 women, compared to 203 identified through standard screening
-
Significantly, AI did not increase the rate of “false positives”
-
Experts believe AI could help address radiologist shortages and improve efficiency in breast cancer screening
-
However, more research is needed to understand its potential and cost-effectiveness fully
