asks for a blood sample from a participant to see if there is a relationship between something which can be measured in blood and a person's health. In both cases, the ideal outcome is that any participant can join the study and neither the researcher nor the study design nor the publication of the study results would ever identify any participant in the study. Thus, the privacy rights of these individuals can be preserved. Privacy for medical research participants is protected by several procedures such as

laws, and transparency in how patient data is accumulated and analyzed. People decide to participate in research for any number of different reasons, such as a personal interest, a desire to promote research which benefits their community, or for other reasons. Various guidelines for human subject research protect study participants who choose to participate in research, and the international consensus is that the rights of people who participate in studies are best protected when the study participant can trust that researchers will not connect the identities of study participants with their input into the study. Many study participants have experienced problems when their privacy was not upheld after participating in research. Sometimes privacy is not kept because of insufficient study protection, but also sometimes it is because of unanticipated problems with the study design which inadvertently compromise privacy. The privacy of research participants is typically protected by the research organizer, but the

Information privacy

Researchers publish data that they get from participants. To preserve participants' privacy, the data goes through a process to de-identify it. The goal of such a process would be to remove protected health information which could be used to connect a study participant to their contribution to a research project so that the participants will not suffer from
data re-identification Data re-identification or de-anonymization is the practice of matching anonymous data (also known as de-identified data) with publicly available information, or auxiliary data, in order to discover the individual to which the data belong. This is ...

Privacy attacks

A privacy attack is the exploitation of an opportunity for someone to identify a study participant based on public research data. The way that this might work is that researchers collect data, including confidential identifying data, from study participants. This produces an identified dataset. Before the data is sent for research processing, it is "de-identified", which means that personally identifying data is removed from the dataset. Ideally, this means that the dataset alone could not be used to identify a participant. In some cases, the researchers simply misjudge the information in a de-identified dataset and actually it is identifying, or perhaps the advent of new technology makes the data identifying. In other cases, the published de-identified data can be cross-referenced with other data sets, and by finding matches between an identified dataset and the de-identified data set, participants in the de-identified set may be revealed. This is particularly the case with medical research data because traditional data anonymization techniques designed for numerical data are not as effective for the nonnumerical data contained in medical data, such as rare diagnoses and personalized treatments. Thus, in cases like medical research data that contain unique nonnumerical data, only removing identifying numerical features, such as age and social security number, may not be enough to mitigate privacy attacks.


Risk mitigation

The ideal situation from the research perspective is the free sharing of data. Since privacy for research participants is a priority, though, various proposals for protecting participants have been made for different purposes. Replacing the real data with
synthetic data Synthetic data is information that's artificially generated rather than produced by real-world events. Typically created using algorithms, synthetic data can be deployed to validate mathematical models and to train machine learning models. Data g ...
allows the researchers to show data which gives a conclusion equivalent to the one drawn by the researchers, but the data may have problems such as being unfit for repurposing for other research. Other strategies include "noise addition" by making random value changes or "data swapping" by exchanging values across entries. Still another approach is to separate the identifiable variables in the data from the rest, aggregate the identifiable variables and reattach them with the rest of the data. This principle has been used successfully in creating maps of diabetes in Australia http://onlinelibrary.wiley.com/doi/10.1111/1753-6405.12262/full and the United Kingdom using confidential General Practice clinic data.

data and personally-identifying data. For many reasons, biobank research has created new controversies, perspectives, and challenges for satisfying the rights of student participants and the needs of the researchers to access resources for their work. One problem is that if even a small percentage of genetic information is available, that information can be used to uniquely identify the individual from which it came. Studies have shown that a determination of whether an individual participated in a study can be made even from reporting of
aggregate data Aggregate data is high-level data which is acquired by combining individual-level data. For instance, the output of an industry is an aggregate of the firms’ individual outputs within that industry. Aggregate data are applied in statistics, da ...

When research participants have their identities revealed they may face various problems. Concerns include facing

Respondents in the United States have expressed a desire to have their research data to be restricted from access by law enforcement agencies and would want to prevent a connection between study participation and legal consequences of the same.

. In the case of genomic studies on families, genetic screening may reveal that paternity is different from what had been supposed. For no particular reason, some people may find that if their private information becomes disclosed because of research participation, they may feel invaded and find the entire system distasteful. An Australian study investigating the violence, bullying, and harassment towards LGBTIQ people revealed that some of the participants, who were all members of the LGBTIQ community, had been subjected to levels of violence that would constitute a crime. However, the participants were reluctant to report their victimization to the police. This meant that the researchers were placed in a position where they could report a crime to the police. However, ethical practices meant that they were obliged to respect the privacy and wishes of the participants and so they could not do so.
