How we use your information

The primary aim of this research is to assess human variation of the dorsal knuckle crease and the impact of digital flexion on their appearance in digital images. The aim of Knuckle Down ID is the development of a large ground truth database of hand images with which we conduct this research.

If you choose to provide personal data in response to any of our questions, you should understand that we will hold and process that information in the dataset we generate from the survey responses.

We will retain the raw data from the submission responses (12 JPEG images, associated meta data, survey answers, consent and newsletter preferences) until the end of Academic Year 2031 on the LRCFS internal repository, when it will be deleted. We will retain our anonymous analysis and reporting.

If consent for the 12 JPEG images and survey answers to be made accessible to other researchers via controlled access is given, the associated meta data will be wiped and further anonymisation will be carried out with the removal of your unique identification number. After the 30.06.2022 we will retain the data within the controlled access database on the grounds of Article 17, S.3(d) of GDPR as changes to the controlled access dataset would make the work of researchers impossible or seriously impair the research process.

If you are interested in getting news and updates from the Knuckle Down ID Team regarding the research you can choose to receive a newsletter. The University of Dundee will require some of your personal data to provide this service to you. The information you provide will be used to enable the University to administer the sending of the newsletter. Each communication you receive will include instructions of how to stop receiving the newsletter, once you have made a request to withdraw your details and to stop receiving the newsletter the University will act upon your withdrawal request.

You are under no obligation to complete this project.
