Content ownership and liability issues of genomic data
Computer Engineering Department
We consider a scenario that includes an individual sharing his sequential data like genomic data, location data etc. with a service provider. In this scenario, if his data is shared without his consent, the individual wants to determine the service provider that is responsible for this leakage. We achieve these functionalities by inserting a unique watermark into the data for each sharing. If there is a data leakage, we can find the source of the leakage by checking the watermark inside the leaked data. Watermarking is basically changing some part of the data but there is a direct proportion between protection of the data and the utility loss. The amount of the utility loss may be crucial for some type of the data like genomic data. Thus, we minimize the utility loss while we try to reach a level of protection.
