Privacy Dataset for Context-Dependent Photo Sharing


This is a dataset for research on privacy protection in context-dependent photo sharing, in our paper titled “Context-Dependent Privacy-Aware Photo Sharing based on Machine Learning”. The dataset was created through a user study on on 20 subjects, containing 12’216 personalized context-dependent sharing decisions for 1’018 images. The dataset can be helpful for related research of privacy protection or prediction in photo or information sharing, particularly in a context-dependent scenario. More information about the paper can be found in the paper ( or For privacy issue, we cannot release the images directly. Instead, all annotated information of those images, context information and users’ sharing decisions are provided in the dataset.
