The present volume contains the proceedings of the 1st International Workshop on TEchnical and LEgal aspects of data pRIvacy and SEcurity (TELERISE 2015), held in conjunction with the 37th International Conference on Software Engineering (ICSE 2015) in Florence, Italy, on May 18, 2015. The workshop provides a forum for researchers and engineers, in academia and industry, to foster an exchange of research results, experiences, and products in the area of privacy-preserving and secure data management, both from a technical and legal perspective. The ultimate goal is to conceive new trends and ideas on designing, implementing, and evaluating solutions for privacy-preserving information sharing, with an eye to the cross-relations between ICT and regulatory aspects of data management.
