%P 173-180 %D 2015 %B VII Congreso Iberoamericano de Telemática (CITA 2015) %X Despite that privacy requirements are becoming mandatory in many circumstances, and privacy-enhancing technologies are more and more readily available, system designers are facing a lack of guidance to choose the most appropriate solutions to protect the privacy of the system users in each situation. This paper introduces a pattern language —that is, a structured collection of interrelated, reusable solutions— for privacy-enhancing design. We present the structural model of our patterns (techniques) and introduce their use within usual analysis and design activities, with a special emphasis on the relation between patterns and the privacy requirements they fulfil. %L upm41939 %A Yod Samuel Martín García %A José María del Álamo Ramiro %A Juan Carlos Yelmo Garcia %I Telecomunicacion %T Toward a pattern language for privacy enhancing design techniques %C Popayán, Colombia %K Design patterns, Pattern language, Privacy by Design, Privacy-enhancing design, Privacy requirements operationalization
