Coding can involve legal pitfalls for developers' employers or hirers, and even for developers personally. For example, the proposed EU General Data Protection Regulation would introduce requirements for data protection "by design and by default", including security by design/default, and the concept of "privacy engineering" is rapidly gaining traction. After discussing the role of law and contract terms (including international/global aspects), this session will outline some main points to watch out for in relation to intellectual property rights to software and data "ownership". Then it will move on to its main focus, namely key legal issues for developers regarding data protection/privacy, particularly in the context of websites, mobile apps, cloud and IoT. However, many compliance issues can also give rise to business opportunities. Some free resources for technology law advice/information will also be discussed.
