In view of the development of jurisprudence on informed consent surrounding patient-doctor relationship, Paternalistic Model has become outdated and replaced by autonomy-based Informed Consent. However, the Act on a Health Sector Database enacted in Iceland still has evoked global criticisms from scientists, sociologists, philosophers and privacy-activists. UK Biobank has adopted a different approach. UK Biobank seeks to introduce a formal procedure, which provides a sufficient elaboration and subsequently acquires consent from potential participants so that participants' autonomy for their genetic information can be protected. As global attention has turned to the ethical, legal and social implications (ELSI) of biobank, informed consent has played a key role in these controversial issues. It is propounded in this paper: (1) sampling of individuals' biological samples, such as blood, tissue and urine based on individual informed consents in UK Biobank, group genetic information of particular races might be gathered without group informed consent, (2) the relationship among participans in UK Biobank should be clarified, (3) once participants agree to join UK Biobank, their biological samples and genetic information should be regarded as contributions to the public and be placed in public domain as shared information, and (4) adopting the concept of informed choice, providing additional choices to the participants.
