This chapter discusses the interplay between the European personal data protection regime and two specific Google services, Interest Based Advertising and Google Street View. The chapter assesses first the applicability of the Data Protection Directive, then jurisdictional issues, the principles relating to data quality, whether there is a legitimate purpose for data processing, and lastly the transparency principle in connection with the rights of the data subject. The conclusion is that not all aspects of the services are easy to reconcile with the Directive’s requirements.
