Technical challenges for identification in mobile environments

This report describes some main technical challenges and requirements for identification of individuals in mobile (i.e. non-stationary) environments as e.g. required by the "European Mobile Identification Interoperability Group" (MOBIDIG). It is intended to support relevant stakeholders as law enforcement agencies or immigration offices, active in the area of identification of individuals in mobile environments. It offers some guidance for future technical work at the MOBIDIG to be respected in their work plan. Furthermore, it may be used as a first orientation for the general future work for identification in mobile environments using digital or electronically stored data. After the introduction and some background of MOBIDIG and its policy context, the document presents the intention, main objectives and some information about the scope of work of the group. The following proposals, suggestions and recommendations presented are explicitly focusing on technology. Organizational and procedural issues are out of focus of this document and need to be addressed separately in further documents.
