Digital forensic method used in interoperability framework for information systems used on EU level in area of migration and border management

Over the past years, great effort was directed to make the various information systems interoperable, as the lack of interoperability was recognized as a major obstacle to progress on the general  digitalization  processes. Aiming to be able to exchange data and share information so that authorities and responsible officials have the information they need, when and where they need it.  Globally the interoperability framework is a commonly agreed approach to the delivery of public services in an interoperable manner, by defining basic interoperability guidelines in the form of common principles, models and recommendations. It represents the ability of information systems to exchange data and enable the sharing of information on efficient way. Implementation of interoperability framework is challenged specially regarding large IT systems on EU level using and developing in area of border management. In it biometric data has significant role as one of containing components. In this paper main components and current status of development will be presented, including those searching portal, common biometric system, common identity data repository and multiple identity detector. Following this approach,  use of a shared biometric matching service, as digital forensic method,  has goal to  allow users to perform more efficiently search and cross-match biometric data. Furthermore, a common identity repository will enable easy access to biographical information, so person can be more reliably identified and with a multiple identity detector it will be possible to  detect multiple identities.
