Obtaining data concerning the property of the suspected person or suspected course of actions aiming at recognising, preventing, detecting and prosecuting offences is of essential significance. With reference to information covered by bank secrecy of vital importance are the kind of actions in the course o f which information is to be obtained, they may be obtained in the course of operation and examination actions or procedural actions. Postulated solution to this problem should involve the creation of a central register of bank accounts with changes in law enabling the prosecutor access to information included in this base on the same terms, which are currently binding, when this information is required directly from the bank or the provision of online information exchange within the frames of the existing and secure system dedicated to processing information constituting bank secrecy, such as the OGNIVO system of the National Clearing House (KIR S.A.).
