Abstract: Server equipment, a system and a method are configured to receive cargo data or other data related to the transportation of cargo or to travel. Data is registered for one or more parties of the cargo, for example, on a central server. On the basis of the data, one can separate and/or link the data regarding two or more pieces of air cargo or other cargo at least part of which is transported using another means of transportation, for example transportation by road. Cargo can also refer to a passenger.

Abstract: The invention relates to a method and system for data encryption implemented in conjunction with data transmission over a communications network. According to the invention, an electronic message can be split into at least two parts that are individually forwarded to a receiver (126) via different identities (104, 106, 108, 110). The identities are, e.g., e-mail addresses, servers, subscriber connections or user identifiers. The selection of the identities, advantageously of a concealed character, can be made from a larger group of identities and may be varied on a per message, session or timed basis. Also in the receiving direction of the message it is possible to use plural different identities (114, 116, 118, 120) in the reception of a message. The received parts of the message can be identified among other traffic flow and subsequently combined with each other using key information. The arrangement disclosed herein may also be applied to data storage.

Abstract: A security system, method and apparatus for repelling computer viruses and isolating data. The security system includes sub-systems 1-3, which sub-system 1 includes an addition to anti-virus software those programs of sub-system 3 that may cause the activation of a virus. Sub-system 2 functions as a intermediate stage between sub-systems 1 and 3. In the presented method, actions are taken to activate a virus and to detect virus activation. In connection with virus activation the security system or its part can be separated from the rest of the system and thereby limit damages. When the security system is placed between two systems, it can also be used to isolate the two systems mentioned above from each other with regard to direct, real-time data transfer. The apparatus is adapted to receive a message from another apparatus and to examine the message in order to activate and to detect unknown viruses.
