The PIS comprises i) a passenger information terminal for communicating information to users when located in the public compartment; and ii) a first electronic identification device configured to receive an electronic identification from an operator when located in the restricted compartment and to register the electronic identification with the PIS as a registered electronic identification; and iii) an interfacing system comprising inputting means for inputting information into the PIS. A second electronic identification device is configured to receive an electronic identification from a user of the interfacing system. The PIS is arranged to authorize the inputting of information when the electronic identification from the user matches the registered electronic identification. ## Claims ### Claim 1 A passenger information system for a public transport vehicle comprising one or more public compartment accessible by users of the transport vehicle and comprising a restricted compartment accessible by an operator of the transport vehicle to which users of the transport vehicle are not allowed access; said passenger information system comprising: one or more passenger information terminal for communicating information to the users when located in the one or more public compartment; and a first electronic identification device configured to exchange an electronic identification with the operator when the operator is located in the restricted compartment and to register the exchanged electronic identification with the passenger information system as a registered electronic identification; and an interfacing system, said interfacing system comprising: one or more inputting means for inputting information into the passenger information system; and a second electronic identification device configured to receive an electronic identification for accessing the inputting means; wherein the passenger information system is further arranged to authorize the inputting of information via said inputting means when the electronic identification received by the second electronic identification device matches the registered electronic identification. ### Claim 2 (depends on 1) The passenger information system according to claim 1 wherein the public transport vehicle is a train, a metro, a bus or a tram. ### Claim 3 (depends on 1) The passenger information system according to claim 1 wherein the interfacing system further comprises a mechanical lock unlockable by a skeleton key. ### Claim 4 (depends on 1) The passenger information system according to claim 1 wherein the first and second electronic identification device comprises at least one of the group of: a keyboard, a cardreader, a wireless card reader, a Radio-Frequency Identification, RFID, reader, a Near Field Communication, NFC, reader; and a finger-print reader. ### Claim 5 (depends on 1) The passenger information system according to claim 1 wherein the inputting means comprises at least one of the group of: a network interface for connecting a communication device to the passenger information system; a microphone; a telephone handset; a keyboard; and a touch screen. ### Claim 6 (depends on 1) The passenger information system according to claim 1 wherein the restricted compartment is a driver's compartment. ### Claim 7 (depends on 1) The passenger information system according to claim 1 further configured to automatically erase all registered electronic identifications each time the passenger information system is rebooted. ### Claim 8 (depends on 1) The passenger information system according to claim 1 further arranged to perform the authorization temporarily. ### Claim 9 (depends on 8) The passenger information system according to claim 8 further arranged to de-authorize the inputting of information via said inputting means after the inputting of information. ### Claim 10 (depends on 1) A public transportation vehicle comprising a passenger information system according to claim 1. ### Claim 11 A computer-implemented method for protecting access to a passenger information system installed in a public transport vehicle comprising the following steps: exchanging by a first electronic identification device a first electronic identification with an operator when the operator is located in a restricted compartment of the public transport vehicle; and registering the exchanged first electronic identification in a data store for storing registered electronic identifications; and receiving by a second electronic identification device a second electronic identification for accessing an inputting means for inputting information into the passenger information system; and wherein the second electronic identification device and the inputting means are part of an interfacing system; authorizing inputting information into the passenger information system via the inputting means when the second electronic identification received by the second electronic identification device matches one of the registered electronic identifications in the data store. ### Claim 12 (depends on 11) A data processing system comprising means for carrying out the method of claim 11. ### Claim 13 (depends on 11) A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out the method of claim 11. ### Claim 14 A passenger information system for a public transport vehicle comprising one or more public compartment accessible by users of the transport vehicle and comprising a restricted compartment accessible by an operator of the transport vehicle to which users of the transport vehicle are not allowed access; said passenger information system comprising: one or more passenger information terminal for communicating information to the users when located in the one or more public compartment; and a first electronic identification device configured to exchange an electronic identification with the operator when located in the restricted compartment and to register the electronic identification with the passenger information system as a registered electronic identification; and an interfacing system comprising one or more inputting means for inputting information into the passenger information system; and comprising a second electronic identification device configured to receive an electronic identification from a user of the interfacing system; wherein the passenger information system is arranged to authorize the inputting of information via said inputting means when the electronic identification from the user matches the registered electronic identification and to de-authorize the inputting of information via said inputting means after the inputting of information.
