Abstract: The present invention relates to a method comprising the steps of sending random or pseudo-random information to a display unit of an electronic device, inputting information to a data entry unit of an electronic device by a user using random or pseudo-random information in accordance with a predetermined rule, checking whether the information entered matches to information which is previously stored in a memory unit, and authenticating of the user in case that the information entered by the user matches to the information which is previously registered in the memory.

Abstract: The invention relates to a power generator. The power generator comprises a vessel provided with a heat exchanging unit for alternatingly heating and cooling an organic based working fluid contained in the interior of the vessel during operation of the power generator. Further, the power generator comprises a mechanical unit associated with the vessel and provided with a reciprocating moving element that moves responsive to the heating and cooling process. The heat exchanging unit is arranged for heating the working fluid from below an evaporation temperature and for cooling the working fluid from above the evaporation temperature. Further, the power generator comprises a pressure transferring structure for transferring a pressure exerted by gas in the vessel towards the mechanical unit for driving the reciprocating moving element.

Abstract: A card reading machine includes a card reader for reading data on a magnetic card and a device for preventing reading of the data on the magnetic card by illegal card reading devices operatively associated with the card reading machine. The device for preventing may include an oscillator, a driver circuit and a coil for generating electromagnetic signals similar to data on a card. A method for preventing reading of data on a magnetic card by in illegal card reader in operative association with an apparatus having a card reader intended to read the data on the magnetic card includes producing a signal ruining the data collected by the illegal card reader. The apparatus having a card reader may include an insertion slot in which case the method may further include producing the signal near the insertion slot.

Abstract: The invention relates to a self service terminal, such as an Automated Teller Machine, comprising a front panel provided with a card insertion slot for inserting a magnetic card therethrough, wherein, during insertion through the insertion slot, a magnetic stripe on the card induces a card data flux into a stripe data reading zone. The terminal also comprises an anti-skimming unit for generating a jamming field so as to jam a magnetic recording unit of an illegal card reader installed near or in the card insertion slot of the front panel. The anti-skimming unit includes a first magnetic field source and at least one further magnetic field source, each source inducing a electro-magnetic field in a slot region including the card insertion slot, such that the jamming field in the stripe date reading zone deviates from the jamming field outside the stripe data reading zone.
