Definitions

  • the present invention relates to a method for establishing whether or not a first person who has identified himself for entrance to a confined area with the aid of a magnetic card inserted in a card reader shall be granted free passage to said confined area through a door, gate or like entrance.
  • the present invention is based on the understanding that the card reader is capable of identifying a code or a numerical sequence significant to the magnetic card concerned, and that the code is compared with a plurality of pre-stored codes through the agency of electric and/or electronic circuits intended herefor.
  • buttons bank which is connected to a central processing unit by means of which a person requiring to enter a confined area through a door served by the locking or latching system can identify himself as being an authorized person who is entitled to enter said area.
  • the button bank co-acts with a code generating device which, in turn, co-acts with a central processing unit, the arrangement being such that the insertion into the button bank of a specific code common to all authorized users and/or a particular significant code allotted to a particular person results in the activation of circuits incorporated in the central processing unit so as to produce therein a signal for activating or deactivating a door latching circuit when the code inserted is accepted.
  • a card reader which co-acts with a central processing unit of the aforesaid kind can be said to be known from European Patent Application No 84114432.2, Publication Number 0 146 812.
  • a more qualified technical problem in this regard is one of -creating, with the aid of simple means, conditions which enable the magnetic card used to comprise a card which is also intended for purposes other than for gaining access to a confined space.
  • a further technical problem in conjunction herewith resides in the provision of simple means which with regard to identification of the person desiring access to the confined space or area, will afford a greater degree of security than that normally afforded by a code lock system having identification codes programmed therein.
  • a more pronounced technical problem with regard to high security levels, or if desired higher security levels, resides in the provision of conditions which enable access to be obtained to a confined space or area with the aid of a conventional credit card, bankers card, cashpoint card, petrol or gasoline credit card, or like card.
  • Another technical problem is one of providing conditions which enable the apparatus and devices required for high security level identification to be readily installed.
  • Still a further technical problem in the present regard is one of creating, with the aid of simple means, conditions which will enable a large number of individual codes to be stored, in practice scarcely in excess of five hundred codes, corresponding to the number of persons to which access to a confined space can be permitted subsequent to identification, thereby to render the system sufficiently flexible.
  • Another technical problem resides in the provision of conditions which enable the complex codes which refer to a large number of mutually different magnetic cards and such cards as those which present a visible, embossed code to be used directly and to be stored in the system in their entirety, or in all events to a sufficiently large extent, without detracting from the demand for a high level of security.
  • a further technical problem resides in the provision of conditions which enable a code significant to the person concerned to be inserted readily into the system with the aid of a magnetic card intended for purposes other than that of providing access to a confined space or area, subsequent to the system being coded for programming by a person who is reponsible for monitoring the persons, and their magnetic cards, desiring entry to the confined space or area.
  • each person who is given possession of a magnetic card of the aforesaid kind, in which a code is stored and which is programmed in the manner aforedescribed, is also given an individual code which can be committed to memory, such that the individual code, which shall apply simultaneously and in combination with the code incorporated in the card, is also stored in the central processing unit at the time of entering the code on the card into the memory of said unit.
  • Another qualified technical problem is one of creating, with the aid of simple means, conditions by means of which the individual code can be formed, said code preferably being in relation to the code found on the magnetic card.
  • a further qualified technical problem is one of perceiving that a code which is intended to inhibit or block codes stored in the system should contain or consist of a conversion factor used to form the personal code.
  • a card reader which is arranged to evaluate a code significant to the magnetic card and to compare said code with one or more codes present among a multiplicity of pre-stored codes, with the aid of electric and/or electronic circuits intended herefor.
  • the invention is based on the qualification that a signal for activating or deactivating a circuit for latching or locking the door, gate or like entrance will be generated only when the code incorporated in the magnetic card presented by the person concerned coincides with one or more of said pre-stored codes, therewith affording free passage to said person.
  • a second person responsible for monitoring the persons, preferably all persons, desiring access to the confined space, actuates means provided in the electric and/or electronic circuit for enabling the significant code incorporated in the magnetic card to be stored among pre-stored codes, subsequent to the card being read in the card reader.
  • this second person then confirms the identity of the first person and a magnetic card belonging to said first person and intended for principal purposes other than obtaining access to the confined space.
  • the card reader Upon insertion of the magnet card belonging to the first person into a card reader, the card reader senses the significant code on the card in question.
  • This arrangement enables the whole of the significant code on the magnetic card held by the first person to be stored as an additional code among the codes previously stored in the memory core.
  • the signal for activating or deactivating the circuit for latching or locking the door, gate or like entrance is -made active solely for a limited time duration, e.g. a time duration between one and thirty seconds.
  • the identification code it also lies within the scope of the invention to form the memorizable personal code (the identification code) by adding a conversion number or conversion factor to a group of numbers in a numerical series significant to the magnetic card and the code incorporated therein.
  • This conversion number or factor may be, to advantage, the whole of, or part of, an inhibition code.
  • a method according to the present invention reside in the possibilities of enabling a person desiring entry to a confined space or area to provide the requisite proof of his identification, authorizing his entry into said space or area, with the aid of a magnetic card which is intended for purposes other than that of attaining access to the confined space or area, so that a magnetic card previously issued to the person in question can be assigned and obtains a use additional to that for which it was initially intended.
  • FIG. 1 there is illustrated a door 1 which can be locked and opened with the aid of lock 3, which is electrically operable by means of a striking plate 2. Electric current can be supplied to the striking plate through a two-wire cable or lead 4, the wires 4a and 4b of which are connected to a current supply source not shown.
  • a button bank 6 which is connected to the cable 4 by means of two wires.
  • the button bank 6 incorporates a conventional code generating device, which generates a code corresponding to a predetermined number of selected symbols (digits). This code is transmitted to a central processing unit, in which the code is processed in a conventional manner. If the code received by the central processing unit is found to be valid, the unit produces a high power carrier signal which is transmitted over the cable 4,to activate the striking plate 2 of the door 1.
  • the button bank 6 and a central processing unit having the requisite number of storage facilities are combined to form a single assembly, as described in more detail hereinafter.
  • the card reader may be mounted, to advantage, on the outer casing of the button bank 6.
  • a card reader 7 which is arranged to cooperate with the button bank and said central processing unit.
  • the present invention affords the possibility of establishing whether or not a first person who has identified himself as being a person entitled to enter a confined space or area (behind the door 1), by inserting a personal magnetic card into a card reader 7, shall be granted free passage to said confined space through the door 1.
  • FIG. 2 illustrates diagrammatically the manner in which the method according to the invention is carried into effect.
  • the card reader 7 is constructed to evaluate, in a known manner, a code significant to the magnetic card in question, which code may also comprise a digital sequence or some other discernible characteristic peculiar to said card.
  • the codes sensed by the card reader 7 are transmitted, via electric and/or electronic circuits, to a card receiver 10, and are compared in a comparitor 11 with an assortment of codes pre-stored in a storage memory 12.
  • a second person namely a person responsible for monitoring the persons requiring entry to the confined space or area, activates, through the button bank 6, means 16 which are incorporated in the electric and/or electronic circuit 15 and which activate a circuit 17 so as to enable the significant code of a magnetic card subsequently sensed in the reader to be stored in the aforesaid memory via the circuit 17, among the pre-stored codes in the memory 12.
  • the invention is based on the assumption that the second person visibly identifies the first person and makes certain that the magnetic card possessed by the first person and intended for major purposes other than obtaining entry to a confined space or area really belongs to said first person and carries an identifiable code which can be sensed in the card reader. Subsequent to the second person establishing the identity of the first person in the aforesaid manner, the magnetic card belonging to the first person is inserted into the card reader 7, which senses the significant code on the card and stores the code in the memory 12, through the circuits 10 and 17.
  • the significant code is therewith stored as an additional code among the pre-stored codes in the memory 12, so that subsequent sensing of the magnetic card concerned in the card reader 7 affords free entry to the confined space or area, subsequent to being compared in the comparitor 11 and activation of the striking plate 2.
  • the invention also enables a higher security level to be achieved with the aid of simple means, by requiring the person desiring entry to the confined space or area to insert into the circuits, through the button bank 6, a personal identification code memorized by the person concerned, in addition to presenting to the card reader a magnetic card having incorporated therein a code which coincides with one or more of the codes stored in the memory, before granting said person free access to the confined space or area.
  • This personal code is detected in a circuit 18, which is connected to the memory 12.
  • the striking plate 2 is not activated until it has been established that the code on the magnetic card coincides with one or more of the pre-stored codes, and that the identification code inserted into the circuits coincides with a coresponding identification code stored in the memory 12.
  • the identification code for storage in the memory 12 can be inserted in substantially the same manner as the code found on the magnetic card.
  • a change-over clock 19 is provided for establishing the periods of time over which a lower security level can be accepted,during which period all that is required to obtain access is the magnetic card, and those time periods over which a higher security level is required, i.e. a security level in which both magnetic card and the aforesaid identification code must be used and found valid before entry is granted.
  • the signal for deactivating the latching circuit 2 for the door, gate or like entrance is caused to occur, via a circuit 20, over a limited time duration, for example a time duration between one and thirty seconds, depending upon the location of the card reader and the orientation of the door, gate or like entrance, thereby preventing unauthorized persons from passing into the confined space or area without permission from the person activating the circuits for entrance to said confined space.
  • Figure 3 illustrates in more detail a circuit diagram over the arrangement illustrated in Figure 2.
  • Figure 3 illustrates an electric circuit diagram of a button bank 6 and a central processing unit with the requisite memories incorporated in the button bank.
  • button bank is referenced 6 and the connections to a card reader 7 are referenced 7a.
  • the reference 21 illustrates an electric contact incorporated in the processing unit for programming the code applicable for inserting and storing codes belonging to magnetic cards. This code shall be memorized by the aforementioned second person.
  • the reference 27 illustrates an electric contact incorporated in the processing unit for inhibiting one or more stored codes corresponding to mutually different magnetic cards. This code shall also be memorized by the aforesaid second person, although the secrecy requirement is less stringent in this case.
  • Figure 3 also shows the manner in which a processor 23 is connected up, this processor being connected to a memory address register 24, a programme memory 25 and a data memory 26.
  • the reference 27 identifies a decoder and reference 28 identifies an automatic re-start circuit.
  • the reference 29 identifies the conductor or wire connected to the clock 19, a signal on this conductor indicating a security level in which a correct code entered via the code reader is sufficient to obtain free access.
  • the electric contact 21 is activated and a six digit code is inserted via the button bank 6. This code may be 11 22 33.
  • the electric contact 22 is activated and a six digit code is inserted via the button bank 6. This code may be 44 55 66.
  • the personal code may be formed, for example, by adding the aforesaid four selected digits to the last four digits in the inhibition code.
  • the personal code may be formed as follows
  • Tr R personal code need not be inserted via the button bank 6,but can be calculated in the processor of the central unit and stored in the data memory 26.
  • the first person can be informed of which digits in the magnetic-card code,when this code is visible constitute the digits applicable to the personal code, while selecting a simple inhibition code at the same time, for example "00 00 01", the personal code comprising an addition of these number.
