Definitions

• the present invention relates to a control assembly for verifying the identity of individuals.
• this control unit is simple. In fact, when the individual owner of a medium introduces the latter into one of the devices and types in the manual input means in the form of a keyboard, the data of his confidential code, the processing units of the device analyzes the information read on the medium as well as the confidential code, to determine whether these are indeed correlated. In the positive hypothesis, the dial displays by a signal agreed in advance that the individual using this support is indeed the owner, in the negative hypothesis the dial displays by a signal different from the previous one that said individual is a non-user authorized.
• the invention relates more particularly to a control assembly in which the devices operate autonomously, without being connected to a terminal or to a database which by means of a storage capacity in which each information is addressed to a confidential code , would allow them to check the agreement of the two.
• a first objective of the invention consists in being able to use this control set with any identification title as support.
• the medium in this case the identification title can be kept, after control, by the holder of the device which authorizes this operation which will give access to a bank transaction or at a specific location.
• the reliability of the control can be considerably improved by adapting in the devices marking means leaving on each controlled support a trace-witness. This trace, which can be presented on a support in the form of a figurative stamp specific to a device, will provide proof that the person who used the said support was subjected to an identity check.
• a second objective of the invention is to avoid fraudulent use of the media by an unauthorized person. Indeed, the operating reliability of the control assembly mentioned above can be attacked in two main ways.
• the first is the discovery of the law of correspondence between information and the confidential code by the analysis of a significant number of these two parameters by colluding people. To resist this attack, it would therefore be necessary that the law of correspondence could only function from the confidential code to information, and in a way preventing any correlation.
• the second is a systematic investigation by scanning all the combinations of confidential code for a single piece of information, and so on for all the possible information.
• the manipulation is within the reach of a microinformatics technician.
• the values of the bit positions of the above information are distributed according to the characteristics of the confidential code. These values conventionally distributed as follows: 64-32-16-8-4-2-1, are generally assigned according to the rank occupied by the orifices from right to left. According to the invention, the distribution of these values is different from this, for example by making the rank of the value 64 depend on the number of even digits of the confidential code, that of the value of the replaced rank (here the fourth whose value is 8) is transferred to the rank provided by the number of odd digits of said code, and by moving the value of this last rank to the unoccupied one and corresponding to the number of even digits.
• the distribution of the values of the decimal positions of the confidential code (units, tens, thousands, etc.) to reduce it to a magnitude comparable to that of said information is linked to its own characteristics.
• This characteristic thus allows the value of the information not to be linked to the confidential code in a one-to-one manner.
• a third objective of the invention in relation to the two preceding ones is to allow the apparatuses a certain selection of the supports which are controlled.
• the latter include a second piece of information independent of the first and of the confidential code and intended to give indications on the holders of said media. These indications may in particular relate to the supply of the bank account of the owner of a medium (the latter may be a credit card or a bank check) or allow a category of medium to be accepted in certain devices and their owner. '' access specific locations.
• control assemblies of the invention can have multiple applications, in particular for access to particular areas such as parking lots, or even to rooms which, in a company, must be subject to increased surveillance, like computer rooms, for example.
