- the ticket "T” defines the period of time and / or the date until which the user can use the parking space. It is therefore valid during this period of time, or until the expiry date.
- the invention proposes a method for editing a "T" ticket, as shown in FIG. 1, which comprises:
- control step “C” can take place anywhere when during the period of occupation of the parking space. This is why the "T” ticket must remain behind the windshield for the entire period of time.
- the control step “C” can also be carried out after the parking period, when managing complaints for example.
- the step of determining "EC" of the period of validity of the ticket "T” begins with a step of payment "PS" of a sum of money “SP”.
- the "PS” payment stage is followed by a “DC” definition stage for the period of validity of the "T" ticket.
- This step of defining “DC” the duration of validity of the ticket “T” consists in determining the start and end times of parking calculated as a function of the amount of money paid “SP", that is to say the parameters "IT” relating to the validity of the "T” ticket.
- the parking end time is generally equal to the time at which the user makes the payment increased by the duration of the period of time calculated according to the amount of money paid "SP".
- the step of recording "EIA” of the authentication information "IA” consists in generating authentication information "IA".
- This authentication information "IA” is determined as a function of at least one parameter "IT” relating to the validity of the ticket "T", and at least part of the authentication information "IA” is encrypted.
- the step of recording "EIA” of the authentication information "IA” comprises a step of generating "G l” of a first part "PI" of the "IA” authentication information.
- the step for generating the first part "PI” consists in encrypting at least one of the parameters "IT" relating to the validity of the ticket "T” in order to obtain a code which is simple to identify, that is to say two or three numbers or a drawing which is easily identifiable when checking the "T" ticket.
- the first part "PI” is determined from the end of parking date, or "day date”. It is possible to determine the first part "PI” by encrypting other "IT" parameters relating to the validity of the "T” ticket, such as for example the date of validity of the "T” ticket or the day when parking begins. . It is also possible to encrypt several of these pieces of information together.
- the first part "P I" is encrypted according to a key algorithm.
- the key is modified by re-programming the parking meter "HO", which can be re-programmed on site by a maintenance agent, or by downloading from the parking meter control body. when these are connected to a central station.
- This key modification step is part of an initial "INIT” step for configuring the time stamp "HO". This step occurs at the start of the process, before the start of a transaction, so several consecutive transactions can take place without the need to change the key.
- the method includes a loop corresponding to a transaction, and the start of this loop is located after the "INIT" configuration step.
- the loop also includes a final test step "TS" which corresponds to the deactivation of the parking meter "H", for example for its maintenance.
- the key Since the key is modified at times determined by the control body, it is not possible to know precisely what the value of the key will be at any given time. This complicates the task of a fraudster who could try to determine the key, for example from tickets provided by parking meters, and not use the key to print false tickets.
- the key can be changed, for example, every two weeks or after 1,000 tickets.
- a stolen "HO" parking meter can only produce titles for a maximum of fifteen days or 1000 tickets.
- the first part “P I” can also be in the form of a drawing, the shape and / or color of which are defined as a function of a parameter relating to the validity of the ticket "T".
- the periodic reprogramming of the parking meter "HO” is then the definition of the law of variation of the shape and / or the color of the first part "PI” as a function of one of the parameters "IT" relating to the validity of the "T" ticket.
- the step of recording "EIA" of the authentication information "IA” comprises a step of generation "G2" of a second part “P2" of the authentication information "IA".
- This second part “P2" is a unique identification number for the ticket "T". This identification number is an incremental number determined from the previous transaction, the generation step "G2" of the second part “P2” is then an incrementation step.
- the second part "P2" is an authorization number for the payment transaction.
- This authorization number is created when payment is made, for example, by a bank card or a GSM phone.
- the purchase transaction is authorized by a system external to the parking meter control body.
- a transaction number is then assigned so that it can be used later, in particular by banking organizations when clearing or invoicing.
- the step of recording "EIA" of the authentication information "IA” comprises a step of generating "G3" of a third part “P3" of the authentication information "IA".
- This third part “P3” consists of a “signature” of the parking meter “HO", this signature being determined from a specific signature function specific to the parking meter “HO".
- the third part “P3” is determined as a function of the first part “P I” and as a function of the second part “P2". This part "P3" inevitably ensures the validity of a ticket
- This third part "P3” makes it possible to increase the difficulty of falsifying a "T” ticket, in particular by copying the first part "PI” from a ticket already printed and by generating a second part " P2 "consistent.
- the step of recording "EIA" of the authentication information "IA” includes a last step of printing "PS2" of the authentication information "IA" on the ticket.
- the two printing steps "PS I" and “PS2" are simultaneous.
- the method also includes a control step “C” of the transaction which is in known manner, carried out by a control officer "A” who is generally a contractual police officer.
- the control step “C” includes a step “LT” for reading the information which is printed on the ticket “T", as shown in FIG. 4.
- This “LT” reading step firstly makes it possible to verify that the parking end time has not been exceeded, in which case the user would be in violation.
- the verification of the regularity of the ticket "T” is carried out by comparison of the authentication information "IA" with authentication information called reference "IR".
- the reference information "IR" is the first part “P I" of the authentication information "IA”.
- the first part "PI" of the authentication information "IA” is determined as a function of the validity date or of the date of receipt of the ticket "T", it is common to several tickets or even to all the tickets issued in the same day.
- control "C" is performed on all of the authentication information "IA”.
- the reference authentication information “IR” is then determined during a step “GR” of generation of the reference authentication information.
- This generation step “GR” of the reference authentication information “IR” can consist of taking the reference authentication information "IR” from other tickets already printed and placed inside other vehicles, or by printing a ticket from the parking meter.
- the control agent "A” may have at his disposal an electronic device for generating the reference authentication information "IR".
- This electronic device can be connected to the time stamp "HO” in order to take the coding parameters specific to the time stamp "HO", which are the signature function, the coding algorithm of the first part "PI", and the key to the coding algorithm.
- the electronic device can also include a "SPC" storage element in which all of the coding parameters of each parking meter are recorded.
- the reference authentication information "IR” is then generated by the electronic device after entering the parameters "IT" relating to the validity of the ticket "T", which are printed on the ticket “T". Entry can be manual by means of a keyboard, or automatic by means of an optical reader. The generation of the reference authentication information "IR” is then carried out according to the same steps as the generation of the authentication information "IA”.
- the step of generating the reference authentication information "GR” is followed by a step of comparing "CMP" between the authentication information "IA” and the reference authentication information "IR” .
- the system comprises an element for editing a "T" ticket which is generally a parking meter "HO”, and a control element for the "T” ticket which is so general a control officer "A”, ie a contract police officer.
- the time stamp "HO" includes elements for dialogue with the user such as for example a display element 10, control buttons 12, in particular for validation and / or cancellation of the operation for editing a ticket “T", means of payment 14 ,.
- the time stamp "HO” also includes an editing unit “CPT” of the parameters "IT” relating to the validity of the ticket "T", an editing unit of the authentication information "IA”, and a printing unit “P” of parameters "IT” relating to the validity of the ticket "T” and of the authentication information "IA”.
- the "CPT” editing unit of the "IT" parameters relating to the validity of the "T” ticket is a computer of the type belonging to the common parking meters.
- the authentication information editing unit "IA" comprises three computers "Cl", “C2” and "C3". These computers make it possible to generate the first, second and third parts "PI", "P2” and "P3" of the authentication information "IA”.
- the first computer “Cl” makes it possible to generate the first part "PI” of the authentication information "IA” by encryption of at least one of the parameters "IT” relating to the validity of the ticket "T".
- the second calculator “C2” makes it possible to generate the second part "P2" of the authentication information "IA” by generating an identification number. To generate the identification number, the second computer “C2" includes an element of calculation by incrementation from the number of the ticket edited during the previous transaction.
- the second computer "C2" is connected to an external system for authorizing the transaction. This system is used when payment is made via a bank card or a GSM phone.
- the third computer "C3” makes it possible to generate the third part "P3" of the authentication information "IA” by coding the first part “PI” of the authentication information "IA” with the second part “P2" "authentication information” IA ".
- the parking meter “HO” also includes a printing element “P" of a ticket “T".
- the printing element “P” is connected to the editing unit “CPT" of the parameters "IT” relating to the validity of the ticket “T” and to the computers "C l", “C2” and “C3” of the three parts of the authentication information "IA", the printing element "P” collects the information provided by the various computers and prints it on the ticket "T”.
- control element "A" of the ticket that is to say the contractual police officer, performs the steps of the process defined above. These steps are carried out either by agent "A" himself, or by an electronic device (not shown) which is available to him.
- FIG. 7 shows a control element "A" which is in the possession of the control officer.
- the control element “A” comprises an input unit “LIA” of the information which is published on the ticket “T", in particular of the authentication information "IA".
- the "LIA” input unit can be, for example an alphanumeric keyboard or an optical reader.
- the control element “A” also comprises a unit “CIR” for determining the reference authentication information "IR”, a comparison unit “CP” making it possible to verify the regularity of the authentication information, and a storage unit “SPC” of the coding parameters "PC".
- the "SPC” storage unit can be supplied from a central station at the start of each tour. It can also be supplied during the agent 's tour. When the supply to the storage unit
- the electronic device comprises means for interrogating the parking meter, which comprise means of communication with the parking meter "HO" such as a connection cable or a transceiver for remote communication.
- the coding parameters "PC” can also be determined from the information printed on other tickets issued by the same parking meter "HO".
- the electronic device then comprises means for inputting this information (not shown), these input means can be the alphanumeric keyboard or the optical reader mentioned above.
- the determination unit "CIR” of the reference authentication information "IR” is then a computer which uses the coding parameters "PC” stored in the storage unit and which introduces them in the step of edition of the authentication information "EIA". This makes it possible to obtain reference authentication information "IR” which is identical to the authentication information "IA” if the ticket "T” is not falsified.
- the comparison unit “CP” compares the reference authentication information "IR” with the authentication information "IA”. If these two pieces of information are identical, the comparison unit "CP” provides an indication "R” of regularity or authenticity of the ticket. If the information is different, the comparison unit provides an indication "R” signifying that the ticket is fraudulent, and therefore liable to verbalization.
- FIG. 8 represents a ticket "T” which comes from a parking meter “HO".
- "IT" parameters relating to the validity of the "T” ticket are mentioned on the "T” ticket, such as the date “D”, the time “H” and the date “Q” of the end of parking day, as well than the amount paid "SP”.
- the ticket “T” also includes the reference number "NHO" of the parking meter “HO” which issued the ticket “T”, which in particular makes it possible to verify that the ticket “T” has not been issued by a stolen parking meter or a parking meter covering a parking area in which the "cost" of the minute of parking is cheaper.
- the ticket “T” includes authentication information "IA” allowing verification of the ticket.
- the authentication information "IA”, as described above comprises three parts “P I", “P2” and “P3”, and at least one of these parts is encrypted.
- the authentication information is printed in alphanumeric form.
- the authentication information "IA” may however be printed in whole or in part in the form of a graphic representation.
- This graphic representation is for example the first part “PI” of the authentication information "IA” which is a drawing whose shape and / or color corresponds to a parameter "IT” relating to the validity of the ticket "T”
- the authentication information "IA” is printed in part according to a printing mode understandable by the contractual police officer "A", in particular the first part " PI "which is a drawing, and the other part is printed in an understandable form by an electronic device.
- the authentication information "IA" can also be printed several times on the ticket, and according to different writing modes, thereby making any possible falsification more complex.
- the invention which has been described relates in particular to paid parking for which payment is made at the start of occupation of the parking space. However, the invention is not limited to this mode of application, and it can apply when payment is made when the user leaves the parking space.
- the instants at the end of parking and the amount paid are not defined when the "T" ticket is edited, the "T” ticket then includes information relating only to the start of parking, such as the time of receipt of the ticket "T” and the reference number "NHO" of the parking meter "HO".
- the method then has another structure (not shown), thus, the step of editing "EC" of the parameters "IT” relating to the validity of the ticket "T” is located after the step of editing "EIA" of authentication information "IA".
- authentication information "IA", in particular of the first part "PI” is made according to the time or date of the start of parking.
- control step “C” is carried out at the same time as the editing step “EC" of the characteristics relating to the transaction, these two steps can be accomplished by the same element, whether automatic or very human.
- the information medium has been described as being a printed ticket, it will be understood that the medium can be of another nature such as an electronic unit which includes a display of the liquid crystal type.
- the ticket “T” has been described as being used only during parking, the instants of start and end of parking included.
- the ticket “T” can also be used in the event of a complaint, the procedure for verifying the complaint thus comprises steps of the method described above, in particular the control step.
- a "T” ticket has been described which is used as a parking ticket.
- the invention is not limited to this use and it can be applied to many other systems using tickets to allow access to a good or a service such as amusement parks, performance halls etc. ...
- the invention therefore makes it possible to reduce the possibility of any fraud by printing a code which comprises deferent parts, and each part of which is determined differently from the others, while comprising a part which is simple to identify by an agent of control.
