    WO 2013/114364 PCT/IL2013/050084 1 SAFE CARD FIELD OF THE INVENTION 5 The present invention relates to smart cards. BACKGROUND OF THE INVENTION 10 This invention relates to credit cards. More particularly, this invention relates to systems and methods for protecting against credit card fraud and abuse. Billions of dollars are lost annually to credit card fraud. Particularly, credit card numbers 15 are copied and used without permission, for example by theft of the credit card, and unlawful copying by a salesperson. Copying may take many forms. A thief may, for example, catch a glimpse of an actual credit card and copy the number by writing the number on a piece of paper. Alternatively, a thief may intercept a digital signal representative of the credit card number and utilize such a digital signal at a later time. It 20 is therefore desirable to provide systems and methods that completely eliminate the possibility for such types of credit card fraud. Traditional credit cards that employ magnetic stripes are deficient because the magnetic stripe is highly susceptible to wear and magnetic interference. Particularly, the magnetic 25 stripe can be worn down physically or rewritten/erased by magnetic interference. It is therefore desirable to provide a robust credit card that can withstand wear and is not susceptible to interference. Furthermore, the magnetic stripe still ultimately provides data that might be intercepted and abused.
    WO 2013/114364 PCT/IL2013/050084 2 One objective is to provide a smart card that generates credit card numbers that are exceedingly difficult to intercept. Another objective is to provide a smart card wherein intercepted credit card numbers change too fast to allow abuse of the card. 5 SUMMARY OF THE INVENTION According to one aspect, a safe card is provided, comprising: at least one card sensor capable of generating at least one card input signal representing at 10 least one biometric identifier; a card input converter configured to convert the at least one card input signal into a first number; a card microprocessor; a clock; 15 at least one card computer memory comprising: a preprogrammed card lookup table of second numbers, wherein each of the second numbers is uniquely associated with a specific time of the clock; preprogrammed instructions for the card microprocessor to automatically generate, at a specific time of the clock, a third number comprising a combination of the first 20 number and one of the second numbers associated with the specific time of the clock, and a card signal output means configured to convert the third number into at least one card output signal representing the third number. 25 Said at least one card computer memory may be ROM.

With specific reference now to the drawings in 5 detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of the preferred embodiments of the present invention only, and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the invention. In this regard, no attempt is made to show structural details of the invention in more detail than is 10 necessary for a fundamental understanding of the invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the invention may be embodied in practice. In the drawings: 15 Figure 1 depicts a safe card embodiment. Figure 2 depicts a system for operating a safe card. 20 DETAILED DESCRIPTION Figure 1 schematically depicts some features of one embodiment of a safe card 100. The safe card 100 is for example an improved credit card. 25 Each card 10 is individually dispensed to a user. The card 10 comprises a computer 12 (processor and memory that can be incorporated together or not) that processes data pertaining to biometric identifiers of the user, as well as other data singular to the card at any selected time, as will further be explained below. The embodiment 10 further 30 comprises a digital display 14 as output meansand a keypad 16 as input means for manual WO 2013/114364 PCT/IL2013/050084 9 entrance of personal secret identification number (PIN), as an example. The input keys 20 can be represented by numbers, alphabetical or any other representation. The card 10 further comprises a battery 18. The display 14 is actually composed of a number of cells 15 that are each configured to display one digit of a number related to the PIN and/ or a 5 biometric identifying feature of the user, as well as another number related to or derived from the aforementioned singular data stored in the card 10. Figure 2 schematically illustrates a system 100 that comprises multiple safe cards 110 available for different users, as well as safe card readers 120 and a service provider 10 computer system 130. The safe cards 110 actively or passively convey a signal 112 representing the combined secret data and biometric identifier of the user to a safe card reader 120, for example a barcode and/or QR reader in a shop or a reader of an ATM machine, and the safe card reader 120 conveys its own signal 114 to the service provider system 130 that has stored data that is matched with the data received therein to decide 15 whether to authorize service to the user or not. The information of the safe card can be conveyed to the card reader digitally or analogically through a signal or by manual operation through a computer by which the user inputs the information to the system. Any card reader using any technology can be used without limiting the scope of the present invention. 20 Typically, the service provider manufactures the safe card and installs at least some data into the memory as well; the service provider data, however, may be data that is installed in all of the manufactured safe cards and is not singular to a given card but rather is the same in all of the cards at that time. Such data may be the base for operations performed 25 on the singular data. The singular data may be installed by another system, thereby allowing the service provider (such as a card wiring system of a credit card company) to quickly manufacture the cards without major changes to the production process compared to manufacture of commercially available cards. 30 According to one aspect, a plurality of safe cards is provided.
    WO 2013/114364 PCT/IL2013/050084 10 Each safe card comprises: a card housing; at least one card sensor on the card housing, the card sensor capable of generating at least one card input signal representing at least 5 one biometric identifier of a user; a card input converter in the card housing, the card converter configured to convert the at least one card input signal into a first number; a card microprocessor in the card housing; a first clock; 10 at least one card computer memory in the card housing, the card computer memory comprising: a preprogrammed card lookup table of numbers, wherein each time of the first clock is uniquely associated with a second number derived from the card table of numbers; 15 preprogrammed instructions for the card microprocessor to automatically: generate, at a specific time of the first clock, a third number comprising a combination of the first number and a second number associated with the specific time, each safe card having a third number at the specific time that is different from other safe 20 cards in the plurality of safe cards; card signal output means on the card housing, the card signal output means configured to convert the third number into at least one card output signal representing the third number. 25 The card housing is preferably the credit card plastic, a cell-phone or any other housing that incorporates the components of the safe card. The card may be used for access to personal bank account, drawing money out of an ATM, unlocking a computer, PDA, celluar phone, door, appliance, industrial process 30 system, vehicle, virtual or real social systems or organizations, for example.
    WO 2013/114364 PCT/IL2013/050084 11 The plurality of safe cards are operated with a system that further comprises safe card readers, each comprising: a card reader housing; at least one card reader sensor on the card reader housing, the card 5 reader sensor capable of reading the card output signal; a card reader input converter in the card housing, the card reader input converter configured to convert the at least one card reader input signal into a fourth number, and a service provider computer system comprising: 10 a second clock; a service provider microprocessor; at least one service provider computer memory comprising: preprogrammed service provider lookup tables of fifth numbers, wherein each fifth number in the service provider tables 15 is associated with a time of the second clock; preprogrammed instructions for the service provider microprocessor to automatically: at the specific time generate at least one sixth number derived from the fifth numbers associated with the specific time, and compare the sixth numbers to the fourth number, 20 so as to allow service to the user when a sixth number is identical to the fourth number. Numbers generated for output in each safe card are unique to the same safe card, relative to all the other safe cards interactive with the service provider computer system, at any 25 given time. Typically, these unique numbers have been carefully matched with a store of numbers in the service provider computer system, before the cards were manufactured, so that at any time the user uses the safe card, there is a match between the unique generated numbers of the card and one of the numbers generated by the service provider computer system at the same time. 30 WO 2013/114364 PCT/IL2013/050084 12 The term "time" is to be broadly construed as relating to either a specific time or a period of time such as 5 minutes. The time may also be relative to a reference time, for example the time of the manufacture of the cards. The clocks may be the respective processor of the card and/or the service provider computer system. 5 Typically, the service provider computer system generates tables of numbers for all of the safe cards at any given time; alternatively, data identifying the user may be conveyed to the service provider computer system, that triggers generating a sixth number for the user that should match the fourth number. 10 After said given time, the third numbers change. Typically, second numbers are sequentially drawn from the tables in the memory of the card. A similar or identical process may occur in the service provider computer system, i.e. a number ascribed to the user may be combined with a PIN of the user and the resultant combination compared to 15 the number provided by the card or the card reader. Note that whereas typically the service provider computer system has stored therein a PIN of the user, or at least the numbers stored therein contain digits of the PIN, the cards may not store therein the PINs, so that the cards cannot be used without the user 20 providing the PIN or a biometric identifier to the card. Such cards may not include a keypad. However, in some cards the PIN may be stored; in which case the card is typically locked until the user manually enters the PIN to the card. It will occur that despite the uniqueness of the numbers generated in each card, two cards 25 or more might simultaneously generate the same third number by the card. This quandary may be solved by the service provider computer system or other system carefully checking all existent and functional cards, at all of the programmed times, to ensure there is no duplicity of numbers at any such time.
    WO 2013/114364 PCT/IL2013/050084 13 According to another aspect, a safe card system comprising the safe cards, safe card readers and service provider computer system is provided. Further features, embodiments and limitations may serve to increase the security of the 5 cards/system and/or make them more particularly suitable for intended uses. In some embodiments the card computer memories of the safe cards are ROM only, to protect the cards from tampering that might alter the stored data. The numbers may be hardwired in the cards, Preferably, the processor and memory are 10 part of a microcontroller. The card output signals in some embodiments comprise a barcode and / or QR and at least a portion of the card reader sensors comprise barcode and/or QR readers, to allow the cards to be used at shops etc. In particular, the card output signal means on at least a 15 portion of the safe cards with the barcode/QR generators exclude alphanumeric character displayers and USBs or other output means that might allow an unauthorized user to learn how to abuse the card, although the periodically changing third number renders unlawful successful use of the card exceedingly difficult if not impossible. The output means is for example a Bluetooth. The output signal is for example an SMS. 20 The excluded alphanumeric character displayers comprise digital display screens and printers. Such exclusion in principle renders the card even safer for use, however a user may prefer to see the numbers generated by the card, and perhaps copy the numbers or print them to review previous uses of the card. 25 The service provider computer system may periodically or upon request for the user provide reports of the credit card numbers of the card, in the form of a table containing use time and matching number, for example, and the user may compare the numbers in the report to numbers directly obtained from the card. 30 WO 2013/114364 PCT/IL2013/050084 14 Some embodiment therefore have the card signal output means selected from a group comprising: at least one display screen, a printer, USB and combinations thereof. In some embodiments of the safe cards: 5 the card computer memory in at least a portion of the safe cards further comprises a lookup table of arrays each with a set of rearrangement parameters, each time of the clock being uniquely associated with a set of rearrangement parameters, and the preprogrammed instructions for the card microprocessor further 10 comprise instructions to automatically rearrange the digits in the first number at the specific time according to the a set of rearrangement parameters associated with the specific time. The rearrangement is another encryption step. 15 In some embodiments of the safe cards: the card computer memory further comprises a lookup table of arrays with operand parameters, time of the clock being uniquely associated with an operand parameters array, and the preprogrammed instructions for the card microprocessor further 20 comprise instructions to automatically calculate the third number based on the operand parameters of an operand parameters array associated with the specific time. The operands may be mathematical operations applied in sequence or in parallel to a 25 single number or digit, for example the number 100 may be drawn as a second number, which is first squared to 10000 and then subtracted from 10000 to result in the number 9900 that can be output to a screen as is or in a further altered form, for example digits may be removed or added, to fill the screen cells together with digits of the first number.
    WO 2013/114364 PCT/IL2013/050084 15 The manipulation of the numbers may be performed by a low-level language such as Assembler, and may include shift and rotate operations. The manipulation may further comprise rearrangement of the numbers before or after the application of the operands, again on the basis of arrays storing parameters for the 5 rearrangement, each array tied to a particular time. The biometric identifiers may be selected from a group comprising: voice, retina pattern, PIN number, fingerprint, handprint, facial features, and combinations thereof. 10 At least in a portion of the safe cards the card signal output means comprises a screen, the screen may comprise a series of display cells, each cell configured to display one digit of a decimal base of the third number, and wherein: the card computer memory further comprises a lookup table of arrays each with a set of rearrangement parameters, each time of the clock being uniquely 15 associated with a set of rearrangement parameters, and the preprogrammed instructions for the card microprocessor further comprise instructions to: automatically remove digits from the second number in decimal base, at the specific time, according to a set of rearrangement parameters 20 associated with the specific time; output digits remaining in the second number after the removal to display cells according to the position of the digits in the second number decimal base; replace removed digits in the second number decimal base with 25 digits of the first number, wherein the third number is the second number decimal base with removed digits thereof replaced with the digits of the first number. The user may see on such embodiments a changing number that also periodically has 30 digits removed (leaving blank cells behind), which are filled with the digits of the first WO 2013/114364 PCT/IL2013/050084 16 number representing biometric identifier of the user. A report of the credit card numbers generated by the card will list numbers that are all containing all of the digits representing the PIN of the user, however typically the digits will not be in proximity with each other but rather scattered in the third number, thereby rendering the PIN number harder to 5 copy. In some embodiments, in at least a portion of the safe cards: the card computer memory further comprises a lookup table of arrays each with a set of operands, each time of the clock being uniquely associated with a set 10 of operands, and the preprogrammed instructions for the card microprocessor further comprise instructions to automatically calculate the second number from a number in the card table of numbers associated with the specific time, according to the set of rearrangement parameters associated with the specific time. 15 The operands are used to calculate a number based on the second number. As the second number, the operands are encoded when the card is manufactured, however the same operands may be used by all the cards at a given time, whereas the second number is unique to each card at any given time. Nevertheless, the calculation involving operations 20 on the second number contributes to the encryption of the credit card number. The cards may further comprise batteries operationally coupled to the processor. Other powering means may be used instead, such as movement-powered means. 25 The housing is selected from the housing of a credit card, a smart card, a cellular telephone, a computer (desktop, portable etc) and a PDA. The safe card readers may each further comprise a GPS configured to assign a seventh number unique to the location of the safe card reader, and the input converter is 30 configured to combine the seventh number with an eighth number assigned to the card WO 2013/114364 PCT/IL2013/050084 17 reader input signal, to generate the fourth number. Thus, a credit card number may also contain a part identified with the card reader. Such identification may be used to help prevent use by thieves of a stolen card in an area outside the geographic range where the card may be used, for example, or to limit use of the card outside the shopping area where 5 the card is used, for a certain period of time. Alternatively, at least some of the safe cards each further comprise a GPS configured to assign a seventh number unique to the location of the safe card, and the card processor is configured to combine the first, second and seventh number, to generate the third 10 number. Some of the safe cards may further comprise communication means configured to allow the clock of the safe card and the clock of the service provider computer system to synchronize their times. Such synchronization may help reduce false mismatches of the 15 credit card with the service provider due to time lags.
