Description:
FIELD OF THE INVENTION 
       [0001]    This invention relates to an electronic payment system and method of the same, and more particularly to a remote payment system and method of the same. 
       BACKGROUND OF THE INVENTION 
       [0002]    It is generous to use a smart card as a payment mechanism in modern society. The principle of the smart card is emitting a radio signal by a reading device, which will activate the driver circuit inside the smart card, and the smart card will emit another radio signal to response the reading device. The transaction is carried out by the information exchanged in mentioned processes. 
         [0003]    From now on, the payment system still develops, and gradually uses a mobile phone as a carrier in the electronic payment system of contactless mode, such as the Felica system provided by Sony electric co. However, the Felica system is just attaching the smart card to the mobile phone, and there is no connection, no matter wire or wireless, between the phone and the smart card, which means the Felica system simply makes use of the habit that modern persons almost take the mobile phone everytime and everywhere, to achieve the purpose of taking the smart card in payment. Further, in order to maintain the transaction security, most of prior arts focus their attention on the security of the data transmission, but there is no concrete tactic in well preventing the smart card embezzlement when the smart card is lost or stolen. 
         [0004]    Besides, the owner of the prior smart card can not be sure if the transaction amount is exactly the same as displayed on card reader. What if the card reader request more than it displayed? The owner can not authorize the precise amount in transaction. In order to overcome the deficient, there is another improved electronic payment system provided in the prior art. The steps of the improved system includes: first, a consumer inputs the ID number and mobile phone number thereof into a merchant&#39;s inputting device; second, the inputting device transmits a password to the consumer&#39;s mobile phone; and finally, the consumer inputs the password to the inputting device to carry out the transaction. Although the improved system is safer than prior one, it works based on that the fraud has no idea about the ID number of the mobile phone owner. In some special cases, the improved system still can be embezzled by the owner&#39;s family. In addition, go through the whole steps of the forgoing systems takes a lot of time, which is inconvenient for use of gate passing, tickets buying, or shopping in a convenient store. Moreover, if the mobile phone is in weak signal area, the system will totally not work. Finally, the operation of the improved system is based on signals transmitted between the inputting device and the mobile phone, which needs corporation of several different pieces, and hence is not simple and efficient. 
         [0005]    In order to overcome the drawbacks in the prior art, A remote payment system and device of the same is provided. The particular design in the present invention not only solves the problems described above, but also is easy to be implemented. Thus, the invention has the utility for the industry.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0036]    The invention is described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for the purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed. 
         [0037]    Please refer to  FIG. 1 , which is a schematic view illustrating a remote payment system of the present invention. The remote payment  1  of the present invention includes a radio piece  10 , a controller  12  and an input &amp; password verification piece  14 , and these three pieces are connected to each other in wire or in wireless. The controller  12  not only controls the implementation of the remote payment  1  but also stores a amount of money, and the amount of the money comprise (consist?) of a currency name, such as USD, EUR, JPY or GBP, and a sum. In addition, the controller  12  has a ability of making transaction in different currencies by storing different amounts of different currencies or automatically currency exchange with card reader, which is convenient in worldwide travel. Further, the controller  12  can be replaced with a processor, or use a processor as a controller  12 . The radio piece  10  is electrically connected to the controller  12 , and the function thereof is authorizing the controller  12  to subtract an amount of a money from the sum stored in controller  12  in radio way. 
         [0038]    Please continue referring to  FIG. 1 , the input &amp; password verification piece  14  has an important role in transaction security. In special cases, the input &amp; password verification piece  14  could be a speech-recognition piece, and there is a predetermined voice stored in the speech-recognition piece. The predetermined voice could consist of a single word, a plurality of words, or a plurality of phones having a user&#39;s voice-print. For the different predetermined voices, a specific recognition zone will be defined previously. Before authorizing the charge, the user inputs a first voice to the speech-recognition piece by speaking, and then the speech-recognition piece will recognize if input speech is the amount to be paid, and verify the similarity of the first voice with the predetermined voice. If the first voice is recognized and matched to the transaction amount, and falls within the recognition zone, the charge will be allowed, which means the user passes the authorization of the remote payment system. The function of recognition zone can prevent a voice previously recorded or synthesized from passing the authorization of the remote payment system, because these so-called “false voice” described above, no matter how many times they repeat, will have the same or almost the same voice traits, which will not happen in natural human speaking. Therefore, these “false voice” will be identified by the present invention, and the charge will not be authorized. To achieve this purpose, the inputted voices in each transaction can be the predetermined voice in the next time. For example, the inputted first voices of the first to the twentieth transaction, can be the predetermined voice of the twenty-first transaction. 
         [0039]    Further, the input &amp; password verification piece  14  could be a keypad having a predetermined password therein, and the user verification can be implemented by using keypad instead of speaking. 
         [0040]    Please refer to  FIG. 2 , which is a illustrating diagram according to the first embodiment of the present invention. A speech-recognition piece  24  is configured within a first mobile phone  2   a  having a microphone  20 , and is electrically connected to the microphone  20 . Therefore a user can input the first voice to the speech-recognition piece  24  via the microphone  20 , and the first voice can be recognized/identified in the speech-recognition piece  24 . The radio piece  10  and the controller  12  are configured in a first card  1   a , and the radio piece  10  and the controller  12  are electrically connected to the speech-recognition piece  24  configured within the first mobile phone  2   a . The electrical connection may be a wire connection by metal contacts or a wireless connection within a very close distance, which makes a information could be exchanged between the speech-recognition piece  24  and the first card  1   a . The advantages of configuring the speech-recognition piece  24  within the first mobile phone  2   a , as showed in  FIG. 2 , are that the memory and the central processing unit set in the first mobile phone  2   a  can function as the speech-recognition piece  24 . In fact, the computation capability of the mobile phone getting more and more powerful and mobile phone already has microphone and memory, and hence the mobile phone can be implemented as a very sophisticated speech/speaker recognition module with microphone. Therefore, when applying the idea of present invention into the mobile phone, the only thing we need to do is to add on a speech-recognition software. Based on the mention above, the mobile phone having a speech-recognition software disclosed according to the present invention, has the function of speech-recognition, and the mobile phone can work together with the first card  1   a , which forms a complete remote payment system that having functions of embezzling and faking resistance according to the present invention. 
         [0041]    Please refer to  FIG. 3 , which is a illustrating diagram according to the second embodiment of the present invention. The radio piece  10  is configured within a second mobile phone  2   b , and the speech-recognition piece  24  and the controller  12  are configured in a second card  1   b . The speech-recognition piece  24  and the controller  12  are electrically connected to the radio piece  10  in contact or not. As the idea has been described in  FIG. 2 , a wireless communication module that the second mobile phone  2   b  certainly has, could function as the radio piece  10  that is need in the remote payment according to the second embodiment of the present invention. This kind of design can make use of the electrical pieces of the mobile phone efficiently and saving from configuration of more other pieces. In addition, because both the controller  12  and the speech-recognition piece  24  are configured within the second card  1   b , the second card  1   b  can corporate with any other mobile phone that has an ability of electrical connection therewith and wireless transmission, which forms the remote payment system of the present invention. The characteristic mentioned above is important when the second mobile phone  2   b  loses power or fails to work. Besides, the second mobile phone  2   b  also has a microphone  20  that connects electrically to the radio piece  10 , and hence a first voice can be input by the microphone  20  and connected electrically to the speech-recognition piece  24  configured in the second card  1   b  to be speech-recognition/identification. 
         [0042]    Please refer to  FIG. 4 , which is a illustrating diagram according to the third embodiment of the present invention. All the pieces disclosed in  FIG. 2  are configured within a third mobile phone  2   c , which means the pieces already configured within the mobile phone  2   c  could function as the radio piece  10 , the speech-recognition piece  24  and the controller  12  by setting corresponding software in addition. Even the pieces of the remote payment system of the present invention are all additional in stead of the pieces already configured within the mobile phone  2   c , the mobile phone  2   c  is still convenient. The third embodiment showed in  FIG. 4  has an advantage that it is not necessary to consider how to exchange the information between the mobile phone and the remote payment system such as showed in  FIGS. 2 and 3 , because the remote payment system of the present invention has been incorporated within the mobile phone. 
         [0043]    Please refer to  FIG. 5 , which is a diagram illustrating the operating principle according to the fourth embodiment of the present invention. The remote payment system  1  includes the radio piece  10 , the controller  12  electrically connected to the radio piece  10 , and the speech-recognition piece  24  electrically connected to the radio  10  and the controller  12 , which is showed as  FIG. 2 . In addition, there is a predetermined voice stored in the speech-recognition piece  24 , which is used for speech verification. The steps of the present invention include: the first step, beginning, which is the step of the activation of the remove payment system  51 . Usually, the activation of the remote payment is because of the electric wave delivered from the merchant&#39;s recipient device being detected by the remote payment system. The second step is to input a first voice to the remote payment system  1 , which is the step of inputting a first voice  52 , and the first voice is exactly the voice the owner spoke to the remote payment system  1  before. The first voice usually consists of several words of which are the currency name and the transaction amount. The third step is comparing  53  the first voice with the predetermined voice, which means comparing the voice-print of the inputting voice with that of the predetermined voice. In normal cases, the voice of human speaking will not be exactly the same in each time even if the voice is formed from the same words spoke by the same person, and hence if the results of the comparison with first voice are too close, that means the inputted voice is very possible a recorded or a synthesized voice. To avoid this deficiency, there is a recognition zone defined previously based on the predetermined voice. If the inputted voice is a recorded or a synthesized voice, these so-called “false voice” will have the similarity over the recognition zone in compare with the predetermined voice, and if the inputted voice is not spoke by the original user, the similarity will fall below the recognition zone. Only when the comparing result falls within the recognition zone, the system will go to step  4  to authorize the controller  12  to subtract an amount of a money from a sum, which is the step of the authorized charging  54 . After the step  4 , the sum stored in the controller  12  will decrease and the transaction will be carried out. Further, the first voice can not only function as a password of the remote payment but also can be the indication of the amount of the money subtracted from the sum, such as USD twenty-three or twenty-three USD in the form of the currency name plus the money amount or the money amount plus the currency name. By the voice-recognition/identification, not only the security of the remote payment system is improved but also the transaction amount is specified, which will not prolong the processing time any more. In compare with the present invention, the prior art that uses a short-message delivered by a mobile phone and inputting a password by the button is not only complicated but also take a long time. 
         [0044]    Please continue referring to  FIG. 5 , the remote payment system further includes a step  3 - 1 : if the result of the voice-verification not falls within the recognition zone, the system will provide a random generated code and request the user to repeat  53 - 1 . This code is usually a simple sentence, and the system will compare the voice of the code with the predetermined voice, and if the result falls within the recognition zone, the system will implement the step  4  of authorized charging  54 , if not, the system will implement ending  55 . After the step  4  of authorized charging  54 , the system will also implement ending  55 . Based on the mention above, the present invention also provides a copy-protected device that has a predetermined voice. When a inputted voice is identified the same as the predetermined voice, that is identifying result falls over the recognition zone, the user will be requested to input an additional voice. The predetermined voice mentioned above is stored in the speech-recognition piece  24  showed in  FIG. 2  to  FIG. 4  and  FIG. 6 , and the voice inputting here is just like the step  2  of inputting the first voice  52  as showed in  FIG. 5 . If the copy-protected device identifies the inputted voice the same as the predetermined voice, the device will implement the step  3 - 1  of repeating  53 - 1  as showed in  FIG. 5 . 
         [0045]    Please refer to  FIG. 6 , which is a illustrating diagram according to the fifth embodiment of the present invention. The speech-recognition piece  24  of the remote payment  1  according to the present invention is configured in a reading device  6 . In addition, a radio transceiver  60  connected electrically to a fixed microphone  62  is configured in the card reader  6 . In general, the card reader  6  is set in a certain place such as a merchant or an entrance. The radio piece  10  and the controller  12  are configured in a third card  1   c  that functions as a gate security card or a remote payment system. A user can input a voice by the fixed microphone  62 , and the voice will be identified by the speech-recognition/identification piece  24 . If the identifying result falls within the recognition zone, the controller  12  will subtract an amount of a money from the sum, or permitting the entrance if the third card  1   c  functions as a gate security card. The working steps is just like those described above, which will not be described in detail. 
         [0046]    Please refer to  FIG. 7 , which is a diagram illustrating the another operating principle according to the sixth embodiment of the present invention. The steps showed in  FIG. 7  includes: step ( 1 ), beginning  71 , which means the activation of the remote payment system of the present invention. In general, the remote payment system is activated by a special radio wave from card reader and received by the radio piece  10 . The next step ( 2 ) is the first verification phase  7   a , which is used to verify if the user is exactly the owner. The step ( 2 ) includes two stages: the stage ( 2 - 1 ) and the stage ( 2 - 2 ). The stage ( 2 - 1 ) is the first password inputted stage  7   a   1 , which is used to decide if inputting a password and verifying the password in the first verification phase  7   a . The stage ( 2 - 2 ) is the first password verified stage  7   a   2 , which is used to verify if the inputted password is correct, when a user decides to verify the password in the first verification phase  7   a . In addition, in the first verification phase  7   a , the choice of “yes” or “no” in the stage ( 2 - 1 ) of the first password inputting stage  7   a   1  and the password inputting in the stage ( 2 - 2 ) of the first password verified stage  7   a   2 , can be implemented by speaking or inputting in keypad buttons. 
         [0047]    Please continue referring to  FIG. 7 , if it is needed to input the password in the step ( 2 - 1 ), the system will implement the step ( 2 - 2 ) to verify the inputted password. If the password passes through the verification, the system will implement the step ( 3 ) of transaction amount realizing  72 , which means the system will query if the user realize the transaction amount, and if the answer is no, the system will implement the step ( 3 - 1 ) of showing the transaction amount received from the merchant by a radio signal. The step ( 3 - 1 ) is the step of receiving the signal of the transaction amount and showing  72 ′. The next is the step ( 4 ) of inputting the currency name and the amount  73 , and if the answer to the step ( 3 ) is yes, the system will skip the step ( 3 - 1 ) and implement the step ( 4 ) directly. 
         [0048]    Please refer to  FIG. 7 , when the step ( 4 ) has finished, the step ( 5 ) of the second verification phase  7   b  begins, which is used to verify if the user is the owner. The step ( 5 ) includes two stages: the stage ( 5 - 1 ) and the stage ( 5 - 2 ). The stage ( 5 - 1 ) is the second password inputting stage  7   b   1 , which is used to decide if inputting a password and verifying the password in the second verification phase  7   b . The stage ( 5 - 2 ) is the second password verification stage  7   b   2 , which is used to verify if the inputted password is correct when a user decides to verify the password in the second verification phase  7   b . The next step is step ( 6 ) of receiving the signal of the transaction amount  74  in case we didn&#39;t do  72 ′ to get transaction amount, and further is the step ( 7 ) of verifying the currency name and the amount  75 . If the result of the step ( 7 ) is correct, the step ( 8 ) of the authorized charging  76  will begin. Final is the step ( 9 ) of ending  77 , and the whole procedures according to the sixth embodiment of the present invention and the transaction are finished. In addition, in the second verification phase  7   b , the choice of “yes” or “no” in the stage ( 5 - 1 ) of the second password inputting stage  7   b   1  and the password inputting in the stage ( 5 - 2 ) of the second password verification stage  7   b   2 , can be implemented by speaking or inputting in keypad buttons. 
         [0049]    The another characteristic of the embodiment showed in  FIG. 7  is that the step ( 2 ) and the step ( 5 ) can be implemented alternatively. For the purpose of security, one of the forgoing two steps will be bound to be implemented. The following is the description in detail. 
         [0050]    Please continue referring to  FIG. 7 , if the password verification is decided to be implemented in step ( 2 ) of the first identifying phase  7   a , the response to the stage ( 2 - 1 ) of the step ( 2 ) must be “yes”, and the password need to be inputted in the stage ( 2 - 2 ). If the password inputted is correct, the system will implement the step ( 3 ) of the transaction amount confirmation  72 , and the response to the stage ( 5 - 1 ) of the step ( 5 ) of the second password inputting stage  7   b   1  could be “no,” and the system will implement the step ( 6 ) of receiving the signal of the  74 . The next is the step ( 7 ) of identifying the currency name and the amount  75 , and if the result of the step ( 7 ) is correct, the system will implement the step ( 8 ) of authorized charging  76  and final step ( 9 ) of ending  77 . Instead, if the password verification is implemented in the second verification phase  7   b , the response to the stage ( 2 - 1 ) of the step ( 2 ) must be “no”, and the system will implement the step ( 3 ) of the transaction amount confirmation  72 . The next step ( 5 ) and followed procedures are the same as those described above. In addition, there is another operating method provided according to the embodiment of the remote payment system of the present invention. When the user decides to be verified in the first verification phase  7   a , the system will skip the step ( 5 ) and implement the step ( 6 ) directly. On the contrary, if the use did not be verified in the first verification phase  7   a , the system is forced to implement the stage ( 5 - 2 ) of the second password verification stage  7   a   2  in the step ( 5 ) of the second verification phase  7   b , which is used to verify if the password inputted by the user of the remote payment system is correct. The steps followed are the same as described above. 
         [0051]    Besides, as showed in  FIG. 7 , if the password verification fails in the stage ( 2 - 2 ) of the first password verification stage  7   a   2  or in the stage ( 5 - 2 ) of the second password verification stage  7   b   2 , or the step ( 6 ) of receiving the speech signal of the transaction amount  74  takes too time, or the result of the step ( 7 ) of verifying the currency name and the amount  75  is wrong, the system will implement the step ( 9 ) of ending  77  directly. 
         [0052]    Further, the verification both in the step ( 2 ) and the step ( 5 ) can be implemented by speech/speaker recognition that has been introduced clearly above. Therefore, the user can either use keypad to input transaction amount and authorization password to authorize transaction to perform an authorization transaction. Or just speak the transaction amount to system, and system automatically recognize inputted transaction amount and using voice-print as authorization password to come out authorized transaction by one utterance. 
         [0053]    Please refer to  FIG. 8 , which is a diagram illustrating the further another operating principle according to the seventh embodiment of the present invention. The steps showed in  FIG. 8  includes: step ( 1 ), inputting the currency name and transaction amount  81 , which means the remote payment system is activated by the transaction amount inputting. The currency name and transaction amount can be inputted by speaking or keypad buttons, and then the system will implement the next step ( 2 ) of the password inputting and verification  82 , which is used to verify if a user is exactly the owner, and the password inputting in the step ( 2 ) also can be implemented by speaking or keypad buttons. If the user passes the verification in step ( 2 ), the system can directly implement the step ( 3 ) of authorized charging. Final is the step ( 4 ) of ending  85 , and the whole procedures according to the seventh embodiment of the present invention and the transaction are finished. 
         [0054]    In addition, if the user didn&#39;t make sure the transaction amount, the only thing the user need to do is just make the remote payment system pass through the card reader, and the system will implement the step ( 1 - 1 ) of receiving the signal of the transaction amount and showing  81 ′. The transaction amount in the step ( 1 - 1 ) is delivered from the merchant by a radio signal. After the system showing the transaction amount, the user has to confirm if the currency name and the amount is right, which means the system will implement the step ( 1 - 2 ) of the currency name and the amount confirmation  82 ′. The response of the user to the confirmation in the step ( 1 - 2 ) may just be a simple word, such as “Yes”, or a repeating of the currency name and the amount inputted by speaking or keypad buttons. If the confirmation result of the step ( 1 - 2 ) is right, the system will implement the step ( 2 ) of the password inputting and verification  82 . However, if the user does not pass the confirmation in step ( 1 - 2 ), or the system receives no confirmation signal, the system will implement the step ( 4 ) of ending  85 . On the contrary, if the user passes the verification of the system in step ( 2 ), the system will implement the step ( 3 ) of authorized charging and then final step ( 4 ) of ending  85 , and the whole procedures will also be completed. 
         [0055]    For improving transaction safety, if the user identifies the currency name and the amount showed in step ( 1 - 1 ) by repeating the transaction amount in voice, the system will further implement the step ( 1 - 3 ) of identifying the currency name and the amount  83 ′ to make sure that the user truly realize the transaction amount. 
         [0056]    On the contrary, in order to save transaction time, if all inputting and confirmation steps are carried out in speaking, the step ( 2 ) of the password inputting and verification  82 , the step ( 1 - 2 ) of the currency name and the amount confirmation  82 ′, and the step ( 1 - 3 ) of identifying the currency name and the amount  83 ′, can be finished in one step by the speech/speaker recognition technique provided in the present invention and introduced clearly in early description. When the system identifies the currency name and the amount by comparing the user&#39;s voice signal and the received signal from the card reader, the user will also be verified by comparing the voice-prints of the inputted voice signal with the basic voice stored in the system previously at the same time. In other words, the system could automatically recognize inputted transaction amount and using voice-print as authorization password to come out authorized transaction by one utterance. 
         [0057]    Based on the mention above, the remote payment system of the present invention has a great creativeness in the transaction security and fraud preventing. The creativeness of the present invention is based on that the transaction amount will be inputted by a first voice, and the remote payment system will identify the first voice to confirm if the user is the real owner. In addition, in order to prevent a voice recorded previously by a fraud from confusing the verification, the remote payment system of the present invention provides another protecting mechanism. If the first voice inputted is too similar with a predetermined voice stored in the remote payment system previously, the remote payment system of the present invention will ask the user to input a second voice to be verified. The phrase “too similar” here means the identification result falls over a recognition zone that defined based on the predetermined voice stored in the remote payment system. The identification results can roughly be divided into three types: within the recognition zone, below the recognition zone and over the recognition zone. If the identification results falls below the recognition zone, the remote payment system will recognize the inputted voice as a wrong voice and implement the step of ending directly. If the identification result falls over the recognition zone, which means the inputted voice is almost the same with the predetermined voice, the system will recognize the inputted voice as a recorded or synthesized voice, and also implement the step of ending directly. In another embodiment, the remote payment system will implement the step of password identifying before authorized charging or inputting the transaction amount, to make sure that the user is the real owner.
