Description of drawings
Fig. 1 is the synoptic diagram that explanation the present invention has the chip card of Presentation Function.
Embodiment
Therefore, the invention provides a kind of chip card, the inner stored data presentation of chip card can be come out, so that the user to be provided bigger convenience with Presentation Function.
Please refer to Fig. 1.Fig. 1 is the synoptic diagram that explanation the present invention has the chip card 100 of Presentation Function.As shown in Figure 1, chip card 100 comprise CPU (central processing unit) (Central Processing Unit, CPU) 110, display device 120, non-volatile (non-volatile) readable and writable memory 130, volatibility (volatile) readable and writable memory 140, power circuit 150, user's interface 160 and card IF.
Non-volatile readable memory write 130 comprises directory area (directory area) 131, secret zones (secret area) 132 and data field (data area) 133.Directory area 131 is used for record data deposit position, length.Secret zones 132 is used for depositing encryption golden key (encryption key) X.Data field 133 is used for storing data encrypted (as the data through the remaining sum after encrypting).In other words, directory area 131 and secret zones 132 stored contents are mainly used to the control signal as CPU (central processing unit) 110, to allow CPU (central processing unit) 110 carry out the chip card operation.
Volatibility readable and writable memory 140 is mainly used to the data (as the data of the remaining sum after the deciphering) after the temporary deciphering, is sent to display device 120 with the data that provide CPU (central processing unit) 110 will be stored in volatibility readable and writable memory 140.So, display device 120 just can be according to the data presentation that is received.In other words, volatibility readable and writable memory 140 is mainly used to the storage data signal, shows to provide CPU (central processing unit) 110 to read this data-signal and to control display device 120 according to this.
CPU (central processing unit) 110 is loaded with chip card operating system, and (Card OS COS), with the operation of process chip card 100, authenticates as card authentication, terminating machine authentication or user etc.CPU (central processing unit) 110 is used for linking up via card IF and external read card device Y.CPU (central processing unit) 110 is the data that received, and according to the stored encryption gold key X of the secret zones 132 of non-volatile readable memory write 130, encrypts, and the data storing that just will encrypt is in the data field 133 of non-volatile readable memory write 130 afterwards.When external read card device Y desires the stored data in the data field 133 of reading non-volatile readable and writable memory 130, CPU (central processing unit) 110 can be according to encrypting golden key X, the data field 133 stored data of non-volatile readable memory write 130 are carried out after the deciphering of correspondence, by card IF, send external read card device Y to; When external read card device Y desire is revised the stored data of non-volatile readable memory write 130, instruction and data that CPU (central processing unit) 110 can be transmitted external read card device Y, encrypt according to encrypting golden key X, and then write the data field 133 of non-volatile readable memory write 130.
User's interface 160 for instance, can be a button, links up so that user and CPU (central processing unit) 110 to be provided.When the user desired the stored data in the data field 133 of direct reading non-volatile readable and writable memory 130, the user can pass through user's interface 160, informs CPU (central processing unit) 110.For example, the user can press the button, and desires user's signal of reading of data to CPU (central processing unit) 110 to send the expression user.When CPU (central processing unit) 110 receives the expression user when desiring user's signal of reading of data, CPU (central processing unit) 110 can be according to encrypting golden key X, data field 133 stored data are decrypted, and be stored in the volatibility readable and writable memory 140, CPU (central processing unit) 110 data that will be stored in volatibility readable and writable memory 140 again are sent to display device 120 then, to show the data after the deciphering.Thus, the user just can pass through user's interface 160, control CPU (central processing unit) 110, and then can be from reading of data on the display device 120.For instance, the user can press the button on the chip card 100, just can read out the data of the remaining sum of chip card 100 from the display device 120 of chip card 100, and not need chip card 100 is moved to the data that scope that the external read card device can link up just can read the remaining sum of chip card 100.
In addition, card IF can be contact card interface, contactless card or combined type card.Combined type card meaning promptly comprises contact and contactless card.When card IF was contactless card, power circuit 150 can receive electric energy from the radiofrequency signal that contactless card received, and converts power supply V to
CCWhen card IF was the contact card interface, power circuit 150 can receive the electric energy that the contact card interface is transmitted, and converted power supply V to
CC Display device 120 comprises a display driver circuit 121 and a display 122.Display driver circuit 121 is used for basis from the signal that CPU (central processing unit) 110 is sent, and comes driving display 122 (boosting with driving display 122 as the signal that CPU (central processing unit) 110 is transmitted).Display 122 can be a bistable state (bi-stable) display, and meaning promptly behind display 122 video datas, does not need continued power, just can continue previous shown data, just changes shown data when next update.
Another advantage with chip card 100 of Presentation Function of the present invention is to provide volatibility readable and writable memory 140 to reduce the required capacity of non-volatile readable memory write 130.For instance, if volatibility readable and writable memory 140 is not set in the present invention, then non-volatile readable memory write 130 just needs the data (needing to distinguish with data encrypted) after another data field stores deciphering, so the capacity of non-volatile readable memory write 130 just need strengthen.Yet because the memory capacity of non-volatile readable memory write is little and cost is high, the memory capacity of volatibility readable and writable memory is big and cost is low, therefore after volatibility readable and writable memory 140 was set, non-volatile readable memory write 130 required capacity just can reduce.On the whole, just can reduce the cost of chip card 100.
In sum, utilize the chip card with Presentation Function provided by the present invention, the user can read stored data in the chip card at any time; And the chip card with Presentation Function of the present invention has the volatibility readable and writable memory, is used for temporal data, and the capacity that can reduce the non-volatile readable memory write effectively is to reduce cost, so that the user to be provided bigger convenience.
The above only is preferred embodiment of the present invention; so it is not in order to limit scope of the present invention; any personnel that are familiar with this technology; without departing from the spirit and scope of the present invention; can do further improvement and variation on this basis, so the scope that claims were defined that protection scope of the present invention is worked as with the application is as the criterion.
