Description
Technical Field
The invention relates to the technical field of communication, in particular to a method for generating an external identification code of an active card.
Background
An active card (e.g., an active highway toll card) includes an internal identification code (also referred to as an internal ID) and an external identification code (which is printed on the housing of the active card, also referred to as a housing number). For example, in a highway toll system, the internal ID is a main tag number used, and is commonly used in the processes of issuing cards at toll stations, identifying routes and receiving cards at toll stations. However, when some special conditions occur, a computer database record of a certain active card needs to be searched, and the internal ID of the active card is not displayed, so that the searching of the internal ID of the active card through the shell number becomes a necessary searching means.
In the prior art, the correspondence between the shell number and the internal ID of the active card is realized by a method of randomly generating and recording a correspondence relationship when the active card leaves a factory, and this method has the advantage that unspecified persons cannot obtain the internal ID information of the active card and modify database data by deciphering the shell number. It does have some significant disadvantages: when the internal ID and shell number corresponding relation table attached during factory shipment is lost, or the active card fails or is powered off, and the like, the situation that the active card cannot read the card is realized, and the situation that the corresponding relation between the shell number and the internal ID of the active card is required to be searched is almost impossible.
Disclosure of Invention
Aiming at the technical problem that the use of an active card is not ideal due to the fact that the corresponding relation between an internal identification code and an external identification code of the active card in the prior art is random, the invention provides a method for generating the external identification code of the active card, which comprises the following steps: acquiring an internal identification code of the active card; and generating an external identification code of the active card according to the internal identification code and a predetermined mapping relation, wherein the predetermined mapping relation comprises logic transformation.
By adopting the method for generating the external identification code of the active card, provided by the invention, the internal identification code of the active card is obtained, and then the external identification code of the active card is generated according to the internal identification code and the preset mapping relation. When the active card cannot read the card (for example, the active card fails or is out of power), the related technical personnel can know the corresponding relation between the internal identification code and the external identification code of the active card through the logic transformation and simultaneously ensure the safe use of the active card.
Additional features and advantages of the invention will be set forth in the detailed description which follows.
Drawings
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention and not to limit the invention. In the drawings:
fig. 1 is an exemplary flowchart of a method of generating an external identification code of an active card according to one embodiment of the present invention.
Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is an exemplary flowchart of a method of generating an external identification code of an active card according to an embodiment of the present invention, which may include the steps of, as shown in fig. 1:
Since the setting of the numbers of the internal identification code and the external identification code is generally set according to the use situation, in order to more clearly illustrate the idea of the present invention, the identification code in the highway toll collection system is taken as an example, wherein the internal identification code is generally set to 8-bit 16-system data, and the external identification code is generally set to 8-bit 10-system data. It should be understood that the number of bits of the internal and external identification codes may be set by those skilled in the art according to the actual application, and the present invention is not limited to this exemplary number of bits. In this example, step 1002 may further perform the following steps:
and 11, subtracting the first N specific codes of the internal identification code to generate an internal identification code H-01 after code subtraction, wherein the N specific codes are used for identifying the area using the active card, N is a positive integer and is less than the digit of the internal identification code (for example, N is less than 8), characters with special meanings in the internal identification code can be extracted by the operation, and then the remaining identification codes are converted, kept secret and the like, so that the accurate conversion and the safety of data can be effectively ensured without changing the meanings of certain characters with special meanings. For example, the first two digits of the internal identification code may be used to identify the use area of the active card, and thus the first two digits of the identification code may be subtracted in step 11 before the operation of conversion is performed. For example, the first two digits of the 8-bit 16-ary internal identification code are subtracted, and the remaining 6-bit 16-ary internal identification code is H-01.
And step 12, converting the internal identification code H-01 after code subtraction into binary data H-02 so as to facilitate the operation of the computer. For example, the remaining 6-bit 16-ary internal identification code H-01 may be converted into 24-bit binary data H-02.
Step 13, shifting and/or exchanging one or more (for example, one data bit, two data bits … … or all data bits) data bits of the binary data H-02, and ensuring the uniqueness of the converted data during the operation to generate the shifted and/or exchanged binary data H-03.
And 14, performing complement operation on the shifted and/or exchanged binary data H-03 (namely adding a binary number with a specified number of digits before or after a specified position of the data) to generate binary data H-04 corresponding to the number of the external identification code digits of the active card, for example, performing 0 complement operation according to the number of digits required by 8-digit decimal to generate corresponding binary data H-04.
And step 15, converting binary data H-04 corresponding to the number of the external identification code of the active card into decimal data H-05 to generate the external identification code of the active card.
Wherein, the step 13 shifts and/or swaps one or more data bits of the binary data H-02, and generating the shifted and/or swaped binary data H-03 may include:
the binary data H-03 after shifting is generated by circularly shifting left or circularly shifting right the designated data bits of the binary data H-02 by a predetermined number of bits, for example, the binary data H-03 can be circularly shifted left or circularly shifted right by 1, 2 bits from the 1 st bit.
Alternatively, one or more data bits of the binary data H-02 are exchanged to generate the exchanged binary data H-03, for example, the 1 st bit and the 3 rd bit, and the 2 nd bit and the 5 th bit of the binary data H-02 may be exchanged.
Or, circularly left-shifting or circularly right-shifting the appointed data bit of the binary data H-02 by a predetermined bit number to generate shifted binary data H-02-01; and exchanging one or more data bits of the shifted binary data H-02-01 to generate exchanged binary data H-03. For example, the 1 st bit may be shifted to the left or right circularly by 1 bit, and the 1 st bit and the 3 rd bit of the binary number after shifting may be swapped, the 2 nd bit and the 5 th bit may be swapped, and so on.
Preferably, after step 15, it is also possible to perform:
step 16, adding an M-bit identification code to the external identification code of the active card, where the M-bit identification code is used to identify that the predetermined mapping relationship exists between the external identification code of the active card and the internal identification code, where M is a positive integer, for example, adding a two-bit identification code "01" to the external identification code of the active card, so as to identify the external identification code of the active card, which is generated according to logic transformation, and finally printing the external identification code (10-bit 10-system data) with the identification code added to an assigned position of the active card housing.
According to the embodiment of the invention, when the active card cannot read the card (for example, the active card fails or is out of power), a related technician can calculate the internal identification code of the active card according to the external identification code of the active card and the inverse mapping of the predetermined mapping relation, so that the problem that the internal identification code cannot be acquired in the prior art is solved:
step 21, the external identification code H-10 of the active card is converted into binary data H-20. For example, corresponding to the example described above, an 8 digit decimal number H-10 is converted to binary data H-20.
And 22, carrying out code reduction on the binary data H-20 to generate the binary data H-30 with predetermined bits, for example, the binary data is subjected to code reduction to 24 bits.
Step 23, shifting and/or exchanging one or more data bits for the binary data H-30 to generate shifted and/or exchanged binary data H-40.
Step 24, converting the shifted and/or exchanged binary data H-40 into 16-system data H-50, for example, into 6-bit 16-system data H-50;
and 25, adding the N-bit specific code to the front of the 16-bit 16-system data H-50 to generate the internal identification code of the active card, for example, adding the 2-bit specific code to the front of the 6-bit 16-system data H-50 to generate the internal identification code of the 8-bit 16-system active card.
Preferably, for an external identification code added with an M-digit identification code (i.e. corresponding to the 10-digit decimal external identification code of step 16), the method may also perform the following steps before step 21:
and 20, subtracting the front M-bit identification code to generate an external identification code H-10 of the active card. For example, the first 2 digits are subtracted to generate an 8-digit decimal external identification code H-10.
Wherein, the step 23 shifts and/or swaps one or more data bits of the binary data H-30, and generating the shifted and/or swaped binary data H-40 may include:
and circularly right-shifting or circularly left-shifting the appointed data bits of the binary data H-30 by a predetermined number of bits to generate shifted binary data H-40. For example, the bit may be shifted cyclically right or left by 1 bit starting from bit 1.
Or, one or more data bits of the binary data H-30 are exchanged to generate the exchanged binary data H-40. For example, bits 1 and 3, and bits 2 and 5 of binary data H-30 may be swapped.
Or, exchanging one or more data bits of the binary data H-30 to generate the exchanged binary data H-30-01, and circularly right-shifting or circularly left-shifting the appointed data bits of the exchanged binary data H-30-01 by a predetermined number of bits to generate the shifted binary data H-40. For example, the 1 st bit and the 3 rd bit may be swapped, the 2 nd bit and the 5 th bit may be swapped, and then the 1 st bit may be shifted to the right or left circularly by 1 bit.
It should be understood that the values of N and M, and the predetermined number of bits and the designated data bits can be selected by one skilled in the art according to practical circumstances, and the present invention is not limited thereto.
By adopting the method for generating the external identification code of the active card, provided by the invention, the internal identification code of the active card is obtained, and then the external identification code of the active card is generated according to the internal identification code and the preset mapping relation. When the active card cannot read the card (for example, the active card fails or is out of power), the related technical personnel can know the corresponding relation between the internal identification code and the external identification code of the active card through the logic transformation and simultaneously ensure the safe use of the active card.
