Abstract
A method for generating a permanent serial code of the product based on flash memory includes creating serial code generation interface, running application, invoking said interface, generating a serial code according to the time of opening the application and the content of memory, putting the serial code to end of boot sector, opening the application again, examining the integrity of serial code, and returning the serial code if it is, or generating the serial code again if it is not.
Description
Invention field
The present invention relates to the method that a kind of permanent sequence code that is used for the unique identification of product generates, especially a kind of method for generating permanent sequence code of products based on the FLASH storage medium.
Background technology
Because the needs of interim logistics management in the life of product, identification during product is used needs, the needs of the collection of repair message nuclear school management, and the needs encrypted of user profile, the demand of the unique machine recognition that can not revise of various products number is very important.Therefore, require that in this sequence code of computing machine randomness is arranged, uniqueness and property throughout one's life, and the program that can only be employed reads, can not revise.That uses similar sequence code technology also has the sequence code of mobile phone, the sequence code of hard disk, the sequence code of PC BIOS.The method that generates this sequence code has following several method usually.
1, when the production line general assembly, keeps a typing in the machine test procedure and select.By the product line worker production sequence code of machine is input in the machine.Program is saved in machine somewhere with the sequence code of typing, is read by application program when needing again.The shortcoming of this method is that product line worker's running time is long, influences production efficiency, cost height, and easy typing mistake.
2, use the serial number of machine, this way is fairly simple, and cost is little, but sequence code can not be read by handheld digital device, so this method can not be considered.
In addition, present many digital products, because it is the flash memory FLASH ratio of performance to price is day by day ripe, increasing based on the product of FLASH storage medium.Products such as for example various handheld device PDA, palm PC.And be the product of FLASH for storage medium, its unique recognition sequence sign indicating number may be modified on the FLASH if write, and does not resemble the said goods, PC BIOS etc. for example, and sequence code is placed among the ROM and can be modified.
Have sequence code to need to generate automatically again, if artificial the generation, not only efficient is low but also very easily make mistakes.And the cd-rom recorder of products such as handheld device PDA, palm PC can't be programmed, so burning automatically.
Summary of the invention
The object of the present invention is to provide a kind of method for generating permanent sequence code of products based on the FLASH storage medium, it not only can generate the unique identifier of product automatically, but also can forever keep.
Another purpose of the present invention is to provide a kind of method for generating permanent sequence code of products based on the FLASH storage medium, and the seed that it generates has random, and generative process is simple to operation.
The object of the present invention is achieved like this:
A kind of method for generating permanent sequence code of products based on the FLASH storage medium which comprises at least following steps:
A, set up sequence code and generate interface;
B, enter an application program;
C, invocation code sequence generate interface;
The time factor that d, increase application program are opened, the formation sequence sign indicating number;
E, sequence code is placed in the boot section, the record significant notation can prevent to be modified.
Further, also comprise increase internal memory factor in the described steps d, content formation sequence sign indicating number.
For being unlikely to influence the read operation of other programs of boot section, among the described step e sequence code is placed on the least significant end of boot section.
In addition, for prevent effective sequence code in use owing to some normal reasons, and influence is read, and more than described step e can repeat once, sequence code is duplicated more than one deposit respectively.
After sequence code was set up, for determining whether legal finishing, described step comprised further that also if the integrality of checking sequence sign indicating number complete, is then confirmed, returns sequence code when opening above-mentioned application program once more; Imperfect, then re-execute the generation step, the formation sequence sign indicating number.
The present invention compared with prior art has tangible advantage:
1, the reference value of strong its seed of sequence code generation randomness is a point of fixity, so the confidentiality height.
2, be generated as full-automatic process, control simply, do not need optional equipment and means.
3, sequence code permanent storage can illegally not changed and be deleted.
Description of drawings

Fig. 2 is a sequence code position view of the present invention.
Embodiment
Referring to Fig. 1,2, the present invention is a kind of method for generating permanent sequence code of products based on the FLASH storage medium, which comprises at least following steps:
1, sets up sequence code and generate interface;
2, enter an application program; For example when opening master message for the first time, the user generates.Because make seed that randomness be arranged.If adopt once the generation of starting shooting, seed randomness may not have fixed reference, so just generate when opening for the first time the application program of master message.
3, invocation code sequence generates interface;
4, the time of opening, memory content according to above-mentioned application program, the formation sequence sign indicating number; For example, master message is after having shown other items of information, and invocation code sequence generates interface, and sequence code generates interface according to system time, also can be again according to the formation sequence sign indicating numbers such as memory content of product.
5, for preventing modification to sequence code, sequence code can be written on the BootLoader district, this zone can not changed because of operation such as program updates.The judgement of writing in enhancing simultaneously, unless special request, all operations of writing this piece zone will be left in the basket.Sequence code is placed in the boot section, and the record significant notation can prevent to be modified.For being unlikely to influence the read operation of other programs of boot section, sequence code generates least significant end and the flag sequence sign indicating number effective (AABB) of interface with sector, sequence code burned Bootloader place.
Sequence code generates interface and returns sequence code with the form of ASCII character.
In addition, for prevent effective sequence code in use owing to some normal reasons, and influence is read, behind the formation sequence sign indicating number, can repeat once more than, sequence code duplicated more than one deposits respectively.For example duplicate 8 sequence codes, leave in respectively in the boot section, with the box lunch one problem is arranged after, can also use remaining, fail unless the full sequence sign indicating number reads all, just sequence code can not re-use.
After sequence code was set up, for determining whether legal finishing, whether sequence code possessed integrality, also further comprises the step of checking sequence sign indicating number integrality in the above-mentioned steps.Open above-mentioned application program once more for example during master message, utilize checking algorithm sequence of calculation sign indicating number, and check with being verified as.If sequence code is complete, then confirm, return sequence code; Imperfect, then re-execute the generation step, the formation sequence sign indicating number.
That is to say, second when opening master message still invocation code sequence generate interface, but this moment sequence code whether generate an interface checking sequence sign indicating number legal, if the legal sequence code of just returning.
Method benefit of the present invention is can be with the generation full automation of sequence code, and need not increase optional equipment.Can not be illegally modified simultaneously.
