Abstract
A GPS autonomous navigator of car for protecting the intellectual property of optical map disc is characterized by that the ID code A and the version code B of optical map disc are used to generate a result F through arithmatic operation and the F is compared with the user password to determine if the normal working program can be run.
Description
Affiliated technical field
The present invention relates to a kind of autonomous navigator for automotive global location system; be that (wherein GPS is the abbreviation of English Globel Position System to a kind of automobile GPS autonomous navigator; mean GPS), refer to a kind of automobile GPS autonomous navigator that can protect map CD intellecture property especially.
Background technology
The automobile GPS autonomous navigator that has CD drive is universal just day by day, brings great convenience for the driving people.The map CD that making is used for automobile GPS autonomous navigator is a costly engineering.Even to this day, the whole world does not still have a kind of automobile GPS autonomous navigator can effectively prevent to use pirate map CD, how to prevent that achievement from being that map CD developer wishes the important topic that solves by piracy.
Summary of the invention
Can not distinguish the deficiency of legal and pirate map CD in order to overcome existing automobile GPS autonomous navigator; the invention provides a kind of automobile GPS autonomous navigator; this navigating instrument can stop to use pirate map CD, protection map CD intellecture property, helps to safeguard map CD developer's rights and interests.
For reaching this purpose, the present invention takes following measure:
1, this identity sign indicating number sequence number A unmodifiable, mutually different, that be used to protect map CD intellecture property is set in every automobile GPS autonomous navigator machine.
2, use the map CD of band version sequence code B.
3, every automobile GPS autonomous navigator disc types that can read is determined by password C.C is generated by A and B, and generating algorithm D grasps in CD developer hand.Algorithm D informs the hardware production firm of automobile GPS autonomous navigator by the CD developer simultaneously.When the user buys new CD and obtains version sequence code B from dealer, to announce the A sign indicating number of his navigating instrument by dealer to map CD developer, and then obtain the new password C that map CD developer provides, after the user imported automobile GPS autonomous navigator with password C, new CD just can be authorized to use.
The A difference of first, second automobile GPS autonomous navigator, also different with the C that same B generates, even therefore the user of first has copied the user's of second CD and password, also can not on first, use, he need import the new C that is complementary with oneself A, this can only pay from map CD developer and obtain, thereby it is stolen to have stopped the map CD.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing and preferred embodiment.
Fig. 1 is the composition block diagram of automobile GPS autonomous navigator shown in the present.
Fig. 2 is the embodiments of the invention process flow diagram.
Among Fig. 1,1.ROM or FLASHROM, 2. not power down SRAM or EEPROM.ITS information transceiving device, DRAM, gps signal receiving trap, piezoelectric vibration gyroscope and display are message pick-up, program run, data processing and the display device of automobile GPS autonomous navigator.
Embodiment
As shown in Figure 1, this identity sign indicating number sequence number A is stored among ROM or the FLASHROM (1), and the user can read A at any time by automobile GPS autonomous navigator application software.When the new map CD of increasing purchase, the user needs tell map CD developer with A that map CD developer informs a new password C of user's correspondence when the new CD of subsidiary version sequence number B is provided to the user.The user is input to new C in the automobile GPS autonomous navigator by automobile GPS autonomous navigator application software, and the password C of new input is stored among not power down SRAM or the EEPROM (2).Concerning same automobile GPS autonomous navigator, the corresponding password of each paying map CD version, and then constitute a licencing key group E.
Fig. 2 is a synoptic diagram, and embodiments of the invention are shown.When automobile GPS autonomous navigator is started shooting at every turn, at first enter following testing process: read native code A, read map CD version code B, A and B are generated F as a result with algorithm D computing, then each the password C among F and the cipher code set E is compared, if can find an identical person, then enter navigating instrument operate as normal program; If none is identical, judge that then CD is pirate, refusal operation down-stream.
Claims (4)
1, a kind of autonomous navigator for automotive global location system; it is characterized in that: this autonomous navigator for automotive global location system inside is provided with this identity sign indicating number sequence number A of that can be read by the user easily at any time, unmodifiable, as to be used to protect map CD intellecture property, and different autonomous navigator for automotive global location system has mutually different inner identity code A.
2, a kind of autonomous navigator for automotive global location system is characterized in that: this autonomous navigator for automotive global location system uses the map CD that has the version sequence code B that is used to protect map CD intellecture property.
3, a kind of autonomous navigator for automotive global location system; it is characterized in that: this autonomous navigator for automotive global location system has Man Machine Interface and the interface of password C that is used to protect the intellecture property of map CD for user input; password C is after being transfused to; can in machine, be saved, and still exist after the outage.
4, C according to claim 3 is generated by the particular algorithm D that maintains secrecy at map CD developer place by A and B.
