After the equipment message that client-side program is sent, the lost devices are positioned and followed the trail of by centralized management backstage.
Based on Fig. 2,3, the procedure of detailed description location tracking portable terminal.
(1) first, the embedded client bootstrap in BIOS.
BIOS is the initialism of English " Basic Input Output System ", and literally rear Chinese is exactly "
Basic input output system ".In fact, it is one group of program being cured in computer on mainboard on a rom chip, and it is preserved
Self-check program and system self-starting journey after the programs of the most important basic input and output of computer, system set-up information, start
Sequence.Its major function is to provide the bottom, most direct hardware setting and control for computer.BIOS is directly solderable at present
In computer hardware, turn into inalienable part on computer main board.
BIOS is stored in ROM (Read Only Memory, read-only storage).Data inside ROM is in ROM
In manufacturing process, it is programmed into factory with special method, content therein can only be read to change, once burning is entered
Go, whether the data that user is able to validate only write-in is correct, it is impossible to changes again.If it find that data has any mistake, then
Only give up and do not have to.
Based on this features of BIOS, client bootstrap forms whole as the one of submodules of BIOS
Bios program module.It is written in the ROM of mainboard.And it is associated with computer self-test system self-triggered program.So as to avoid
It is stolen or lose notebook in extreme circumstances：It is formatted, refitting system and GHOST cause client software to be broken
It is bad, it can not position and follow the trail of the notebook information.
Client bootstrap is present in the BIOS in notebook computer, forms a set of program curing product, it is impossible to quilt
Change and delete, because itself and notebook core position are integrally formed, and start before operating system.Fundamentally break away from pair
The dependence of operating system, reach read-write capability of the control to operating system, so as to complete the deployment to client-side program.
Solidify embedded client bootstrap in BIOS and be largely divided into two parts, a part is to be used to control to operation
The driver of system read-write function, available for analysis operation system file structure and fdisk structure, position fdisk
The index of part is read and write, is ready for the deployment of client-side program.Above-mentioned driver can be used for entering hard disk NTFS subregion
Row read-write, can be installed to UEFI BIOS's by UEFI BIOS Driver Model by the read-write capability for NTFS partition
Realized in SimpleFileSystemProtocol.
Another part is exactly client-side program, and T programs Trigon.Exe is converted into binary file, is compiled into BIOS
In, it is present in as a submodule in BIOS module with binary code in bios program.Above-mentioned driver can determine that
The off-position of client-side program in a hard disk, the binary code of the client-side program solidified in BIOS is read, and with two
The form of binary file is discharged into hard disk, and the binary code write in hard disk can be identified by operating system, and can be transported
OK, terminal user can not carry out direct file operation to the binary code of write-in under an operating system, avoid user to hard
The artificial of client-side program is deleted or modified in disk.In view of each manufacturer BIOS Size the problem of, T programs are compiled by c language
Write complete, when being write, pass through second-compressed again, ensure that it has less binary code size, Yi Mianzao
Into BIOS compilings but, there is mistake when or BIOS is run.
(2) when BIOS power-up starts, client bootstrap therein is started.
When BIOS power-up starts, the loading of driver in bootstrap, driver startup pair are triggered in some stage
Operating system partition and the analysis of file system,
When carrying out zoned format judgement, above-mentioned driver is it is first determined whether be hard disk, if not then no longer entering
One step analyzes zoned format；If hard disk, then need to judge whether zoned format is NTFS format, if it is further positioning
With release client-side program to specified location, if not driver is then exited, os starting is carried out.In analysis subregion
During form, the structure of subregion is parsed, the standard interface function provided by driver is realized to NTFS partition
Read-write, the positioning to specific specific file path is realized, and obtain other information.Hard disc data is analyzed by ad hoc rules,
Navigate to document location index, it may be determined that file original position and the offset of section in a hard disk, calculated simultaneously according to offset
Determine client-side program off-position.
Driver goes to read known NTFS after SimpleFileSystemProtocol installations by this agreement
The T programs of particular path (client-side program off-position determined by i.e.) in subregion；If the state returned when reading is
EFI_NOT_FOUND, then without the file found under specified NTFS partition path, illustrate there is no T programs under specified path, drive
Program reads the client-side program binary code being stored in BIOS, according to the client-side program off-position of determination, passes through
T programs in BIOS are written to hard disk position (the i.e. client-side program specified by SimpleFileSystemProtocol agreements
Off-position), T programs are stored in hard disk in the form of binary file, and this binary code can be known by operating system
Not, and can run.
After T programs to be written to the hard disk position specified, start-up operation system stages can be entered；
For the power-on operation again of terminal, equally to judge to read T programs under specified path in next start process
State；If the state read is EFI_FOUND, proves that T programs have been present, zoned format can be verified by MD5
On whether existing file and the file to be write consistent.If the result is consistent, it is not required to separately write again, if
The result is inconsistent, shows the T programs or destroyed on zoned format, or is changed, then needs to re-write, so as to ensure
T programs can correctly be run.
Illustrated by code below and hard disk information is obtained by agreement, position hard disk off-position, offset, then
The program in BIOS is discharged to specified location, so as to complete the release work to hard disk program.
(3) after os starting, client-side program is run.
After os starting, the various configuration parameters of operating system are detected, it is determined that there is client-side program in startup item
In the presence of after, run client-side program, after client-side program startup optimization, obtain the identifier of notebook computer, and establish and in
Entreat the network service of server.
The identifier of notebook computer can be obtained with a variety of methods.For common identifier, program verification can be used
Code, the account of user, application program sequence number or specific password identify notebook computer.But the present invention is special due to it
Surely the field used is related to computer security, and common identifier can not meet its requirement in specific environment identification equipment.
The identifier that the present invention uses is hidden, is most difficult to eliminate or replaces.These identifiers include the network interface card of notebook computer
Physical address (MAC Address), BIOS sequence numbers, the hardware configuration of hard disk serial number and computer.These parameters be it is most reliable,
Even in hard disc of computer under conditions of formatting, it will not also lose.But in formatting procedure, operating system, application
The data such as program, user account will lose.
Though several parameters cannot ensure 100% identification notebook more than.Because hard disk drive can be replaced.
BIOS sequence numbers may can pass through special instrument in some situations without the even MAC Address of BIOS sequence numbers and machine
Modify, so as to cause identifier to change.But statistics shows, only the user of only a few may take change, this
Ensuring that can take symbol identified above to identify notebook computer.Identified identifier is exactly notebook computer in the present invention
Physical network card address/MAC address as identification notebook computer unique identifier.
MAC (Medium/MediaAccess Control, medium access control) MAC Address is to be embodied in
.MAC addresses inner NetworkInterfaceCard (network interface card, NIC), are also hardware address, are by 48 bits/bit length (6 words
Section/byte, 1byte=8bits), the numeral composition of 16 systems.0-23 positions are called tissue unique identifier
(organizationally unique), it is the mark for identifying LAN (LAN) node.24-47 positions are by producer oneself point
With, wherein the 48th is multicast address flag bit.The physical address of network interface card is typically by the burned network interface card of network interface card manufacturer
EPROM (a kind of flash chip, generally can be erasable by program), mark of really being rely when what it was stored is transmission data are sent
The address of the computer of data and the main frame of reception data.
It is that main frame, Ran Houjin are identified by physical address that is, during the physical transfer of network bottom layer
Row data transfer.It must be globally unique.For example Ethernet card, its physical address are the whole of 48bit (bit)
Number, such as：44-45-53-54-00-00, it is stored in a manner of machine readable in HPI.Ethernet address management organization
(IEEE：Institute of Electrical and Electric Engineers) by ethernet address, that is, the various combination of 48 bits, it is divided into some independent
Continuation address group, the producer for producing ethernet nic just buys one of which, when specifically producing, one by one by unique address assign with
Too network interface card.MAC as notebook unique identifier is the pith of user account information, is that notebook is lost in positioning search
Key point.With the popularization of the electronic equipments such as notebook and wireless network, every notebook is owned by wireless and wired now
Two kinds of physical network card addresses.For user when using notebook computer, it is impartial to open wired and wireless chance.I.e. same
When, can open it is wireless or open it is wired can also open simultaneously it is wired and wireless two in physical network card.The present invention
On the premise of guaranteeing to be accurately positioned and following the trail of the electronic equipment, unique identifier takes wireless and wired two kinds of physical network cards
The combination of MAC Address.But for the MAC Address of mobile external NIC, there is unpredictalbe movement and replace possible in it
Property, the unique identifier not using it as notebook computer.
(4) location tracking is carried out using client-side program.
The framework mode of location tracking system is based on client and central server pattern in the present invention, and client-side program needs
To be coordinated and be managed by central server.New task is assigned by the information for collecting and analyzing the client transmitted.
T programs are run under operating system, because T programs need the support of network linking, and because of the otherness of each system, in power-on operation
After system starts, now T programs are had been written under the path for the NTFS partition form specified, it is necessary to which T programs do timing inspection
Survey after determining network linking success and run.
When user runs client-side program for the first time, it is necessary to which registered user's account, fills in user's basic condition, correspondent party
The relevant informations such as formula, addresses of items of mail are simultaneously submitted to central server using the identifier of the electronic equipment as unique mark.So
The notebook computer unique identifier is just bundled into together with the relevant information of user, is registered in central server.The user
Information is mutually bundled with equipment so that computer is closely connected with its user account.Use can be related to by the information of the registration
Family.
For having registered user, when user has found that corresponding notebook computer has been stolen or lost in account
When, it can be sent to central server and notify the equipment to be stolen.Central server the equipment is stored in immediately it is stolen or
Person loses blacklist, starts function of search.
After network linking success, client-side program enters operation, obtains notebook computer unique identifier first,
Such as：After the machine MAC, central server is submitted to, central server receives the network information that client-side program transmits, analyzed
And extract identifier, searched for based on identifier after determining relative users login account information, be classified as in blacklist it is stolen or
The equipment of loss is compared judgement, if comparative result is consistent, can be identified as equipment that is stolen or losing.
User account information modification is arranged to lose or be stolen equipment by central server, and is sent a notification message and returned
Back to client-side program.After client-side program receives corresponding notification message, it is possible to find the computer is now by central service
Device is defined as losing or being stolen equipment, starts to gather the positioning of the notebook computer and tracked information, such as：The machine MAC, detection
Time, the machine Ip addresses, gateway address, external proxy server address and ethernet router, wireless access point coordinate information,
Central server is sent to, is handled by central server and is stored, location tracking is carried out to target device.
Prior art is not formatted simply in memory, and program is not unloaded, delete or operating system does not have
In the case of by refitting, the equipment can be just navigated to, and the system proposed by the present invention for being used to position notebook is with different sides
Method is run.Even if the stolen notebook computer either lost is deleted or unloaded even operating system quilt in client-side program
Refitting can also navigate to the notebook computer lost or be stolen in the case of either formatting.
In extreme circumstances, equipment is stolen, and operating system is reset, when machine is restarted, in BIOS
Drive load program starts first, and detection client deployment program whether there is, it is found that client-side program is lost, then discharge client
Program is held to specified location.Transfer to operating system client-side program.After os starting, visitor is found that in specified location
After the program of family end, client-side program is run.Client-side program still is able to the information of the equipment of collection to be sent to central service
Device processing.
The lost devices or all information of stolen equipment being collected into by client-side program may serve to positioning should
Device location.Lose or the external address of stolen notebook can by webserver provider (NSP) come
Determine the determination position of external address.External address tracks loss by NSP routing tables or stolen equipment finally route ground
Location, it is determined that loss or stolen notebook computer final outlet address.By NSP data, services, then pass through the machine Ip addresses essence
Really to loss or the particular location of stolen notebook computer.By user's enrollment status information, it is determined that loss or stolen pen
Remember the home subscriber of this computer.
It can be subject in addition by way of (GPS) satellite positioning module that client-side program activates notebook computer connection
Spotting.If the notebook computer does not have satellite navigation module, its position can be still determined by other means, only
It is error in precision be present.For example, loss or stolen notebook computer wirelessly have been started up, then can passes through its week
The position for enclosing more than at least three hotspot is determined.Then central server is using collected by client-side program
Ethernet router, accessing wirelessly point coordinates determines to be connected to the position of belonging network equipment.In the case, lose or
Person is stolen the position of notebook computer it was determined that still precision is less than the coordinate determined by GPS navigation system, and its precision can be high
In the geographical position followed the trail of by external address bit.
In order to intuitively position the address location of loss or stolen equipment, provide in central server and shown by map
Show that output location tracking is stolen or loses notebook computer position, central server is collected into loss or stolen device coordinate
After information, just carry out after corresponding Coordinate Conversion is sent to map server, after map server receives corresponding coordinate, finally
The position of the notebook computer is marked by conspicuous color according to the coordinate of loss or stolen notebook computer.
