As shown in Figure 3, when data backup device and Data Recapture Unit are positioned at same terminal, data back up method and the data reconstruction method of terminal comprise the following steps:
Step S1: pre-service is carried out to the data of tag memory storage, forms data link table and data link table mapping table;
First the current geographic position at terminal place is gathered, and the geographic position current to terminal upgrades and preserves, and the geographic position of the terminal of last update is come foremost; Pre-service is carried out to the data of tag memory storage, particularly, the geographical location information of preservation can be utilized to mark the data message stored in terminal, the content of mark includes but not limited to the geographic position of the terminal that data are corresponding, the self-information of data, the classification of data, wherein the self-information of data includes the title of data, store path, the size of data and data the need of encryption etc.; Preserve the data that marked, set up data link table as shown in table 1, and the data link table of flag data is classified according to the classification of data, form data link table mapping table as shown in table 2.Often have new when flag data adds data link table, all will carry out chained list sort operation.
Table 1
Table 2
As shown in table 2, the data that tag memory can store up by data link table mapping table, according to geographical location information dividing data classification, are classified as same data category by same geographical position range.
Step S2: back-up storage is carried out to data link table, and when data need encryption, first data are encrypted and carry out back-up storage again;
Read data link table, backup is carried out to the data marked and preserves; When data need encryption, before back-up storage, operation is encrypted to these data.
When Backup Data, the geographic location area that each data category is corresponding can be determined, particularly, to the relevant geographic position under each data category, according to corresponding computing method, determine the geographic location area that each data category is corresponding, particularly, can be the data point corresponding with geographic position by the data transformations under each data category, under can comprising this data category, the radius in the smallest circular region of all data points increases new border circular areas that certain distance formed as geographic location area corresponding to this data category.
Afterwards, when having new data to need to mark in terminal, step S1 and step S2 is repeated.
Step S3: obtain the current geographic position of terminal, and be the data of current operational in terminal by date restoring corresponding for the current geographic position of terminal.
Obtain the current geographic position of terminal, the geographic location area corresponding according to current operational data in terminal is carried out judgement with the geographic position received and is compared, and exports corresponding comparative result; If find, the geographic position of terminal there occurs change, when needing to carry out data exchange, then reading all data under corresponding data category, carry out recovery operation, is the data of the current operational in terminal by all date restoring under terminal current geographic position corresponding data classification; Data exchange is carried out, then without operation if do not need.
Particularly, geographic position current for terminal can geographic location area corresponding to service data be compared with in present terminal, when the current geographic position of terminal is away from this geographic location area edge certain distance, then can judge that the geographic position of terminal changes, terminal has been in another geographic location area, from data link table mapping table, search the data category belonging to geographic position of current renewal, and be the data of the current operational in terminal by all date restoring under this data category.
The present invention is when the geographic position of terminal changes, can according to pre-set pattern, the data corresponding to geographic position before terminal first back up, and then by date restoring corresponding for current geographic position be in terminal can service data, achieve the related data of terminal inner isolation and maintain secrecy.
