Abstract
The invention discloses a method of clearing fragmented data of Android phone. The method comprises the following steps: S1, starting an Android underlying service; S2, paring file systems of partitions; S3, clearing all fragmented data of idle areas; S4, clearing all fragmented data of normal areas; The method of clearing fragmented data of Android phone is able to distinguish normal areas, idle areas and fragmented areas in partitions, thoroughly clear all fragmented data in idle areas and data of the fragmented areas in the normal areas, thereby ensuring data privacy of the public, and preventing baleful stealing of privacy data.
Description
Technical field
The present invention relates to field of information security technology, particularly a kind of method removing Android mobile phone crumb data.
Background technology
Android smartphone has SOS, independent operating space, can install third party software voluntarily, expanded function is powerful, inseparable with the life of people, data in mobile phone information wherein relates to the work, study, life, contacts, finance, leisure, amusement, emotion etc. of people, is very precious intangible asset concerning individual or company.
The mechanism of Android system file management can cause there is crumb data in mobile phone EMS memory and SD card, and when carrying out file management, disk fragments arrangement can be carried out to mobile phone EMS memory and SD card, the private data of user is very likely there is in fragment, these crumb data by some date restoring software rejuvenations on the market out, can cause the leakage of user privacy information.
Therefore, the process of these data is become very important.The at present also unspecial technology for eliminating to crumb data in Android mobile phone subregion on the market.In sum, develop a kind of method by scanning key word removing Android mobile phone crumb data and seem particularly important.
Summary of the invention
The present invention is directed to the defect of prior art, propose a kind of method removing Android mobile phone crumb data, effectively can solve above-mentioned prior art Problems existing.
To achieve these goals, the technical solution used in the present invention is: a kind of method removing Android mobile phone crumb data, comprises the following steps:
S1: enable Android underlying services;
S2: the file system of subregion is resolved;
S3: all crumb data removing clear area;
S4: all crumb data of normal region in removing.
As preferably, described S1 comprises the following steps:
S101: shielding Android system restriction;
S102: call physical layer interface, obtains the data of mobile phone subregion with self-defining block size;
S103: call the data that kernel function obtains mobile phone subregion, uses Android ADB Socket to set up with Android system and communicates;
S104: obtain the key message of corresponding sector and record by sending order.
As preferably, described S2 comprises the following steps:
S201: obtain partition system parameter;
S202: obtain subregion normal region and clear area, and obtain normal region and address, clear area;
S203: obtain the crumb data in subregion normal region.
As preferably, described subregion comprises DATA subregion and SD card subregion.
As preferably, described S3 comprises the following steps:
S301: the clear area size obtained according to S202, creates the file of formed objects;
S302: write null value is to file;
S303: file is filled out clear area stored in mobile phone;
S304: delete this file.
As preferably, described S4 comprises the following steps:
S401: the position and the size that calculate crumb data according to 203;
S402: crumb data is read to internal memory;
S403: null value write memory is covered all crumb data;
S404: write storage medium by with the data covered.
Compared with prior art the invention has the advantages that: the normal region in subregion, clear area, debris field can be distinguished; The debris field data of all crumb data in comprehensive removing clear area and normal region, have ensured the data-privacy of the public, and the malice of preventive inoculation to private data steals behavior.
Accompanying drawing explanation
Fig. 1 is the main flow chart of the embodiment of the present invention;
Fig. 2 is the detail flowchart of step S1 of the present invention;
Fig. 3 is the detail flowchart of step S2 of the present invention;
Fig. 4 is the detail flowchart of step S3 of the present invention;
Fig. 5 is the detail flowchart of step S4 of the present invention.
Embodiment
In order to describe the specific embodiment of the present invention in detail, below in conjunction with accompanying drawing to illustrate:
As shown in Figure 1, S1: enable Android underlying services;
S2: the file system of subregion is resolved;
S3: all crumb data removing clear area;
S4: remove all crumb data in normal region.
As shown in Figure 2, described S1 comprises the following steps:
S101: shielding Android system restriction; The effect of Android system is only the transmission of data, so shield the restriction of Android system, to realize the removing of bottom data.
S102: call physical layer interface, obtains the data of mobile phone subregion with self-defining block size;
S103: mobile phone is as server, and PC end, as client computer, uses Android ADB Socket to set up with Android system and communicates;
S104: obtain the key message of corresponding sector and record by sending order.
As shown in Figure 3, described S2 comprises the following steps:
S201: obtain partition system parameter, comprise partitioned organization, subregion path, carry partition name etc.;
S202: obtain subregion service condition, comprise total size and used size, distinguishes normal region and clear area, and obtains normal region and address, clear area;
S203: obtain size of data in block size and block, to distinguish the crumb data obtained in normal region.
Above-mentioned subregion comprises DATA subregion and SD card subregion.
As shown in Figure 4, described S3 comprises the following steps:
S301: the clear area size obtained according to S202, creates the file of formed objects;
S302: file, to file, fills up by write " 0x00 ";
S303: file is filled out clear area stored in mobile phone;
S304: delete this file, removes the crumb data that clear area is all.
As shown in Figure 5, described S4 comprises the following steps:
S401: the information obtained according to S203, calculates position and the size of block internal fragment data by usage space in block size and block;
S402: by all pieces of internal fragment digital independent to internal memory;
S403: " 0x00 " write memory is covered all crumb data;
S404: by with in the storage medium of the data covered write mobile phone, complete the cleaning of all normal regions internal fragment data.
More than describe and set forth detail to fully understand the present invention, but the present invention can also adopt other to be different from this describing mode to implement, therefore the present invention is not limited to above disclosed specific embodiment.
