Abstract
The invention discloses a kind of mobile platform transparent encryption method, it comprises encrypting step and decryption step, encrypting step comprises user and preserves file, whether file system driver is encrypted data according to the configuration determination of user, file driving system is encrypted data and is saved to the sub-steps such as storage medium, decryption step comprises user and opens application program, application program prepares file reading information, file system driver judges whether application program has decrypted rights, file driving is to decrypt data and be back to the sub-steps such as application program, the present invention just can to the private file in user's mobile communication equipment without the need to user's memory cipher, data are encrypted, decryption processing, user does not worry that the privacy etc. of oneself leaks to the Internet completely.
Description
Technical field
The present invention relates to a kind of mobile platform encryption method, particularly mobile platform transparent encryption method.
Background technology
At present, mobile Internet has progressively goed deep into the life of people, and various mobile communication equipment is had more visitors or business than one can attend to, such as smart mobile phone, panel computer etc., has become the necessity of people's life.But how guaranteeing the various private file in mobile communication equipment, data are not leaked to the Internet, is a problem in the urgent need to address.Particularly current cloud stores the application of power, people can by deposit data beyond the clouds, be convenient to use anywhere or anytime, but worry that again the private data of individual is leaked, such as, mobile communication device user uploads to high in the clouds the photo oneself taken and video, but worries that again the privacy photo of oneself or video are leaked to the Internet beyond the clouds, and such example is many innumerable in our life.In prior art, user oneself can arrange the data that codon pair uploads and be encrypted, but complicated so after all, and user needs the password remembeing oneself, and these simple passwords are easy to just be cracked, and the development of form, impels the generation of transparent encryption.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of private file information easy to use, that mobile communication equipment can be ensured not leaked to the mobile platform transparent encryption method of the Internet.
The object of the invention is to be achieved through the following technical solutions: mobile platform transparent encryption method, it comprises encrypting step and decryption step, and described encrypting step comprises following sub-step:
(1) user preserves file, and data stream transmitting is to file system driver;
(2) file system driver according to the configuration determination of user the need of to data encryption;
(3), when needing encryption, the data after encryption to data encryption, and are saved to storage medium by file system driver;
(4), when not needing encryption, file system driver directly sends data to storage medium;
Described decryption step is the inverse step of encrypting step, comprises following sub-step:
(1) user opens application program, and application program prepares file reading information;
(2) according to the configuration of user, file system driver checks whether application program has decrypted rights;
(3), when application program has a decrypted rights, file system driver extracts the corresponding document in storage medium and to its deciphering, then the file after deciphering is back to application program;
(4), when application program does not have a decrypted rights, file system driver extracts the corresponding document in storage medium, if file is encrypted, returns error message to application program, if file unencryption, directly to application program backspace file.
File system driver of the present invention comprises a configuration database, preserves the information that user's application programs is configured and safeguards in described configuration database.
The invention has the beneficial effects as follows: the present invention can guarantee the private file of the mobile communication equipment of user, data message is not leaked to the Internet, and user is without memory cipher, user eliminates the complicated processes of encryption and decryption operation when using common encryption method, for user brings great convenience.

Fig. 2 is decryption step flow chart of the present invention.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, mobile platform transparent encryption method, it comprises encrypting step and decryption step, and as shown in Figure 1, described encrypting step comprises following sub-step:
(1) user preserves file, and data stream transmitting is to file system driver;
(2) file system driver according to the configuration determination of user the need of to data encryption;
(3), when needing encryption, the data after encryption to data encryption, and are saved to storage medium by file system driver;
(4), when not needing encryption, file system driver directly sends data to storage medium;
As shown in Figure 2, described decryption step is the inverse step of encrypting step, comprises following sub-step:
(1) user opens application program, and application program prepares file reading information;
(2) according to the configuration of user, file system driver checks whether application program has decrypted rights;
(3), when application program has a decrypted rights, file system driver extracts the corresponding document in storage medium and to its deciphering, then the file after deciphering is back to application program;
(4), when application program does not have a decrypted rights, file system driver extracts the corresponding document in storage medium, if file is encrypted, returns error message to application program, if file unencryption, directly to application program backspace file.
File system driver of the present invention comprises a configuration database, preserves the information that user's application programs is configured and safeguards in described configuration database.
After using the present invention, the information such as photo are uploaded to high in the clouds by user, the information such as photo are encrypted when transmission, when user downloads the information such as photo from high in the clouds, use picture browsing TO, when opening, the information such as photo are deciphered, user does not know the process of encryption and decryption, and all concerning user, these are transparent.
File on mobile communication equipment, leave Flash etc. in not easily on volatile media, for the read-write of file, have to pass through the file system driver of the operating system that mobile communication equipment uses, the file system driver of the operating system that therefore can use at mobile communication equipment writes encryption and decryption code, file system driver sets up configuration database, store the information that user's application programs is configured and safeguards in configuration database, have the authority of declassified document in order to configure which application program.
Claims (1)
