Description
Technical field
The present invention relates to a kind of encryption system and method, particularly relate to a kind of encryption system and method for intelligent terminal local file.
Background technology
Along with the development of mobile communication, intelligent terminal has been deep into the every aspect of people's daily life.Usually, people can on intelligent terminal the local file such as storing audio, video, photo, text.
Although there is multiple file ciphering technology in prior art, can't by the encryption of intelligent terminal realization to local file itself.Wherein, existing computer file ciphering method the making for realizing mainly through third party software being applied to intelligent terminal, or be just encrypted for this locality application.
As, intelligent terminal desktop arranges an encryption folder; Be encrypted by the intelligent terminal application pulled in this encryption folder.Wherein, the dynamic authorization code obtained by third party's intelligent terminal, submits to the dynamic authorization code administrative client that file data user terminal loads, and the file data of this intelligent terminal is carried out to the encrypting and decrypting management of dynamic authorization code.But the method application flow is complicated, is unfavorable for that user uses.
For another example, the Chinese invention patent that application number is 201410576218.1, denomination of invention is " encryption method based on mobile terminal data file " discloses a kind of encryption method based on mobile terminal data file, in dynamic authorization code client, increase encryption handling module, realize the encryption handling of dynamic authorization code to mobile terminal storing card data file, realize dynamic authorization code uploads high in the clouds data file encryption handling to mobile terminal; The described encryption handling to mobile terminal storing card data file, comprises the steps: S1, starts dynamic authorization code client, click dynamic authorization code encryption administration module; The file menu of S2, the encryption of selection needs, or select the individual data file of sensing needs encryption further; S3, click acknowledgement key complete encryption, generate encryption folder or generate data file encryption; S4 or the encryption case migration of described data file encryption or backup being moved to setting store; S5, when data file encryption is read in needs deciphering, click data file encryption, or open cryptographic storage case and click described data file encryption; S6, background system comparison, by mobile terminal related authentication parameter, decipher dialog box by rear ejection; S7, open dynamic authorization code client, read dynamic authorization code, submit to deciphering dialog box; Or automatic activation dynamic authorization code client, acquiescence reads dynamic authorization code and submits to deciphering dialog box; S8, background system comparison dynamic authorization code, as then successful decryption after comparison success; Described encryption handling mobile terminal being uploaded to high in the clouds data file, comprises the steps: S9, clicks and select data file to submit to high in the clouds to store, eject encryption and play window; S10, when selecting to encrypt, then click and confirm to start dynamic authorization code encryption; S11, encrypted rear generation encryption folder or generate data file encryption; S12, encrypted data files passe high in the clouds storage server to be stored; S13, when needs deciphering read cloud storage encryption data file time, click described backup data file encryption at mobile terminal; Or first download described data file encryption to mobile terminal, then click described data file encryption; S14, background system comparison, by the certification of mobile terminal correlation parameter, decipher dialog box by rear ejection; S15, open dynamic authorization code client, read dynamic authorization code, submit to deciphering dialog box; Or automatic activation dynamic authorization code client, acquiescence reads dynamic authorization code and submits to deciphering dialog box; S16, formerly by after the certification of dynamic authorization code account identity authorization system, background system restarts comparison dynamic authorization code, as then data file successful decryption after comparison success.
For another example, the Chinese invention patent that application number is 201310430733.4, denomination of invention is " a kind of intelligent terminal application encipher method " discloses a kind of intelligent terminal application encipher method, comprises the following steps: on intelligent terminal desktop, arrange an encryption folder; Be encrypted by the intelligent terminal application pulled in described encryption folder, and generate one and apply corresponding protection password with described intelligent terminal; When detect for the intelligent terminal application in described encryption folder open request time, generates one and inputs the prompting of described protection password; Whether the password of checking input is consistent with described protection password, if unanimously, then opens the application of described intelligent terminal.
But technique scheme has following defect:
(1) do not provide the convenience for intelligent terminal local resource to encrypt, be only to provide the corresponding application of computer resource encryption;
(2) complex operation, cannot provide the operation of efficient convenience for user;
(3) in portion of techniques scheme, need the staged files position during file encryption, after deciphering, needing to revert to original position could use file data, easily obscures.
