Detailed description of the invention
Fig. 1 schematically shows flow chart of the invention.
Specific embodiment
The embodiment of the present invention is described in detail below in conjunction with attached drawing, but the present invention can be defined by the claims
Implement with the multitude of different ways of covering.
Term introduction:
(1) IMEI (International Mobile Equipment Identity): i.e. usually said mobile phone sequence
Number, mobile phone " string number ", for identifying the mobile communication equipments such as each independent mobile phone in mobile telephone network, be equivalent to shifting
The identity card of mobile phone.Sequence number shares 15 bit digitals, and preceding 6 (TAC) are Type Approval numbers, represents type of cell phone.Then 2
Position (FAC) is last assembly number, represents the place of production.6 (SNR) are strings number afterwards, represent production sequence number.Last 1 (SP) is general
It is 0, is check code, it is spare.International mobile equipment identification number is generally affixed in the fuselage back side and outer packing, while existing in hand
In machine memory, it can be inquired by inputting * #06#.
(2) ANDROID_ID: when Android device starts for the first time, system can generate one 64 numbers, and handle at random
This number is preserved in the form of 16 system character strings, and the character string of this 16 system is exactly ANDROID_ID, works as equipment
The value can be reset after being resumed default setting.
(3) IDFV (identifier For Vendor): 6.0 system of iOS increases newly for replacing
The interface of uniqueIdentifier.It is to give Vendor identity user, each equipment is answered the affiliated same Vender's
With inner, there is identical value.Vender therein refers to application provider, but exact point is said, is anti-by the DNS of BundleID
The preceding two parts turned are matched, if identical is exactly the same Vender, such as com.somecompany.appone,
For the two BundleID of com.somecompany.apptwo, just belong to the same Vender, shares the same idfv's
Value.Unlike idfa ((identifierForIdentifier)), the value of idfv is one surely to get, so very
It is adapted as the main id of internal user behavioural analysis, carrys out identity user, substitutes OpenUDID.If user will belong to this
All App of Vender are unloaded, then the value of idfv can be reset, i.e., reset the App of this Vender again, the value of idfv and before not
Together.
(4) APP (application): application program.
Usual cell phone apparatus has an IMEI that can identify Unique Device, but since IOS and android system are all corresponding
It obtains IMEI with program to be limited, at present it is not yet found that the method for effect can be got effectively on two platforms
IMEI.ANDROID_ID and IDFV is respectively adopted in Android and ios platform to identify Unique Device in the present invention.
There are problems that safety the sharing of above-mentioned existing file, the present invention is quasi- to provide a kind of safe sharing files
Method.For the participator of file, it is possible to specify share file to by the bound device of participator:
After user installs APP and successful log for the first time, unique device id and user name can be bound.
(1) when the first user will share file to second user, it is possible to specify whether the file shared away, which needs, is tied up
Locking equipment ID.
(2) when server-side receives sharing request, its corresponding device id can be searched according to the user name of target.
(3) using the device id got then file encryption is shared again.
(4) after the equipment of second user binding opens APP, it will be seen that the first user of user when the listed files of oneself
It is shared with the encrypted document of oneself.
Since the intelligent mobile phone platform of current mainstream includes two platforms of Android and IOS, setting in the present invention
Standby ID is respectively ANDROID_ID and IDFV on the two platforms.In addition, device id is generating when user's initialization logs in
Afterwards, it can choose and Make Alias for device id, while being stored in the database of rear end, such as: the millet mobile phone of Zhang San.When other use
When file is shared to Zhang San in family, the designated equipment for being shared with him can choose.
In this way, the present invention indicates bound device by the unique identifier of mobile phone, differentiated in order to facilitate sharing files person,
It supports when bound device, takes an alias for new equipment, each user can bind more than one equipment.
The system manager of server end possesses the audit to apparatus bound situation, binding, the permission of unbundlings.For having added
Close sharing, but the file that mobile phone terminal is not downloaded, if administrator obtains sharing files person and eliminates sharing, by participator
File after decryption cannot successfully be got.
When the recipient of file will download the file shared, need for its device id to be transmitted to server, server is tested
After demonstrate,proving successfully, downloading encryption version can be just provided for it.The decryption of document is only seen by current App ability real time decrypting
Version.
After file recipient downloads file, lack of competence is shared again by this APP, even if being searched by file system,
Encrypted shared document can only be navigated to, it is utterly useless being gone out by sharing.
Compared with the sharing files method on cell phone platform in the prior art, the invention has the characteristics that: (1) exist
Different mark ID has been respectively adopted to distinguish Unique Device in IOS and Android platform.The mode of holding equipment alias is shared
File person more easily discriminates.(2) and unlike traditional sharing files to user, the sharing in the present invention is shared to " use
Name in an account book+equipment ", the two must simultaneously meet, indispensable.(3) file shared safely based on device id, the only equipment are
There is key (device id) that file is decrypted, other any equipment are all not all right, therefore even if bulk-breaking is let out by other means
Draining to other equipment also can not correctly open.
By adopting the above-described technical solution, the invention enables can only open the text shared by the equipment by participator
Part can't see file by other equipment, and after the equipment by binding checks file, it is also to add that cache file, which is copied away,
Ciphertext part, to improve the safety of sharing files.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
