Embodiment

Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is described in detail.

Among the embodiment of the present utility model, as shown in Figure 1, DPF comprises memory 10, display 20 and controller 30, and wherein memory 10 is in order to deposit data such as picture, literal and music; Display 20 is connected with memory 10, in order to the data of storage in the display-memory 10; Controller 30 is connected with display 20 with memory 10, provides interface to the visit of memory 10 and by display 20 for the user in order to control.

In embodiment of the present utility model, as shown in Figure 2, the memory 10 of DPF comprises shared memory cell 101 and at least one encrypts memory cell 102, for example the memory in the DPF has the memory space of 200M to store data, can set wherein 100M memory space as shared memory cell 101, this shared memory cell 101 is similar with the data space in the present digital photo frame, can be stored, visit and revise by everyone; Set other 100M memory space as encrypting memory cell 102, this encryption memory cell 102 can be stored user's private data, visit the data in this encryption memory cell, the password that needs the input user to set in advance.In embodiment of the present utility model, this encryption memory cell 102 can have a plurality of, two of examples only among Fig. 2, but be not limited thereto.Certainly for memory more multi-form subregion can also be arranged, for example in encrypting memory cell 102, further be divided into read-only memory unit and can edit memory cell, if entering, the user encrypts memory cell 102, also need visit can edit memory cell, then also need input to enter this and can edit the needed password of memory cell.The division of above memory block 10 is an example of the present utility model only, is not limited thereto.

In embodiment of the present utility model, as shown in Figure 3, the controller 30 of DPF comprises indicative control unit 301, the detecting unit 302 that is connected with indicative control unit 301, the password setting unit 303 that is connected with detecting unit 302 with indicative control unit 301 respectively, password acquiring unit 304, and the password authentification unit 305 that is connected with password acquiring unit 304 with indicative control unit 301.Indicative control unit 301 provides the interface in order to control display 20 for the user.Detecting unit 302 is in order to detect user's Access status, promptly detecting the user is that password will be set, still need visit the data of shared memory cell 101 or need the data of the subregion of access rights, if the user need be provided with password, this detecting unit 302 is informed password setting unit 303, and password setting unit 303 triggers indicative control unit 301 control displays 20 and comes display password that the page is set; If triggering indicative control unit 301 control displays 20, the data of user's desire visit shared memory cell 101, this detecting unit 302 come the needed data of explicit user; If the visit of user's desire needs the subregion of access rights, this detecting unit 301 is informed password acquiring unit 304, and password acquiring unit 304 triggers indicative control unit 301 control displays 20 and comes the display password input page.Password acquiring unit 304 is visited the password of encrypting memory cell 102 data in order to obtain from the user, and is sent the password that obtains to password authentification unit 305.Password authentification unit 305 verifies to the password that password acquiring unit 304 obtains that according to the password that sets in advance if be proved to be successful, this password authentification unit 304 informs that indicative control unit 301 control displays 20 come the needed data of explicit user; If authentication failed, this password authentification unit 304 are informed the needed data of indicative control unit 301 refusal explicit users.

In embodiment of the present utility model, the password setting unit 303 of the controller 30 of DPF is in order to set in advance and to store the Crypted password of user to the subregion that needs access rights.When the user need be provided with password to the subregion that needs access rights, this password setting unit 303 triggers indicative control unit 301 control displays 20 display passwords the page is set, the user carries out the setting of password according to the indication of the password setting page, the modes such as several different methods, for example handwriting input, button input, audio frequency input, fingerprint input, IMAQ that are provided with of this password.The set-up mode of above password is an example of the present utility model only, is not limited thereto.

In embodiment of the present utility model, please continue with reference to shown in Figure 3, the controller 30 of DPF comprises that also the specific cryptosystem that is connected with detecting unit 302 with indicative control unit 301 is provided with unit 306, in order to set in advance and to store the user to needing the subregion unlocking pin of access rights.The subregion that in the user desires reference to storage, needs access rights, when carrying out password authentification, if the user inputs N all failure of password continuously, then digital photo frame enters lock-out state, needs the subregion of access rights can not be accessed, needs the user to import specific cryptosystem information and carries out release, N user wherein can define voluntarily, N=3 for example, i.e. user's password of three mistakes of input continuously, promptly DPF enters lock-out state.The setting of specific cryptosystem wherein also can be adopted multiple modes such as handwriting input, button input, audio frequency input, fingerprint input, IMAQ.The set-up mode of above password is an example of the present utility model only, is not limited thereto.

In embodiment of the present utility model, different access rights are set for the different subregions in the memory, avoid all users can both browse or delete all interior data of DPF.At first the user enters the password setting interface, if need to select a certain subregion of access rights, the user can adopt multiple modes such as handwriting input, button input, audio frequency input, fingerprint input, IMAQ that password is set, the password setting module 303 of controller 30 receives the password of user's input, and corresponding partition data is encrypted.Follow-up user's desire is visited this subregion, the user need input password, the password acquiring unit 304 of controller 30 receives this password and sends to password authentification unit 305 to be verified, if the password of user's input is identical with the password that sets in advance, then to the needed data of corresponding subregion decoding and displaying user, if the password of user's input is different with the password that sets in advance, then refusal shows the needed data of user.

In embodiment of the present utility model; if the user inputs all failures of password N time continuously, then digital photo frame enters lock-out state, needs the subregion of access rights all can not be accessed; need the user to import specific cryptosystem and carry out release, so more effectively protect the critical data in the DPF.

In addition, can adopt multiple modes such as handwriting input, button input, audio frequency input, fingerprint input, IMAQ that password is set among the embodiment of the present utility model, the encryption that improves user's logarithmic code photo frame is handling.

The above is disclosed to be preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; the form that can also change, these versions also should be considered as protection range of the present utility model.
