The present embodiment get using after to the access request of multimedia database, first carry out following steps S302 and S303。

S302, parse the access request and this is obtained according to analysis result and apply each destination multimedia file to be visited Type information.

Alternatively, this step can obtain each destination multimedia file using following acquiring way Type information:

According to the file identification information of each destination multimedia file in analysis result, in multimedia database inquiry with Corresponding to record information, because record information includes type information, therefore, type information can be got.Certainly, this step The difference of the rapid type information obtained as needed, acquiring way may also be different.

S303, the type information according to each destination multimedia file, and the type information of default multimedia file With the corresponding relation of access authority information, access authority information corresponding to each destination multimedia file is inquired about.

, it is necessary to the type information of default multimedia file and the corresponding relation of access authority information before this step.Make For a kind of alternative, user can set the corresponding relation in the following manner:

User, which triggers, sets function, and terminal receives the trigger action of user;Generate and show default setting interface, the setting Type information setting option and corresponding access authority information setting option are shown in interface, wherein, type information setting option In user can be provided be manually entered type information, or the type information that terminal supports, Hou Zhexu are selected by drop-down menu Want terminal acquiescence that the type information supported is listed in drop-down menu.Equally, can be provided in access authority information setting option User is manually entered the first authority information or the second authority information, or selects the first authority information or second by drop-down menu Authority information.

For type information setting option, whether user is manually entered type information, or is selected eventually by drop-down menu The type information supported is held, the former needs user's subjectivity to classify multimedia file, and the latter needs terminal automatic or journey Sequence designer's subjectivity is classified to multimedia file, and optionally, the present embodiment provides following three kinds of classification policys To divide multiple media types:

The first is more traditional classification policy, and multimedia file is divided into picture, video or audio, this classification Mode can be directed to picture, video, audio this three classes multimedia file and conduct interviews respectively claim control.The present embodiment will pass through The type information that this classification policy is drawn is referred to as the first sub-type information.

Second is to apply type information that is different and dividing according to multimedia file source, and A is applied for example, deriving from Multimedia file, multimedia file etc. from application B, this mode classification can be according to the level of security of different application Come the claim control that conducted interviews respectively to its caused multimedia file, the class that the present embodiment will be drawn by this classification policy Type information is referred to as the second sub-type information.Multimedia file caused by the higher application of level of security can be arranged to have the Two authority informations, multimedia file caused by the relatively low application of level of security are arranged to have the first authority information.First authority Information is used to characterize the authority for allowing to access, and the second authority information is used to characterize the authority for forbidding accessing.

The third is the type information of the approach difference according to multimedia file source and division, such as is divided into local life Into, other people send or network download, this mode classification can be directed to separate sources approach multimedia file be visited respectively Claim control is asked, the multimedia file as network is downloaded there can be the first authority information, and the multimedia file locally generated can With with the second authority information.The type information drawn by this classification policy is referred to as the 3rd subtype letter by the present embodiment Breath.

If above-mentioned three kinds of classification policys are used alone, scheme is relatively simple, using individually use the first classification policy as Example, user can set the access authority information of picture, video, audio types multimedia file respectively at setting interface, for example, Setting the type information setting option at interface includes three, is also three corresponding to access authority information setting option, user is first Below type information setting option, picture/mb-type is selected by way of drop-down menu, is set in corresponding first access authority information Put item and the first authority information or the second authority information are set, then pass through the side of drop-down menu below Second Type information setting option Formula selects video type, corresponding to set the first authority information or the second authority information in the second access authority information setting option, Select audio types by way of drop-down menu below the 3rd type information setting option again, it is corresponding in the 3rd access rights Information setting option sets the first authority information or the second authority information, finally preserves.

If at least two in above-mentioned three kinds of classification policys are applied in combination, priority policy can be introduced, is set Need to increase priority setting option in interface, specifically, user can complete to set in the following manner:
