Specific embodiment

Permitted to can permit certain user's access file and other users is forbidden to access as described above, file can be set in user The file.In some cases, a group of file is relevant.For example, media player can export media (for example, film, TV programme, music video etc.) digital copies.However, the digital copies of media may include sequentially being accessed to export The various files of media.Since file is relevant, it is thus possible to it is desirable that the file license having the same of all associated documents.

Distributed objects memory block can store the road that identification file (for example, data object) is stored in the position on disk Diameter.Specifically, distributed objects memory block can store the path of multiple groups associated documents.In distributed objects memory block, It can be relevant by file identification based on filename.For example, first group of associated documents can be named as " movie1file1 ", " movie1file2 ", movie1file3 " etc. and second group of associated documents can be named as " movie2file1 ", " movie2file2 ", movie2file3 " etc..When associated documents have related names, the file license of associated documents is changed It may be relatively easy.For example, batch operation can be run to change in filename and there is same prefix (for example, " movie1* ") All Files license.

But if associated documents do not have related names, it may be difficult and/or expensive for changing file.Example Such as, if associated documents have incoherent title, possibly the batch operation for capturing all associated documents can not be defined.Management Member must may parse manually the file of storage, it is related which file be identified, and the license of each associated documents is separately provided.Such as The quantity of fruit associated documents is thousands of, hundreds of thousands of, millions of etc., then this may be especially tediously long.If missing out associated documents (for example, by change associated documents file permit operation, by administrator etc.), then this may damage file security, because The associated documents missed may be accessed for unauthorized user.In addition, if associated documents have incoherent title, then High-level language strategy may be unable to run, such as " All Files relevant to this particular media asset should not can to any user Read " or " all 1080p reproduction of any media asset should be readable to each user on January 1st, 2016."

In addition, if associated documents have related names, then it is possible that accessory problem.For example, distributed objects are deposited Storage area can have multiple subregions and is indexed using filename.Index can be based on the son with root node, various ranks The tree construction of node and leaf node, each leaf node indicates the subregion of distributed objects memory block, so that first of filename Character determines file is assigned to which child node of root node, and second character of filename determines that file is distributed Which child node of child node, and so on, until assigning files to leaf node (for example, point of distributed objects memory block Area).In other words, with related names file can be listed in together in the same subregion of distributed objects memory block (for example, File " movie1file2 " is listed in same subregion with file " movie1file1 ", and file " game1file1 " can arrange Out in another subregion of distributed objects memory block).User equipment can be with Querying Distributed object memory block to identify use Family equipment attempts the position for the various files retrieved.In general, user equipment attempt in extremely rapid succession to retrieve associated documents (for example, Because user is watching film).Because filename can be used to be indexed distributed objects memory block, and because use Family equipment attempts to retrieve the associated documents with related names, so user equipment may be try to store from distributed objects The same subregion in area reads and/or is written to.Therefore, there may be readings between the subregion of distributed objects memory block And/or the uneven distribution of write-in flow, become performance bottleneck so as to cause distributed objects memory block.

Therefore, this document describes a kind of asset store server, associated documents are distributed to asset name and distributed by (1) It is licensed to asset name, the associated documents with uncorrelated title is allowed to be assigned license independently of file naming convention The license of each file is separately provided without user；And/or the revision of (2) based on given filename is to distributed right As memory block is indexed, so that the unlisted same subregion in distributed objects memory block of associated documents with related names In.For example, when asset owner provides a store for one group of associated documents in asset database, asset store server It can permit asset owner and create the asset name for defining associated documents (for example, if associated documents are provided for playing film Produce the title that title may be film).Associated documents can be mapped to asset name and deposit mapping by asset store server Storage is in assets permission database.

In addition, asset store server can permit asset owner as asset name distribution license, and asset store The license distributed can be stored in assets permission database by server.Therefore, when user asks from asset retrieval server When seeking a file, asset retrieval server can (1) queries asset permission database to identify the money for being mapped to the file Produce title；(2) determine whether user is authorized to the file using the asset name of identification；(3) if user is awarded Power accesses the file, then the position of the file is determined by Querying Distributed object memory block；(4) from determining position Retrieve the file；And the file is transferred to user to meet request by (5).

In addition, asset store server can generate hash for each associated documents.For example, hash can be based on corresponding phase Close the file path of file.The hash of generation can be used as the filename that prefix is attached to corresponding associated documents.Even if related text Part can have related names and/or can store in similar position, and the hashed value generated for associated documents can be different (for example, the first character of the hashed value of first associated documents can be with first of the hashed value of second associated documents Character is different).Therefore, because being indexed by tree construction to distributed objects memory block, it is possible to by associated documents It is divided into different subregions.This can reduce continuous reading and/or write request is sent to distributed objects memory block A possibility that identical partitions.Therefore, it is possible to reduce distributed objects storage area data retrieves the waiting time.Extremely below with reference to Fig. 1 Fig. 7 describes the additional detail of asset store server.

Example asset storage environment

Fig. 1 is the block diagram of asset store environment 100 according to an embodiment.As shown in fig. 1, asset store environment 100 include end user device 102, asset owner's equipment 104, asset store server 106, asset retrieval server 108, Asset database 144 searches key database 146 and assets permission database 148.In embodiments, terminal user sets Standby 102 communicate via network 110 with asset retrieval server 108.In addition, asset owner's equipment 104 can be via network 110 It is communicated with asset store server 106.Network 110 can be the public addressable network of linked network, may be by various differences Side's operation, such as internet.In other embodiments, network 110 may include dedicated network, personal area network, local area network, Wide area network, cable system, satellite network, cellular phone network etc. or combinations thereof, each accessible internet and/or from mutual Networking accesses.

Asset database 144 can store data object (for example, file) relevant to various different contents, such as electric Shadow, TV programme, music video, audio books and/or the like.In addition, asset database 144 can store identical content Different editions.For example, asset database can store the content (for example, 480i, 720p, 1080p, 4K etc.), no of different-format With the content (for example, English, French, Spanish etc.) of language, the content with additional feature is (for example, director's comment, delete Scene etc.) and/or the like.Data object can store in various files or catalogue in asset database 144.So And as described herein, the physical location in the asset database 144 of storing data object may not be influenced to distributing to data pair The application of the modification of the license of elephant.Asset database 144 can have several accumulation layers, for example, primary storage, archive storage and/or It is such.Primary storage can be provided than being stored in the archive faster retrieval time, and therefore providing and safeguard may be than depositing It stores up more expensive.

Content may be not stored in individual data object.But content can store in multiple data objects, each Data object represents the small time slice of entire content.Multiple data objects can be accessed continuously to export content.Therefore, Multiple data objects can be relevant.It can be to asset store service via the asset owner of asset owner's equipment 104 Device 106 indicates that multiple associated data objects are being transferred to asset database 144 just to be stored.For example, can be via assets Multiple associated data objects are transferred to assets by storage server 106, asset retrieval server 108 or another system (not shown) Database 144 is to be stored.Asset owner's equipment 104 also can indicate that multiple associated data objects should be with which assets Or sub- assets are associated.As it is used herein, assets can refer to specific content title (for example, film, TV programme, music Video, audio books etc.), and the sub- assets particular version that can refer to assets or format are (for example, the content of 1080p format, French Content, can pass through the particular dispenseds channel such as TV, internet and cellular network distribute content) or assets different reproduction (for example, a collection TV programme).

Asset store server 106 may include data object to the mapper 122 of assets, assets permit manager 124, Search key generator 126 and asset storage management device 128.The mapper 122 of data object to assets can be configured as Data object is mapped to assets or sub- asset name.For example, the mapper 122 of data object to assets can be all from assets Person's equipment 104 receives indicated assets or sub- asset name, and generates assets or sub- asset name arrives associated data object Each mapping.Then, the mapper 122 of data object to assets can be by mapping storage in assets permission database 148.

In addition, asset owner's equipment 104 can indicate the license of assets to be distributed to or sub- asset name.For example, being permitted It can may include read access, write-access, update access, delete access, update metadata access (for example, modification data pair The authorization of the attribute of elephant, such as format, bit rate, keyword, association performer, date created, shooting date etc.) and/or it is all As such, and it is associated with license to can specify which terminal user.As an example, terminal user, which can be, has been awarded visit Ask the user (for example, licensee, consumer, right holder etc.) of the license of certain data objects for Gong checking.Certain In embodiment, multiple licenses can be distributed for assets or sub- asset name.For example, first terminal user can be authorized to being mapped to The read access of the data object of assets or sub- asset name, and second terminal user can be authorized to being mapped to assets or son The data object of asset name reads and writees access.Assets permit manager 124 can receive by asset owner's equipment The license of 104 instructions, and license is mapped to indicated assets or sub- asset name.Then, assets permit manager 124 can With by mapping storage in assets permission database 148.Therefore, assets permission database 148 can store assets or sub- assets The mapping that mapping and assets or sub- asset name of the title to multiple data objects are permitted to one or more.Assets license count It will be more fully described below with reference to Fig. 3 according to the content in library 148.

Optionally, asset owner's equipment 104 can not indicate distribute to the license of assets or sub- asset name.? In this case, default license is distributed to assets or sub- asset name by assets permit manager 124, and default license is arrived The mapping storage of assets or sub- asset name is in assets permission database 148.

Assets permit manager 124 can be configured to that assets will be applied permissions in response to received request Or sub- asset name.For example, asset owner's equipment 104 can transmit addition or modify one or more asset names or son money Produce the request (for example, Application Programming Interface (API) is called) of the license of title.The request can identify one or more assets Or sub- asset name, and including the information newly permitted is described in detail.Identified one can be used in assets permit manager 124 Or multiple assets or sub- asset name and License Info modify the one or more moneys being stored in assets permission database 148 It produces or the license of sub- asset name is (for example, more new assets are to the mapping permitted and by the mapping storage of update in assets license count According in library 148).

Optionally, the request for adding or modifying the license of one or more asset names or sub- asset name includes time ginseng Number.Using time parameter, asset owner can specify the date and/or time of License Expiration.When requested License Expiration, The license of assets or sub- asset name can revert to previous license, can be changed to default license, or license may not Re-map assets or sub- asset name.

Assets permit manager 124 can be with automatic running application license selection assets or the rule of sub- asset name.Example Such as, rule can be defined on event occur when or setting time (for example, periodically) execute movement (for example, addition or Modify the license of assets or sub- asset name).Rule can the title based on assets or sub- assets (for example, asset owner sets Standby 104 titles provided) it is applied to assets or sub- assets.In addition, rule can be applied to data object, or it is mapped to phase The data object of different assets or sub- asset name is either mapped to the data object of assets or sub- asset name.For example, Rule can the format (for example, resolution ratio, file size, bit rate, playout length etc.) based on data object be applied to data Object.Event may include that the introducing of new assets or sub- asset name, existing license expire, are stored in asset database 144 In addition, modification and/or the deletion of one or more data objects and/or the like.The execution of rule can cause to provide The more new assets of permit manager 124 or sub- asset name is produced to permit to the mapping of license and by the mapping storage of update in assets In database 148.

The title and data object that lookup key database 146 can store data object are in asset database 144 Mapping between storage location.As described above, distributed objects memory block can have multiple subregions and use data object name Title is indexed.As shown in fig. 1, searching key database 146 is distributed objects memory block.Therefore, key data is searched Library 146 can have multiple subregions, and is indexed using the title for the data object being stored in asset database 144. The given associated data object with related names may cause above-mentioned performance bottleneck problem, and searching key generator 126 can be with The data object title of modification is generated, the data object title leads to different name prefixes and create initially to be owned by assets Mapping between the data object title of data object title and modification that person provides.Therefore, for asset owner, data pair The title of elephant remains unchanged.However, searching key database 146 instead based on change for the purpose for searching key database 146 The modification data object title of change and be indexed.

For example, searching key generator 126 can be configured as to be stored in each data pair in asset database 144 It is hashed as generating.Any known technology (such as SHA-256) can be used and generate hash.Searching key generator 126 can make With at least part of the file path of respective data object (for example, the position of the data object in identification asset database 144 Data object file path, including asset name, sub- asset name, data object title, file, sub-folder, son Catalogue, catalogue, subregion etc.) it is hashed to determine.Once generating hash, searching key generator 126 can dissipating generation Column are attached to the original title for the data object that asset owner provides as prefix, to form the data object title of modification. For example, if the hash that data object is named as the file path of " movie1file1 " and data object is " 7HG9 ", that The data object title of modification may be " 7HG9movie1file1 ".Even if associated data object may have related names And/or can store the similar position in asset database 144, the hashed value generated for associated data object can be difference (for example, the first character of the hashed value of first associated data object can be with the hash of second associated data object The first character of value is different).Indeed, it is possible to hashed value be generated, so that conflict is (for example, two continuous or nearly singular integral The read requests that (for example, request in mutual 2 requests) carries out same subregion) greatly reduce.Therefore, because searching close Key database 146 is by tree structured index, it is possible to which the data object title based on modification draws associated data object It assigns in different subregions.This can reduce asset retrieval server 108 or another equipment will continuously be read and/or write request A possibility that being sent to the same subregion for searching key database 146.Therefore, it is possible to reduce search 146 data of key database Retrieve the waiting time.

Optionally, searching key generator 126 can be used the data object title that other technologies generate modification.For example, Instead of generating hashed value and hashed value being attached to original data object title, lookup key generator 126 can overturn original The sequence of character in data object title.As another example, lookup key generator 126, which can be generated, is not based on data pair The unique identifier of the file path of elephant, and original data object title is replaced with unique identifier.As another example, it searches Generator 126 can randomly resequence (for example, for each data pair to the character in original data object title As being randomly determined rearrangement), and use the character of rearrangement as the data object title of modification.Key is searched to generate The other technologies that do not describe can be used to generate the data object title of modification as follows in device 126: so that having correlation The associated data object of data object title has difference early enough in the title of modification, so that searching key database The lookup of these associated data objects is randomized between the different subregions for searching key database 146 in 146.

Searching key generator 126 can be by the mapping between original data object title and the data object title of modification It is stored in the table searched in key database 146.Searching key generator 126 can also be by the position with corresponding data object The data object title of relevant modification generated, which is stored in, searches in key database 146, so that being repaired using generated The data object title changed come to search key database 146 be indexed.

Can based on the data object title of modification generated come to search key database 146 be indexed when, Index can be transparent to the user.For example, the generation of the data object title of modification may not influence asset owner's Data object naming convention.The title that asset owner's selection can be used in asset owner continues for data object to be stored in money It produces in file, sub-folder, catalogue in database 144 etc..The use of the data object title of modification can not change text The tissue and storage mode of part structure or data object in asset database 144.But it is requested when from asset database 144 When data object, which subregion that the data object title of modification can only control lookup key database 146 is accessed.Below The illustrated examples of lookup key database 146 are described with reference to Fig. 2.

Asset storage management device 128, which can be configured as, to be stored in asset database 144 from asset owner's equipment 104 Received data object.Asset storage management device 128 can be configured to the number being stored in asset database 144 Batch operation is executed according to object.For example, asset owner's equipment 104 can transmit asking for assets or sub- asset name list It asks (for example, API Calls), the assets or sub- asset name are mapped to specific end user and have license access (for example, reading Take, be written, update) data object.Asset storage management device 128 can to 148 queries asset of assets permission database or Sub- asset name list, and list is transmitted to asset owner's equipment 104 to show and/or store.Optionally, assets Permit manager 124 can retrieve list and send it to asset owner's equipment 104.As another example, asset store Manager 128 can receive the data object that will be mapped to assets or sub- asset name from one from asset owner's equipment 104 Accumulation layer is moved to the request (for example, API Calls) of another accumulation layer.In response to the request, asset storage management device 128 Can be with queries asset permission database 148 to identify the data object for being mapped to assets or sub- asset name, key is searched in inquiry Database 146 retrieves being known for the designated position in asset database 144 with the position of the identified data object of identification Other data object, and the data object identified is stored in again in the new accumulation layer of asset database 144.

As described above, associated data object can store in asset database 144 same file folder or catalogue in.But It is using the license mapping of assets described herein or sub- asset name to be different from that user is allowed to modify file license (then Applied to all data objects in file) conventional system because be stored in same file folder in associated data object Usually require different access authority.As illustrated examples, the file in asset database 144 be can store and the first money Produce relevant first data object and the second data object relevant to the first assets.First data object can be the first assets 720p version and the second data object can be the 1080p versions of the first assets.It can distribute and be permitted to first terminal user Can, the license authorizes first terminal user to the read access of the 720p and 1080p version of the first assets.It can be for second eventually End subscriber distribution license, the license are authorized second terminal user and are visited the reading of the 720p version of the first assets and other assets It asks, but the not access to the 1080p version of any access.It is realized in no asset store server 106 described herein In the case where technology, batch operation possibly can not be run in the above described manner to distribute to first terminal user and second terminal user License.Appended document folder may must be created with further subdivided data object, as needed for creation appended document folder or catalogue The additional position for reading and writing request and the expected data object as identifying given appended document folder or catalogue needed for The additional queries time and cause asset database 144 retrieve the waiting time increase.It is serviced by asset store described herein The technology that device 106 is realized can reduce the proliferation of file, to reduce the retrieval waiting time of asset database 144 and allow Run the ability of batch operation as described herein.

End user device 102 can request access to one or more data objects via asset retrieval server 108.Example Such as, end user device 102 can transmit the request of the first data object of access (for example, API to asset retrieval server 108 It calls).The request can indicate whether requested access is read access, write-access, update access, deletion accesses, Update metadata access and/or the like.Asset retrieval server 108 can be with queries asset permission database 148 to identify It is mapped to the assets or sub- assets of the first data object.Once it is determined that the assets or sub- assets of mapping, asset retrieval server 108 can queries asset permission database 148 to determine associated with end user device 102 user (or terminal user Equipment 102 itself) whether have in a manner of requested the assets of access map or sub- assets license.

If the user or end user device 102 do not have the license of access assets or sub- assets, asset retrieval Server 108 can send the notice of instruction denied access to end user device 102.Otherwise, if the user or terminal User equipment 102 has the license of access assets or sub- assets really, then asset retrieval server 108 can inquire lookup key Database 146 is to identify the position of the first data object in asset database 144.For example, asset retrieval server 108 can be with The table in key database 146 is searched in inquiry first, and original data object title is mapped to the data object of modification by the table Title, to identify the data object title of modification corresponding with the title of the first data object.Then, asset retrieval server Key database 146 is searched in the 108 data object name queries that modification can be used, to identify the file road of the first data object Diameter.Optionally, the inquiry of asset retrieval server 108 can make to search the identification of key database 146 and the first data object name Claim the data object title (for example, being stored in the table searched in key database 146) of corresponding modification and to assets The response of retrieval server 108 file path corresponding with the data object title of modification.

Using the received file path of institute, asset retrieval server 108 can retrieve the first number from asset database 144 End user device 102 is transferred to according to object, and by the first data object to meet request.Asset retrieval server 108 can be with This process is repeated to any amount of requested data object and any amount of end user device 102.

End user device 102 and asset owner's equipment 104 may include various calculating equipment, including individual Calculate equipment, terminal calculates equipment, lap-top computing devices, tablet computing device, electronic reader devices, mobile device (example Such as, mobile phone, media player, portable game equipment etc.), with network access and program executive capability wearable device (for example, " smartwatch " or " intelligent glasses "), wireless device, game console, entertainment systems, there is network to visit at set-top box It asks and the TV of program executive capability (for example, " smart television ") and various other electronic equipments and device.Each terminal is used Family equipment 102, which can execute, allows user request the browser application of certain data objects or only from asset retrieval server 108 Vertical application.Similarly, asset owner's equipment 104, which can execute, allows asset owner to add or modify license and/or management The browser application or independent utility of the storage of data object.

Asset store server 106 can be programmed or be otherwise configured to manage as described herein license and The computing system of data object storage.Asset store server 106 can be according to request, when event occurs, in data object When storing in asset database 144, when storing the data object in asset database 144 and being modified and/or its is any Automatically license is added or changed when combination.

The asset store server 106 and/or asset retrieval server 108 of Fig. 1 can be single calculating equipment, Huo Zheke To include logically or physically being grouped together multiple and different calculating equipment to operate collectively as server system, Such as computer server.The component of asset store server 106 and/or asset retrieval server 108 can be realized respectively Not needing software in the hardware (for example, server computing device with one or more ASIC) of application specific, or It is embodied as the combination of hardware and software.In addition, the module and group of asset store server 106 and/or asset retrieval server 108 Part can combine on a server computing device, or the group for individually separating or being divided on several server computing devices. In some embodiments, asset store server 106 and/or asset retrieval server 108 may include than shown in Fig. 1 More or fewer components.

In some embodiments, asset store server 106 and/or asset retrieval server 108 provide feature and Service can be implemented as via the consumable network service of communication network 110.In a further embodiment, asset store takes Business device 106 and/or asset retrieval server 108 are provided by calculating the one or more virtual machines realized in environment in trustship.Support Pipe calculates the computing resource that environment may include one or more fast supplies and release, and the computing resource may include meter Calculate, network and/or store equipment.Trustship calculates environment and is referred to as cloud computing environment.

Asset database 144, lookup key database 146 and/or assets permission database 148 can be located at asset store The outside of server 106 and/or asset retrieval server 108.For example, asset database 144, search key database 146 and/ Or assets permission database 148 can by individual system or server storage and management, and can via being directly connected to or Be indirectly connected with (for example, via network, such as network 110) and asset store server 106 and/or asset retrieval server 108 Communication.In other unshowned embodiments, asset database 144 searches key database 146 and/or assets license count It is located in asset store server 106 or asset retrieval server 108 according to library 148.

Search the sample table in key database

Fig. 2 illustrates the exemplary table searched in key database 146 for being stored in Fig. 1 according to an embodiment 200 and exemplary table 250.As shown in Fig. 2, table 200 is to store the data object name of original data object title and modification to be referred to as Between relationship table.For example, table 200 may include the data object file name header 202 for listing original data object title, with And list the data object key name header 204 of the data object title of modification.Row 220,222 and 224 can be retouched in table 200 Draw the entry for various data objects.As shown in table 200, original data object title can be " FILE1 ", " FILE2 " and "FILE3".In certain embodiments, " FILE1 ", " FILE2 " and " FILE3 ", which can be, is mapped to same assets or sub- assets Data object title.As described above, searching key generator 126, that hashed value can be generated is original to be attached to as prefix Data object title.Therefore, the data object title of modification can be " 4H56FILE1 ", " G765FILE2 " and " 1AENFILE3 ", wherein " 4H56 ", " G765 " and " 1AEN " is additional hashed value.

Table 250 can be the pass between the file path in the data object title and asset database 144 of storage modification The table of system.For example, table 250 may include the data object key name header 252, Yi Jilie for the data object title for listing modification The data object location header 254 of the file path of corresponding data object out.Row 260,262 and 264 can be described in table 250 For the entry of various data objects.Although row 260,262 and 264 is shown in Figure 2 for continuously, what this was merely to illustrate Purpose.Because each of additional hashed value is started with different characters, the data object title of modification will likely be fallen In the different subregions for searching key database 146.Therefore, even if asset retrieval server 108 attempts connected reference " FILE1 ", " FILE2 " and " FILE3 " can also be routed to lookup key to the read requests for searching key database 146 Different subregions in database 146.

Although table 200 and table 250 are depicted as searching individual table in key database 146, but this does not imply that limit System.For example, the content of table 200 and table 250 can be combined into the single table for being stored in and searching in key database 146.
