Embodiment
The present invention increases the element that is used to describe consumption status information in right expression language (REL); And, quote attribute (idref) by authority element (permission/constraint) increase identity property (id) and sign for right expression language (REL), realize the coupling of consumption status information and original authority information.
The original authority information of the consumption class authority of described consumption status information indication permission is by the state after consuming, with OMA (Open Mobile Alliance, Open Mobile Alliance) DRM is an example, described consumption status information can be by increasing state information＜stateInfo in REL〉unit usually describes, this element can be defined in the message of transmitting permission RO (Rights Object), also can be defined among the permission RO.
For example, definition consumption status information field in the message of transmitting the authority relevant information:
<element?name＝″stateInfo″type＝″o-ex:constraintType″minOccurs＝″0″maxOccurs＝″unbounded″/>
Perhaps, definition is used to write down the element of consumption status information in permission RO, wherein comprise one or more limit entry, and the sign of each limit entry (as number of times count/ time interval interval etc.) is quoted attribute idref and is indicated limit entry in the associated original authority information of limit entry in this consumption status information.Be defined as follows:
<！ELEMENT?oma-dd:stateInfo(o-dd:count？，oma-dd:timed-count？，o-dd:datetime？，o-dd:accumulated？)>
Perhaps, the element that is used for writing down consumption status information comprises restriction＜constraint〉daughter element, by＜constraint〉daughter element advances one one and comprises concrete limit entry.
<！ELEMENT?oma-dd:stateInfo(o-ex:constraint？)>
With limit entry count, interval is example, is respectively its definition identity property id and sign and quotes attribute idref; Described identity property id is used for identifying an original authority information item uniquely a licence inside, and described sign is quoted attribute idref and is used for quoting corresponding original authority information item at the consumption status item of information.In the consumption status item of information＜count value can represent the number of times that consumed, also can represent remaining number of times, specifically can define voluntarily, also can be by＜stateInfo by different application scenarioss〉the attribute decision.
＜! ATTLIST o-dd:count o-ex:id ID#IMPLIED〉// identity property id is suitable for＜count father element＜constraint belong to the situation of original authority information, be used for identifying uniquely this original authority information item.
＜! ATTLIST o-dd:count o-ex:idref IDREF #IMPLIED〉// sign quotes attribute idref and is suitable for＜count father element＜constraint belong to the situation of consumption status information, be used for consumption status information is associated with corresponding original authority information.
The time interval＜interval in the consumption status item of information〉value represent the consumption digital content for the first time from the user, the time span of sustainable consumption.As＜interval〉10h＜/interval〉represent that consuming this content for the first time from the user picks up counting, within 10 hours, can use, surpass 10 hours and then can be under an embargo.Therefore, at record＜interval〉consumption status the time, also can change into time period datetime and come record.
＜! ATTLIST o-dd:interval o-ex:id ID #IMPLIED〉// identity property id is suitable for＜interval father element＜constraint belong to the situation of original authority information, be used for identifying uniquely this original authority information item.
＜! ATTLIST o-dd:datetime o-ex:idref IDREF #IMPLIED〉// sign quotes attribute idref and is suitable for＜datetime father element＜constraint belong to the situation of consumption status information, be used for consumption status information is associated with corresponding original authority information.
Because the consumption status information that write down both can have been represented current available authority, also can represent the authority that consumed therefore, can show its implication further for attribute of stateInfo increase, as:
＜! ATTLIST oma-dd:stateInfo oma-ex:mode#IMPLIED〉// be used for representing to be " remaining " or " consuming "
The transmission of authority relevant information can realize by transfer (move), the copy (copy) of permission, the modes such as (share) of sharing.Destination entity after obtaining described authority relevant information, according to " original authority information item-consumption status item of information " to determining local available authority relevant information, and according to the consumption of this authority relevant information control to digital content.Consult shown in Figure 1ly, consumption status item of information a represents the state after original authority information item 1 is by consumption, is associated by " identifying=001 " between them; Consumption status item of information b represents that original authority information item 3 by the state after consuming, is associated by " sign=003 " between them.
When being given in the transmission of carrying out the authority relevant information below, an instantiation of authority relevant information is described.This example shows, comprises the authority of a broadcast (play) in the initial licence that obtains of user, can only play at most 10 times, and the system that plays the digital content of this licence correspondence is necessary for XYZ v1.0 version; And up to the present, 10 times broadcast right has been consumed 2 times, and promptly the active user also has the broadcast right of 8 these contents, and the restriction Play System is necessary for XYZ v1.0 version.
……
<permission>
<play>
<constraint>
<count?id＝“c1”>10</count>
<system>
<context>
<version>1.0</version>
<uid>XYZ</uid>
</context>
</system>
</constraint>
</play>
</permission>
……
……
<stateInfo>
<count?idref＝“c1”>2</count>
</stateInfo>
……
And for example, the user obtains one at first and has the broadcast authority, and interval is restricted to 10 hours licence.It is at 14:00 on March 1st, 2006 that the user plays corresponding content for the first time, definition according to interval, this user can only play this content before the 24:00 on March 1st, 2006 at most, and having write down the termination time in the therefore corresponding consumption status information is 2006-03-01T24:00:00Z.
……
<permission>
<play>
<constraint>
<interval?id＝“i1”>10h</interval>
</constraint>
</play>
</permission>
……
……
<stateInfo>
<datetime?idref＝“i1”>
<end>2006-03-01T24:00:00Z</end>
</datetime>
</stateInfo>
……
Similarly, can quote attribute idref for other limit entry increase identity property id and sign, as: timed-count, accumulated etc.; Also can be for each right item is provided with id, idref attribute, as under right elements such as play, print, execute, defining id, idref attribute respectively.
In above-mentioned processing procedure, each authority items is to identify and quote by id, idref attribute, here the purpose that also ID, IDREF can be reached sign and quote as the daughter element of each authority items.As:
<！ELEMENT?o-dd:count(oma-dd:id，oma-dd:idref)>
Because one＜constraint〉below generally a plurality of identical limit entry can not appear, therefore, except identifying concrete limit entry, id also can be used for sign＜constraint〉element, also can reach the purpose of unique identification limit entry.As:
<permission>
<play>
<constraint?id＝“001”>
<count>10</count>
<system>
<context>
<version>1.0</version>
<uid>XYZ</uid>
</context>
</system>
</constraint>
</play>
</permission>
……
……
<stateInfo?idref＝“001”>
<count>2</count>
</stateInfo>
……
In above-mentioned processing procedure, because idref can only be used for internal reference, therefore to have only when being recorded in original authority information and consumption status information in the identical file (as Rights Object), the mode that just can use id, idref is with both associations.If original authority information and consumption status unpack record, then need to define other element or attribute with both associations, for example use identity property id with both associations respectively, and with＜constraint〉element is example, definition id attribute.
＜! ATTLIST o-ex:constraint o-ex:id ID #IMPLIED〉// as＜count father element＜constraint when being arranged in raw information, id be used for RO identify uniquely should＜cosntraint element, and with in " stateInfo " and the corresponding original authority information＜constraint be associated.
Definition consumption status information field in the message of transmitting the authority relevant information:
<element?name＝″stateInfo″type＝″o-ex:constraintType″minOccurs＝″0″maxOccurs＝″unbounded″/>//
By＜constraint〉with the id attribute of stateInfo that both are related, as:
<permission>
<play>
<constraint?id＝“001”>
<count>10</count>
<system>
<context>
<version>1.0</version>
<uid>XYZ</uid>
</context>
</system>
</constraint>
</play>
</permission>
……
……
<stateInfo?id＝“001”>
<count>2</count>
</stateInfo>
……
