Embodiment
Because the development of mobile communication technology, increasing user brings into use the online use digital publishing rights of mobile terminal device content, and have now in the mobile communication system about in the agreement of DRM, not to the method for periodicity time period binding authority, for example: the 19:00 of every day can't satisfy the demand of user's subscription period time period authority to 19:30.
The user is meant each effective use in the date that the user distributed according to the fixed cycle to the periodicity consumption demand of digital content, regular time, section watched the online digital rights information of certain cannel broadcast, technical solution of the present invention is by the restrictive condition for the increase periodicity time period among the existing permission object RO, and in DRM Agent, increase the logical process of controlling user's rights of using according to the restrictive condition of periodicity time period, thereby satisfy the periodicity consumption demand of user to digital content.
Periodically time period information comprises effective use date and time information and each effective effective storage life segment information that uses in the date of periodic distribution, wherein: the effective storage life section is a fixed value, when the user effectively uses time point of date consumption digital publishing rights content to drop in the time range that the time period limits at each, the user has effective consumption rights constantly at this, otherwise the user does not have consumption power constantly at this.
In RO, by zero-time and concluding time two parameter items time period information is described, by the following parameters item effective use date and time information of periodic distribution is described, generally be unit: start time date of expiration with the sky; Concluding time date of expiration; Period type; Appointed day in each cycle; With table 1 is the example explanation:
Table 1. is time period information description table periodically
The broadcasting channel identification information that generally also comprises online copyright information in the table 1, by the description of table 1, the user has the right to watch that the time of playing online copyright information channel is between the 2005-8-1 to 2005-9-21, every day 19:00:00 to 19:45:00.
The parameter value of each parameter item in the interface input table 1 that the user can provide by RI, set the use-pattern that needs flexibly, also can in predefined each description list of RI, directly specify one, DRM Agent is carried at periodicity time period information and sends to RI in the RO request message, RI generates RO according to the periodicity time period information of user's request, and being carried at the DRMAgent that sends to user terminal in the RO response message, DRM Agent is again according to periodicity time period information Control user's rights of using.
Wherein, period type can or year be divided with sky, week, the moon, if the user selects to divide with week, then the appointed day can be any 1 day of Monday to Sunday; If the user selects to divide by the moon, then the appointed day can be No. 1 to any 1 day between the end of month, at this moment, the fate that it should be noted that every month is inconsistent, if effectively life cycle has comprised February, and the user specifies every month No. 30 uses, then illegal appointment may be considered to,, a plurality of appointed day options can be comprised with weekly or when dividing the cycle in every month; If the user selects to divide the cycle with year, then need further subitem, for example specify month earlier, again appointed day etc.
Can also be set as follows the acquiescence mode, giving tacit consent to every day when for example not importing period type in the table 1 is the appointed day, when not importing zero-time and concluding time, is defaulted as in the use date of appointment whole day and uses.
Can also set a plurality of time periods, limit the different service times that each effectively uses the date respectively, for example: select 19:00:00 to 19:45:00 to watch news, select 20:30:00 to 22:00:00 to watch prime time TV play etc.
The concrete expression method of time or date is a lot, not in order to limit protection domain of the present invention.
Be a embodiment below with copyright description language performance periodicity time period restrictive condition, in the copyright description language, the element of a newly-increased expression authority restrictive condition is as＜period〉conduct＜constraint〉daughter element of element, can only in the periodic time period, use to limit online copyright digital content (as Streaming Media).Corresponding RO segment can be described below for example:
<o-ex:permission>
<o-dd:execute>
<o-ex:constraint>
<o-dd:datetime>
<o-dd:start>2005-01-01T00:00:00Z</o-dd:start>
