摘要： Disclosed is, among other things, a method for distributing content items to authorized users. The method comprising: a content owner device (190), COD, obtaining a first content item (196a); the COD (190) obtaining a first tag associated with the first content item (196a); the COD (190) obtaining a first content key, CK1, for said first content item (196a); the COD (190) encrypting the first content item (196a) using CK1, thereby producing a first encrypted content item; the COD (190) using at least the first tag and a key derivation function, KDF, to derive a first derived key, DK1; the COD (190) encrypting CK1 using the DK1, thereby producing a first encrypted content key, ECK1; and the COD (190) transmitting information to a content server (108), the information comprising: the first encrypted content item and the first tag.

摘要： An approach is provided for determining a request from a user for an access to at least one user group. The at least one user group is associated with at least one reference location. Consequently, the point of interest platform determines location information associated with the user and/or the device associated with the user. Subsequently, the point of interest platform causes, at least in part, a granting of the access to the user group if the location information indicates that the user and/or the device associated with the user is within a predetermined proximity of the reference location.

摘要： Systems and methods for secure content distribution, including a content server, a rights management server, a residential gateway communicating with the content server and the rights management server via a network, and a playback device communicating with the residential gateway via a local network. The residential gateway receives protected content from the content server. The playback device requests access to the protected content from the residential gateway. The residential gateway requests access to the protected content from the rights management server by including information uniquely identifying the playback device. The rights management server provides access information to the residential gateway when the access information satisfies predetermined criterion for playback devices associated with the residential gateway. The residential gateway decrypts the protected content using the access information and encrypts the decrypted content for distribution to the playback device via a secure link formed between the residential gateway and the playback device.

摘要： This invention relates to a method (100) for creating, on a device (200), an authorized domain (102) for sharing a right (103) of a content item (104) between a first person (105) and a second person (106). The method (100) alleviates the hassle of having end-users managing authorized domains. If the first person is bound (107) to the right (103), and the device is bound (108) to the first person (105), the device (200) grants (110) the second person (106) the right (103) in response to the device (200) associating (109) to the second person (106).
