Abstract
A method and device for authentication of subscription based digital media receivers, SB DMRs are disclosed. According to one aspect, an SB DMR includes a memory, a radio, and a processor. The memory is configured to store an identification of each of at least one other SB DMR sharing a common subscription to a digital media service. The radio is configured to receive the identification of each of the at least one other SB DMR. The processor is configured to authenticate the SB DMR based on the received identifications to determine if the SB DMR is part of a group of SB DMRs sharing a common subscription.
Claims18
A subscription-based digital media receiver, SB DMR, comprising:
- a memory configured to store an identification of each of at least one other SB DMR sharing a common subscription to a digital media service, the identified at least one other SB DMR being pre-determined to be within a proximity to the SB DMR when the SB DMR is within a specified area;
- a communication interface configured to:
- receive an identification of one of the at least one other SB DMR;
- and
- a processor configured to:
- authenticate the SB DMR, the SB DMR being authenticated only if a received identification is of the at least one other SB DMR pre-determined to be within the proximity to the SB DMR when the SB DMR is within the specified area, the authentication indicating that the SB DMR is within the specified area and is therefore allowed to receive content.
A method of restricting use of a digital media service to a group of subscription-based digital media receivers, SB DMRs, of a subscriber, the method comprising:
- receiving, by a first SB DMR, from at least one of the other SB DMR in the group an identification of the at least one other SB DMR when the at least one other SB DMR is within proximity to the first SB DMR;
- and
- attempting to authenticate the first SB DMR when an identification of another SB DMR of the group is received by the first SB DMR, the first SB DMR being authenticated only if the received identification is of at least one other SB DMR pre-determined to be within proximity to the first SB DMR when the first SB DMR is within a specified area, the authentication indicating that the first SB DMR is within the specified area and is therefore allowed to receive content.
A method of restricting availability of a digital media service to a group of subscription-based digital media receivers, SB DMRs, each SB DMR having a unique identifier, the method comprising:
- receiving, by a first SB DMR, from at least one other SB DMR in the group an identification of the at least one other SB DMR when the at least one other SB DMR is within proximity to the first SB DMR;
- attempting to authenticate the first SB DMR based on the received at least one identification, the authentication of the first one of the SB DMRs being successful only if the received at least one identification is of at least one other SB DMR predetermined to be within proximity to the first SB DMR when the first SB DMR is within a specified area, the authentication indicating that the first SB DMR is within the specified area and is therefore allowed to receive content.
