Abstract
Systems and methods are for content security may comprise transmitting a request for authorization to access secured content. A content key for the secured content may be received and stored to a restricted region of a memory. A device security module may have access to the restricted region and may decrypt, based on satisfaction of a use condition and using the content key, the secured content. An encryption key associated with a secure media system authorized to access the secured content may be received. The device security module may encrypt, using the encryption key, the secured content and route the secured content to the secure media system.
Claims20
A method comprising:
- receiving, by a computing device and based on a request for authorization for a first media system to access secured content, an indication of a permission for the computing device to access the secured content;
- decrypting, by a device security module of the computing device and based on the indication of the permission, the secured content using a content key, wherein the content key is stored at the device security module;
- causing the secured content to be presented on the first media system;
- encrypting, by the device security module and using an encryption key associated with a second media system, the secured content;
- and
- sending, by the device security module and to the second media system, the encrypted secured content for presentation on the second media system.
A non-transitory computer-readable medium storing instructions that, when executed, cause:
- receiving, by a computing device and based on a request for authorization for a first media system to access secured content, an indication of a permission for the computing device to access the secured content;
- decrypting, by a device security module of the computing device and based on the indication of the permission, the secured content using a content key, wherein the content key is stored at the device security module;
- causing the secured content to be presented on the first media system;
- encrypting, by the device security module and using an encryption key associated with a second media system, the secured content;
- and
- sending, by the device security module and to the second media system, the encrypted secured content for presentation on the second media system.
A system comprising:
- an authorization device;
- and
- a computing device configured to:
- receive, from the authorization device and based on a request for authorization for a first media system to access secured content, an indication of a permission for the computing device to access the secured content;
- decrypt, by a device security module of the computing device and based on the indication of the permission, the secured content using a content key, wherein the content key is stored at the device security module;
- cause the secured content to be presented on the first media system;
- encrypt, by the device security module and using an encryption key associated with a second media system, the secured content;
- and
- send, by the device security module and to the second media system, the encrypted secured content for presentation on the second media system.
