Abstract:
A system and method for protecting user privacy in multimedia uploaded to Internet sites. Briefly stated, the method includes receiving, by a server hosting an Internet privacy protection service, a media item of a subscriber of the service from a social networking service. The media item is encrypted using Digital Rights Management techniques. Policy determining who can view the media item is generated. The encrypted media item is securely stored in a cloud storage network. Storage information, including a URL of the secure storage location for the encrypted media item, is received by the Internet privacy protection service from the cloud storage network. The Internet privacy protection service generates a proxy image by encoding the URL into the proxy image using a bar code. The Internet privacy protection service uploads the proxy image to the subscriber's social networking service account on the social networking service.
Abstract:
The present disclosure is directed to content protection for Data as a Service (DaaS). A device may receive encrypted data from a content provider via DaaS, the encrypted data comprising at least content for presentation on the device. For example, the content provider may utilize a secure multiplex transform (SMT) module in a trusted execution environment (TEE) module to generate encoded data from the content and digital rights management (DRM) data and to generate the encrypted data from the encoded data. The device may also comprise a TEE module including a secure demultiplex transform (SDT) module to decrypt the encoded data from the encrypted data and to decode the content and DRM data from the encoded data. The SMT and SDT modules may interact via a secure communication session to validate security, distribute decryption key(s), etc. In one embodiment, a trust broker may perform TEE module validation and key distribution.
