Abstract
Method and system for securely sharing content in real-time systems over heterogeneous networks. Cryptographic mechanisms of the content are used to protect the confidentiality and the integrity of the content. The confidentiality/integrity protection may be performed either before storing the content on the content server (i.e., pre-encryption), or by the content server while the content is being sent (i.e., real-time encryption).
Claims27
A method for sharing content between a first party and a second party in a secure communication session, comprising:
- storing a content of the first party on a personal content server;
- distributing access information for the content from the first party to the second party, the access information allowing the second party to access the content;
- presenting the access information of the second party to the personal content server;
- verifying the access information from the second party in the personal content server;
- and
- processing the content for distribution to the second party upon verification of the access information.
A telecommunication system wherein content may be shared between a first party and a second party in a secure manner, comprising:
- a first party terminal;
- a second party terminal connected to the first party terminal in a secure communication session, the first party terminal configured to distribute access information for a content to the second party, the access information allowing the second party to access the content;
- a personal content server connected to the first and second party terminals and storing a content of the first party thereon, the personal content server configured to verify the access information when it is presented to the personal content server by the second party, and to process the content for distribution to the second party upon verification of the access information.
A network node for facilitating secure sharing of content between a first party and a second party, said network node normally accessible by the first party only, comprising:
- means for establishing a secure connection to the terminals of the first and second parties;
- means for storing a content of the first party;
- means for issuing access authorization to the second party terminal;
- means for receiving a request to access the content using the access authorization from the second party terminal;
- means for verifying the received access authorization;
- and
- means for distributing the content in a secure manner to the second party terminal upon verification of the access authorization.
