Patent number: 9077781Abstract: A request for real-time transfer protocol (RTP) data is sent from the caching proxy server to the server. The request may be for one specific type of data or multiple unrelated types of data. The server responds to the request indicating its support for the requested data. The caching proxy server determines whether to proceed or terminate the data transmission process based on the response provided by the server. If it is determined to proceed with the data transmission process, the caching proxy informs the server to send the requested data. The server sends the requested data in a body of a RTP packet. The RTP packet uses a RTP Meta-Info payload format, which includes a body and a field header. The field header includes fields to identify the streaming media data, and the field body includes the requested streaming media data.Type: GrantFiled: August 28, 2013Date of Patent: July 7, 2015Assignee: Apple Inc.Inventors: Denis Serenyi, Chris LeCroy

Patent number: 8938808Abstract: A method for using virtualization to implement information rights management. The method may include: 1) intercepting, at a virtualization module, a request from an application to access data; 2) querying an information-rights-management database for a virtualization policy associated with the access request; 3) receiving, at the virtualization module, the virtualization policy from the information-rights-management database; and 4) controlling access to the data by applying the virtualization policy to the access request in a manner that is transparent to the application. Various other methods, systems, and computer-readable media are also disclosed.Type: GrantFiled: March 1, 2010Date of Patent: January 20, 2015Assignee: Symantec CorporationInventors: Michael Spertus, Denis Serenyi, Brian Witten

Patent number: 8732269Abstract: The present invention provides several methods and apparatuses for transmitting multimedia data using streaming media protocols such as real-time transfer protocols (RTP) and real-time streaming protocols (RTSP) in a computer network environment. In one exemplary embodiment, a request for RTP data and its associated extension is sent from the caching proxy server to the server. The request may be for one specific type of data or multiple unrelated types of data. The server responds to the request indicating its support for the requested RTP extension data. The caching proxy server determines whether to proceed or terminate the data transmission process based on the response provided by the server. If it is determined to proceed with the data transmission process, the caching proxy informs the server to send the requested and supported RTP data. The server sends the requested data in a variable and extendible header format.Type: GrantFiled: December 7, 2011Date of Patent: May 20, 2014Assignee: Apple Inc.Inventors: Denis Serenyi, Chris LeCroy

Patent number: 8391494Abstract: A computer-implemented client-side method for protecting enterprise rights management keys from being compromised by untrusted client devices may comprise: 1) detecting a request on a client device to access protected data, 2) dynamically instantiating a processor-based secure virtual machine on the client device, 3) establishing a secure communication channel between the secure virtual machine and a policy server, 4) receiving, via the secure communication channel, a content key from the policy server, and then 5) decrypting, using the content key, the protected data using the secure virtual machine. Server-side methods, along with corresponding systems and computer-readable media, are also disclosed.Type: GrantFiled: February 26, 2009Date of Patent: March 5, 2013Assignee: Symantec CorporationInventor: Denis Serenyi

Patent number: 8312272Abstract: An authentication token management system securely manages an authentication token. Hardware based security extensions on a client are used to dynamically instantiate two dynamic secure virtual machines, a registration initiation module (RIM) and a registration completion module (RCM). A public key and a corresponding private key are generated, and the RIM seals the private key to the RCM. A request for an authentication token is signed by the hardware based security extensions and transmitted to the server. This request comprises at least the public key. In response, an authentication token encrypted with the public key is received. The RCM unseals the private key, and uses it to decrypt the received authentication token. The RCM then seals the authentication token to at least one additional dynamic secure virtual machine, which can use it to perform additional functionalities, such as data signing, encryption, generation and/or verification.Type: GrantFiled: June 26, 2009Date of Patent: November 13, 2012Assignee: Symantec CorporationInventors: Denis Serenyi, Zulfikar Ramzan

Patent number: 8261320Abstract: A computer-implemented method for securely managing access to data may comprise identifying a request to access data that is encrypted, the request being made within an insecure platform. The method may: determine that a requestor has a right to access the data, decrypt the data to provide decrypted data, and permit a secure platform to access the decrypted data. A computer-implemented method for securely managing access to data may comprise identifying a request to access data that is encrypted, the request being made within an insecure platform. They method may: submit the request to a policy server, receive permission from the policy server to access the data, decrypt the data to provide decrypted data, and permit a secure platform to access the decrypted data. A system for securely managing access to data may comprise: an authorization platform, an authentication module, a policy-enforcement module, and a cryptography module.Type: GrantFiled: June 30, 2008Date of Patent: September 4, 2012Assignee: Symantec CorporationInventors: Denis Serenyi, Brian Witten
