  • System and method for securely transmitting video over a network
    Patent number: 8837598
    Abstract: A method comprises receiving a bit stream associated with at least one video image, wherein the bit stream comprises at least one macroblock header and a plurality of macroblocks. The method continues by encrypting the at least one macroblock header. The method concludes by transmitting the bit stream such that the at least one macroblock header is in an encrypted format and at least one macroblock is in an unencrypted format.

  • System and Method for Encryption and Secure Transmission of Compressed Media
    Publication number: 20090169001
    Abstract: A method comprises receiving a bit sequence associated with at least one file, the bit sequence comprising payload data in a compressed format and characterization data that maps the compressed format of the payload data. The method continues by encrypting the characterization data that maps the compressed format of the payload data. The method concludes by transmitting the bit sequence such that the characterization data is encrypted and at least a portion of the payload data is unencrypted.
