Title: Selective and renewable encryption for secure distribution of video on-demand
Inventor: COLLIGAN MICHAEL ROBERT
IPC: H04N21/2347
Filed: 2000-04-05
Granted: 2012-06-05
Abstract: Selective encryption is provided in a process which includes: determining whether a predetermined criterion is satisfied; setting a selective encryption status field (1402) if the predetermined criterion is satisfied; and encrypting an unencrypted payload to generate an encrypted payload, and constructing a packet with the encrypted payload (1406), if the predetermined criterion is satisfied. The predetermined criterion may be one of several criteria, each of which reduce the required amount of encryption and decryption while maintaining a high level of security. Renewable encryption is provided in a process which includes: copying a first encrypted digital video program from a remote server to a video source; decrypting the first encrypted digital video program using a first key to generate an unencrypted digital video program; encrypting the unencrypted digital video program using a second key to generate a second encrypted digital video program; transmitting the second encrypted digital video program from the video source to the remote server; and deleting the first encrypted digital video program from the remote server.

Granted: 2014-09-09
Abstract: A method and apparatus for securing location information and access control using the location information are disclosed. A wireless transmit/receive unit (WTRU) includes a location sensing entity and a subscriber identity module (SIM). The location sensing entity generates location information of the WTRU and the location information is embedded in a message in an SIM. A trusted processing module in the WTRU verifies integrity of the location information. The trusted processing module may be on the SIM. The location information may be physical location information or contextual location-related information. The trusted processing module is configured to cryptographically secure and bind the location information to the WTRU, and verify trust metrics of an external entity prior to granting an access to the location information or accepting information from the external entity. The trusted processing module may be a trusted computing group (TCG) trusted platform module (TPM) or mobile trusted module (MTM). The location information may be used for an authentication purpose or access control. The location information may be combined with time information.

Abstract: Provided herein are methods for the treatment of liver cancer. These methods encompass the administration of a compound comprising a modified oligonucleotide, wherein the modified oligonucleotide is targeted to a miRNA. Also provided herein are compositions for the treatment of liver cancer. Such compositions include compounds comprising a modified oligonucleotide, wherein the modified oligonucleotide is targeted to a miRNA.  Certain miRNAs have been identified as overexpressed in liver cancer, such as, for example, hepatocellular carcinoma, and are thus selected for targeting by modified oligonucleotides.  Further, certain miRNAs have been identified as overexpressed in hepatocellular carcinoma cells exposed to dioxin, and are thus selected for targeting by modified oligonucleotides. Antisense inhibition of certain of these miRNAs has been found to inhibit cell proliferation and induce apoptosis.

Abstract: Binaural rendering a multi-channel audio signal into a binaural output signal (24) is described. The multi-channel audio signal comprises a stereo downmix signal (18) into which a plurality of audio signals are downmixed, and side information. Based on a first rendering prescription, a preliminary binaural signal (54) is computed from the first and second channels of the stereo downmix signal (18). A  decorrelated signal (X~k) is generated as an perceptual equivalent to a mono downmix (58) of the first and second channels of the stereo downmix signal (18) being, however, decorrelated to the mono downmix (58). Depending on a second rendering prescription (P2l,m), a corrective binaural signal (64) is computed from the decorrelated signal (62) and the preliminary binaural signal (54) is mixed with the corrective binaural signal (64) to obtain the binaural output signal (24).
