Abstract: A delivery and display system 10 prepares and delivers daily film rushes and/or film “cuts” (i.e., rough edits) in full motion video to users via the Internet in a collaborative application and display interface. The delivery and display system includes a system server 32, parsing and embedding software 34, an encryption system 36, and a collaborative display interface 70. The system server receives and stores digital media files 50 and AV log files 60. The parsing and embedding software 34 reads meta-data in an AV log file 60 and segments the digital media files 50, wherein the parsing and embedding software is capable of reading meta-data from both .FLX AV log files and .ALE AV log files. The parsing and embedding software 34 embeds meta-data from an AV log file 60 into the segmented digital media files 50. The encryption system 36 secures the digital media files 50, which have been embedded with meta-data from an AV log file 60, using digital rights management encryption.

Abstract: An imaging device (1) for imaging a subject and distributing the captured video. The privacy of the subject is adequately protected, and a required monitoring function is realized.

Abstract: When a channel which is not scrambled is selected, an error occurs in a digital stream processed in a CA processing module, which causes noises to occur in video and audio signals to be viewed. If a FAT channel to be received is a channel that is not CA-scrambled, a digital stream is directly supplied from a FAT demodulator to a demultiplexer without passing the digital stream through an external processing module. As a result, no noise occurs in video and audio signals to be viewed because the video and audio signals are not influenced by an error of the digital stream that occurs in the processing module.

Abstract: A method processes an input image securely. An input image I is acquired in a client. A set of m random images, H1, . . . , Hm, and a coefficient vector, a=[a1, . . . , am], are generated such that the input image I is I=?i=1m?iHj. The set of the random images is transferred to a server including a weak classifier. In the server, a set of m convolved random images H? are determined, such that {H1?=?1(H1*y}i,1m, where * is a convolution operator and ?1 is a first random pixel permutation. The set of convolved images is transferred to the client. In the client, a set of m permuted images I? is determined, such that I?=?2(?i=1m?iH1?), where ?2 is a second random pixel permutation. The set of permuted image is transferred to the server.

The watermarked signal comprises odd and even overlapped blocks where the watermark is contained in the even blocks. The method comprises, for each k-th even block, subtracting the two adjacent odd numbered blocks from the k-th even block of the watermarked signal to retrieve s*k(n), transforming s*k(n) into the frequency domain to generate Sk(f), calculating a phase of Sk(f) as ?(f) and a phase of Sk(f) as ?(f), calculating the difference ?(f) between ?(f) and ?(f), unwrapping ?(f) to obtain the phase modulation {tilde over (?)}k(f), and using a Viterbi search to retrieve the watermark embedded in {tilde over (?)}k(f).

Abstract: The present invention is suitable for use in a partial dual encrypted system. The present invention allows for two different decryption devices (e.g., an incumbent, or first, set-top and an overlay, or second, set-top) to be located in a single system having an incumbent encryption scheme and a second encryption scheme. Each set-top is designed to decrypt the first or second proprietary encryption schemes, respectively. In accordance with the present invention, the second set-top utilizes a novel program map table to ensure that the second set-top chooses correct elementary streams in the partial dual-encrypted stream (i.e., a combined stream including a first encrypted stream, a second encrypted stream, and a clear stream) for a desired program.

Abstract: Content material is protected with a variety of watermarking processes. Different subsets of the protected content material are submitted to different watermarking processes. At the rendering device, a watermark detector is configured to detect one or more different watermarks. Only if the particular watermark(s) that the rendering device is configured to detect is removed from the protected content material will the rendering device permit the rendering of the protected material. If the particular watermark(s) that the rendering device is configured to detect is unpredictable, or if the particular segment that is protected by a particular watermark is undetectable, a wholesale removal of specific watermarks from the watermarked material will neither be efficient nor economically viable.

Abstract: A motion-picture distributor (12) uses a computer system (22) to convert video signals from a master film (14) into serial video data (41) complying with DVD-Video standards. Further, the computer system (22) modifies the sequence of scene-data sets (42-1, 42-2, . . . ) constituting the data (41) and encrypts the data for each scene-data set, thus producing encrypted non-serial video data (45). The data (45) are separated into DVD-ROMs (15-1, 15-2, . . . ), for distribution purposes. A theater (13) then uses a serialization apparatus (51) to read the data (45) from the DVD-ROMs (15-1, 15-2, . . . ), and sorts the scene-data sets in a correct sequence, thus producing encrypted serial video data (80). A motion picture projector (52) decrypts the data (80), thereby preparing the data (41). The data (41) are played back to view a movie. On the other hand, a movie distributor (12) may distribute the DVD-ROMs in a separated manner.

Abstract: A method and an apparatus for error resilient, digital image scrambling are disclosed. Error resilience scrambling is produced by shuffling transform coefficients between arrays of coefficients arranged along an axis substantially orthogonal to the axis along which packetization of the coefficients proceeds. Scrambling transform coefficients requires a reasonable level of processing resources and has minimal impact on the efficiency of the compression process. Shuffling can be performed in a number of ways to provide good access security and a variety of security. Scrambling the image data in a direction substantially orthogonal to the direction of packetization of the transform coefficients distributes any transmission error in the image reducing the effects of data error or loss on the displayed image.

Abstract: A method and apparatus of encrypting optical images using binarization or phase only information is presented with a number of ways to secure the image also being provided. An image to be encrypted is first multiplied by a random phase function. The Fourier transform of the product of the image and the random phase function is then multiplied by another random phase function in the Fourier (or Fresnel) domain. Taking the inverse Fourier (or Fresnel) transform, an encrypted image in the output plane is obtained. Alternatively, the image to be encrypted can be phase encoded and then encrypted to provide an extra level or security. The image can be secured using one key in the Fourier or Fresnel domain followed by phase extraction. This encrypted image may then binarized, which may include binarizing the phase-only part of the encrypted image. The use of binarization enables ease of implementation and data compression while still providing recovery of images having good quality.

Abstract: A method, system, computer program product, and method of doing business by digitally notarizing a collection of data streams, thereby improving security of the contents of the data streams. Preferably, public key cryptography is used, wherein the collection of data streams is digitally signed (i.e. notarized) using a private cryptographic key of a digital notary, such that an associated public cryptographic key can be used to verify the authenticity and integrity of the collection of data streams. One or more components which are involved in creating the data streams are preferably authenticated, and a unique identifier of each such component is included within cryptographically-protected information that is provided for the digital notarization. The authenticated identities of the components can therefore be determined from the digital notarization.

Abstract: An image indicating a copyright and its related information are set through a setting input means and those settings are stored in a related information storing means in advance. Registration image data is recorded in a detachable registration image data recording medium in advance. When an arbitrary image signal is generated by an image generating means, an image combining control means receives the generated image signal and also receives, via a registration image data input means, the registration image data stored in the registration image data recording medium. Further, the image combining control means generates a registration image signal by referring to the setting information and combines it with the arbitrary image signal. In this state, if no corresponding registration image data exists in the registration image data recording medium, image signal combining is not performed.

Abstract: An image authentication system utilizes a coded version of a digital image signature and embeds that information into a transform representation of the image. A digital image signature preferably is extracted from the image data. That signature is coded so that the signature is not immediately recognizable. The coded information is embedded into high frequency coefficients in a transform representation of the image. The contents of the high frequency coefficients of a received or later accessed signal can then be deciphered and compared to the signature determined directly from the image to authenticate the integrity of the signal.

Abstract: A method and apparatus for enabling background caching of encrypted programming data on a storage medium for later playback in a digital video recorder (DVR) system. A set-top box (STB) equipped with a DVR searches a program guide for upcoming pay-per-view (PPV) events.

Abstract: A method for encrypting programming in which a controlled number of unintended recipients of a broadcast are allowed to view a program so that a set of encryption keys can be found which enables a broadcaster to more quickly broadcast the program to its intended paying recipients than conventional encryption methods which only allow programs to be viewed by its intended recipients. To find the set of keys, a broadcaster first determines an acceptable f-ratio of a total number of viewers of the broadcast program to a number of intended viewers in an identified target set who paid to receive the program. The target set of viewers is included in the total number of viewers. The broadcaster then constructs an f-redundant establishment key allocation set from which the establishment keys for encrypting the program are selected.
