摘要： Methods and systems described herein generate content that quickly cycles between different-colored frames at a rapid rate that may be imperceptible to human viewers. The human eye tends to blend nearby frames together, so that a human viewer will see a full color spectrum even though only a single color is displayed at any given time. The video display may repeatedly cycle between individual color frames, thus providing video content that appears normal to a human viewer. However, a video recording device may capture only some of the color frames. Therefore, the video recorded by video recording devices may include undesirable color flicker or other color artifacts, which may deter unauthorized copying.

摘要： A media playback method and device that relate to the field of computer technologies are provided. The method includes turning on a camera to detect the number of human eyes within a shooting range to determine an initial number of viewers when a user performs a media playback activity, detecting, at a set interval, the number of human eyes to determine a current number of viewers, and encrypting a playback image when the current number of viewers is greater than the initial number of viewers. The method is applicable when a user views information, such as a text, a picture, or a video, on a device such as a mobile phone terminal, a pad device, or a computer.

摘要： A resolution converter converts input image data to N types (N is a plural number) of image data having resolutions different with each other. A secret sharing unit performs secret sharing schemes so that the plurality of pieces of image data are respectively divided into n pieces (n is an integer equal to or more than N+1 and the same value in all of image data) of distributed data and the distributed data is reconstructed to original image data using k pieces (k is an integer equal to or more than 2 and equal to or less than n and different value for each piece of image data) among n pieces. A data combination unit generates n pieces of combination data by combining distributed data selected one by one so as not to overlap with each of resolutions and stores each piece of the combination data in different storages. As more pieces of distributed data are gathered, image data with higher resolutions can be reproduced and security for copyright, privacy, or the like can be secured in each piece of distributed data.

摘要： Systems and methods for obfuscating an image include creation of a plurality of obfuscated images from an original image, and successive display of the obfuscated images on a display device. Successive display of the images creates a representation of the original image perceivable by a user. Creation of the obfuscated images can include application of a set of masks to the original image, or to multiple starting images created by separating the original image based on characteristics, such as color. Portions of the original image or starting images corresponding to selected regions of the mask can be displayed, while portions corresponding to other regions can be concealed. Use of complementary masks results in the generation of complementary obfuscated images that, when combined, would form the original image. As a result, attempts to use a screen capture would only acquire the single obfuscated image displayed at the moment of the capture.
摘要翻译：用于模糊图像的系统和方法包括从原始图像创建多个混淆的图像，以及在显示设备上连续显示混淆的图像。图像的连续显示创建了用户可感知的原始图像的表示。混淆图像的创建可以包括将一组掩模应用于原始图像，或者通过基于诸如颜色的特征分离原始图像而创建的多个起始图像。可以显示与掩模的所选区域相对应的原始图像的部分或开始图像，而可以隐藏对应于其它区域的部分。互补掩模的使用导致产生互补的混淆图像，当组合时，将形成原始图像。因此，使用屏幕捕获的尝试将仅获取在捕获时显示的单个混淆图像。

摘要： Apparatus for identifying video content includes a scene detector to detect a plurality of consecutive scenes in the video content. The video content may include a video program and an advertisement contained within the video program. A signature generator determines a scene change signature for each of the plurality of consecutive scenes. A content identifier provides the plurality of scene change signatures to a comparator that compares the plurality of scene change signatures to a database having a plurality of video content items to identify the video program. The database includes an ordered plurality of previously determined scene change signatures for each item of video content in the database. The content identifier receives an identification of the video content from the comparator. The content identifier may further receive information related to a position of the plurality of scene change signatures within the ordered plurality of previously determined scene change signatures.

摘要： A recording medium enables special playback processing although part of the AV stream recorded therein is transformed. An AV stream, a first EP map, and a second EP map are recorded on the recording medium. In the AV stream, a part of the multiplexed stream including a first video stream and a second video stream is transformed. The first EP map indicates one or more entry points of the first video stream and the second EP map indicates one or more entry points of the second video stream. TS packets constituting I-pictures of the first video stream are indicated by every 4N-th entry point in the first EP map, and TS packets constituting I-pictures of the second video stream are indicated by the entry points whose presentation time is closest to the presentation time of any one of the every 4N-th entry point in the first EP map.

摘要： A method for identifying motion video/audio content, by means of comparing a video A to a registered video B so as to determine if they are originally the same as each other, wherein said method at least comprises the steps of extracting a fingerprint A from the video A; and searching from a fingerprint database for a pre-extracted and registered fingerprint B of the video B by means of comparison of fingerprint A with a sliding window of a possible fingerprint B, so as to determine that the video A is visually identical to the video B if a match is found. According to the present invention, the method for extracting a fingerprint data from video/audio signals facilitates the automatic identification, archiving and search of video content, and can be of without the need for human visual inspections.
