A control unit of a vehicle traveling data recorder acquires the position of a vehicle. Further, the control unit acquires a captured image generated by a camera which photographs the periphery of the vehicle. Then, if the acquired position of the vehicle belongs to an area where predetermined privacy processing is to be performed on an object included in the acquired captured image, the control unit stores, in a nonvolatile memory, data that is the captured image to which the privacy processing is applied, and if the acquired position of the vehicle does not belong to the area where the predetermined privacy processing is to be performed on the object included in the acquired captured image, the control unit stores the captured image in the nonvolatile memory.

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.

A device for documenting and encrypting a face to face personal meeting that includes a casing, a connecting unit that can communicate with external data storage device, a camera or microphone, an encryption subsystem, a decryption subsystem, and a personal key reader that is capable to identify personal keys of participants of the meeting. The device can encrypt the video that can be decrypted by using the personal keys of the participants. The device can save the encrypted video only in external storage device that communicates with the connecting unit while the camera shoots the video, and it is saved with information of the participants' identified personal keys. The decryption subsystem can decrypt the encrypted video when external storage device in which the encrypted video is saved communicates with the connecting unit and when the reader identifies the identified personal keys of the participants.

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.

Systems and methods for preventing image capture and exploitation by optically transmitting a disruptive effect to a digital imaging system. The disruptive effect interferes with the algorithms used to compress and analyze digital images and can be used to disable the imaging equipment or inject foreign code into the imaging system or image processing computer.

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.

A monitoring system of an embodiment includes an acquirer, an extractor, an encryption processor, and a generator. The acquirer is configured to acquire, from one or more monitoring cameras that capture an image of a work area in which presented information to be input is input to an input terminal, a captured image captured by the one or more monitoring cameras. The extractor is configured to extract the information to be input from the captured image acquired by the acquirer. The encryption processor is configured to encrypt the information to be input extracted by the extractor. The generator is configured to generate a replaced image in which the information to be input is made invisible, the replaced image comprising a partial image that displays information encrypted by the encryption processor at a position of the information to be input in the captured image acquired by the acquirer.

A method for cooperatively collecting video data from driving recorders includes steps of: by a driving recorder serving as a requesting device, broadcasting a video request; by another driving recorder serving as a cooperative device, generating a video file in response to receipt of the video request, encrypting the video file to result in an encrypted file, and transmitting the encrypted file to a video file server; by the video file server, decrypting the encrypted file to result in the video file, storing the video file, and sending a success notification of video data collection to a user device based on contact information contained in pre-stored registration data.

A terminal apparatus according to an embodiment includes a solid-state imaging element and a first communication unit. The solid-state imaging element includes an image sensor, an image processing unit, and an output interface. The image sensor converts received light into an image. The image processing unit detects a specific object in the image. The output interface outputs the image. The first communication unit transmits the image output from the output interface. The information processing apparatus includes a second communication unit and a processor. The processor receives an image transmitted from the terminal apparatus with the second communication unit. When the image received with the second communication unit is an image in which the image processing unit has detected a specific object, the processor performs mask processing of masking the specific object.
