An information output device includes: a first output unit that outputs acquired information acquired by a sensor; and a second output unit that converts personal information included in the acquired information into attribute information from which identification of an individual is impossible, and outputs the attribute information.

Provided are a privacy protection method for a transmitting end and a receiving end, an electronic device, and a computer-readable storage medium. The method includes acquiring an initial image, acquiring an area to be scrambled in the initial image, performing backup and scrambling for the initial image based on the area to be scrambled to obtain a scrambled image and backup information, encrypting the backup information to obtain an encrypted result, and transmitting the scrambled image and the encrypted result.

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.

An information output device includes: a first output unit that outputs acquired information acquired by a sensor; and a second output unit that converts personal information included in the acquired information into attribute information from which identification of an individual is impossible, and outputs the attribute information.

Image encryption in which excessive concealment of information is prevented while reduction in cost is achieved by eliminating a need for a receiving side of an image to take measures against leakage of personal information is realized. In one example, a sensor device includes an array sensor with pixels having a light receiving element of visible or invisible light. A detector detects a target area on the basis of an image signal obtained by the array sensor. The target area in the image signal is encrypted on the basis of information from the detector. Thus, encryption of the image signal can be performed in the image sensor at least to the extent that no individual can be identified. Also, depending on a decryption key on a receiving side of the image, a part of the content of the image can be visually recognized while personal information is concealed.

A media client device, including a memory and capable of processing Quadrature Amplitude Modulation (QAM) channels and IP channels, may receive a recording request to record content on an Internet Protocol (IP) channel. The media client device may provide, to a first device, a source Universal Resource Locator (URL) corresponding to the content, and receive, from the first device, encrypted content (e.g., an encrypted version of the content). The media client device may store, in the memory, the encrypted content, and provide, to a second device, information regarding the encrypted content to permit the second device to generate and store a license and a key. The media client device may receive a playback request to play the content, and obtain, from the second device, the license and the key. The media client device may decrypt, using the license and the key, the stored, encrypted content to obtain the content.

Apparatus and methods for encrypting captured media. In one embodiment, the method includes capturing media data via use of a lens of an image capture apparatus; obtaining a number used only once (NONCE) value from the captured media data; obtaining an encryption key for use in encryption of the captured media data; using the obtained NONCE value and the obtained encryption key for encrypting the captured media data; and storing the encrypted media data. In some variants, the media is encrypted prior to storage, thereby obviating any instances in which the captured media data resides in a wholly unencrypted instance. Apparatus and methods for decrypting encrypted captured media are also disclosed.

A visible wearable device to be worn by a user having one or more housings configured to be worn by the user, one or more cameras disposed in the housing and configured to record one or more visual scenes and output one or more visual data files, one or more power sources for powering the one or more cameras, and one or more transmitters transmitting the one or more visual data files to a location remote from the user. The stored data to be released only in response to an order of a court of competent jurisdiction.

An information output device includes: a first output unit that outputs acquired information acquired by a sensor; and a second output unit that converts personal information included in the acquired information into attribute information from which identification of an individual is impossible, and outputs the attribute information.

A recording system that is designed to record a personal meeting between a service provider and a key-holder participant that includes an encryption subsystem, a recording means and a memory means. The recording means films the personal meeting and streams it to the encryption subsystem that encrypts the film and sends it to the memory means. The encryption subsystem includes an encryption means, a decryption means and a key reader. The encrypted film can be decrypted only by using a personal key of the key-holder participant.
