Problems solved by technology

The problem with this solution may be that in some cases the video data is not encrypted differently (i.e. with the new encryption key) since the detected events still have to be decrypted and viewed, when the fetch may include Privacy concerns can still arise when decrypting video data of intrusive content unrelated to the cause
Furthermore, in the case of stolen encryption keys, this could lead to unauthorized users decrypting large amounts of video data

Embodiment Construction

[0037] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. Book

[0038] It is an object of the present invention to reduce the risk of unauthorized access to video streams. One solution could be to store

[0039] It should be understood that the following examples only discuss encryption of video streams. However, the present disclosure also applies equally to audio streams

[0040] FIG. 1 shows a timeline t in which an encryption key for encrypting a video stream is changed according to the first embodiment.

[0041] At the second point in time 102b, the second encryption key is activated and the first encryption key is deactivated. encrypted scheduling

[0043] The encryption key used may be a symmetric key for reducing the complexity of the decryption process. Symmetric keys can be

[0044] The predetermined interval 104 may be any suitable interval, such as 30 seco...

Abstract

The present invention relates to content security for video streams. A video capture device configured to capture video data is provided, the image capture device comprising: an image processing pipeline configured to generate a video stream from the captured video data; an encryption key activation module configured to Activates encryption keys on request and deactivates any previously activated encryption keys used to encrypt the video stream, such that only one encryption key is activated for encryption of the video stream at each time instant; Encryption Scheduler a module configured to instruct the encryption key activation module to activate the encryption key at predetermined time intervals; an event handling module configured to instruct the encryption key activation module to activate the encryption key in response to receiving an indication of a detected event; key; an encryption module configured to encrypt the video stream using the activated one encryption key.

Description

Video capture device that secures the content of video streams technical field [0001] The present invention relates to the field of encryption of video streams, and more particularly, to an encryption method for encrypting video streams. Activation and deactivation of cryptographic keys are handled by the device. Background technique [0002] As devices for capturing video data in public spaces are used more frequently, the content of the captured video data Safety is becoming more and more important. The privacy and integrity of those photographed in public locations is an everyday concern that applies to the installation of security cameras One of the reasons why law enforcement or law enforcement officers use body warn cameras (BWCs). for privacy and For security reasons, it is important to use encryption of video data to limit access to video data, both to limit which users are Allows access to decrypted video data, but also restricts which parts of captured vi...
