Embodiment Construction

[0051] The video traceability system and traceability method of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0052] The video traceability system of the present invention includes a client, a camera and a cloud platform server, and the three parts are connected through a network.

[0053] A control APP is installed on the client end for information interaction with the camera and the cloud platform server, and the APP has the following functions:

[0054] 1) User login and registration: used to create a user account, collect basic user information, and send it to the cloud platform server. The user basic information includes user name, password, user mobile phone number, email address, bound camera ID, etc.;

[0055] 2) Command sending: used to send commands such as turning on and off the camera, turning on and off video recording, etc. to the camera;

[0056] 3) Video reception: Complete th...

Abstract

The invention discloses a video tracing system and a video tracing method, and the method comprises the steps: user registration: enabling a user to register on a client APP before the user uses a camera, and transmitting a user name, a password, a cellphone number, a mailbox and a camera ID of a user account to a cloud platform server database for storage, wherein the user logs in the APP, the cloud platform server verifies the identity of the user, and after the identity is verified to be correct, safe network connection for controlling the APP and the camera is established; embedding a digital watermark, namely embedding the camera ID into a video frame as a watermark through a robust blind watermark embedding method while a user sends out a shooting instruction; and video tracing: thecloud platform server receives the to-be-traced video, extracts the watermark from the video stream, and queries the user information bound with the camera ID in the database to realize video tracing.According to the method, the camera ID can be embedded into the video to serve as a transparent watermark, and a video source is effectively traced.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to a video traceability system and a video traceability method. Background technique [0002] Digital watermarking technology is currently one of the most important technologies used to protect video image information, and to realize video traceability, digital watermarking needs to have the following two characteristics, concealment and robustness. Concealment, that is, the existence of the watermark will not affect the visual effect of the work, and it is invisible under visual conditions; robustness, that is, the watermark must be able to resist the attacks of general signal processing and various geometric transformations, and it is difficult to be removed. Destruction and forgery. The blind watermarking technology can analyze and extract the watermark content without knowing the original image. [0003] There are two main implementation methods of digital watermarking ...
