Identity identification method and system for image and video data

Abstract

The invention discloses an identity identification method and an identity identification system for image and video data. The identity identification method comprises the steps of: during acquisitionof each image, forming identity identification information of the image by reading local information, wherein the identity identification information at least comprises an image generation time, an image generation location, image generation equipment and a digital signature of the image; performing image coding on the identity identification information to enable coded image data to comprise theidentity identification information of the image, so as to obtain the unique identity identification of the image, i.e., an image ID. For video data, a video ID describing video sequence information is formed by image identity identification information of key frames. Through adoption of the identity identification method of the invention, the unique ID is designed for the image and video data, thereby providing meta-information with uniqueness, authority, safety, universality and privacy for processing such as coding, channel transmission and decoding reestablishment, space-time synchronization fused analysis, tracing and tamper resistant of the image.

Description

technical field [0001] The present invention relates to a method and system for identification of image and video data, specifically, a method and system for identification of image and video data itself. Background technique [0002] According to the definition of the "Electronic Signature Law of the People's Republic of China", "an electronic signature refers to the data contained in electronic form in a data message and attached to identify the identity of the signatory and to indicate that the signatory approves the content." A means of authentication. [0003] After searching the existing technologies, it is found that although there are already a large number of technologies related to data signatures, they all focus on verifying electronic signatures. There are few systems for identifying and authenticating image and video data itself. Although a small number of patent applications for generating data signatures for image data have been retrieved at present, their f...

Problems solved by technology

Both of the technologies disclosed in these two patents generate digital signatures through image feature extraction. In terms of purpose, the purpose of the two patent applications is to make similar judgments on multiple images, lacking time and location information for image acquisition, and unable to meet the requirements of video images. Application of data in the fields of associative storage, fusion analysis, traceability and anti-tampering
