Problems solved by technology

For example: the existing surveillance cameras that are distributed everywhere can usually directly browse the JPEG format images captured by certain trigger conditions without verifying the authenticity of the images, but if the content of the JPEG images is tampered with, it is not easy to be found. The authenticity of the image is difficult to guarantee

Abstract

The invention provides a signature method and device and a signature verification method and device of an image. The image is signed, a signature and / or security information required for signature verification is set at an image data header, thus browsing of image contents is not impacted, whether the image is already tampered with can also be verified, and the tampering problem of the image contents is effectively solved. The signature method of the image includes: using signature information to sign data of the image to obtain signature data; and setting the security information in a mark code area of an image file, and setting the data of the image in a data area of the image file, wherein the security information includes the signature information and the signature data.

Description

technical field [0001] The invention relates to the field of image security protection, in particular to an image signature method and device, and a signature verification method and device. Background technique [0002] With the development of the network, the security requirements for image content are increasing. For example: the existing surveillance cameras that are distributed everywhere can usually directly browse the JPEG format images captured by certain trigger conditions without verifying the authenticity of the images, but if the content of the JPEG images is tampered with, it is not easy to be found. The authenticity of the images cannot be guaranteed. [0003] Therefore, it is urgent to provide a technology to effectively solve the tampering problem of image content. Contents of the invention [0004] In view of this, the present invention provides an image signature method and device, and a signature verification method and device, which can effectively so...
