Safety camera system based on digital watermarking technology and application method thereof

Abstract

The invention discloses a security camera system based on a digital watermarking technology and an application method thereof. The security camera system comprises terminal equipment, an application server and a cloud server, wherein the terminal equipment is used for collecting media data and loading a digital watermark generated by digital watermark cryptography operation into the media data by adopting a digital watermark algorithm; the application server is used for extracting the digital watermark loaded in the media data added with the digital watermark from the media data added with the digital watermark, and sending the extracted digital watermark to the cloud server for verification; and the cloud server is used for verifying the digital watermark sent by the application server. According to the embodiment of the invention, through the security camera system based on the digital watermarking technology, a service manufacturer can confirm the source of the media data, various attack behaviors on remote user identity verification are effectively prevented, attack behaviors of a virtual camera and the like are effectively prevented, and the security level of remote services developed based on the Internet is improved.

Description

technical field [0001] The invention relates to the Internet field, in particular to a security camera system based on digital watermark technology and an application method thereof. Background technique [0002] With the vigorous development of the Internet, service providers can reach users remotely, and users can carry out businesses such as banking and insurance without meeting offline. Due to the non-contact mode of remote business, service providers cannot identify customers face-to-face, and there are security risks. The regulatory authorities have very strict requirements for user identity verification. [0003] In order to meet regulatory requirements, service providers usually collect pictures or videos of the user's face or other parts through the camera module of the user terminal device, and then perform background analysis to achieve the purpose of identity verification. However, this also facilitates cybercrime, so various identity fraud technologies have eme...

Problems solved by technology

[0004] However, there is a kind of fraudulent technology that is difficult to prevent by relying on the existing fraud identification technology. This fraudulent technology is virtual camera and related injection attack technology. Inject stolen, pre-shot, or other technically synthesized pictures and videos during video collection to deceive liveness detection and risk control technologies. Because virtual cameras and other injection attack operating modes are indistinguishable from hardware camera devices, this kind of attack is extremely difficult to prevent , but also caused huge economic and reputation losses to related service providers
