Network camera recognition method, device and system based on ONVIF protocol standard

Abstract

The invention relates to the technical field of network camera recognition, and discloses a network camera recognition method, device and system based on an ONVIF protocol standard. The method comprises the following steps: sending a discovery data packet to a camera server; collecting a camera ONVIF address meeting the condition of discovering the sent data packet; sending a request to the ONVIF address, obtaining a response data packet fed back by the camera, and analyzing the response data packet to obtain feature information; and associating the feature information with registration information stored in an information base, generating a feature fingerprint, and displaying the registration information of the recognized camera. The discovery data packet is sent through the server, the camera feeds back the response data packet, the server receives the response data packet, analyzes the response data packet and then associates the response data packet with the target information base to form the feature fingerprint, the feature fingerprint is used for calling camera information in the target information base according to the feature extraction rule, additional authentication is not needed. The further interaction between the server and the camera server is facilitated.

Description

technical field [0001] The present application relates to the technical field of network camera identification, in particular to a method, device and system for network camera identification based on the ONVIF protocol standard. Background technique [0002] ONVIF (Open Network Video Interface Forum, Open Network Video Interface Forum) is an international open network video product standard network interface development forum, whose goal is to promote the development and use of global open standards for physical IP-based security product interfaces. The ONVIF standard will define a common protocol for information exchange between network video devices, including device discovery, real-time video, audio, metadata and control information. The interfaces defined in the device management and control part of the ONVIF specification are provided in the form of Web Services, and the device serves as the service provider as the server. The ONVIF specification covers complete XML an...

Problems solved by technology

[0003] Many network camera identification technologies only achieve the level of identifying the product, and do not dig out more information about the identified product. If you want to obtain the specific device information of a product (such as: the main control version of the device ID, code version number, operating system, etc.), almost all are identified by the private protocols of major manufacturers, but there are some huge difficulties in identifying according to the private protocols: not open source, protocol data is extremely difficult to find, and some underlying SDKs The development is confusing, and major manufacturers will consider privacy and security issues when designing, and will add an authentication mechanism to the protocol. Only after the authentication is successful can further interaction with the camera server be allowed. Currently, cracking the authentication mechanism is also a major technical problem.
