Method, device and electronic equipment for determining authentication time stamp

Abstract

Embodiments of the present invention provide a method, device and electronic equipment for determining an authentication time stamp. The method is applied to the access device, including: when the trigger condition for determining the authentication time stamp is met, determine the UTC seconds corresponding to the current moment of the access device; from the preset correspondence between the ONVIF device and the time difference, Determine the target time difference corresponding to the ONVIF device to be connected to the Open Network Video Interface Forum; based on the UTC seconds corresponding to the current moment of the access device and the target time difference, determine the UTC seconds corresponding to the ONVIF device to be connected; the ONVIF device to be connected The corresponding UTC seconds are converted to a timestamp string, which is used as the authentication timestamp. Compared with the prior art, when applied to the solution provided by the embodiment of the present invention, the authentication timestamp sent by the access device can be synchronized with the UTC time corresponding to the local time of the ONVIF device.

Description

technical field [0001] The invention relates to the technical field of video surveillance systems, in particular to a method, device and electronic equipment for determining an authentication time stamp. Background technique [0002] ONVIF (Open Network Video Interface Forum, Open Network Video Interface Forum) is an open industry standard based on open and open principles. It mainly defines a common protocol for information exchange between network video devices, including device search , real-time video, audio, metadata and control information, etc. [0003] As a standard specification for device access, the ONVIF protocol is playing an increasingly important role in the security industry. A large number of manufacturers use the ONVIF protocol to regulate their own cameras, video recorders and other monitoring equipment products, and these equipment can be called ONVIF equipment. [0004] When the ONVIF device is connected to the access device such as the video surveilla...

Problems solved by technology

Specifically, when the authentication timestamp sent by the access device as the initiator of the access request is too different from the local time of the ONVIF device, the authentication will fail, resulting in an access exception

[0006] However, since the authentication timestamp sent by the access device may be affected by cross-time zones, daylight saving time, etc., the difference between the authentication timestamp sent by the access device and the local time of the ONVIF device is too large, and, due to different ONVIF devices and The factory default time of the access device may be different, which will also cause a large difference between the authentication timestamp sent by the access device and the local time of the ONVIF device. Therefore, based on the above reasons, the access between the ONVIF device and the access device may be abnormal.
