Authentication timestamp determination method and apparatus, and electronic device

Abstract

The embodiment of the invention provides an authentication timestamp determination method and device and electronic equipment. The method is applied to the access equipment and comprises the followingsteps: when a triggering condition for determining an authentication timestamp is met, determining a coordinated world time UTC second number corresponding to the current moment of the access equipment; determining a target time difference corresponding to the to-be-accessed open type network video interface forum ONVIF equipment from a preset corresponding relation about the ONVIF equipment andthe time difference; determining UTC seconds corresponding to the ONVIF equipment to be accessed based on the UTC seconds corresponding to the current moment of the access equipment and the target time difference; and converting UTC seconds corresponding to the ONVIF equipment to be accessed into a timestamp character string as an authentication timestamp. Compared with the prior art, the scheme provided by the embodiment of the invention can realize synchronization of the authentication timestamp sent by the access equipment and the UTC time corresponding to the local time of the ONVIF equipment.

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.
