In order to solve the problems of high labor cost, low efficiency of monitoring advertisement playing and low accuracy of the conventional method for monitoring the electronic advertisement putting condition under the line, the embodiment of the specification provides an advertisement monitoring and playing method based on a block chain. The execution subject of the method provided by the embodiment of the present specification may be, but is not limited to, an advertisement monitoring and broadcasting device and the like, which can be configured to execute at least one of the method devices provided by the embodiment of the present invention.

For convenience of description, the following description will be made of an embodiment of the method, taking an execution subject of the method as an example of an advertisement monitoring device capable of executing the method. It is understood that the method is performed by the advertisement monitoring device as an exemplary illustration, and should not be construed as a limitation on the method.

Specifically, an implementation flow diagram of an advertisement monitoring and broadcasting method based on a blockchain provided by one or more embodiments of the present specification is shown in fig. 1, and includes:

step 110, acquiring a screen capture image of the target advertisement playing device and identification information of the target advertisement playing device.

It should be understood that, in order to obtain a screen capture image of a target advertisement played by a playing device of the target advertisement in real time, an embodiment of the present specification may embed a monitoring program in the playing device of the target advertisement, where the monitoring program may set a timing screen capture function, that is, a screen capture operation may be performed on a playing screen of the playing device of the target advertisement every preset time period.

And 120, generating block chain check information based on the screen capture image and the identification information, wherein the block chain check information is used for verifying the contents of the screen capture image and the identification information.

Optionally, as an embodiment, since each block in the block chain has a limited storage space, it is generally not suitable to store too large data, at this time, information such as an original screen capture image may be encrypted by using a digest algorithm to obtain a digest of the original information, and then the digest of the original information is uploaded to the block chain. Then, generating block chain check information based on the screenshot image and the identification information, the block chain check information being used as the content for verifying the screenshot image and the identification information, including:

acquiring an abstract of a screen shot image;

acquiring a first signature of a playing device of the target advertisement on an abstract of a screen capture image and a second signature of the playing device of the target advertisement on identification information of the playing device of the target advertisement;

and generating block chain checking information based on the first signature, the second signature and the identification information of the playing device of the target advertisement.

The obtaining mode of the summary of the screen capture image can be obtained through a picture hash algorithm, such as a picture hash algorithm of hash, dhash, and the like.
