S201, receiving a page access request sent by a target terminal.
The page access request comprises information of a page to be accessed by the target terminal and information of a server corresponding to the page.
In this embodiment, the protection terminal communicates with the target terminal through wireless communication, so that the protection terminal may receive the page access request sent by the target terminal. By way of example, the manner in which wireless communication may include wireless network communication technology (Wi-Fi), general packet radio service (general packet radio service, GPRS), bluetooth, etc.
S202, determining whether a page requested by a page access request is a malicious page, and if so, feeding back information of access failure to a target terminal; if not, processing the page access request to obtain a processing result, and returning the processing result to the target terminal.
Optionally, a feature information base may be stored in the protection terminal in advance, where the feature information base includes malicious feature information of a plurality of malicious pages, after the protection terminal receives a page access request sent by the target terminal, feature extraction may be performed on the page access request to obtain feature information of a page requested by the page access request, where when the feature information of the page includes malicious feature information, it is determined that the page requested by the page access request is a malicious page, and when the feature information of the page does not include malicious feature information, it is determined that the page requested by the page access request is not a malicious page.
In this embodiment, when the page requested by the page access request is a malicious page, the protection terminal sends information of access failure to the target terminal, and the target terminal can display the information to the user through the display interface; when the page requested by the page access request is not a malicious page, the protection terminal processes the page access request to obtain a processing result, and optionally, the protection terminal can acquire a corresponding page according to the page access request and send the page to the target terminal.
In the page access method, a page access request sent by a target terminal is received; determining whether a page requested by the page access request is a malicious page, if so, feeding back information of access failure to a target terminal; if not, processing the page access request to obtain a processing result, and returning the processing result to the target terminal. When the page requested by the page access request is a malicious interface, stopping to continuously access the page, effectively protecting the target terminal, and protecting the malicious page and malicious characters in the page by using a protection component of each application program in the prior art.

S503, determining that the page requested by the page access request is not a malicious page.
The second sample library comprises address information corresponding to a plurality of pages, and the second sample library is obtained from sample library nodes of the block chain.
In this embodiment, the page access request is parsed to obtain address information corresponding to the page requested by the page access request, if the second sample library includes the address information, it is determined that the page requested by the page access request is a malicious page, and if the second sample library does not include the address information, it is determined that the page requested by the page access request is not a malicious page.
Optionally, the blockchain may include a sample library node and a plurality of product provider nodes, where the sample library node is configured to store a second sample library, each product provider node may send an addition request to the other product provider nodes and the sample library node, where the addition request may include address information corresponding to an added page, each product provider node may respond to the addition request, and the response result may be consent or disagreement, and when the response result is that the number of consent is greater than or equal to a preset number, the sample library node updates the second sample library according to the addition request, and when the response result is that the number of consent is less than the preset number, the addition request fails.
In this embodiment, whether the page requested by the page access request is a malicious page is determined according to the second sample library, so that the determination result is more accurate, and the problem that the malicious page is sent to the target terminal and the protection effect on the target terminal is affected due to the fact that the malicious page is acquired is avoided.
