Embodiment Construction
[0031] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.
[0032] This embodiment provides an anti-crawler system, which includes a server and a client.
[0033] Among them, such as figure 1 As shown, the server includes a memory 1, a generation module 2, an extraction module 3, an encryption module 4 and a verification module 5, the memory 1 can be added or changed, and multiple functions, and each function includes an encryption function and a corresponding decryption function.
[0034] The functions of each functional module are introduced as follows:
[0035] The generation module 2 is used to randomly generate a random password after receiving the request information for obtaining data sent by a client;
[0036] The extraction module 3 is used to randomly extract at least one function from these functions;
[0037] The encryption module 4 is used to sequentially encrypt the r...

The invention provides a server, an anti-crawler system and an anti-crawler verification method. The server comprises a memory, a generating module, an extracting module, an encrypting module and a verifying module. A plurality of functions are stored in the memory, and each function comprises an encryption function and a decryption function. The generating module randomly generates a random password after obtaining data request information sent from a client; the extracting module randomly extracts at least one function from the functions; the encrypting module utilizes the extracted functions to carry out encryption on the random password and sends the encrypted password after the encryption to the client; and the verifying module carries out verification on a decryption result when receiving the decryption result for the encrypted password from the client, if the decryption result is identical with the random password, the data required by the request information is sent to the client; and if not, the data required by the request information is not sent to the client. According to the invention, the number of the encrypted password and the encryption sequence are random, and difficulty of clawer cracking is increased.
Description
technical field [0001] The invention relates to an anti-crawler technology, in particular to a server for dynamically selecting encryption and decryption functions, an anti-crawler system including the server, and an anti-crawler verification method realized by the anti-crawler system. Background technique [0002] With the development of the Internet, the number of crawlers on the Internet is increasing day by day. The crawlers will forge user behavior and continuously access the server to obtain information. This will greatly slow down the server speed and cause the risk of private information resources being obtained in batches. How to protect the company's private information resources by adopting advanced anti-reptile means has become an urgent problem to be solved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a server, an anti-crawler system and an anti-crawler verification system in order to overcome th...
