technical field

The present application relates to big data processing, and in particular, to a data encryption method, device, electronic device and computer-readable storage medium based on matrix operation.

Background technique

At present, many companies or groups will crawl network data through crawler programs to obtain the required information. Therefore, while we exchange network information, we must avoid important data being crawled by third parties, resulting in economic losses or unknown risks. That is to say, in the face of numerous crawling tools and data protection cracking measures, how to protect valuable information and data from being stolen by crawlers has become more important. The most commonly used anti-crawling tools and methods are:

1. The monitoring program is implemented in the background of the server. By counting the statistical indicators within a unit time (such as accessing ip, accessing session, accessing User_Agent), a risk alarm is realized when the preset threshold is exceeded, thereby blocking the follow-up of the access terminal corresponding to the statistical indicator. ask.

2. The important data on the server side can only be obtained after the account registration and login of the access side. At the same time, the dynamic effects of js and AJAX are used to allow only normal login users to access, so that the crawler cannot read the important data normally.

technical problem

The inventor realizes that the above method mainly has the following drawbacks: it is easier for crawler users to bypass the anti-crawling rules by forging traces, and some monitoring methods (such as statistical access to User_Agent) cause serious accidental damage, which is easy to cause errors to ordinary users. Interception, resulting in poor normal user experience. When the crawler user bypasses the anti-crawler rules, the original real data on the server side will be completely exposed to the crawler user, and the data security is not high enough. In addition, the existing data encryption methods based on matrix operations are mainly implemented by symmetric encryption AES and asymmetric encryption RSA algorithms. The general usage scenario is simple information such as login password encryption. For larger data, such as tens of KB or even hundreds of KB Encrypting the data is quite performance-intensive and not practical. Moreover, AES can be deciphered in essence. Even if salt is added, additional transmission and storage are required for salt. Direct original transmission will also face the risk of being crawled. Although RSA is safe, it also requires two transmissions to obtain, encryption efficiency Lower, how to securely store the private key generated by the front-end is also a problem.
