Method for acquiring electronic data

Abstract

The invention discloses a method for acquiring electronic data. The method comprises the steps that a client enables screen recording; the client clears browsing histories and cache files; the clientparses a DNS and is connected with a server; the client starts a camera to acquire a face image of a current user and verifies the face image; the client stamps a Beidou-timed timestamp on electronicdata; the client generates a snapshot of the electronic data and calculates a Hash value of the electronic data by adopting a Hash algorithm; the client zips the electronic data, the Hash value and the face image to generate a zip packet; the client saves the Hash value and uploads the zip packet to the server; the server unzips the zip packet to generate an unzipped packet; the server verifies the snapshot and the Hash value, saves the electronic data and the Hash value when the snapshot and the Hash value are verified to be qualified and sends feedback to the server; and the client disenables screen recording and saves a recorded video. According to the method, the security of data transmission can be improved.

Description

technical field [0001] The present invention relates to the field of electronic data, and more specifically, to a method for obtaining electronic data. Background technique [0002] With the development of science and technology, electronic devices have become an indispensable part of work and life. When people use electronic devices, a large amount of electronic data will be generated. Documents and photos created at work, in actual work and life, inevitably need to exchange electronic data. Sometimes, in order to prevent data loss caused by local electronic equipment failure, it is also necessary to upload local electronic data to the network server. For cloud storage and backup, data transmission and exchange are required in these processes. [0003] However, electronic data is easy to be tampered with. If the electronic data is maliciously modified during the transmission of electronic data, the electronic data of the transmitting party and the receiving party will be i...

Problems solved by technology

[0003] However, electronic data is easy to be tampered with. If the electronic data is maliciously modified during the transmission of electronic data, the electronic data of the transmitting party and the receiving party will be inconsistent, and the transmission itself will lose its meaning. Therefore, various encryption methods are required. The technology encrypts the transmission process to prevent the electronic data from being maliciously tampered with during the transmission process. However, in addition to being maliciously tampered with during the transmission process, the electronic data may also be transmitted due to code errors rather than malicious tampering. In addition, in the process of transmission, electronic data that has not been transmitted may also be maliciously tampered with, resulting in the receiver being unable to receive correct electronic data
