File encryption method, electronic equipment and external equipment

Abstract

The invention relates to the field of information security, in particular to a file encryption method, electronic equipment and external equipment, and the file encryption method comprises the following steps: obtaining access information of the external equipment accessing the electronic equipment; judging whether the external equipment is authorized equipment or not according to the access information, and if yes, obtaining authorization parameters of the authorized equipment, wherein the authorization parameters comprise at least one of authorization time limit, authorization times and authorization authority; operating the file for the electronic equipment according to the authorization parameter; if not, disconnecting the communication connection with the external equipment, and sending alarm information to a specified terminal. According to the electronic device file encryption method and device, the electronic device file encryption safety can be improved, and the privacy leakage problem of the electronic device can be effectively avoided.

Description

technical field [0001] The invention relates to the field of information security, in particular to a file encryption method, electronic equipment and external equipment. Background technique [0002] With the development of society, electronic devices such as mobile phones and computers have become necessities. Human beings store private information such as their daily life and work documents in electronic devices. Once lost, it is easy to be stolen by criminals, resulting in privacy leakage. Although existing electronic devices have protection measures such as password protection and fingerprint recognition to protect files, the traditional encryption method has a low security level. After multiple attacks by cracking software, the password can still be successfully cracked, resulting in privacy leakage. Contents of the invention [0003] The object of the present invention is to provide a file encryption method, an electronic device and an external device, so as to solv...
