Description
Technical field
The invention belongs to field of encryption more particularly to the methods and electronic equipment of a kind of file encryption.
Background technology
Encryption is as a kind of mode for ensureing data safety, it is not now just to have, and the history of its generation is quite remote,
It is initiated by being traced in B.C. 2000（Several centuries）Although its not now encryption technology that we are said
（Encryption is not cried even）, but a kind of encrypted concept is used as, just it is born really before several centuries.Egyptian was most at that time
Special pictograph is first used as information coding, as time goes by, Babylon, Mesopotamia and Greece's civilization
All begin to use certain methods to protect their written information.
Generally all there are privacy photo or video on electronic equipment at present, be easy to cause when electronic equipment is used by others
Privacy leakage brings great body and mind to perplex to user.
Invention content
The embodiment of the present invention is designed to provide a kind of method of the file encryption applied to electronic equipment, it is intended to solve
The problem of easy privacy of purpose electronic equipment leaks.
To solve the above-mentioned problems, the invention is realized in this way：A kind of method of file encryption, sets applied to electronics
It is standby, it the described method comprises the following steps：
Whether detection pre-set user sends out file encryption instruction；
Obtain the facial characteristics of active user；
According to the facial characteristics of pre-set user and the facial characteristics of the acquisition and file encryption instruction control pair
Predetermined encryption file in electronic equipment is encrypted.
Further, the step of whether the detection pre-set user sends out file encryption instruction, including：
When active user carries out picture/video tour, the sound of ambient enviroment is monitored；
The voiceprint of the sound listened to is matched with default voiceprint, and to the sound listened into
Row language identification；
Reach preset matching degree threshold value in the voiceprint of the sound listened to and the matching degree of default voiceprint,
And the sound that listens to carry out the content after language identification it is identical with preset language information when, then be judged as pre-set user hair
File encryption instruction is gone out.
Further, the acquisition modes of the facial characteristics of the active user are the camera by electronic equipment to current
User is shot, and the facial characteristics of active user is obtained according to default face recognition algorithm.
Further, it is described to be added according to the facial characteristics of pre-set user and the facial characteristics of the acquisition and the file
The step of predetermined encryption file in electronic equipment is encrypted in close instruction control, including：
The facial characteristics of the facial characteristics of the acquisition and pre-set user is compared；
File encryption instruction, and the facial characteristics of the facial characteristics of the acquisition and pre-set user are had issued in pre-set user
Similarity when being less than default similarity threshold, the predetermined encryption file in electronic equipment is encrypted.
Further, in the facial characteristics and the file of the facial characteristics according to pre-set user and the acquisition
It is further comprising the steps of after the step of predetermined encryption file in electronic equipment is encrypted in encrypted instruction control：
Whether detection pre-set user sends out file decryption instruction, and reacquires the facial characteristics of active user；
File decryption instruction, and the facial characteristics of the reacquisition and default facial characteristics are had issued in pre-set user
When similarity is more than default similarity threshold, the predetermined encryption file in electronic equipment is decrypted.
