The keywords of the privacy type may include characters and numbers associated with a verification code, a password and an account, nouns of private parts in the body, and the like. It can be understood that the security scores corresponding to the tag information and the information content are respectively obtained, the target security scores corresponding to the tag information and the information content are determined, the security level corresponding to the target information is determined according to the target security scores, and the accuracy of determining the security level can be improved.
In steps S11-S13, the attribute information corresponding to the target information is obtained first, then the tag information corresponding to the sender identity information in the attribute information is obtained, and then the security level of the target information is determined according to the tag information and the information content in the attribute information. That is, the security level of the information is determined from the information itself, and the accuracy of determining the security level can be improved.
S703: and determining an acquisition area corresponding to the target information according to the security level.

Wherein d1 is d 2.
It is to be understood that, in the first embodiment, the distance corresponding to the security level is predefined, for example, the larger the security level, the smaller the distance. Thus, after determining the security level, the target distance corresponding to the security level may be determined. After the distances between the receivers and the transmitters are acquired, the area covered by the acquisition position of the receiver corresponding to the target distance can be determined as the acquisition area corresponding to the target information.
If the target distance corresponds to a plurality of receivers, the step of taking an area covered by the acquisition position of the receiver corresponding to the target distance as the acquisition area corresponding to the target information includes: taking a receiver corresponding to the target distance as a target receiver; determining a number of times the target receiver is lit; and taking the area covered by the acquisition position corresponding to the target receiver with the minimum lighting times as the acquisition area corresponding to the target information.
For example, as shown in fig. 3, if the target distance corresponds to the first receiver 1221 and the second receiver 1222, the number of times the first receiver 1221 and the second receiver 1222 are lit up is obtained. If the number of times of lighting the first receiver 1221 is 2031 and the number of times of lighting the second receiver 1222 is 1298, it is determined that the area covered by the acquisition position of the second receiver 1222 is the acquisition area corresponding to the target information, that is, the second acquisition area 1232 is the acquisition area corresponding to the target information.
It can be understood that the area covered by the acquisition position corresponding to the target receiver with the minimum lighting times is selected as the acquisition area corresponding to the target information, so that the damage of the fingerprint acquisition area caused by overhigh use frequency is avoided, and the flexibility of information unlocking is improved.
In a second embodiment, an angle between each of the plurality of receivers and the transmitter is obtained to obtain a plurality of angles; determining a target angle of the plurality of angles corresponding to the security level; and taking the area covered by the acquisition position of the receiver corresponding to the target angle as the acquisition area corresponding to the target information.
The angle uses the transmitter as a coordinate origin to determine the coordinate angle corresponding to each receiver. As shown in fig. 5, the first receiver 1221, the third receiver 1223, the fifth receiver 1225, and the seventh receiver 1227 have an angle of 0 degree, and the second receiver 1222, the fourth receiver 1224, the sixth receiver 1226, and the eighth receiver 1228 have an angle of 45 degrees.
It is to be understood that, in the second embodiment, the angle corresponding to the security level is predefined, for example, the larger the security level, the larger the angle. Thus, after determining the security level, the target angle corresponding to the security level may be determined. After the angles between the receivers and the transmitters are obtained, the area covered by the acquisition position of the receiver corresponding to the target angle can be determined as the acquisition area corresponding to the target information.
The way that the receivers corresponding to the target angle can refer to the receivers corresponding to the target distance is that the receiver corresponding to the target angle is selected as the target receiver, and the area covered by the acquisition position corresponding to the target receiver with the minimum lighting times is used as the acquisition area corresponding to the target information.
