In addition, the pressing parameters including pressing area or pressing force can be obtained in this way.

By adopting this embodiment, K groups of pressing parameters can be matched with K groups of preset pressing parameters. Only when the matching is successful, can the unlocking operation be performed. Therefore, the security of the terminal is enhanced. If the matching of pressing data fails, and P is greater than 1 and less than K, the brightness of at least one of the P patterns can be reduced.

As a possible implementation manner, the pressing parameter is at least one of the position of the pattern, pressing time, pressing force value and pressing area.

As a possible implementation manner, the above-mentioned processor 3000 determines K sets of pressing parameters for the user to press K patterns in the M patterns, specifically:

When the user's pressing operation on the pattern i among the K patterns among the M patterns is detected, a number corresponding to the pressing operation is displayed on the pattern i, wherein the number is used to cover the pattern i, the pattern i is any one of the K patterns;

The pressing parameter represented by the number is used as the pressing parameter of the pattern i.

As a possible implementation manner, the processor 3000 matches the K sets of compression parameters with the K sets of preset compression parameters, specifically:

judging whether the positions of the K patterns included in the K sets of compression parameters are consistent with the positions of the K patterns included in the K sets of preset compression parameters;

If so, calculate the K sets of compression parameters according to preset rules to obtain a set of verification parameters;

It is judged whether the set of verification parameters is within the range corresponding to the set of verification parameters corresponding to the preset pressing parameters.

As a possible implementation, after the processor 3000 matches the K sets of compression parameters with the K sets of preset compression parameters, it is further specifically used to:

In the case of failure to match the positions of the P patterns corresponding to the P groups of pressing parameters in the K groups of pressing parameters, reduce the brightness of the corresponding area of at least one of the P patterns, wherein the P is greater than 1 and an integer less than K.

It can be seen that the terminal described in this embodiment can display M patterns on the touch screen of the terminal when it detects that the terminal is awakened, and the M is an integer greater than 1; it is determined that the user presses the M patterns K sets of pressing parameters of K patterns in the pattern, said K is an integer greater than or equal to 1 and less than or equal to said M; matching said K sets of pressing parameters with K sets of preset pressing parameters; When the K sets of pressing parameters are successfully matched with the K sets of preset pressing parameters, an unlocking operation is performed on the terminal. By adopting this embodiment, K groups of pressing parameters can be matched with K groups of preset pressing parameters, and only when the matching is successful can the unlocking operation be performed, thereby enhancing the security of the terminal.
