Terminal Authentication Method and Device
First Claim
Patent Images
1. A terminal authentication method, comprising:
- sensing pressure information through a touch screen of a terminal, wherein the pressure information comprises a pressing strength value of a pressed contact when a user presses the touch screen;
comparing the sensed pressure information with an authentication password stored in the terminal by using the sensed pressure information as an authentication password;
when the sensed pressure information matches the stored authentication password, determining, that password authentication succeeds; and
when the sensed pressure information does not match the determining, that password authentication fails.

Abstract
An authentication method includes sensing, pressure information through a touch screen. The pressure information includes a pressing strength value of a pressed contact when a user presses the touch screen. The sensed pressure information is compared with an authentication password by using the sensed pressure information as an authentication password. If the sensed pressure information matches the stored authentication password, it is determined that password authentication succeeds; otherwise, the password authentication fails.

6. A terminal authentication device, comprising:
-
a sensing unit; an authentication unit; and a storage unit; wherein the sensing unit is configured to sense pressure information through a touch screen and to send the pressure information to the authentication unit, wherein the pressure information comprises a pressing strength value of a pressed contact when a user presses the touch screen; wherein the storage unit is configured to store an authentication password; and wherein the authentication unit is configured to receive the pressure information from the sensing unit and to compare the pressure information with the authentication password obtained from the storage unit by using the pressure information as an authentication password, wherein if the sensed pressure information matches the stored authentication password, the terminal determines that password authentication succeeds, and if the sensed pressure information does not match the stored authentication password, the terminal determines that password authentication fails. - View Dependent Claims (7, 8, 9, 10)
