processor controls unlocking based on received acceleration data and data representing a position on a touch panel where proximity or contact of an object is detected when a near field communicator receives acceleration data output from an acceleration sensor of a wearable terminal while locking has been set. ## Claims ### Claim 1 A portable terminal capable of communicating with a wearable terminal, the wearable terminal being capable of transmitting data showing movement of the wearable terminal to the portable terminal, the portable terminal comprising: a communicator configured to communicate with the wearable terminal; at least one processor configured to set and cancel locking; and a touch panel configured to detect proximity or contact of an object, the communicator configured to receive the data showing movement of the wearable terminal from the wearable terminal, and when the communicator receives the data showing movement of the wearable terminal while locking has been set, the at least one processor being configured to unlock the portable terminal when a similarity between a transition of touch positions on the touch panel and a transition of positions stored in a memory is equal to or greater than a first prescribed value, and a similarity between a transition of positions of the wearable terminal and the transition of positions stored in a memory is equal to or greater than a second prescribed value, wherein the transition of touch positions on the touch panel occur simultaneously with the transition of positions of the wearable terminal, and wherein the transition of positions stored in the memory are set in advance by a user of the wearable terminal, wherein the at least one processor is further configured to control unlocking under a first unlocking scheme low in security level based on the received data showing movement of the wearable terminal and the data representing the position on the touch panel where proximity or contact has been detected when the communicator receives the data showing movement of the wearable terminal while locking has been set, and the at least one processor is further configured to control unlocking under a second unlocking scheme high in security level based on the data representing the position on the touch panel where proximity or contact has been detected when the communicator does not receive the data showing movement of the wearable terminal while locking has been set. ### Claim 2 (depends on 1) The portable terminal according to claim 1, wherein the wearable terminal includes an acceleration sensor, the wearable terminal is configured to transmit acceleration data output from the acceleration sensor to the portable terminal as the data showing movement of the wearable terminal, the communicator can receive the acceleration data transmitted from the wearable terminal, and the at least one processor is configured to control unlocking based on the acceleration data and the data representing the position on the touch panel where proximity or contact has been detected when the communicator receives the acceleration data while locking has been set. ### Claim 3 (depends on 1) The portable terminal according to claim 1, wherein the at least one processor is configured to have a screen before locking shown when the communicator receives the data showing movement of the wearable terminal and locking is canceled under the first unlocking scheme. ### Claim 4 (depends on 3) The portable terminal according to claim 3, wherein the at least one processor is configured to have a home screen shown when locking is canceled under the second unlocking scheme without reception of the data showing movement of the wearable terminal by the communicator. ### Claim 5 (depends on 1) The portable terminal according to claim 1, wherein the at least one processor is configured to have a screen high in frequency of use shown when the communicator receives the data showing movement of the wearable terminal and locking is canceled under the first unlocking scheme. ### Claim 6 (depends on 5) The portable terminal according to claim 5, wherein the at least one processor is configured to have a home screen or a screen before locking shown when locking is canceled under the second unlocking scheme without reception of the data showing movement of the wearable terminal by the communicator. ### Claim 7 (depends on 1) The portable terminal according to claim 1, wherein the at least one processor is configured to have a screen associated with an event which occurs while locking has been set shown when the communicator receives the data showing movement of the wearable terminal and locking is canceled under the first unlocking scheme. ### Claim 8 (depends on 7) The portable terminal according to claim 7, wherein the at least one processor is configured to have a screen associated with an event highest in priority among a plurality of events that occur shown when a plurality of events occur while locking has been set. ### Claim 9 (depends on 7) The portable terminal according to claim 7, wherein the at least one processor is configured to have a screen associated with an event which occurs earliest among a plurality of events that occur shown when a plurality of events occur while locking has been set. ### Claim 10 (depends on 7) The portable terminal according to claim 7, wherein the at least one processor is configured to have a screen associated with an event which occurs last among a plurality of events that occur shown when a plurality of events occur while locking has been set. ### Claim 11 (depends on 7) The portable terminal according to claim 7, wherein the at least one processor is configured to have a home screen or a screen before locking shown when locking is canceled under the second unlocking scheme without reception of the data showing movement of the wearable terminal by the communicator. ### Claim 12

the first unlocking scheme includes a slide operation, and the second unlocking scheme includes a pattern input operation. ### Claim 14 A method of controlling locking in a portable terminal capable of communicating with a wearable terminal, the wearable terminal being capable of transmitting data showing movement of the wearable terminal to the portable terminal, the portable terminal including a touch panel configured to detect proximity or contact of an object, the method comprising: the portable terminal setting locking; the portable terminal receiving the data showing movement of the wearable terminal from the wearable terminal; and the portable terminal controlling unlocking when a similarity between a transition of touch positions on the touch panel and a transition of positions stored in a memory is equal to or greater than a first prescribed value, and a similarity between a transition of positions of wearable terminal and the transition of positions stored in a memory is
