Abstract

A method protects care information in a care provider terminal. The method includes detecting if there is a network disconnection between the care provider terminal and an authorized access point (AP), operating the care provider terminal in an offline mode until a first predetermined time is over after the network disconnection is detected, activating an alarm operation when the first predetermined time is over, and deleting the care information when a second predetermined time is over after the alarm operation is activated. The method may further include determining whether or not the care provider terminal is connected to an unauthorized AP while counting the first predetermined time or the second predetermined time, and deleting the care information if it is determined that the care provider terminal is connected to the unauthorized AP.

Claims

1. A computer-implemented method of protecting care information in a care provider terminal, the method comprising:

detecting if there is a network disconnection between the care provider terminal and an authorized access point (AP);

operating the care provider terminal in an offline mode until a first predetermined time is over while the network disconnection is maintained after the network disconnection is detected;

activating an alarm operation when the first predetermined time is over while the network disconnection is maintained, the alarm operation being performed to inform a care provider that the first predetermined time is over; and

deleting the care information when a second predetermined time is over while the network disconnection is maintained after the alarm operation is activated,

wherein the care provider terminal has AP information, the AP information including a service set identification (SSID) used to identify the authorized AP.

2. The method of claim 1, wherein the care information includes information on patients and information on care services to be provided to the patients and is downloaded from a server.

3. The method of claim 1, further comprising:

determining whether or not the care provider terminal is connected to an unauthorized AP while counting the first predetermined time or the second predetermined time; and

deleting the care information if it is determined that the care provider terminal is connected to the unauthorized AP.

4. The method of claim 1, further comprising:

receiving initial settings on the care provider terminal before the care provider terminal is registered to the care provider.

5. The method of claim 4, further comprising:

performing installation and activation of a care provider application in the care provider terminal;

receiving a password of an administrator through a log-in interface of the activated care provider application;

determining whether or not the received password matches a pre-set password; and

establishing AP information of the authorized AP in the care provider terminal.

6. The method of claim 1, further comprising:

registering an identification and a password of the care provider and a device ID of the care provider terminal to a server to which the care provider terminal is connected via the authorized AP.

7. The method of claim 1, wherein the first and second predetermined times are determined before the care provider terminal is registered to the care provider.

8. The method of claim 1, further comprising:

deactivating a care provider application installed in the care provider terminal while the alarm operation is activated.

9. The method of claim 1, wherein the care information is downloaded from a server and stored in the care provider terminal, and

wherein the care information is encrypted when it is stored and decrypted when it is read out.

10. The method of claim 9, wherein the encryption and decryption of the care information are performed based on an advanced encryption standard (AES).

11. A care provider terminal of a care provider, comprising:

a memory storing care information downloaded from a server and storing therein instructions;

a processor being controlled by the instructions and performing a method, the method comprising;

detecting if there is a network disconnection between the care provider terminal and an authorized access point (AP);

operating the care provider terminal in an offline mode for a first predetermined time while the network disconnection is maintained;

activating an alarm operation when the first predetermined time is over while the network disconnection is maintained, the alarm operation being performed to inform the care provider that the first predetermined time is over; and

deleting the care information when a second predetermined time is over while the network disconnection is maintained after the alarm operation is activated; and

a timer configured to count the first predetermined time and the second predetermined time sequentially,

wherein the care provider terminal has AP information, the AP information including a service set identification (SSID) used to identify the authorized AP.

12. The care provider terminal of claim 11, wherein the care information includes information on patients and information on care services to be provided to the patients.

13. The care provider terminal of claim 11, wherein the method further comprises:

determining whether or not the care provider terminal is connected to an unauthorized AP while the timer counts the first predetermined time or the second predetermined time; and

deleting the care information if it is determined that the care provider terminal is connected to the unauthorized AP.

14. The care provider terminal of claim 11, wherein the method further comprises, before the care provider terminal is registered to the care provider:

installing and activating a care provider application in the care provider terminal;

receiving a password of an administrator through a log-in interface of the activated care provider application;

determining whether or not the received password matches a pre-set password; and

establishing the AP information of the authorized AP in the care provider terminal.

15. The care provider terminal of claim 11, wherein the method further comprises:

registering an identification and a password of the care provider and a device ID of the care provider terminal to the server to which the care provider terminal is connected via the authorized AP.

16. A non-transitory computer readable medium having stored thereon a program that, when executed, causes a processor to perform a method, the method comprising:

detecting if there is a network disconnection between a care provider terminal and an authorized access point (AP);

operating the care provider terminal in an offline mode until the first predetermined time is over while the network disconnection is maintained after the network disconnection is detected;

activating an alarm operation when the first predetermined time is over while the network disconnection is maintained, the alarm operation being performed to inform a care provider that the first predetermined time is over; and

deleting care information stored in the care provider terminal when a second predetermined time is over while the network disconnection is maintained after the alarm operation is activated,

wherein the care provider terminal has AP information, the AP information including a service set identification (SSID) used to identify the authorized AP.

17. The non-transitory computer readable medium of claim 16, wherein the method further comprises:

determining whether or not the care provider terminal is connected to an unauthorized AP while counting the first predetermined time or the second predetermined time; and

deleting the care information if it is determined that the care provider terminal is connected to the unauthorized AP.

18. The non-transitory computer readable medium of claim 16, wherein the method further comprises:

installing and activating a care provider application in the care provider terminal;

receiving a password of an administrator through a log-in interface of the activated care provider application;

determining whether or not the received password matches a pre-set password; and

establishing the AP information of the authorized AP in the care provider terminal.

19. The non-transitory computer readable medium of claim 16, wherein the method further comprises:

registering an identification and a password of the care provider and a device ID of the care provider terminal to a server to which the care provider terminal is connected via the authorized AP.
