Information processing device, information processing method, and program

Abstract

There is provided an information processing device including a storage unit configured to store applications, application information corresponding to each of the applications, and state management information in which the application information is stored in association with a priority level, and a control unit configured to control a valid state and an invalid state of the application by managing the application information stored in the state management information based on a process command.

1 . An information processing device comprising:
 a storage unit configured to store applications, application information corresponding to each of the applications, and state management information in which the application information is stored in association with a priority level; and   a control unit configured to control a valid state and an invalid state of the application by managing the application information stored in the state management information based on a process command,   wherein the control unit
 causes one application to enter a valid state by adding the application information corresponding to the one application to the state management information, and 
 causes one application stored in the state management information to enter an invalid state by deleting the application information corresponding to the one application from the state management information. 
   
     
     
         2 . The information processing device according to  claim 1 ,
 wherein the application information includes system information used to identify a system in which the application is used, and   wherein, when the system information included in the application information and corresponding to an application newly set in the valid state is included in the application information already stored in the state management information, the control unit does not add the application information corresponding to the application newly set in the valid state to the state management information.   
     
     
         3 . The information processing device according to  claim 1 , wherein the control unit controls a priority level associated with the application information stored in the state management information through deletion of the application information from the state management information and addition of the application information to the state management information. 
     
     
         4 . The information processing device according to  claim 1 , wherein the control unit
 manages the applications in a first layer, and   manages the application information corresponding to each of the applications and the state management information in a second layer which is lower than the first layer.   
     
     
         5 . The information processing device according to  claim 4 , wherein the control unit further provides a third layer which is lower than the second layer, and
 manages, in the third layer, the state management information copied from the state management information managed in the second layer.   
     
     
         6 . The information processing device according to  claim 5 ,
 wherein the application information includes mode information regulating whether a response to a polling signal is given, and   wherein, when the control unit updates the mode information included in the state management information, the control unit updates the mode information included in the state management information managed in the third layer but does not update the mode information included in the state management information managed in the second layer.   
     
     
         7 . The information processing device according to  claim 6 ,
 wherein the storage unit includes a volatile recording medium and a non-volatile recording medium,   wherein the mode information forming the application information included in the state management information is stored in the volatile recording medium, and   wherein, among information forming the application information included in the state management information, information excluding the mode information is stored in the non-volatile recording medium.   
     
     
         8 . An information processing device comprising:
 a storage unit configured to store applications, application information corresponding to each of the applications, and state management information in which the application information is stored in association with a priority level;   a control unit configured to control a valid state and an invalid state of the application by managing the application information stored in the state management information;   a communication unit configured to execute contactless communication with an external device; and   an operation unit configured to be operable by a user,   wherein the control unit
 controls the valid state and the invalid state of the application based on a process command received from the external device by the communication unit or a process command which is based on a user's operation transmitted from the operation unit, 
 causes one application to enter a valid state by adding the application information corresponding to the one application to the state management information, and 
 causes one application stored in the state management information to enter an invalid state by deleting the application information corresponding to the one application from the state management information. 
   
     
     
         9 . An information processing device comprising:
 a storage unit configured to store state management information in which application information is stored in association with a priority level; and   a control unit configured to control a valid state and an invalid state of the application by managing the application information stored in the state management information based on a process command,   wherein the control unit
 causes one application to enter a valid state by adding the application information corresponding to the one application to the state management information, and 
 causes one application stored in the state management information to enter an invalid state by deleting the application information corresponding to the one application from the state management information. 
   
     
     
         10 . An information processing method comprising:
 a step of controlling valid states and invalid states of applications by managing, based on a process command, application information stored in state management information which is stored in a storage unit configured to store the applications, the application information corresponding to each of the applications, and the state management information in which the application information is stored in association with a priority level,   wherein, in the controlling step,
 one application is caused to enter a valid state by adding the application information corresponding to the one application to the state management information, and 
 one application stored in the state management information is caused to enter an invalid state by deleting the application information corresponding to the one application from the state management information. 
   
     
     
         11 . A program for causing a computer to execute:
 a step of controlling valid states and invalid states of applications by managing, based on a process command, application information stored in state management information which is stored in a storage unit configured to store the applications, the application information corresponding to each of the applications, and the state management information in which the application information is stored in association with a priority level,   wherein, in the controlling step,
 one application is caused to enter a valid state by adding the application information corresponding to the one application to the state management information, and 
 one application stored in the state management information is caused to enter an invalid state by deleting the application information corresponding to the one application from the state management information.
