Abstract

A cellular phone 100 is provided with a data transmitter 102, a detection result receiver 103, and a virus management information storage 104. The data transmitter 102 transmits data to a virus detecting apparatus 20. The detection result receiver 103 receives as virus management information a result of detection on whether the data transmitted by the data transmitter 102 includes a computer virus. The virus management information storage 104 stores the data and the virus management information about the data in association with each other.

Claims

1. A mobile communication terminal comprising:

storage means for storing data, and virus management information indicating whether the data includes a computer virus, in association with each other; and

control means for controlling access to the data stored in said storage means, based on the virus management information stored in the storage means.

2. The mobile communication terminal according to claim 1, further comprising:

transmitting means for transmitting data to an information processing apparatus; and

receiving means for receiving a result of detection on whether the data transmitted by said transmitting means includes a computer virus, as virus management information from said information processing apparatus,

wherein said storage means stores the data transmitted by the transmitting means, and the virus management information about the data, received by the receiving means, in association with each other.

3. The mobile communication terminal according to claim 1, further comprising:

transmitting means for transmitting a data transmission request to a server apparatus; and

receiving means for receiving a result of detection on whether data requested by the transmission request from said transmitting means includes a computer virus, as virus management information along with said data from a relay server apparatus,

wherein said storage means stores the data received by said receiving means, and the virus management information about the data in association with each other.

4. The mobile communication terminal according to claim 1, wherein said virus management information includes information indicating that a process of detecting whether the data includes a computer virus is outstanding.

7. An information processing system comprising the mobile communication terminal as set forth in claim 2, and the information processing apparatus, wherein communication is performed between the mobile communication terminal and the information processing apparatus.

8. An information processing system comprising the mobile communication terminal as set forth in claim 3, and the relay server apparatus, wherein communication is performed between the mobile communication terminal and the relay server apparatus.

5. An information processing apparatus comprising:

receiving means for receiving data transmitted from a mobile communication terminal;

detecting means for detecting whether the data received by said receiving means includes a computer virus; and

transmitting means for transmitting a result of detection by said detecting means to said mobile communication terminal.

6. A relay server apparatus comprising:

receiving means for receiving data transmitted from a server apparatus;

detecting means for detecting whether the data received by said receiving means includes a computer virus; and

transmitting means for transmitting a result of detection by said detecting means to a mobile communication terminal.

9. An information processing method of processing data, the information processing method comprising:

a storage step wherein a mobile communication terminal stores data, and virus management information indicating whether the data includes a computer virus, in association with each other in storage means; and

a control step wherein the mobile communication terminal controls access to the data stored in the storage means, based on the virus management information stored in the storage means.

10. The information processing method according to claim 9, further comprising:

a data transmitting step wherein the mobile communication terminal transmits data to an information processing apparatus;

a data receiving step wherein the information processing apparatus receives the data transmitted in said data transmitting step;

a detecting step wherein the information processing apparatus detects whether the data received in said data receiving step includes a computer virus;

a detection result transmitting step wherein the information processing apparatus transmits a result of detection in said detecting step to the mobile communication terminal; and

a virus management information receiving step wherein the mobile communication terminal receives the result of detection transmitted in said detection result transmitting step, as virus management information from the information processing apparatus,

wherein in said storage step, the mobile communication terminal stores the data transmitted in said data transmitting step, and the virus management information about the data, received in said virus management information receiving step, in association with each other in the storage means.

11. The information processing method according to claim 9, further comprising:

a data transmission request transmitting step wherein the mobile communication terminal transmits a data transmission request to a server apparatus;

a data transmitting step wherein the server apparatus transmits data to a relay server apparatus in response to said data transmission request;

a data receiving step wherein said relay server apparatus receives the data transmitted in said data transmitting step;

a detecting step wherein said relay server apparatus detects whether the data received in said data receiving step includes a computer virus;

a detection result transmitting step wherein the relay server apparatus transmits a result of detection in said detecting step along with the data received in the data receiving step, to the mobile communication terminal; and

a virus management information receiving step wherein the mobile communication terminal receives the result of detection transmitted in said detection result transmitting step, as virus management information along with the data from the relay server apparatus,

wherein in said storage step, the mobile communication terminal stores the data received in said virus management information receiving step, and the virus management information about the data in association with each other in the storage means.

12. The information processing method according to claim 9, wherein said virus management information includes information indicating that a process of detecting whether the data includes a computer virus is outstanding.
