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:

a transmitting unit configured to transmit data to an information processing apparatus, the information processing apparatus being configured to detect whether a computer virus is contained in the data;

a receiving unit configured to receive a detection result indicating whether the data transmitted by the transmitting unit includes a computer virus or not according to virus management information from the information processing apparatus;

a storage unit configured to store data transmitted by the transmitting unit, in association with virus control information which indicates when the computer virus is “

Outstanding”

or detection process results received by the receiving unit; and

a control unit configured to permit retrieval of the data when the virus management information is “

OK,”

thereby indicating that the data does not include a virus, and for disallowing retrieval of the data when the virus management information is “

NG,”

thereby indicating that the data is infected with a virus or when the virus management information is “

Outstanding,”

indicating that the computer virus detection process has not been performed for the data,

wherein when a detection result is received by the receiving unit, corresponding virus management information is automatically updated in the storage unit.

2. The mobile communication terminal of claim 1, wherein the mobile communication terminal is a cellular phone.

3. The mobile communication terminal of claim 1, wherein the transmitting unit is configured to perform short-range wireless communications.

4. The mobile communication terminal of claim 3, wherein the transmitting unit performs short-range wireless communications with the information processing apparatus and remote data communications with a relay server.

5. An information processing method of processing data of a mobile communication terminal, the information processing method comprising:

transmitting data from the mobile communication terminal to an information processing apparatus, said information processing apparatus being configured to detect whether a computer virus is contained in the data;

receiving a detection result indicating whether the data transmitted by the mobile communication terminal includes a computer virus or not according to virus management information from the information processing apparatus;

storing data transmitted by the mobile communication terminal, in association with virus control information which indicates when the computer virus is “

Outstanding”

or detection process results received by the mobile communication terminal; and

permitting retrieval of the data when the virus management information is “

OK,”

thereby indicating that the data does not include a virus, and disallowing retrieval of the data when the virus management information is “

NG,”

thereby indicating that the data is infected with a virus or when the virus management information is “

Outstanding,”

indicating that the computer virus detection process has not been performed for the data,

wherein when a detection result is received by the mobile communication terminal, corresponding virus management information is automatically updated.

6. The method of claim 5, wherein the mobile communication terminal is a cellular phone.

7. The method of claim 5, further comprising:

performing short-range wireless communications with external devices.

8. The method of claim 5, further comprising:

performing short-range wireless communications with the information processing apparatus; and

exchanging the data with a relay server over a mobile communication network.
