VIDEO-PHONE DEVICE
A video-phone device which transmits and receives sharable data to and from video-phones belonging to other parties is provided with a communication control means which, upon receiving a reception request or a transmission request for shareable data, assesses whether or not the reception request or the transmission request satisfies predetermined conditions, specifically, whether or not the other party has been stored in a recoding unit as a party to which transmission/reception of sharable data is permitted, and receives sharable data from the other party or transmits sharable data to the other party only when the conditions are satisfied. Thus the video-phone can automatically permit only reception of sharable data from trusted parties on the other end of a communication line, or transmission of sharable data to trusted parties on the other end of a communication line.
1 . A video-phone device for exchanging shared data with a call counterpart, the video-phone device comprising communication control means for determining, once a reception request or a transmission request regarding said shared data has been received, whether or not said reception request or transmission request satisfies a predetermined condition, and receiving said shared data from said call counterpart or transmitting said shared data to said call counterpart only when said predetermined condition is satisfied.
2 . The video-phone device according to claim 1 , wherein the video-phone device is further provided with a recording unit for recording call counterparts with which the exchange of said shared data is allowed by said video-phone device, said communication control means receives said shared data from said call counterpart or transmits said shared data to said call counterpart only when, as said predetermined condition, the call counterpart which has transmitted said reception request or transmission request is a call counterpart with which the exchanging of said shared data is allowed.
3 . The video-phone device according to claim 2 , wherein the video-phone device is further provided with registering means for registering the call counterparts in said recording unit, said registering means registers, as a call counterpart with which the exchanging of said shared data is allowed, a call counterpart with which said communication control means has exchanged said shared data.
4 . The video-phone device according to claim 1 , wherein said communication control means receives said shared data from said call counterpart or transmits said shared data to said call counterpart only when, as said predetermined condition, the call counterpart which has transmitted the reception request or the transmission request regarding said shared data is a billing party.
5 . The video-phone device according to claim 1 , wherein said communication control means checks with the user whether or not to allow transmission or reception of said shared data in a case where the reception request or the transmission request regarding said shared data does not satisfy said predetermined condition.
6 . The video-phone device according to claim 1 , wherein the communication control means allows reception of said shared data from said call counterpart or transmission of said shared data to said call counterpart in a case where, once the exchanging of shared data has been allowed during the same call, a transmission request or a reception request regarding said shared data is again received.
