Abstract
A read document image is stored in a storage apparatus. The destination of data to be transmitted is set, and the data is transmitted to the destination. If transmission fails, the data is discarded on the basis of settings of the data.
Claims11
A data transmission apparatus comprising:
- an input unit adapted to input data;
- an encryption unit adapted to encrypt the data input by said input unit;
- a storage unit adapted to store the data input by said input unit after the data is encrypted by said encryption unit or without encrypting the data;
- a transmission unit adapted to transmit the data stored in said storage unit to a designated destination;
- and
- a control unit adapted to, when said transmission unit fails in transmitting the data stored in said storage unit, control to keep storing the data in said storage unit when the data has been encrypted by said encryption unit, and invalidate the data when the data has not been encrypted by said encryption unit.
3 more elements
A data transmission apparatus comprising:
- an input unit adapted to input data;
- an encryption unit adapted to encrypt the data input by said input unit;
- a storage unit adapted to store the data input by said input unit, together with destination information after the data is encrypted by said encryption unit or without encrypting the data;
- a transmission unit adapted to transmit the data stored in said storage unit, in accordance with the destination information;
- an instruction unit adapted to designate a change of the destination information of the data stored in said storage unit;
- and
- a control unit adapted to control whether to permit the change of the destination information by said instruction unit in accordance with whether the data stored in said storage unit has been encrypted by said encryption unit.
4 more elements
A data transmission apparatus comprising:
- an input unit adapted to input data;
- a storage unit adapted to store the data input by said input unit, together with destination information in correspondence with information for specifying a sender;
- a transmission unit adapted to transmit the data stored in said storage unit, in accordance with the destination information;
- an instruction unit adapted to designate a change of the destination information of the data stored in said storage unit;
- and
- a control unit adapted to control to permit the change of the destination information by said instruction unit when a user who designates the change of the destination information by said instruction unit coincides with the sender who corresponds to the data stored in said storage unit.
3 more elements
A method of controlling a data transmission apparatus which has a storage unit for storing data and transmits data stored in the storage unit, comprising:
- an input step of inputting data;
- an encryption step of encrypting the data input in the input step;
