<p>Provided is a method for detecting, in real time, loss of data transfer between information devices connected to each other via an external network. In a first information device: an application is used to divide, for a temporal transfer direction, transfer data stored for writing; a hash value is generated for the divided data; and the hash value is stored, as write hash value, into a dedicated buffer of the first information device. The divided data and write hash value are then sent from the first information device to a second information device with the write hash value being associated with the divided data in the first information device. In the second information device, the divided data and write hash value are received and then stored into a dedicated buffer of the second information device with the write hash value being associated with the divided data. In the second information device, a hash value is generated for the received divided data and then stored, as read hash value, into the dedicated buffer of the second information device. The write hash value and the read hash value are compared with each other, and if these values do not match each other, it is then determined that a transfer data loss occurred during the transfer of the divided data.</p> |
