Receiving means for receiving content from an external device;
Generating means for generating identification information for uniquely identifying the content based on the partial data of the content;
Recording control means for associating and recording the received identification information of the content and the content on a recording medium;
When the content is received from the external device by the receiving means, only the partial data of the content is received before the entire content data is received, and the generation is performed based on the received partial data of the content Control means for generating the identification information by means and controlling to compare with the identification information of the content already recorded on the recording medium,
Based on the result of the comparison, the control means switches between controlling to receive the entire content data or not to receive the entire content data using the receiving means. Information processing device.   If the identification information does not match as a result of the comparison, the control means controls to receive the entire data of the content using the receiving means, and as a result of the comparison by the control means, the identification information is 2. The information processing apparatus according to claim 1, wherein if the two pieces of data match, the information processing apparatus controls not to receive the entire content data. The information processing apparatus according to claim 1, wherein the content is image data, and the partial data includes at least a part of a thumbnail of the image data. 4. The partial data is obtained by cutting out a part of data from a data position obtained by removing a predetermined size from the top of the content data. Information processing device. The information processing apparatus according to claim 1, wherein the identification information is a hash value of the partial data. When establishing a connection with the external device, the receiving means receives device information from the external device,
The said control means determines the acquisition position and size of the said partial data based on the model name and digital camera information which are contained in this received device information, The any one of Claim 1 thru | or 5 characterized by the above-mentioned. Information processing device. The control means further determines whether or not the external device has a function of generating the identification information before receiving only the partial data of the content,
When it is determined that the external device has a function of generating the identification information,
Control to receive the identification information without receiving the partial data of the content,
When it is determined that the external device does not have a function of generating the identification information,
From said external device, the information processing apparatus according to any one of claims 1 to 6, wherein the controller controls so as to receive only partial data of the content. A receiving process for receiving content from an external device;
A generating step for generating identification information for uniquely identifying the content based on the partial data of the content;
A recording control step of associating the received content identification information with the content and recording it on a recording medium;
Before receiving the entire content data in the receiving step, only the partial data of the content is received, the identification information is generated based on the received partial data of the content, and is already recorded on the recording medium A control step for controlling to compare with the identification information of the content;
And a control method for switching between controlling to receive the entire content data or not to receive the entire content data based on the comparison result. A computer-readable program for causing a computer to function as each unit of the information processing apparatus according to any one of claims 1 to 7 .
