The client terminal 300 according to an embodiment may include a transceiver 310 and a control unit 320.

The transceiving unit 310 according to an embodiment may receive a binary encrypted file stored in the memory card 142 of the digital photographing apparatus 100 through the network 400.

The controller 320 according to an embodiment may control to transmit the received binary encrypted file to the cloud server 200.

For example, the client terminal 300 may be connected to the digital photographing apparatus 100 through a serial cable to recognize the memory card 142 as a universal serial bus (USB) memory. Accordingly, the control unit 320 may control to read the binary encrypted file stored in the memory card 142 through the transmission/reception unit 310 and transmit it to the cloud server 200 connected to the network.

As another example, a software module capable of accessing the cloud server 100 through the network 400 may be installed in the client terminal 300. Accordingly, the software module may read and store a binary encrypted file whenever the client terminal 300 is connected to the digital photographing device 100, and transmit the encrypted usage data when it is connected to the cloud server 100 later.

8 is a diagram for explaining an example of transmitting usage data to the cloud server 200 via the client terminal 300 according to an embodiment.

Referring to FIG. 8, a method for analyzing usage data of a digital photographing device using a cloud server includes a usage data analysis system 10, a digital photographing device 100, and a cloud shown in FIGS. 1, 2, 5, and 7. It consists of steps processed in a time series by the server 200 or the client terminal 300. Therefore, even if it is omitted below, the usage data analysis system 10, digital photographing device 100, cloud server 200, or client terminal 300 shown in FIGS. 1, 2, 5, and 7 It can be seen that the contents described above are also applied to the method illustrated in FIG. 8.

In step S810, the digital photographing apparatus 100 performs photographing using a predetermined photographing mode or a predetermined photographing function. At the same time, the digital photographing apparatus 100 accumulates usage data including a frequency of using a photographing mode or photographing function and records it in the internal memory 801.

In step S820, the digital photographing apparatus 100 may be connected to the client terminal 300 to share or back up the photographed image. In this case, the digital photographing apparatus 100 may determine whether to connect to the client terminal 300.

In step S830, the digital photographing apparatus 100 may first encrypt the use data when connected to an external device and store the data in the memory card 802. Because, in general, when the digital photographing device 100 is connected to the client terminal 300 for transmission of image data, the client terminal 300 recognizes the digital photographing device 100 as a portable storage device. This is because the internal memory 801 in which is stored cannot be accessed.

In step S840, the client terminal 200 prepares to upload the encrypted usage data stored in the memory card 802. For example, the client terminal 200 may read encrypted usage data from the memory card 802 and upload the data every time it is connected to the cloud server 300.

In step S840), the client terminal 200 transmits the encrypted usage data to the cloud server. For example, in the client terminal 300, a software module capable of accessing the cloud server 100 through the network 400 may be installed. Accordingly, the software module of the client terminal 300 reads and stores the encrypted usage data whenever it is connected to the digital photographing device 100, and can transmit the encrypted usage data when it is connected to the cloud server 100 later.

In step S860, the cloud server decrypts the received encrypted usage data. In addition, by analyzing the usage data in step S870, usability evaluation and utilization value for each function mounted in the digital photographing apparatus 100 may be determined.

Finally, in step S880, the cloud server provides the analysis result.

As described above, the usage data analysis system 10 of a digital photographing device according to an embodiment accumulates and records the photographing mode and the frequency of use of photographing functions in a plurality of digital photographing devices such as a smart phone, and analyzes it using a cloud server can do.

Accordingly, the usability evaluation and utilization value of each function mounted in the digital photographing apparatus can be determined by using the usage data analyzed by the cloud server. Furthermore, it is possible to provide customized product development and services by using it as a measure to determine the concept or direction for product development to be produced in the future.

Meanwhile, the above-described embodiments of the present invention can be written as a program that can be executed in a computer, and can be implemented in a general-purpose digital computer that operates the program using a computer-readable recording medium. The computer-readable recording medium includes a storage medium such as a magnetic storage medium (for example, ROM, floppy disk, hard disk, etc.) and an optical reading medium (for example, CD-ROM, DVD, etc.).

So far, the present invention has been looked at around its preferred embodiments. Those of ordinary skill in the art to which the present invention pertains will be able to understand that the present invention can be implemented in a modified form without departing from the essential characteristics of the present invention. Therefore, the disclosed embodiments should be considered from an illustrative point of view rather than a limiting point of view. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the scope equivalent thereto should be construed as being included in the present invention.
