An operation terminal includes a display unit, a storage unit, and a control unit. The display unit displays, for functions included in a home appliance, operation icons individually corresponding to the functions in association with control instruction information that instructs execution of the functions. The storage unit stores information on a relationship of how large or small a selection count is, which is information on a relationship of how large or small the number of selections of each of the operation icons is. The control unit determines display positions of the operation icons in the display unit on the basis of the information on the relationship of how large or small the selection count is, and causes the display unit to display the operation icons.

A random-number generation unit generates a plurality of random numbers from a plurality of seeds. A data scrambling unit conceals concealment target data which is a concealment target by using the plurality of random numbers generated by the random-number generation unit. A transmission unit transmits concealed data which is the concealment target data concealed by the data scrambling unit to a data analysis device, and transmits any seed among the plurality of seeds to the data analysis device, after transmission of the concealed data to the data analysis device.

Methods and systems for transmitting user aggregate data to a third party, such that a privacy of the aggregated data is protected, while analytical usefulness of the aggregated data is preserved. The method including receiving, using a transceiver, aggregated data including time-series data collected over a period of time. Selecting, from a memory, a mapping for transforming a segment of the aggregated data of a predetermined size. Partitioning the aggregated data into a multiple data segments, each data segment is of the predetermined size. Transforming each data segment using the mapping to produce multiple transformed data segments, wherein each data segment is transformed by the mapping independently from other data segments. Finally, transmitting, using the transceiver, the multiple transformed data segments to a third party over a communication channel, wherein steps of the method are performed by a processor operatively connected with the memory and the transceiver.
