INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM

摘要

There is provided an information processing device including an acquirer that acquires second data obtained by converting first data constituted by bit data having a first number of bits into symbols having a second number of bits greater than the first number of bits, with respect to each of the bit data, a comparator that compares a first symbol string constituted by a plurality of symbols contained in the second data prior to reverse conversion of the acquired second data into the first data, to a second symbol string representing a code targeted for detection, and a detector that detects the first symbol string as the code targeted for detection from the second data, on the basis of the result of the comparison by the comparator.

1. An information processing device comprising:
an acquirer that acquires second data obtained by converting first data constituted by bit data having a first number of bits into symbols having a second number of bits greater than the first number of bits, with respect to each of the bit data; a reverse converter that generates the first data by converting the symbols constituting the acquired second data into the bit data; a comparator that compares corresponding bits of a first data string constituted by the plurality of bit data contained in the generated first data, and a second data string representing a code targeted for detection; a Hamming calculator that calculates a Hamming distance representing a number of corresponding bits of the first data string and the second data string that are not matched with each other, on the basis of the result of the comparison by the comparator; and a code detector that detects the first data string contained in the first data as the code targeted for detection when the calculated Hamming distance is equal to or less than a predetermined threshold value.
