Electronic device translating secret word using mask character string and translation support method

An electronic device comprising:

• a controller configured to acquire data indicating first text in a first language, the first text including a plurality of character strings each with a character string attribute;
• storage configured to store a secret character string table and a mask character string conversion table, the secret character string table associating secret character strings among the character strings each indicating secret information with secret character string attributes of the secret character strings, the mask character string conversion table associating a character string in the first language among the character strings with a character string in a second language different from the first language, the character string in the first language being employed as a corresponding one of the secret character string attributes, the character string in the second language corresponding to the character string in the first language;
• and
• a communication device configured to perform communication with a translation server which translates the first text into second text in the second language, wherein
• the controller determines whether or not one secret character string of the secret character strings is included in the first text,
• upon determining that the one secret character string is included in the first text, the controller acquires a secret character string attribute associated with the one secret character string included in the first text from the secret character string table,
• the controller attaches an identifier to each of the secret character string attributes in an alphabetic order,
• the controller determines the character strings with the secret character string attributes to which the identifiers are attached to each be a mask character string, the mask character string being for hiding the one secret character string,
• the controller converts the one secret character string into a mask character string in the first language,
• in converting the one secret character string into the mask character string in the first language, the controller generates a replacement table based on the mask character string conversion table, the replacement table associating the mask character string in the first language, a secret character string in the second language, and a mask character string in the second language corresponding to the mask character string in the first language with each other, the secret character string in the second language corresponding to the one secret character string in the first language,
• the controller stores the replacement table in the storage,
• the controller transmits data indicating the first text in which the one secret character string has been converted into the mask character string in the first language to the translation server through the communication device,
• when the communication device receives data indicating the second text, the controller refers to the replacement table stored in the storage to search the second text for the mask character string translated into the second language, and
• the controller converts the mask character string in the second language into the one secret character string in the second language.
