Aspects of this disclosure provide a device, system, and method for analyzing text. In an embodiment, a system is configured to convert characters of the text into a numerical time series signal. The numerical time series signal includes a time series conversion of the characters in numerical format. The system is further configured to generate a waveform with extracted information from the numerical time series signal. The extracted information having features based on politeness in language, a quantifiable use of punctuations, a quantifiable use of conjunctions, use of idioms, or a combination thereof. The system is additionally configured to determine whether the text is written by a specific user based on an analysis of the waveform against a threshold.
[Problem] To provide a high-security file transfer system. [Solution] This file transfer system 100 comprises: a terminal 110 of a sender S, the terminal being located on a network NW1, and a storage server 120 that is on the network NW1 and that receives an email M sent from the terminal 110; an authentication server 120 and a file relay server 140, which are located on a network NW2; and a terminal 160 of recipient R, the terminal being located on a network NW3. Once the authentication server 130 completes the authentication of a recipient R, an attachment file F stored in the storage server 120 is transferred to the terminal 160 of the recipient R via the file relay server 140.
