Embodiments of the present application provide a file processing method, a file processing device, an electronic apparatus, and a readable storage medium. The method comprises: receiving an operation request for a file, the file comprising at least two sub-files separately stored in at least two equipments; and correspondingly processing at least one sub-file of the file according to the operation request. By the solutions provided in the embodiments of the present application, since at least two sub-files of a file are separately stored in at least two equipments, original contents of the file cannot be obtained even if a sub-file in one equipment is leaked. By the solutions provided in the embodiments of the present application, the security of files can be effectively improved.

Method and device for processing file using at least two sub-files separately stored in at least two equipments

Provided are a method and an electronic device for editing text. The method includes receiving a first text from a user, wherein the first text is to be transmitted to a receiver; obtaining at least one second text that has been previously transmitted or received between the user and the receiver; identifying a first structure of the first text and a second structure of the obtained at least one second text, wherein the first structure and the second structure includes at least one of a paragraph structure and a sentence structure; and changing at least part of the first text by changing the first structure of the first text based on the second structure of the obtained at least one second text.

Text editing method and electronic device supporting same

Embodiments relate to a method of editing text that may automatically change an expression included in input text to an appropriate expression according to a social relationship with a receiver and an electronic device supporting the method. The method may include obtaining information about at least one receiver, receiving text from a user, and changing at least a part of the text according to the obtained information about the at least one receiver.

Provided is a method including: receiving an audio signal of a transmitter; detecting sensitive information in the audio signal based on content of the audio signal; encrypting the sensitive information by using characteristic information of a receiver; and transmitting the audio signal including the encrypted sensitive information.

Communication method, and electronic device therefor

Provided are device, method, and medium for generating an audio fingerprint and retrieving audio data. The device for generating an audio fingerprint includes: a coefficient extracting section partially decoding audio data in a compression area and extracting MDCT (Modified Discrete Cosine Transform) coefficients; a coefficient selecting section selecting an MDCT coefficient robust to noises from the extracted MDCT coefficients; a modulation spectrum generating section transforming the selected MDCT coefficient by the use of a Fourier transform method and generating a modulation spectrum; and a bit conversion section quantizing the generated modulation spectrum and generating an audio fingerprint. As a result, it is possible to accurately and rapidly retrieve the audio data recorded in a variety of environments. Since elements based on MP3 are used, it is possible to apply to MP3 applications in various manners. In addition, it is possible to apply to classification of audio data such as classification of music moods and classification of music genres and various other fields such as extraction of a specific event from moving images of sports.
