    Abstract: An apparatus and method for a sensor network, machine-to-machine (M2M) communication, machine type communication (MTC), and Internet of things (IoT) are disclosed. The disclosure may be applied to, for example, intelligent services related to the above technologies, in conjunction with smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security, and safety related services. The method includes generating first image data by resizing original image data to a predetermined size, inserting watermark data into the first image data, and adding difference data corresponding to the difference between the original image data and the first image data to second image data that is image data in which the watermark data is inserted.

    Abstract: Provided are a method and apparatus for encoding an audio signal and a method and apparatus for decoding an audio signal, in which errors generated during encoding and decoding of the audio signal are reduced to enhance the audio quality of a reconstructed audio signal. The method of encoding the audio signal includes detecting a pitch of the audio signal, determining a filter coefficient based on the detected pitch, performing second filtering on the audio signal, based on the determined filter coefficient; and encoding an audio signal resulting from the second filtering.

    Abstract: Exemplary embodiments may provide a method of encoding an audio signal. The method includes: segmenting the audio signal into a plurality of frames, wherein each of the frames includes M samples and M is a natural number greater than one; applying a first window, a second window, and at least one third window to the frames, wherein a length of the second window is longer than a length of the first window, and a length of the third window is longer than the length of the first window and shorter than the length of the second window; time-frequency transforming the frames to which the first window, the second window, and the at least one third window have been applied; and generating a bitstream including the time-frequency transformed frames.
