Disclosed are an information interaction method and apparatus, and an electronic device. A specific implementation of the method comprises: acquiring a first near-field communication signal; extracting, from the first near-field communication signal, first pairing information for pairing with a multimedia conference terminal; and sending the first pairing information to a server, so as to instruct the server to determine a target multimedia conference terminal on the basis of the first pairing information and to establish a communication connection between the target multimedia conference terminal and a user terminal device. By means of the implementation, the convenience for a user to control a multimedia conference terminal is improved. In addition, the overall cost of a multimedia conference system can be reduced.

Information interaction method and apparatus, and electronic device

According to implementations of the subject matter described herein, there is provided a solution for data embedding and data extraction in images. To perform data embedding, a target region for data embedding is determined from a source image, such as a chart image. Target data to be embedded is converted into a sequence of logical values represented in a predetermined format. Based on the sequence of logical values, image values of one or more image elements in the target region are changed such that the changed image values in the target region can be used to convey the sequence of logical values corresponding to the target data. The variations in image values are within a predetermined range such that no significant data distortion of perception distortion is caused by the data embedding. In a subsequent process, the embedded data can also be easily extracted from the image for use.
