Abstract: An electronic device is disclosed. The electronic device comprises: a camera; a storage unit; and a processor for capturing an image including authentication information of an external electronic device through the camera, acquiring first information related with a public key included in the image and storing the first information in the storage unit, and comparing second information with the first information so as to authenticate the external electronic device when the second information and identification information related with the public key are received from the external electronic device on the basis of a type of first information.

Abstract: An electronic device is provided. The electronic device includes an input/output interface, and one or more processors configured to output a user authentication information restriction through the input/output interface, determine user input characteristics, based on user authentication information input based on the user authentication information restriction, and output, through the input/output interface, the user authentication information restriction updated based on the determined user input characteristics.

Abstract: The system allows identifying new Internet advertising with minimal human participation. Also, the system provides a module for heuristic generation of rules for the found advertising, which makes it possible to automate the process of maintaining the relevance of lists of Internet advertising blocking rules. The system can operate in two modes: the mode of finding new advertising and generating rules for it and the mode of automatic data collection (datasets) for learning. The distinctive feature of the system is a comprehensive approach to the analysis of ad units that includes visual appearance of images (color contrast, element layout patterns, etc.), link analysis, and html code analysis.

Abstract: A system of the present invention allows to determine the likelihood that a certain block of a web page is an advertising, such as a banner or a native advertising. The system uses combined and holistic approach to the analysis of units for the purpose of finding the advertising features (links, images and HTML code). The system does not impose any restrictions on possible ways of using it—it only provides tools for determining the probabilities of the unit belonging to the advertising or non-advertising class.
