This invention discloses a brain-computer interface (BCI) smart zoom glasses and a visual adaptive adjustment system, relating to the field of smart glasses technology. It includes an EEG signal acquisition module that attaches to the user's head to collect signals, extracts feature vectors after noise reduction, and transmits them to a core control module; a visual environment perception module that collects target and environmental data, generates structured data packets, and transmits them synchronously; a core control module that integrates multi-source data, identifies visual intent, and decides on adjustment parameters; a smart zoom execution module that adjusts the lens focal length and provides closed-loop feedback to calibrate accuracy; a visual adaptive adjustment module that adjusts lens parameters based on the environment and fatigue state; a human-computer interaction module that supports manual operation, status display, and vibration feedback; and a data storage and update module that stores data and iteratively optimizes the model. This invention achieves accurate visual intent recognition through brain-computer interaction; personalized modeling adapts to different user needs, meeting the product development and application requirements of the wearable smart device manufacturing field.

This application relates to the terminal field, and discloses an application icon displaying method and a terminal to resolve a problem that when a terminal includes a plurality of cloned applications of an application, application icons on a home screen of the terminal sharply increase, and consequently space of the home screen is occupied and a problem the applications have cloned applications is also exposed. A specific solution is applied to a terminal including at least two applications. The at least two applications include a first application and a cloned application of the first application. The terminal displays a first screen, where the first screen includes an icon of a first application, and an icon of the cloned application of the first application is hidden. The terminal receives a first operation performed by a user on the icon of the first application, and displays the hidden icon of the cloned application of the first application in response to the first operation, where the icon of the cloned application of the first application and the icon of the first application are simultaneously displayed on the first screen, and the first screen is included on a home screen of the terminal.

The present invention provides a method and system for deduplication of users, and relates to the field of mobile communications. The method comprises: issuing a statistical request to request the number of users to be counted; issuing a desensitization level confirmation request according to the statistical request to request the confirmed desensitization level to be sent; confirming the request according to the desensitization level and sending the confirmed desensitization level; determining the desensitization level for calculation according to the confirmed desensitization level, and extracting trajectory data from the blockchain according to the desensitization level for calculation to perform deduplication calculation and obtain the number of users. In the present invention, accurate deduplication statistics can be performed on mobile terminal users across operators.

Provided are a privacy protection method for a transmitting end and a receiving end, an electronic device, and a computer-readable storage medium. The method includes acquiring an initial image, acquiring an area to be scrambled in the initial image, performing backup and scrambling for the initial image based on the area to be scrambled to obtain a scrambled image and backup information, encrypting the backup information to obtain an encrypted result, and transmitting the scrambled image and the encrypted result.
