Abstract: A camera is configured for use with a removable camera lens cover, which can be secured to or removed from the camera by a user without the use of a tool set. The mechanism which allows the lens cover to be secured to and removed from the camera includes a set of wires embedded into the lens cover and a set of wedges protruding from the lens wall of the camera. To secure the lens cover to the camera, the lens cover is placed onto the front of the camera and rotated until the wires align with corresponding wedges, securing the wires underneath the tapered surface of the wedges. To remove the lens cover from the camera, a force is applied outward and normal to the lens cover, causing the wires to flex outward and enabling the rotation and removal of the lens cover from the camera.

Abstract: A system and method for controlling multi-party communication during video conferences communicatively connects with at least two participating terminals, each manned by one participant in the conference. A voice acquisition module acquires speech and video at each participating terminal.

Abstract: An identity verification method applied in a computer device includes periodically collecting biometric data of a user. A difference between the collected biometric data and pre-stored biometric data is determined. The pre-stored biometric data is updated to be the collected biometric data, and the collected biometric data and identification information of the user are uploaded to a blockchain when the difference is greater than a preset threshold. Once current biometric data of the user is obtained, and the identification information of the user from the blockchain based on the current biometric data of the user is downloaded, identity verification is performed on the user based on the downloaded identification information.

Abstract: A method for detecting an obstacle applicable in an electronic device includes detecting whether at least one object is within a line of sight of an image capturing device. The image capturing device is controlled to capture a first image of the object and the image capturing device is caused to move until a capturing angle for capturing another image of the object is changed. The image capturing device is controlled to capture a second image of the object and a determination is made as to whether the object in the first image is the same as the object in the second image. For such recognized objects, the object is determined to be a non-planar obstacle when the object in the first image is not the same as the object in the second image.

Abstract: An identity authentication device includes a communication unit configured to establish communication with a plurality of online servers, a processor, and a storage configured to store a user profile database including a number of user profiles, wherein each of the user profiles corresponds to an online browsing habit. The processor receives an online browsing record of a user, compares the received online browsing record to the online browsing habits of the user profiles stored in the user profile database to determine whether the received online browsing record matches one of the online browsing habits, and determines whether the received online browsing record belongs to a same user of a matched one of the user profiles according to a result of comparison.
