  • Patent number: 11632397
    Abstract: A method, computer program product, and system includes a processor(s) obtaining an authorization failure from a target application because an access request was denied based on insufficient permissions of a user. The processor(s) institutes a mock interface with a visual appearance of the target application. The mock interface displays predefined data and the target application displays dynamic data, from the server(s) executing the target application. The processor(s) obtains, via the mock interface, a request to change the permissions of the user to the target application, which includes a selection, by the user, through the mock interface, of one or more individual permissions displayed in the mock interface. The processor(s) automatically generates a customized security policy comprising the selection, where based on applying the customized security policy, repeating the access request results in authorized access to the target application.

  • Patent number: 11600235
    Abstract: Embodiments relate to coordinating operation of an under-display camera and a portion of a display panel over the camera to reduce impact of light emitted from the display panel during light sensing periods of the under-display camera. Depending on the level of light in the surrounding of an electronic device, the light emission period of the display panel and the light sensing period of the under-display camera are adjusted. The timing of the light emission period and the light sensing period are controlled so that a row of pixels in the display panel is not in the light emission period when corresponding row or rows of sensors in the under-display camera are in the light sensing period. In this way, the under-display camera may capture images without the influence of light emitted from the display panel.

  • Publication number: 20230068875
    Abstract: The present invention provides a chip packaging structure and a chip packaging method. Compared with an existing method of joining an encapsulation layer with a dielectric layer, adhesion between the encapsulation layer and a chip in the present invention is increased, and the encapsulation layer is less likely to fall off under stress. Furthermore, during the packaging process, a passivation layer enables chips to be mutually fixed together, which can prevent the chips from being shifted during the encapsulation process, and thereby enhance the reliability of the final product and improve the yield of the final product.

  • Publication number: 20230042683
    Abstract: A computer-implemented method, system and computer program product for improving understandability of text by a user. A final word vector for each word in a sentence of a document is computed, such as by averaging a first word vector and a second word vector for that word. Furthermore, elements of a user portrait are vectorized. A distance is then computed between a vector for each word in the sentence and a vectorized element in the user’s portrait which is summed to form an evaluation result for the element. An evaluation result is also formed for every other element in the user’s portrait by performing such a computation step. A “final evaluation result” is then generated corresponding to the evaluation results for every element in the user’s portrait. The document is then transformed in response to the final evaluation result indicating a lack of understanding of the sentence by the user.

  • Publication number: 20230021661
    Abstract: In implementations of the subject matter as described herein, there is provided a method for forgery detection of a face image. Subsequent to inputting a face image, it is detected whether a blending boundary due to the blend of different images exists in the face image, and then a corresponding grayscale image is generated based on a result of the detection, where the generated grayscale image can reveal whether the input face image is formed by blending different images. If a visible boundary corresponding to the blending boundary exists in the generated grayscale image, it indicates that the face image is a forged image; on the contrary, if the visible boundary does not exist in the generated grayscale image, it indicates that the face image is a real image.
