  • Patent number: 11972623
    Abstract: An approach for enhancing a video stream. The approach processes a video stream and identifies frames comprising text. The approach marks text extraction locations and extracts the text from the frames. The approach determines if a mirroring effect should be applied to the text and applies if applicable, creating enhanced text. The approach inserts the enhanced text and smooths the edges of the inserted enhanced text. The approach merges the frames with the enhanced text into the video stream, creating an enhanced video stream and sends the enhanced video stream to requesting users.

  • Patent number: 11856147
    Abstract: A computer-implemented method for detecting and concealing confidential communications is disclosed. The computer-implemented method includes determining an audio output source used by a participant of an audio conference is unidentifiable. The computer-implemented method further includes responsive to determining that the audio output source used by the participant of the audio conference is unidentifiable, transmitting a high frequency signal via audio conference software used by the participant to conduct the audio conference. The computer-implemented method further includes responsive to detecting the high frequency signal via a microphone of a user device used by the participant to listen to the audio conference, determining that the participant is using a speaker to listen to the audio conference.

  • Publication number: 20220358494
    Abstract: In an approach for enabling communication between offline devices to perform secure transaction, a processor sends information in an optically recognizable first code including a response type, an identity of the first device and a type of optical reader associated with the first device. A processor receives encoded information in an optically recognizable second code. A processor extracts a user identifier and the one-time password associated with the registered second device. A processor determines that a user certificate associated with the user identifier exists in a local repository. A processor validates the one-time password associated with the registered second device with the user certificate using a public certificate associated with the first device, the one-time password associated with the registered second device and the one-time password seed. A processor authenticates the user.
