Abstract: In an approach to obfuscation of sensitive information through non-visual feedback, responsive to receiving a signal from a user to start a session requiring input of sensitive data, one or more dummy character positions are determined, where the one or more dummy character positions represent characters that are not part of the sensitive data. Responsive to a current character position is any dummy character position of the one or more dummy character positions, the user is signaled that a next input character will be ignored, where the user is signaled using non-visual feedback. Responsive to receiving the next input character from the user, where the current character position is any dummy character position of the one or more dummy character positions, the next input character is ignored.

Abstract: Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: presenting first data on a first area of a display, wherein the first data is non-sensitive data; presenting second data on a second area of the display, wherein the second data is sensitive data; wherein the first data is displayed to feature a first viewing angle, and wherein the second data is displayed to feature a second viewing angle, wherein the second viewing angle is narrower than the first viewing angle so that a range of viewing angles from the display at which displayed data is visible is larger for the first data than for the second data.

Abstract: A method for configuring multiple displays connected to a common computing system is disclosed. In one embodiment, a computing system detects multiple displays connected thereto. The computing system causes at least one of the displays to emit a lighting pattern. This lighting pattern may include, for example, sequentially displaying a selected background color and/or pattern on each of the displays. The computing system detects the lighting pattern using one or more cameras connected to the computing system, such as cameras incorporated into the displays. Using the detected lighting pattern, the computing system infers a physical arrangement of the displays. In certain embodiments, the computing system uses artificial intelligence to infer the physical arrangement. A corresponding system and computer program product are also disclosed herein.

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.

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.

Abstract: Real time audio stream validation is provided. An audio stream of a voice communication corresponding to a call is segmented into a plurality of blocks in response to receiving the audio stream from a user. The plurality of blocks is modified to generate a first modified audio stream corresponding to the call that includes hashed values of the plurality of blocks. The first modified audio stream along with the hashed values of the plurality of blocks is sent via a network.

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.

Abstract: A first function of a first microservice and a second function of a second microservice are derived from data of an application using a plurality of microservices. From the first function and the second function, an embodiment determines that the first microservice and the second microservice have above a threshold similarity with each other. An embodiment determines a set of differences between the first microservice and the second microservice. New source code of the application is generated, the new source code utilizing the first microservice instead of the second microservice, the first microservice selected using the set of differences.
