Abstract: Aspects of the invention include systems and methods configured to prevent masquerading service attacks. A non-limiting example computer-implemented method includes sending, from a first server in a cloud environment, a communication request comprising an application programming interface (API) key and a first server identifier to an identity and access management (IAM) server of the cloud environment. The API key can be uniquely assigned by the IAM server to a first component of the first server. The first server receives a credential that includes a token for the first component and sends the credential to a second server. The second server sends the credential, a second server identifier, and an identifier for a second component of the second server to the IAM server. The second server receives an acknowledgment from the IAM server and sends the acknowledgment to the first server.

Abstract: A system provides multi-modal user interaction. The system is configured to detect acoustic events to perform context-sensitive personalized conversations with the speaker. Conversation or communication among the speakers or devices is categorized into different classes as confidential, partially anonymous, or public. When exchange with cloud infrastructure is needed, a clear indicator is presented to the speaker via one or more modalities. Furthermore, different dialog strategies are employed in situations where conversation failures, such as misunderstanding, wrong expectation, emotional stress, or memory deficiencies, occur.

Abstract: An LED fabrication method includes forming release holes by focusing a laser at the substrate back surface, and forming stealth laser-blast areas by focusing a laser inside the substrate on positions corresponding to the release holes; communicating the release holes with the stealth laser-blast areas to release impurities generated during forming of the stealth laser-blast areas from the substrate through the release holes, thereby avoiding low external quantum efficiency resulting from adherence of the released material to the side wall of the stealth laser-blast areas. By focusing on a position with 10 ?m˜40 ?m inward from the substrate back side, adjusting laser energy and frequency to burn holes inside the substrate to penetrate and expose the substrate back surface, thereby effectively removing by-products, and reducing light absorption by such by-products, light extraction from a side wall of the LED can also be improved and light extraction efficiency is enhanced.
