Abstract: Resource access credential security is improved by providing authentication tools and techniques which do not rely on embedment of credentials in the source code or configuration files of programs that use the credentials to access secured resources. A program under development in a development tool determines through the operation of authentication code that it is under development and that a developer identity is to be used to obtain access credentials, instead of using an identity of the program itself as occurs when the program is not under development. The development tool may be stand-alone, or may be in an integrated development environment, and may be extensible or not. The program may be an application, a web service, or other software, and may be deployed to a cloud or other networked environment. Authentication may be based on a selected developer identity or selected account or other subscriber data.

Abstract: A system comprising a polarization CMOS image sensor, at least one processor and a non-transitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by the at least one processor, cause the system to perform actions including receiving, from the polarization CMOS image sensor, polarization information and two-dimensional image information. The polarization information is processed using a machine learning model to generate an output that indicates whether the polarization information represents a valid biometric measurement of a physical feature of a subject.
