Abstract: Disclosed are various embodiments for detecting replay attacks in voice-based authentication systems. In one embodiment, audio is captured via an audio input device. It is then verified that the audio includes a voice authentication factor spoken by a user. If it is determined that the audio includes unexpected environmental audio in addition to the voice authentication factor that has been verified, one or more actions may be performed.

Abstract: Disclosed are various embodiments for updating account data with multiple account providers. Account management logic determines that data associated with a user has been updated. A validation procedure is performed on the updated data. Multiple accounts of the user that may use the data are determined. The accounts are with multiple account providers. Corresponding account update requests for the accounts are sent to the account providers. The account update requests specify the data that has been updated.

Abstract: Methods and systems for implementing dynamic rate adjustment for interaction monitoring are disclosed. At an entity, the collection of trace information is initiated according to a first sampling rate. The trace information is indicative of interactions between the entity and one or more additional entities. A second sampling rate is determined based at least in part on information external to the entity. The second sampling rate is determined after the collection of the trace information is initiated at the entity according to the first sampling rate. At the entity, the collection of additional trace information is initiated according to the second sampling rate.

Abstract: Computing devices are disclosed that include functionality for providing a trustworthy indication of software integrity. The computing devices include a hardware trust evaluation device capable of determining the trustworthiness of computer programs executing on the devices. At least one trust indicator is also connected to the hardware trust evaluation device for providing an external indication of the trustworthiness of a computer program. Additional security information regarding the trustworthiness of the computer program may be displayed on the primary display device of the computing device. The display of the security information is triggered by a user of the computing device submitting a request through a secure mechanism, where the request is unobservable and inaccessible to programs executing on the computing device. Additional secure mechanisms, such as a unique user interface for displaying the security information, can be utilized to ensure the authenticity of the displayed security information.

Abstract: Disclosed are various embodiments for detecting replay attacks in voice-based authentication systems through the use of watermark signals. In one embodiment, audio is captured via an audio input device. It is then verified that the audio includes a voice authentication factor spoken by a user. A watermark signal is detected as present in the audio, which indicates that the voice authentication factor was replayed from a recording. One or more actions may then be performed.

Abstract: Disclosed are various embodiments that perform confidence-based authentication of a user. An identification of a user account is obtained from a user, and a minimum confidence threshold is determined. Multiple authentication challenges are presented to the user. Responses are obtained from the user to a subset of the challenges, with each response having a corresponding authentication point value. A confidence score is generated for the user, where the confidence score is increased by the respective authentication point values of the correct responses. The user is authenticated as being associated with the user account in response to determining that the confidence score meets the minimum confidence threshold.

Abstract: Methods, systems, and computer-readable media for implementing interaction reconstruction in a service-oriented system are disclosed. Routes are stored for a first set of service interactions between individual services in a service-oriented system. The routes comprise data indicative of call paths for node identifiers in the first set of service interactions. A sparse trace is generated for a second set of service interactions between individual ones of the services. The sparse trace comprises a plurality of node identifiers in the second set of service interactions. Based on the node identifiers in the sparse trace and the node identifiers in the plurality of routes, the sparse trace is matched to one or more of the routes.

Abstract: Disclosed are various embodiments for creating and manipulating chained entity identifiers that include multiple use case-specific entity identifiers. Each of the use case-specific entity identifiers may identify a single entity but may differ, as they are use case-specific. Further, each of the use case-specific entity identifiers may be encrypted and/or signed using different use case-specific keys. The use case-specific entity identifiers may be nested or appended within a chained entity identifier.

Abstract: Disclosed are various embodiments for optimizing automated data entry by recognizing invalid data items and providing alternatives. An electronic form that requests a plurality of data items is received. The data items are automatically provided to the electronic form using stored data and/or automatically generated data. It is automatically detected that a particular data item is deemed invalid for the electronic form. In various embodiments, a suggestion for providing a valid data item may be extracted from the electronic form. An alternative data item is then automatically provided to the electronic form in place of the particular data item based at least in part on the suggestion.

Abstract: Methods, systems, and computer-readable media for implementing automated services capacity modeling using call tracing are disclosed. A plurality of demand drivers are determined based on trace data for service interactions between services in a service-oriented system. The demand drivers are determined to drive a generation of service calls to a particular service. A total call volume is determined to the particular service based on the external demand drivers. An optimized quantity of computing resources to provide the particular service is determined based on the total call volume.
