Scalar quantizer decision scheme for dependent scalar quantization
When dependent scalar quantization is used, the choice of the quantizer depends on the decoding of the preceding transform coefficient, and the entropy decoding of a transform coefficient depends on quantizer choice. To maintain high throughput in hardware implementations for transform coefficient entropy coding, several decision schemes of the scaler quantizer are proposed. In one implementation, the state transition and the context model selection are based on only regular coded bins. For example, the state transition can be based on the sum of the SIG, gt1 and gt2 flags, the exclusive-or function of the SIG, gt1 and gt2 flags, or based on only the gt1 or gt2 flag. When a block of transform coefficients is coded, the regular mode bins can be coded first in one or more scan passes, and the remaining bypass coded bins are grouped together in another one or more scan passes. |

Dynamic, runtime application programming interface parameter labeling, flow parameter tracking and security policy enforcement
A dynamic API security policy is enforced at runtime. This can be done without having access to the API specification or code. A flow of execution initiated by the API is tracked at runtime, and a data object used by the API is identified. Specific data labels are assigned to specific fields of the data object used by the API. The specific data labels consistently identify data fields of specific types. The API security policy that is enforced prohibits specific actions concerning data fields of specific types, which are also consistently identified in the security policy. Actions in the tracked flow of execution that violate the API security policy are detected at runtime, and security actions are taken in response. In some implementations, these dynamic API security techniques are supplemented with static API security analysis of an API specification and a set of rules concerning API risk assessment. |

Dynamically-tiered authentication
Techniques are described herein for dynamically-tiered authentication, which allows the authentication tier (AT) associated with a session to be automatically downgraded based on the session satisfying one or more downgrade criteria. Automatically downgrading a session eliminates some authentication-based privileges for the session without eliminating all privileges for the session. A session satisfies downgrade criteria based on: an explicit request for session downgrading; client interaction with the application; and/or activity on the device on which the client runs. For example, if a client authenticates to a third AT, but only performs actions in the application that are associated with the first AT during a pre-defined amount of time, the AT associated with the session is automatically downgraded. The session is either downgraded from the third AT to the first AT, or downgraded in intervals until the current or more recently accessed tiers are consistent with the current AT of the session. |

Detecting a skimmer via a vibration sensor
Disclosed herein are system, method, and apparatus for detecting a skimmer via a vibration sensor on a transaction card. The method includes receiving, at a server, from a user equipment, vibration information recorded by a transaction card in response to an execution of a transaction at a point-of-service (POS) terminal of a plurality of POS terminals using the transaction card. The vibration information may be recorded by a microphone or an accelerometer on the transaction card while the transaction card is swiped through the POS terminal or inserted into or removed from the POS terminal. The method includes determining, at the server, a state of the POS terminal based on the received vibration information and in response to a determination of the state of the POS being compromised, sending to one or more stakeholders of the transaction a warning message containing the POS terminal information including the POS terminal's state. |

Image synthesis for personalized facial expression classification
A method may include obtaining a facial image of a subject and identifying a number of new images to be synthesized with target AU combinations and categories of intensity. The method may also include synthesizing the number of new images using the facial image of the subject as the base image with the number of target AU combinations and categories of intensity with a number of new images that have different AU combinations than the facial image of the subject. The method may additionally include adding the number of new images to a dataset and training a machine learning system using the dataset to identify a facial expression of the subject. |

Document search for document retrieval using 3D model
Technologies are described for reconstructing physical objects which are preserved or represented in pictorial records. The reconstructed models can be three-dimensional (3D) point clouds and can be compared to existing physical models and/or other reconstructed models based on physical geometry. The 3D point cloud models can be encoded into one or more latent space feature vector representations which can allow both local and global geometric properties of the object to be described. The one or more feature vector representations of the object can be used individually or in combination with other descriptors for retrieval and classification tasks. Neural networks can be used in the encoding of the one or more feature vector representations. |
