Systems and methods for reducing latency through motion estimation and compensation techniques are disclosed. The systems and methods include a client device that uses transmitted lookup tables from a remote server to match user input to motion vectors, and tag and sum those motion vectors. When a remote server transmits encoded video frames to the client, the client decodes those video frames and applies the summed motion vectors to the decoded frames to estimate motion in those frames. In certain embodiments, the systems and methods generate motion vectors at a server based on predetermined criteria and transmit the generated motion vectors and one or more invalidators to a client, which caches those motion vectors and invalidators. The server instructs the client to receive input from a user, and use that input to match to cached motion vectors or invalidators.

In other embodiments, the systems and methods cache repetitive motion vectors at a server, which transmits a previously generated motion vector library to a client. The client stores the motion vector library, and monitors for user input data.

Embodiments of the present disclosure provide methods, apparatus, and computer program products for generating an insertion netlist for a target circuit configured for inserting a malicious design alteration into the circuit based on a design identifying reference trigger nets. Features are extracted for each net identified in a netlist for the circuit. A set of reference trigger features is generated for each of the reference trigger nets. A net is selected from the netlist for each set of reference trigger features based on a similarity between the features of the net and the set of reference trigger features. The insertion netlist is generated that includes the circuit with the malicious design alteration inserted at each of the selected nets.

A method for predicting a structural failure by a strength-criterion-driven peridynamic model is provided. By building a peridynamic model driven by the strength-criterion of structural materials and then applying geometric and material parameters and working conditions of a structure, a life period from a deformation to a complete break of the structure is predicted. The method is of a high reliability, a wide application range, and a high calculation efficiency. The method simulates an initiation and a propagation of multiple cracks on complex structures under complex load conditions until the structure is destroyed.

A process to design an attitude control system (ACS) controller in each of a plurality of joined entities includes identifying a worst case configuration as a design-to configuration as one or more configurations in a given set S of configurations required for a spacecraft. For the design-to configuration, the process includes deriving one or more system equations in a functional form of equations to determine intermediate design parameters that represent effective proportional and derivative gains of the combined controller, Kp and Kd, respectively. The process also includes determining the design parameters of the ACS controller, namely, gains Kq and Kω and stiffness and damping coefficients, Ks and Cd respectively of all the interfaces between each of the plurality of joined entities, from the intermediate design parameters Kp and Kd. The process further includes programming the ACS controller with selected values of the design parameters for matrices Kq and Kω and selecting springs with stiffness Ks and dampers with damping coefficient Cd for all interfaces between each of the plurality of joined entities. The process includes iterating the computer-implemented process after incrementing a convergence requirement parameter σthreshold when the control performance is not acceptable and until the system achieves acceptable performance, and programming the ACS controller for each of the plurality of joined entities.

A method that includes providing a database for storing meta-data that describes steps in a workflow and an order of the steps in the workflow. The meta-data includes, for each of the steps: a description of an input data file for the step; a description of a transaction performed at the step; and a description of an output data file generated by the step based at least in part on applying the transaction to the input data file. Data that includes meta-data for a step in the workflow is received and the data is stored in the database. A trace of the workflow is generated based at least in part on contents of the database. The generating is based on receiving a request from a requestor for the trace of the workflow. At least a subset of the trace is output to the requestor.

An approach is provided for obscuring an individual likeness in a digital image based on a privacy policy. The approach identifies an individual whose likeness appears in a digital image taken by a digital camera with the digital image being stored. A determination is made, based on a privacy policy pertaining to the identified individual, whether to obscure the first individual's likeness in the digital image. Responsive to the determination being positive, the approach obscures the individual's likeness as it appears in the digital image.

Various systems, mediums, and methods herein describe aspects of personal information platforms accessible with client devices over communication networks in data infrastructures. A system may determine data associated with a user. The system may determine a personal information platform (PIP) based on the data associated with the user, where the PIP is configured to identify a number of data types from the data associated with the user. The system may determine accesses for one or more entities to the number of data types based on one or more services provided by the one or more entities to the user. The system may cause a client device to display an indication of the PIP, where the indication provides the one or more accesses of the one or more entities.

Empirical data concerning user responses to permission requests by applications are collected over time. The collected empirical data is aggregated and analyzed to determine whether a requested permission pertains to core functionality and/or key feature(s) of an application. Based on the result of the data analysis, a directive is then generated for a subsequent request for the same permission, to provide advice to a user whether to approve or reject the permission request.

A computer device has a kernel driver in a kernel mode of the operating system which records an access token as initially associated with a user process. Later, the user process presents its access token when requesting certain operations through the operating system. The kernel driver detects that the user process has been subject to an escalation of privilege attack by evaluating the access token in its presented form as against the initially recorded access token and, in response, performs a mitigation action such as suspending the user process.

A computer-implemented method for authentication using a hashed fried password may include receiving a password value of a user, a salt key, a pepper key, and/or a temporary and randomly generated fry key, or otherwise modifying/appending the password with the salt key, pepper key, and/or fry key. The method may include hashing the modified password, such as performing a hash operation similar to Hash (Password, Salt Key, Pepper Key, Temporary Fry Key). The randomly generated fry key is not saved or otherwise stored, either locally or remotely. A remote server attempting to authenticate the user's password may check for each possible fry key, such as checking against a set of preapproved fry keys, that the hashed fried password may have been modified with in parallel. As a result, an online customer experience requiring a password is not impacted or impeded, while an attacker's attempts to learn the password are frustrated.
