摘要： Techniques to provide evidence-based dynamic scoring to limit guesses in knowledge based authentication are disclosed herein. In some aspects, an authenticator may receive an input from a user in response to a presentation of a personal question that enables user access to a restricted resource. The authenticator may determine that the input is not equivalent to a stored value, and thus is an incorrect input. The authenticator may then determine whether the input is similar to a previous input received from the user. A score may be assigned to the input. When the input is determined to be similar to the previous input, the score may be reduced. Another request for an input may be transmitted by the authenticator when a sum of the score and any previous scores of the session is less than a threshold.

摘要： Architecture that implements error correcting pointers (ECPs) with a memory row, which point to the address of failed memory cells, each of which is paired with a replacement cell to be substituted for the failed cell. If two error correcting pointers in the array point to the same cell, a precedence rule dictates the array entry with the higher index (the entry created later) takes precedence. To count the number of error correcting pointers in use, a null pointer address can be employed to indicate that a pointer is inactive, an activation bit can be added, and/or a counter, that represents the number of error correcting pointers that are active. Mechanisms are provided for wear-leveling within the error correction structure, or for pairing this scheme with single-error correcting bits for instances where transient failures may occur. The architecture also employs pointers to correct errors in volatile and non-volatile memories.

摘要： Techniques are described for device locking with activity preservation at a specified level within a multi-level hierarchy of device states. Such locking enables a user to share a device with another user while specifying a particular level of access to the device, such as access to a particular class of applications, a specific application, or a specific task within an application. Determination of the authorized activity may be based on a currently active application, or on the particular user gesture. The level of functionality made available may be based on the number of times a user gesture is repeated. Gestures may include a selection of a hardware or software control on the device, issuance of a voice command, and the like.

摘要： A processing apparatus calculates and applies calibrations to sensors that produce quasi-sinusoidal, quadrature signals, using fixed or programmable electronic circuits, a circuit to calculate the phase and magnitude corresponding to the two input (quadrature) signals, and a circuit for accumulating the number of cycles of the input signals. The apparatus also includes a circuit to generate Gain, Offset, and Phase calibration coefficients by comparing a phase space position of a measured phasor with the position of an idealized phasor whose locus in phase space is a circle of predetermined radius with no offset. The calculation of the coefficients occurs without user intervention, according to a pre-programmed rule or rules. The apparatus also includes a circuit to apply the Gain, Offset, and Phase calibration coefficients to the measured quadrature signals xi and yi according to predetermined formulae using scaling coefficients, offset coefficients and a phase coefficient

摘要： A Metadata server described herein is configured to generate a metadata table optimized for data durability and recovery. In generating the metadata table, the metadata server associates each possible combination of servers with one of the indices of the table, thereby ensuring that each server participates in recovery in the event of a server failure. In addition, the metadata server may also associate one or more additional servers with each index to provide added data durability. Upon generating the metadata table, the metadata server provides the metadata table to clients or servers. Alternatively, the metadata server may provide rules and parameters to clients to enable those clients to identify servers storing data items. The clients may use these parameters and an index as inputs to the rules to determine the identities of servers storing or designated to store data items corresponding to the index.

摘要： Techniques for providing intuitive feedback to a user regarding which applications have access to a data stream captured by a privacy-sensitive device, such as a camera, a microphone, a location sensor, an accelerometer or the like. These techniques apprise the user of when an application is receiving potentially privacy-sensitive data and the identity of the application receiving the data. In some instances, this feedback comprises a graphical icon that visually represents the data stream being received and that dynamically alters with the received data stream. For instance, if an application receives a data stream from a camera of a computing device of the user, the described techniques may display an image of the video feed captured by the camera and being received by the application. This graphical icon intuitively alerts the user of the data stream that the application receives.

摘要： The disclosed electronic processing apparatus calculates and applies calibrations to sensors that produce quasi-sinusoidal, quadrature signals. The apparatus includes either or both of fixed and programmable electronic circuits. The apparatus includes a circuit to calculate the phase and magnitude corresponding to the two input (quadrature) signals. The apparatus also includes a circuit for accumulating the number of cycles of the input signals. The apparatus also includes a circuit to generate Gain, Offset, and Phase calibration coefficients, wherein the circuit compares the phase space position of the measured phasor with the position of an idealized phasor, the locus of the idealized phasor in phase space being a circle of predetermined radius with no offset. The calculation of the coefficients occurs without user intervention, according to a pre-programmed rule or rules. The apparatus also includes a circuit to apply the Gain, Offset, and Phase calibration coefficients to the measured quadrature signals xi and yi according to the formulae Xi=(xi+Oxi+Pi×yi)×Gxi Yi=(yi+Oyi)×Gyi where Gxi and Gyi are the scaling coefficients, Oxi and Oyi are the offset coefficients and Pi is the phase coefficient and where Xi and Yi are the post-calibration quadrature signals. The apparatus also includes a circuit that creates an output signal representative of the current, calibrated phase. The output signal is either a parallel, digital word or one or more serial pulse trains wherein the total number of pulses produced over time corresponds to the total phase change in the measured signal. The output signal is coded to allow phase decreases as well as phase increases.
