摘要： Progressive authentication is generally employed to establish the authenticity of a user, such as a user of a computing device, or a user that wants to access a proprietary data item, software application or on-line service. This can entail inputting authentication factors each of which corresponds to one or multiple attributes associated with the user, or historical patterns of one or more attributes associated with the user, or both, and a confidence level that estimates a reliability of the factor. Sensor readings captured by one or more sensors are also input. Each sensor senses a user attribute and are used to quantify each authentication factor confidence level. An overall confidence level is established based at least in part on a combination of the individual confidence levels. A user is then designated as being authentic whenever the established overall confidence level exceeds a prescribed authentication level. This process can be continuous with the overall confidence level being continually updated.

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： Techniques are described for controlling availability of memory. As memory write operations are processed, the contents of memory targeted by the write operations are read and compared to the data to be written. The availability of the memory for subsequent write operations is controlled based on the outcomes of the comparing. How many concurrent write operations are being executed may vary according to the comparing. In one implementation, a pool of tokens is maintained based on the comparing. The tokens represent units of power. When write operations require more power, for example when they will alter the values of more cells in PCM memory, they draw (and eventually return) more tokens. The token pool can act as a memory-availability mechanism in that tokens must be obtained for a write operation to be executed. When and how many tokens are reserved or recycled can vary according to implementation.

摘要： Inoperable phase change memory (PCM) blocks in a PCM device are remapped to one or more operable PCM blocks, e.g. by maintaining an inoperable block table that includes an entry for each inoperable PCM block and an address of a remapped PCM block. Alternatively, the PCM blocks may be remapped by storing the address of the remapped block in the block itself, and setting a remapping bit that indicate the block has been remapped. Where the remapping is performed by a processor, an inoperable block bit may be set in a translation look aside buffer that indicates whether a virtual memory page is associated with an inoperable or remapped PCM block. When a request to access a virtual memory page is received, the processor references the inoperable block bit associated with the virtual memory page to determine whether to check for remapped PCM blocks in the inoperable block table.
摘要翻译： PCM设备中的不可操作的相变存储器（PCM）块被重新映射到一个或多个可操作的PCM块，例如。 通过维护不可操作的块表，其包括每个不可操作的PCM块的条目和重新映射的PCM块的地址。 或者，可以通过将重映射块的地址存储在块本身中来重新映射PCM块，并且设置指示块的重映射比特已被重新映射。 在由处理器执行重新映射的情况下，可以在转换旁边的缓冲器中设置不可操作的块位，缓冲器指示虚拟存储器页是否与不可操作或重新映射的PCM块相关联。 当接收到访问虚拟存储器页面的请求时，处理器引用与虚拟存储器页面相关联的不可操作块位，以确定是否检查不可操作块表中的重新映射的PCM块。

摘要： The subject disclosure is directed towards a technology by which access to a protected entity's data is controlled by a data brokerage service. The service determines whether a requesting entity has appropriate access rights to requested information, and if so, the service returns a response corresponding to the protected data. In one aspect, the protected data may be location data of a protected entity that is maintained independent of a payment instrument. The location data is used to compute feasibility information as to whether the protected entity is authorized to perform a transaction using the payment instrument.
