Systems, methods, and apparatus for generating and validating product keys. In some embodiments, a product key includes security information and identification information identifying at least one copy of a software product. The identifying information may be used to access validation information from at least one source other than the product key, and the validation information may be used to process the identification information and the security information to determine whether the product key is valid. In some further embodiments, the security information includes a first portion to be processed by a first validation authority using first validation information and a second portion to be processed by a second validation authority using second validation information, wherein the second validation information is stored separately from the first validation information.

Secure software product identifier for product validation and activation

One or more techniques and/or systems are provided for securely authorizing a client to consume data and/or services from a service provider server while mitigating burdensome requests made to a validation server. That is, validation data provided to a client from a validation server may be maintained on the client and at least some of that validation data can be used to subsequently authorize the client when the client attempts to consume data and/or services from the service provider server (e.g., download a song). However, the validation data is maintained on the client and/or provided to the service provider server in a manner that inhibits user tampering. In this manner, numerous requests for validation of the client need not be made from the service provider server to the validation server when a client requests content from the service provider server, while also inhibiting unauthorized consumptions of data by the client.

Protected authorization for untrusted clients

Systems, methods, and apparatus for validating product keys. In some embodiments, a product key includes security information and identification information identifying at least one copy of a software product. The security information may include a first portion to be processed by a first validation authority using first validation information and a second portion to be processed by a second validation authority using second validation information. The second validation information may be stored separately from the first validation information and may not be accessible to the first validation authority. In some embodiments, the first validation authority randomly determines whether a product key is to be audited by the second validation authority. Alternatively, the first validation authority may determine whether to audit based on a type of the software product associated with the product key and/or a perceived level of security risk.

Reliable software product validation and activation with redundant security

One or more techniques and/or systems are provided for assigning power management classifications to a process, transitioning a computing environment into a connected standby state based upon power management classifications assigned to processes, and transitioning the computing environment from the connected standby state to an execution state. That is, power management classifications, such as exempt, throttle, and/or suspend, may be assigned to processes based upon various factors, such as whether a process provides desired functionality and/or whether the process provides functionality relied upon for basic operation of the computing environment. In this way, the computing environment may be transitioned into a low power connected standby state that may continue executing desired functionality, while reducing power consumption by suspending and/or throttling other functionality. Because some functionality may still execute, the computing environment may transition into the execution state in a responsive manner to quickly provide a user with up-to-date information.

System and method for assigning a power management classification including exempt, suspend, and throttling to an process based upon various factors of the process

A centralized process is provided for elevating portions of an application running under a user account to administrator privilege. A service security identifier is temporarily associated with the user and the portions of the application to be elevated to administrator privileges. The service security identifier is registered in the access control list to be accessed by the operating system. The centralized process may be used in the activation of software products.
