Abstract: One or more techniques and/or systems are provided for detecting stale data and/or changed data. For example, a bitmap file may be maintained and mapped to an inofile describing various states of files of a file system. The bitmap file may be populated with bitmap records indicating whether files were accessed, modified, or have other states. The bitmap file may efficiently convey information used to determine whether files have not been accessed recently (e.g., stale data) or were recently modified (e.g., changed data) compared to the inofile because the bitmap file may comprise a fraction of the size of the inofile (e.g., a byte of information may be used to represent various states of one or more files). In this way, instead of evaluating a relatively larger inofile, the bitmap file may be evaluated to efficiently identify stale data for deletion or destaging and/or changed data for backup.

Abstract: An asset management system is provided which comprises one or more controllers, which operate as main servers and can be located at the headquarters of an electronic device manufacturer to remotely control their operations at any global location. The controller can communicate remotely over the Internet or other network to control one or more secondary or remote servers, herein referred to as appliances. The appliances can be situated at different manufacturing, testing or distribution sites. The controller and appliances comprise hardware security modules (HSMs) to perform sensitive and high trust computations, store sensitive information such as private keys, perform other cryptographic operations, and establish secure connections between components. The HSMs are used to create secure end-points between the controller and the appliance and between the appliance and the secure point of trust in an asset control core embedded in a device.
