Abstract: Device, system, and method of determining memory requirements and tracking memory usage. A method includes: dynamically modifying, in an iterative process including two or more iterations, a maximum size of Random Access Memory (RAM) that a Memory Protection Unit (MPU) authorizes an executable program code to access. In each iteration, the method includes running that executable program code while the MPU enforces a different maximum size of RAM, and monitoring whether the executable program code attempted to access a RAM memory address that is beyond that maximum size of RAM in that iteration. Based on such iterations, the method determines a minimum size of RAM that is required for that executable program code to run without causing a memory access fault.

Abstract: In one embodiment, a method includes receiving usage data regarding usage of a subscription-based media service account, generating a plurality of sharing scores based on the usage data, each of the plurality of sharing scores being indicative of a confidence that the usage of the subscription-based media service account is subject to a respective type of sharing, comparing each of the plurality of sharing scores to a respective threshold, and, in response to one of the plurality of sharing scores exceeding its respective threshold, presenting a challenge associated with the respective type of sharing.
