Secure Garbage Collection on a Mobile Device

摘要

Methods and systems for performing garbage collection involving sensitive information on a mobile device are described herein. Secure information is received at a mobile device over a wireless network. The sensitive information is extracted from the secure information. A software program operating on the mobile device uses an object to access the sensitive information. Secure garbage collection is performed upon the object after the object becomes unreachable.

主权项

1. A method for performing secure garbage collection involving unreferenced data objects on a computing device, the method comprising:
receiving information over a network; creating a first data object corresponding to the received information; storing the first data object in an addressable storage memory on the computing device; extracting a second data object from the first data object, wherein the second data object is accessible using a third data object; unreferencing the third data object; in response to determining that the third data object has become unreferenced, calling a wipe function to overwrite the addressable storage memory of the computing device where the first, second, and third data objects are stored; and reclaiming the addressable storage memory where the first, second, and third data objects were stored.
