Abstract: Methods and systems for collecting execution trace data for software, analyzing execution data for software, and identifying defects in software. One method includes storing, by a processing unit, execution trace data for the software when the software is executed, storing, by the processing unit, source code for the software when the software is executed, storing, by the processing unit, a program image of the software when the software is executed, and replaying the execution of the software using the execution trace data, source code, and the program image.

Abstract: A transparent tamper-evident holographic/non-holographic security film incorporated into a check book or prescription tablet that is easily accessible when the user writes on each check or prescription sheet in the tablet. A document tablet according to one embodiment includes at least one document page and at least one security film composition bound with the at least one document page.
