    With the necessary knowledge, it would be technically possible to alter the recording a posteriori, but in that case, the resulting video would not match the hash summary of the original recording. Only if it is the original video it may be compared with its hash summary and have the intended evidence

  • What happens if I have multiple network devices?

    Acta de navegación only captures from one network device, at start of the capture the desktop application tries to detect the network device used for the Internet connection, in normal circumstances it shouldn’t be a problem, but if we want to be sure that we capture the correct traffic it can be done by disabling the rest of the network devices of the system prior to start the capture.

  • Why the pdf document doesn’t include the network capture?

    The network capture is susceptible to have a larger filesize than the screen capture, for that reason we decided to not include it inside the the Act to make it more manageable on systems with limited resources.
