In the last decade Digital Forensics has experienced several issues when dealing with network evidence. An analyst, which is in charge of managing evidence flowing over a network have to face problems due to the volatile nature of such information. In facts, such data may change over time, may be lying on a server out of the his jurisdiction, or geographically far from where the crime was committed.In this paper two methods to allow remote collection of network evidence produced by online services such as web pages, chats, documents, photos and videos are presented. They enable the analyst to drive the acquisition process through the online services considered potential sources of evidence. During the process, all data flowing through the network is automatically collected (i.e., all the IP packets). The second one also collects the graphical representation of the acquisition (e.g., how the browser visualizes such data). Both methods introduce a trusted third party (acting as a digital notary) which is in charge of collecting and "certifying" network evidence. Before closing the acquisition process, a detailed report of the collected evidence is generated and made available to the analyst along with the collected data. Cryptographic primitives are used to demonstrate ex post data integrity, how it has been acquired and the acquisition time.As a proof of concept two prototypes have been implemented. To enhance the Court confidence of the collected evidence, at the same time, the service could be run across multiple coordinated servers acquiring the same data from different point of the network.

“…The authors also propose using such a channel to establish the location of the appropriate steganogram, and they indicate Internet services, for instance social networks, as a carrier. Proposals of low entropy steganographic methods are presented in [7]. The first one uses file names as a hidden information carrier and requires OSNs not to change them.…”

“…However, the use of steganography has not been examined. Realizing that user images are usually processed on OSNs, Castiglione et al [21] propose the use of the name and tags of the images as an alternative means of hiding information and thereby establishing a secret communication channel. In summary, thus far there is no thorough investigation on how the processing of images on public photo-sharing sites impacts different information hiding techniques.…”

Abstract-Recently, there have been proposals to evade censors by using steganography to embed secret messages in images shared on public photo-sharing sites. However, establishing a covert channel in this manner is not straightforward. First, photo-sharing sites often process uploaded images, thus destroying any embedded message. Second, prior work assumes the existence of an out-of-band channel, using which the communicating users can exchange metadata or secret keys a priori; establishing such out-of-band channels, not monitored by censors, is difficult.In this paper, we address these issues to facilitate private communications on photo-sharing sites. In doing so, first, we conduct an in-depth measurement study of the feasibility of hiding data on four popular photo-sharing sites. Second, based on the understanding derived, we propose a novel approach for embedding secret messages in uploaded photos while preserving the integrity of such messages. We demonstrate that, despite the processing on photo-sharing sites, our approach ensures reliable covert communication, without increasing the likelihood of being detected via steganalysis. Lastly, we design and implement a scheme for bootstrapping private communications without an out-of-band channel, i.e., by exchanging keys via uploaded images.
