Finally, we discuss how to analyze and correlate the data stored in the databases used by ChatSecure to identify the \ accounts used by the user and his/her buddies to communicate, as well as to reconstruct the chronology and contents of the messages and files that have been exchanged among them. Furthermore, we show how this passphrase can be identified and extracted from the volatile memory of the device, where it persists for the entire execution of ChatSecure after having been entered by the user, thus allowing one to carry out decryption even if the passphrase is not revealed by the user. We show that ChatSecure stores local copies of both exchanged messages and files into two distinct, AES-256 encrypted databases, and we devise a technique able to decrypt them when the secret passphrase, chosen by the user as the initial step of the encryption process, is known.

Far from taking users as a homogeneous and undifferentiated mass, we distinguish between the low-risk users that appear in most usability studies (such as university students in the USA and Europe) and high-risk activist user-bases in countries such as Ukraine and Egypt where securing messages can be a matter of life or death.Ībstract We present the forensic analysis of the artifacts generated on Android smartphones by ChatSecure, a secure Instant Messaging application that provides strong encryption for transmitted and locally-stored data to ensure the privacy of its users. We'll overview some common protocol design questions facing developers of secure messaging protocols and test the competing understandings of these questions using STS-inspired interviews with the designers of popular secure messaging protocols ranging from older protocols like PGP and XMPP+OTR to newer unstandardized protocols used in Signal and Briar. In the domain of secure messaging, the sometimes subtle choices made by protocol designers tend to elude the understanding of users, including high-risk activists.
This feature has proved invaluable for journalism sourcing.-As secure messaging protocols face increasingly widespread deployment, differences between what developers " believe " about user needs and the actual needs of real-existing users could have an impact on the design of future technologies. Unlike other cryptographic protocols which produce output that can later be used as a verifiable record of communication, OTR provides complete confidentiality and "deniable encryption" in essence, a snooping entity cannot prove that two parties had an Internet chat conversation or said anything specific. The OTR protocol keeps conversations private. These applications make use of Off-the-Record Messaging (OTR), a cryptographic protocol for encrypting instant messaging applications.

The answer lies in using free third party applications that encrypt your messages. But, there are ways to thwart Facebook's default chat recording feature. Unfortunately, Facebook is the most popular social network in the world, so simply avoiding it may not be possible, which would be the easiest way to deal with this matter. And, the fact that spies like the NSA and law enforcement agencies can access your Facebook chats on a whim, should be reason enough to find a way to conduct private, unrecorded conversations on Facebook. You also may not want confidential business information or an intimate personal conversation falling into the wrong hands. There are many reasons you may not want to keep a record of your chats, the most basic being that privacy is a basic human right.
