Personally I don't see much benefit to an app being closed over open. However there is always the counter argument about licences. Services like Wickr have a paid aspect and if the app is fully open, it might be easier for people to replicate and use in other ways that don't gain the company money. I don't see many companies actively using closed source as an argument for security but rather to protect intellectual property and financial gain. Also it means that if someone does find a vulnerability, it might remain in the source code for a long period of time depending on how often a company performs code audits. Many will argue that this is not really security and that it hinders the trust factor for a sensitive app (such as a secure messaging app). This is often referred to as security through obscurity. Also your enemies won't know how your app operates as easily to find flaws. Being able to see how it handles your data (and that it handles it correctly) makes a user trust it more than a closed system where the user is not sure if a backdoor, spying mechanism, or other fault exists.Ĭlosed source proponents will argue that closed source makes it harder to break into because the code is harder to obtain (reverse engineering). Open source also makes people feel like they can trust the application. The theory is that because anyone can go through the source code there are more people who would spot issues and report them. Open source relies on the "many eyes" to guard against failure or bugs. Unlike other collaboration tools, which encrypt messages as they travel from a user's device to a company's servers but store those communications in an unencrypted state, Wickr uses end-to-end encryption which means that only people on either end of a conversation can decrypt and read messages.In response to the open source vs closed source debate here are some aspects I would consider: As for the actual storage protocols, the data lives on your device in an encrypted form. But don't get this wrong, Wickr is also good in this respect. Signal goes the extra mile to secure your data. The messages and files can be backed up on cloud before sending to the Wickr Me Secure Shredder which is a built-in feature of the app. Screenshots do not include any navigations away from the quiz.Ĭan Wickr messages be recovered? You can recover or retrieve deleted Wickr Me messages. Expiration timers are ideal for everyday communications.Ĭan canvas see if you took a screenshot? Even screenshots cannot be detected by Canvas. In Wickr Pro you have a wider range of options, with settings anywhere from 6 hours to 30 days. In Wickr Me, expiration timers can be set to anywhere from 6 hours to 6 days. However, we are working on an optional permission based feature that would not invade the recipients' privacy.Įxpiration timers dictate how long after a message is sent that it will be deleted. Knock knock feature (allows you to see caller's video without even picking up the call)Ĭan you tell if someone has seen your message on Wickr?Ĭurrently, Wickr does not offer read receipts.In fact, it comes pre-installed in some Android devices. Which is the most secure video calling app? Google Duo is a very famous video calling app. We're excited to share that AWS has acquired Wickr, an innovative company that has developed the industry's most secure, end-to-end encrypted, communication technology.
