To prevent that, users can verify the devices they are sending messages to. Indeed, a malicious server could add a new device to a user's list of authorized devices. Once both signatures are produced, end-to-end encrypted sessions can be established with the companion device.Īuthorizing devices in this way is not enough, though, to ensure no one can eavesdrop on a user's communications. ![]() To link a companion device to a WhatsApp account, the user’s primary device must first create an Account Signature by signing the new device’s public Identity Key and the companion device must create a Device Signature by signing the primary’s public Identity Key. To authorize a new device, a user will need to scan a QR code from their phone, which can include the use of biometric data where enabled. The most obvious change is that each device has its own identity key, while users have a list of authorized devices. WhatsApp's new multi-device architecture attempts to circumvent all those issues without compromising security. This approach, while easy to implement, has a number of drawbacks in terms of user experience, says Facebook, including slow operation, dependency on the smartphone battery state, limitation to one single companion device at at time, and so on. Additional companion devices may connect to the smartphone app and mirror its contents. This is associated to a unique identity key which is used to initiate all conversations and to establish secure end-to-end connections for each user. WhatsApp's current architecture is based on the use of a smartphone app as the primary source of truth. ![]() Due to the ephemeral nature of the cryptographic keys, even in a situation where the current encryption keys from a user’s device are physically compromised, they cannot be used to decrypt previously transmitted messages. ![]() This end-to-end encryption protocol is designed to prevent third parties and WhatsApp from having plain-text access to messages or calls. To this aim, WhatsApp is adopting the Signal protocol. WhatsApp is testing its new architecture aimed to enable true multi-device message synchronization while preserving end-to-end cryptographic security.

Third parties devices for high frequency sensing costs several hundreds dollars. Unless the manufacturer processes the fast events and then sends them (once per second or less), which is very unlikely if the manufacturer does not market this feature itself. ), such battery data are sent more often once per second or less. Due to the small bandwidth(also because of other car data that have to be sent. Therefore transients evolving directly from the battery could only be recorded if the manufacturer sends those data accordingly on the bus. There are some OBD solutions, however most of them (in my experience) give back low frequency data put by the car manufacturer on the OBD-bus (CAN. , in this post) is related to those open source parts.

How to get on Spotify Playlists Infographic These can boost your stream numbers, which help propel you into more playlists. You can drive streams using a variety of growth hacks. Check out a presentation, From Pays To Plays, I wrote in 2016, anticipating the switch away from downloads towards streams. These are the modern currency of streaming. The key to gaining more listeners, resulting in more revenue, is to get onto playlists. That’s significant, as we’ll see later when we examine Spotify advertising. To save you doing the maths, that means over 185m people listen using the free, ad-funded version. The latest statistics from Spotify show they have over 144m paid subscribers and 320m total listeners. Roll on 11 years, Spotify’s reported revenue in 2020 Q3 was $1.975bn. The sales rep told us invoice number 0000001 was actually a test invoice, so we were the first company to advertise on Spotify! Shortly after, we received an invoice from them, numbered “Invoice 0000002”. We thought this was a great opportunity to strike a discounted deal with them! So, after speaking with their Sales Rep, we launched a campaign for an artist called ‘Master Shortie’. Our team was playing Spotify in the office and realised all the adverts were produced in-house and only advertising Spotify, meaning, there was no paid advertising on it yet. In early 2009 I worked at an marketing agency in London. I was already familiar with ‘Jukebox’ style music services, so after checking it out, I immediately signed up. ![]() In late 2008 a friend told me about Spotify. ![]()

Some supporters also point to what they see as the anthem’s racism, citing the song’s rarely-sung third verse and the political career of author Francis Scott Key as evidence. Most notably, Seattle Seahawks players, staff and fans linked arms during the performance of “The Star-Spangled Banner” during yesterday’s 9/11 tribute.
