Abstract: The invention relates to a method for managing exchanges of data between: —a probe (1) comprising a memory containing a probe digital certificate including a probe public key, —a terminal (2) comprising a memory containing a terminal digital certificate including a terminal public key, —a remote platform (3) configured to: ?deliver the probe digital certificate to the probe and ?deliver the terminal digital certificate to the terminal, characterised in that the method comprises the implementation of an authentication procedure consisting of the following steps:—a first step in which the probe verifies the identity of the terminal from the terminal digital certificate; —a second step in which the terminal verifies the identity of the probe from the probe digital certificate, and—a third step in which the probe, the terminal and the platform each generate an identical session key from the probe and terminal public keys.

Abstract: Techniques for ephemeral message are described. In one embodiment, an apparatus may comprise a delayed-action worker module operative to wake according to a wake timer; determine a current update object for a delayed-action cursor for a recipient update queue for a messaging system, the delayed-action cursor associated with an action delay for the recipient update queue; determine a delayed-action activity for the current update object; perform the delay-action activity for the current update object; determine a next update object for the delayed-action cursor for the recipient update queue; and determine a next wake timer for the delayed-action worker module based on the action delay and a creation time for the next update object. Other embodiments are described and claimed.

Abstract: The disclosure is directed to a failover mechanism for failing over an application service, e.g., a messaging service, from servers in a first region to servers in a second region. Data is stored as shards in which each shard contains data associated with a subset of the users. Data access requests are served by a primary region of the shard. A global shard manager manages failing over the application service from a current primary region of a shard to a secondary region of the shard. The current primary determines whether a criterion for failing over, e.g., a replication lag between the primary and the secondary regions is within a threshold, and if it is within the threshold, the failover process waits until the lag is zero. After the replication lag is zero, the application service is failed over to the second region, which then becomes the primary for the shard.
