Self-destructing messages are the digital equivalent of a brief note that gets shredded or burns up when you touch it. They are typically used to pass along important messages with an expiration period in which the sender has no control over what happens next or who sees it. Common uses include sending self-destructing messages to emergency contacts, instructing someone else on how to destroy a message, and submitting confidential information as evidence for law enforcement.
Theory
In general, digital self-destruction involves signals generated by a traditional sender, or the message itself.
Setting Up The System
Watch out for these potential issues: A sender’s account may get suspended, while their message is still in transit. The receiver’s device may be lost, or potentially compromised and infected with malware. The receiver may be offline when they open and/or view the private note message.
Sending The Message
The message should be short, clear, and simple. Avoid over-complicating things. Try to follow these steps to keep things straightforward:
Create a self-destructing message (i.e., message with metadata that can be used to delete it after you’re done reading it)
Set a timer for the expiration of the message. The timer will disable access to other settings, such as the text or file type.
At this point, the user should consider whether they want recipients to know that their device was infected and need not send them an apology for sending them a self-destructing message.
Receiving The Message
When a message is configured to self-destruct, it is deleted from the device when you try to open it. With a little dedication, if you change your settings careful and often, you may be able to receive messages that are also designed to self-destruct on the receiver’s end. One reason people may want such messages (e.g., Bitcoin transactions) is because they are easy to send without getting caught out by an automated filtering software at their ISP or the like.
Etiquette
If you send a self-destructing message, it is polite to let your recipient know that you are sending one. It also shows good etiquette if you let them know about any bugs or quirks you are running into in the system. If they don’t receive the message after some time and realize there is an issue with the mail, they can contact you and find out what happened.
Conclusion
Self-destructing messages are the digital equivalent of a brief note that gets shredded or burns up when you touch it. They are typically used to pass along important messages with an expiration period in which the sender has no control over what happens next or who sees it. Common uses include sending self-destructing messages to emergency contacts, instructing someone else on how to destroy a message, and submitting confidential information as evidence for law enforcement.
