SPI - SECRET TEXT MESSAGES

Features SPI - SECRET TEXT MESSAGES

With privacy in daily communications becoming increasingly hard to maintain SPI offers you the freedom to ensure that, if you so wish, your messages can remain private.
It only takes a few extra seconds to convert the “plain” text message you have written into secret code.
So SPI is extremely useful both for the business world and for very personal communication between friends.To use SPI you must first agree with your correspondent(s) a well-chosen password – one that is easy to remember but near impossible to guess.
If you choose three characters then the chance of anyone guessing your password is one in a million.
If you choose 6 characters, then the chance is one in a million, million.
And if you go all the way to the maximum of 14 characters, then the chance is one in ten thousand trillion trillion.
Each password you choose can send over a million completely different coded versions of a single “plain” message.
Nevertheless, it is good practice to change your password occasionally.
Your password is not stored on your mobile, nor is any “plain” version of any message sent or received, so, if your mobile is stolen, no one can find your secrets.

Because SPI employs “end to end” encryption, it is not susceptible to “man in the middle” attacks.

SPI only uses the Short Message Service (SMS) communication system, so it will operate fully when only a 2G network connection is present.
When the agreed password is entered, you then see the encrypted message on the screen before it is sent, giving you confidence that you are not inadvertently sending a sensitive message in “plain”.
If you do attempt to send a “plain” message you will be prompted to encrypt it before it is sent.
When you open an encrypted message, you will be asked to enter your agreed password.
The “plain” readable message is then displayed on the screen but the stored message always remains encrypted.
