After Blackberry and Nokia, an application running on iPhone has come under the security scanner. The Ministry of Home Affairs has written to the Department of Telecom to disallow mobile operators from offering a specific application that destructs messages after it is read by the user.

Called Tiger Text, this application allows users to send messages, text and video, without leaving any trail. Once a sender selects the message lifespan (from 1 minute up to 30 days), expired messages not only delete from both phones, but are not stored on any server and they cannot be retrieved. The sender can also choose other options that do not exist with other texting technology such as deleting the history of the conversation or making a text message �Delete on Read,� meaning the message will disappear 60 seconds after the recipient opens the message.
