Security for Lost or Misplaced device – iLocate
In this fast moving world, people are always in rush. People usually carry few necessities with them, and we cannot separate mobile phones from these. For one or another reason, it sometime happens that people misplace or lose the thing, and one cannot easily afford losing the thing like mobile. People always want the mobile to be with them.
Purpose behind developing the iLocate is to provide its user to track their lost or misplaced mobile.
A simple text message from a friend’s mobile will make users mobile to ring (even if it is on Silent mode) if phone is misplaced within reachable range.
Sometimes user loses his mobile and he/she may not able to locate it through making it ‘ringing’ because mobile may not be within a reachable range. At those times application can serve the user by following ways:
A simple text message from friend’s mobile will help user to receive his phone’s GPS location information on friend’s mobile as a URL. By clicking or opening this link user will be able to see the current location of his/her mobile on Google Map.
If SIM change takes place on user’s mobile, iLocate will notify about this SIM change activity by sending text messages to friend’s mobile numbers.
Following are terms used throughout this documentation:
Pass code is a keyword that user of application sets when he uses the application for the first time. This code is then used by user for subsequent login to the application. User can’t access application without having pass code. User may change pass code any time.
White list is a list of mobile numbers of user’s friends. User may add to, remove from or change numbers defined in this list. Once user adds a number to this list, this number is recognized as a Trusted Number by iLocate, and user of this number is a Trusted User. This means that only a trusted user can send codewords from his/her trusted mobile so that application can prevent unwanted users from misusing the features of application.
A friend is a trusted user whose number exists as an entry in white list. Friend and trusted user are names that may be used interchangeably.
A codeword is a keyword that user has defined for taking a desired action when his/her mobile receives that codeword to his/her mobile, from a trusted number. iLocate has currently two kind of codewords.
- GPS Codeword: A GPS codeword is a keyword that user has defined within iLocate. When a trusted user sends this codewords from his/her trusted mobile to user’s number as a text message, application recognizes it and generates a link that can help user to view his/her location on Google Map. This link is sent back to trusted user’s mobile so that he/she can locate user’s mobile on Map.
- Ringer Codeword: A Ringer codeword is another keyword that user has defined within application. When user’s loses his/her mobile within a reachable range but due to the current profile on the mobile he/she may not be able to locate mobile, at these times a friend may help user by sending a simple text messages (we call it Ringer codeword) that will make user’s mobile ringing.
These codewords are configurable by user of application once he/she is logged in.
SIM change notification receiver
SIM change notification receiver is another list of mobile numbers of user’s friends. User may add to, remove from and change numbers defined in this list. Once user adds a number to this list, application notifies on these numbers by sending text messages when SIM change takes place on user’s mobile. Numbers in this list are also termed as Trusted Numbers.
