Hi,
As mentioned, here is my approach towards the full anonymization project.
- Introduce a new model EmailMapper with attributes
- ForeginKey to Address / User
- seed, A 40 bit hash,unique
- nuses, number of times this hash is used,max 5 or 10
- The approach is to encrypt the seed nuses times, with encryption
algorithms like AES, each time the email ID is displayed.
- The email ID is displayed as <nuses><encrypted seed>
- The email is decrypted nuses times to find the parent seed and thereby
point to the exact email address.
- A new seed should be generated for the user after a fixed number of
attempts,say 5 or 10,as the repeated encryption routines can slow down the
system.
The outcomes
- Everytime the user sends a message,his from address changes.
- At the same time, each of the from addresses point to the same user.
- The sender can use any stored address he has,like in the mail
contacts,repeatedly, to contact with a user,as it has nuses attached with
it.
If this approach seems viable or if I am missing something important,please
let me know.If this is fine, I would build an app that can demonstrate this
functionality, before building my application.
