Trust Management

Besides content confidentiality, the management of the trust relationship between sender and recipient over its lifetime proves to be as important: starting from the trust bootstrapping process to ease of use when established, to revocation and recovery in case of trust changing events and usability once it is established. PrivaSphere manages trust in all exchanges conducted by email and over the web.

Trust color coding:

system error: Image missing for trust level 7 Trusted Validated recipient - no change of the trust relation has occurred.
system error: Image missing for trust level 4 Non-validated system participant This recipient is a registered user and will become trusted after your first message exchange protected by a MUC). After first viewing the message with the MUC, the recipient will access the message with his account password and mutual trust will be established.
system error: Image missing for trust level 2 Non-validated non-participant This user can receive single messages protected by a MUC). As long as this recipient has not chosen a password, the recipient can access the message multiple times with the MUC until the message expires.
system error: Image missing for trust level 1 Closed or deleted user This user can no longer access the messages. The account has been closed - for example because this user works for a different employer and no longer is the owner of that e-mail address.
system error: Image missing for trust level 0 trust level not determined If a message is sent via the "secure contact me"/"prepaid return envelope" feature, trust level can not be determined.



Hint: Encourage your non-validated, non-participant recipients to become participants. If the recipient clicks on the quick register button, he can obtain a password, trust with the sender is established and a MUC is not any longer needed when communicating between these two parties. Registering only to receive does not have a cost impact for the user.
