Although the main objective of the proposed design is to increase trust in users, there are also other factors that have been taken into account, such as privacy protection, user-friendliness and usability. Thus, one of the main features of the proposal is that users who publish their trips have their privacy fully protected. Unlike other carpooling platforms, in the described system, no user is allowed to access data such as email, phone, full name or other data of another user, unless it is authenticated on the platform, and the algorithm for checking mutual trust returns a valid permission for it. In this case, the interested user will be able to see the relevant data. Otherwise, it can only submit a request to another user (driver) so that this can decide whether the applicant is reliable enough to have access to those data.
