For the communication between the Anonymization Layer and the Reputation System a simple line based protocol is used. The Reputation System acts as a TCP server and listens on 127.0.0.1 port 4444. All commands are sent by the Anonymization Layer. All commands and responses end with a single newline ("\n" in C).
- newuser n
- A new user with index n has been added.
No response from the Reputation System. - feedback n m x
- User n sent a feedback about user m with value x.
No response from the Reputation System. - kcabdeef n m x
- User n previously sent a feedback about user m with value x and now wants to undo it.
No response from the Reputation System. - query n m
- User n wants to query the reputation of user m.
- Response
- y, the reputation value of m as seen by n
- age a
- Introduce ageing into all previous feedback by multiplying it with a. (Creates a moving average.)
No response from the Reputation System. - n
- The anonymization layer wants to query the (e.g. the last n from a newuser command).
- Response
- n, the .
n and m are integers from the set (with being the last n sent in a newuser command).
x is from the set
a and y are real numbers, represented with the C format string g or G (with almost arbitrary precision).
