How did 1984 George Orwell used personal prestige ideas to control the citizenship?

If I'm reading your question right, I think any personal identity was frowned upon by the party.

What do you mean by that?

Can you explain more?

Personal prestige was looked upon by the Party as individuality. The party only wanted attention to be giving to Big Brother and the party. All prestige went to the party. There was to be no individuality among outer party members.
